Handedness:a.reflects the greater capacity of one side of the brain to carry out skilled motor action. b.is evident in a wide range of skills from birth. c.is a heritable trait, especially for left-handed people. d.is strongest for simple, rather than complex, skills.

Answers

Answer: a.

Explanation:

The proficiency to be more professional and confident using one hand instead of the other for activities such as writing and throwing a pitch is called handedness.

Handedness begins to develop before birth. Handedness is inheritable and  evident from early childhood. handedness is related to variations between the brain's right and left halves (hemispheres). The the left hemisphere regulates the action of right side of the body while right hemisphere controls movement on the left side of the body.

So in handedness, one half of the brain regulates more skilled motor action.

Hence, teh correct option is a.

A portal system Multiple Choice includes a functional end artery that makes an arterial anastomosis. is one in which circulation to a large organ involves only one artery and one main (portal) vein. is one in which multiple arteries converge on one organ or body region. is a simple circulatory system with an areriovenous anastomosis. is one in which blood flows through two capillary beds before being sent back to the heart.

Answers

Answer:

is one in which blood flows through two capillary beds before being sent back to the heart.

Explanation:

A portal system can be defined as a system of blood vessels having a capillary network at each end, meaning that the blood vessel starts and ends in capillaries, before finding its way back to the heart. The blood draining through the capillary bed flows via the larger vessel to supply the blood to the another structure's capillary bed.

Why do you think that concerns about the environment did not emerge in marine science until the late twentieth century?

Answers

Answer:

One possible reason why concerns about the environment did not emerge in marine science until the late twentieth century is that the study of marine science was initially focused on understanding the ocean's physical and biological processes, rather than its environmental impact. Another reason could be that the environmental issues and concerns related to the ocean were not as visible or apparent as they are today, and it was only after the negative effects of human activities on the ocean became more evident that marine scientists began to focus on environmental issues.

Different organs have different energy and metabolic fuel requirements. Match the organs listed below with the fuel sources each is able to utilize. Although fuel sources can change depending on the metabolic stage of the organism (e.g., starving vs. well-fed), here consider all potential fuel sources for each organ.A) Brain: B) Heart: C) Liver:

Answers

Answer:

Explanation:

brain-

Glucose is the major fuel for the brain metabolism to supply energy for synaptic transmissions. Average of -120g/day.However during hypoglacemia, keto bodies can be used by the brain for energy supply.

the fuel stores of the brain is very low because of high biochemical activities of the brain  which need to  be supplied with  contant fuel.Although it stores little Glycogen, most fuel supply to the brain is from the circulating glucose in the blood.

Heart.

the high  energy consuming  activities of the heart ensured that molecules with abundant energy supply e.g fatty acids from lipids digestion is preferred. Keto bodies, acetoacetate and lactate can also be fuel . Glucose is last on the scale of preference for the heart  as fuel.

It does not reserve or export any fuel.

Liver.

the complex metabolic  and multi functional activities  of the liver required constant supply of energy in all available forms. Thus  glucose, Amino acids and fatty acids are sources of fuel for the liver.

The liver fuel reserve is in the form of glycogen which is stimulated by glucagon to convert to glucose during condition of hypoglycemia. Triacylglycerols is another fuel reserve.

Generally as products of metabolic activities in the liver, fatty acid from lipid metabolisms, Glucose from gluconeogenesis, and glycogensis, and ketone bodies are the export sources.

Answers

Answer:

Inconsistencies in the data warrant further investigation

Explanation:

When you find something new and exciting in your field of study you should always investigate further to see if certain circumstances in the situation led to your findings. If you discover that all of the female amphibians in a pond lay a few days later in the spring and normally this wouldn't happen you should always see if another pond of amphibians lay around the normal time. The water temperature could affect the laying time, the predators that are around could affect laying time, the animals comfort and even that could just be when it happens for them. But double and triple checking is always ideal, so that you are able to publish and share accurate information to help other scientists  see and experience what is actually happening.

This patient's presentation is suggestive of a UTI. Given the ill appearance, vital signs, and white count, Upper tract disease (pyelonephritis) should be strongly considered. A parenteral (IV/IM) third-generation cephalosporin is the best choice of those listed for pyelonephritis, given its excellent gram negative coverage (except for Pseudomonas).

Answer: INTRAVENOUS CEFTRIAXONE

Explanation: To understand the question very well,let's critically look at the age of the infant and the presenting signs and symptoms.

The infant has a history of poor feeding,emesis(vomitting) and also there is history of irritability.there is also fever.when you look at all these,it is closely related to the signs and symptoms presented by infants with UTI ( urinary tract infection) but when you consider the vital signs of the infant (Temperature: 39.2°c, Respiratory: 40bpm,and Blood pressure: 80/50mmHg), the white blood cell count and the I'll looking appearance of the infant,

Upper tract disease that is (pyelonephritis) should be considered more because the signs and symptoms indicative of pyelonephritis are more strong than that of UTI.

Looking at the age of the infant and the severity of the presenting signs and symptoms, parenteral drug administration(intravenous/intramuscular) will act faster and will be easily absorbed and as well as easily accepted by the infant than enteral adminstration.

Looking at the options listed in the question,ceftriaxone is a third generation cephalosporin (a class of antibiotics used to treat varieties of bacteria infections) and it is so far the best drug in the treatment of pyelonephritis and also the best from the options given in the question,it's effectiveness is seen in the fact that it's gram negative coverage is excellent except in the case of pseudomonads where there is no encouraging gram negative coverage.

You are performing developmental studies during which you extract mesophyll cells from an unusual-looking leaf. In laboratory culture, individual mesophyll cells from this leaf can be induced to regenerate entire plants. How would these cells be classified

Answers

Answer:

meristematic cells

Explanation:

The cells will be classified as meristematic cells.

Meristematic cells are undifferentiated cells that are capable of actively dividing and differentiating to give rise rise various tissues/organs of a plant.

Generally in plants, meristematic cells are of three types:

Those that are capable of dividing and differentiating to give rise to above ground or below ground tissues/organs such as roots, leaves and flowers, also known as apical meristems.Those that allow rapid stem elongation and repair, especially in monocots, also known as intercalary meristems.Those that give rise to various parts of a flower, also known as flora meristems.

The cells in this case are capable of dividing and differentiating to give rise to the various organs of a complete plant. Hence, they are considered as meristematic cells.

Nonvascular plants do not have vascular tissue, while seedless vascular plants do. As a result, seedless vascular plants differ in which ways? Check all that apply.

Seedless vascular plants grow larger than nonvascular plants.
Seedless vascular plants grow smaller than nonvascular plants.
Seedless vascular plants grow closer to water sources than nonvascular plants.
Seedless vascular plants grow farther from water sources than nonvascular plants.
Seedless vascular plants have true roots, stems, and leaves.
Seedless vascular plants do not have true roots, stems, and leaves.

Answers

Vascular plants with no seeds vary from nonvascular plants in a number of ways. First off, since they have specialised tissue called xylem and phloem that aids in moving water and nutrients throughout the whole plant body, seedless vascular plants grow bigger than nonvascular plants.

Second, nonvascular plants lack genuine roots, stems, and leaves, whereas seedless vascular plants have. Finally, since they have more effective water and nutrient delivery systems than nonvascular plants, seedless vascular plants can grow farther from water sources.

Therefore, the correct response to the question is that seedless vascular plants have genuine roots, stems, and leaves, grow bigger than nonvascular plants, and spread out further from water sources than nonvascular plants.

Explanation:

A random-digit dialed survey conducted in the city of long beach, california reported that a greater proportion of nonsmokers endorsed a ban on smoking in alcohol-serving establishments than did smokers. What type of study design was this?

Answers

Answer:

The correct answer is case-control study.

Explanation:

In a case-control study, two groups of the population are used, in which one group is kept as control, and the other is known as the experimental group that encounters with a specific disease or an outcome. With the help of this study, one can expose the groups to various or single outcomes.  

In the given case, a study is done in which an advertisement on a ban on smoking is encouraged by the non-smokers at the alcohol sale points but not by smokers, in the process a random digit dialing method was used. This random digit dialing method is an illustration of a case-control study, in which the survey of the individuals is done regarding the ban on smoking.  

A study conducted via a random-digit dialed survey in Long Beach, California, assessing attitudes toward smoking bans among smokers and nonsmokers, exemplifies a cross-sectional study design.

The study described in the city of Long Beach, California, where a random-digit dialed survey reported that a greater proportion of nonsmokers endorsed a ban on smoking in alcohol-serving establishments compared to smokers, is an example of a cross-sectional study.

This type of study design involves analyzing data collected from a population, or a representative subset, at a specific point in time. In this case, the survey aimed to assess attitudes toward smoking bans among different groups within the population at a single point in time, without following up with participants over time. Cross-sectional studies are particularly useful for assessing the prevalence of behaviors or opinions in a population.

What is the ultimate fate of this subpopulation of plants? Justify your claim with the appropriate mathematics.

Answer:

the ultimate fate of this subpopulation of plants = 4

Explanation:

Given that:

Despite his young age, Ruben was recently diagnosed with hypertension. He knows that reducing dietary sodium and increasing dietary potassium can both help to lower his blood pressure. Of the following foods, which one contains the most potassium per servinga.Breadb.Bananac.peanutsd.potatoes

Answers

Answer:

Potato

Explanation:

Hypertension is a condition developed due to the continuous high or elevated blood pressure in the arteries in the body. The main cause of hypertension is the contraction of the arteries and the consumption of food with a high level of sodium and low level of potassium.

It is suggested that people with hypertension should consume a diet rich in potassium but with a low amount of sodium.  The good source of food with a high level of potassium is baked potato which provides carbohydrates also, salmon, and the banana.

Since the amount of potassium is high in the baked potato, therefore, is the correct answer.

Final answer:

Potatoes have the highest potassium content per serving among the listed foods and should be included in Ruben's diet to help manage his hypertension. It's also crucial to reduce dietary sodium to improve heart health.

Explanation:

Among the foods listed, potatoes contain the most potassium per serving. Potassium is an essential nutrient that plays a key role in maintaining proper heart function and regulating blood pressure. Ruben can benefit from eating potassium-rich foods, such as bananas, leafy greens, lima beans, and avocados, to help control his hypertension. It's also important to note that reducing dietary sodium intake and choosing foods lower in sodium can contribute to better blood pressure management.

Total recommended dietary potassium intake is 4700 mg/day. To improve the sodium and potassium balance in the diet, it's advised to avoid processed foods high in sodium and increase intake of fresh fruits and vegetables, which are generally high in potassium and other beneficial nutrients.

Replication of the lagging strand of dna is accomplished by repeatedly making __________ followed by 1

Answers

Answer:

The correct answer is "short RNA primers; Okazaki fragments".

Explanation:

The missing information of this question is as follows:

"Replication of the lagging strand of dna is accomplished by repeatedly making __________ followed by 1,000-2,000 nucleotide segments called __________"

The correct answer is "short RNA primers; Okazaki fragments".

DNA replication always occurs from 5' to the 3' end, in what is known as the directionality or the end-to-end chemical orientation in molecular biology. This fact makes difficult the synthesis of the lagging strand of DNA. In order to achieve this short RNA primers are bound to  segments of DNA (serving as the 5' end available for the DNA polymerase to synthesize), which leads to the discontinuous synthesis of Okazaki fragments that are later linked together by the enzyme DNA ligase.

The electrical impulse that stimulates neurotransmitter release, thereby transmitting information to other neurons, arise in the:
a. dendrites
b.axon hillock
c. axon
d. dendritic spine

Answers

Answer: b. axon hillock.

Explanation:

Neurotransmitter are the chemical substance which acts as a signal for neurotransmission. At a region called the axon hillock the axon emerges from the soma. At axon hillock, nerve impulses are produced by the plasma membrane; the axon pushes these impulses away from the soma, or dendrites towards other neurons.  

All the synaptic inputs are summed up at the axon hillock which further stimulates neurotransmitter release. Axon hillock is called as the trigger zone.

Hence, the correct option is b. axon hillock.

Describe how the structure of a prokaryotic chromosome differs from the structure of a eukaryotic chromosome.

Answers

Explanation:

The structure of prokaryotic chromosome differs from the structure of eukaryotic chromosome by following ways:

A prokaryotic chromosome is shorter than the eukaryotic chromosome.In prokaryotes, the circular chromosome is held in the cytoplasm in a region called nucleoid whereas in eukaryotes chromosomes are stored within a structure called the nucleus.Prokaryotic chromosome comprises only a single origin of replication whereas the eukaryotic chromosome carries multiple origins of replication.Prokaryotic chromosome consists of covalently closed (loop) circular DNA whereas the eukaryotic chromosome consists of linear DNA  not circular.

Final answer:

Prokaryotic chromosomes are circular and free in the cell cytoplasm, usually consisting of a singular chromosome. Alternatively, eukaryotic chromosomes are linear, located in the cell nucleus, and are organized into chromatin by proteins called histones.

Explanation:

The main difference between prokaryotic and eukaryotic chromosomes lies in their structure and location within the cell. Prokaryotic chromosomes are circular and found free in the cell cytoplasm, they are not enclosed by a nuclear membrane and usually consist of a singular chromosome. On the other hand, eukaryotic chromosomes are located within the cell's nucleus, and are linear in structure. These cells contain more than one chromosome, which are organized and packaged in proteins called histones forming a structure called chromatin.

Answers

Answer:

Self-fertilize to produce offspring identical to the parent

Explanation:

True-breeding plants are the breeding plants which are homozygous for the trait that is they are homozygous for the dominant trait and for the recessive trait.

This can be confirmed by making a cross between them in which they are self-fertilized. This self-fertilization produces the offsprings identical to the parents with the same phenotype.

For example:

Green pod (dominant trait)- GG

yellow pod (recessive trait)- gg

cross -  GG X gg

                    g     g

         G     Gg  Gg

All the offsprings are of green color as all have the Gg genotype in which the dominant allele is G and the recessive

       

What leads to the degradation of the contents of late endosomes by lysosomal enzymes?

Answers

Answer:

It forms with fragments of the "early endosomes" or migration endosomes, near the Golgi apparatus, it has a more central location within the cell and a slightly more acidic pH than the "early endosome". The latter will allow it to facilitate the function of the hydrolytic enzymes it receives from the Golgi apparatus, thus finally forming the lysosomes, organelles specialized in degradation.

In transport through "transcytosis", the endocited material is transported in endosomes from one end of the cell to the other, being released by the process called exocytosis.

Explanation:

Endosomes are not considered cellular organelles by many authors, but compartments within the cytoplasm that function as transporters of material in animal and fungal cells delimited by a simple clathrin membrane, mediated by a receptor in the extracellular domain at the starting site invagination; but recent literature does classify them as structures with sufficient characteristics to be considered organelles. They are defined as membranous organelles and most of the material they transport is transferred to lysosomes for degradation.

In treating alcoholism, one can condition the response of nausea and queasiness of the stomach to the sight, smell and taste of alcohol. This technique, designed to replace a positive emotional response to a certain stimuli with a negative one, is called____.

Liberia, a very poor nation in West Africa, is relatively abundant in resources such as mahogany and rubber tree forests, iron-ore deposits, and diamonds. If Liberia is so rich in valuable resources, why is it still so impoverished? a) Liberia lacks the institutions necessary to make productive use of those resources. b) The population of Liberia is too small to use those resources. c) Natural resources are not as important as other types of resources. d) Taxes in Liberia are too high and discourage investment. e) Liberians are content with a low standard of living. What was the Bessemer steel converter? How did this invention chaps U.S. history? In a rocket-propulsion problem the mass is variable. Another such problem is a raindrop falling through a cloud of small water droplets. Some of these small droplets adhere to the raindrop, thereby increasing its mass as it falls. The force on the raindrop isFext=dp/dt=m dv/dt+v dm/dtSuppose the mass of the raindrop depends on the distance x that it has fallen. Then m = kx, where k is a constant, and dm/dt=kvdm/dt=kv This gives, since Fext=mgFext=mg,mg=m dv/dt+v(kv)Or, dividing by k,xg=x dv/dt+v2This is a differential equation that has a solution of the form v = at, where a is the acceleration and is constant. Take the initial velocity of the raindrop to be zero. (a) Using the proposed solution for v find the acceleration a. (b) Find the distance the raindrop has fallen in t = 3.00 s. (c) Given that k = 2.00 g/m, find the mass of the raindrop at t = 3.00 s. Part A If the velocity of a pitched ball has a magnitude of 47.5 m/s and the batted ball's velocity is 51.5 m/s in the opposite direction, find the magnitude of the change in momentum of the ball and of the impulse applied to it by the bat. PLEASE HELP!!! I need help with this question.Which DOES NOT support the author's opinion or viewpoint that she is against the soda ban? A) The proposed soda ban is over the top. B) Sodas cause tooth decay and health concerns. C) Lets keep the soda machines and lets keep the money. D) Sodas help pay for sport programs and band programs. 1 Hi. How is everyone doing tonight? I just wanted to take a few minutes to share with you my take on the Soda Ban issue that everyone has been talking about.2 I teach seventh grade math here at the school and I think the proposed school ban on soda pop is a bit over the top. Why? Well, healthy eating habits begin at home and here at school we, as teachers, can help by encouraging healthy choices. Soda may not be the healthiest choice, but a can of soda every now and again is okay.3 We all want our children to be healthy and develop healthy eating habits. I know many of you are concerned about tooth decay and other health issues, but it's not like students are drinking soda all day long. Most students drink milk during lunch and water from the water fountain throughout the day. The vending machine room is not open in the morning, only at lunch and after school.4 At our school, all of the money from the soda machines pays for sports programs and the band program. If this ban goes into effect, where will the money come from to pay for these worthy programs? Before supporting this ban, I ask you to think about that.5 We have the best sports teams in the state. Go Hawks! We won the state football championship last year, and our tennis team did very well in the finals of the state tournament in Myrtle Beach. The tennis team has 6 players and they worked very hard in practice to be the best they can be. We have never gone all the way to the finals before, and we are very proud of our tennis team for doing so well.6 I know I have been rambling on, so let me just say every thing in moderation." Let's keep the soda machines, and let's keep the money that the machines generate going to our sports teams.

Although it is highly unlikely to happen, suppose that we suddenly discovered that all these years we'd been wrong about the distance from Earth to the Sun, and it is actually 10% greater than we'd thought. How would that affect our estimate of the distance to the Andromeda Galaxy?
