Answer:

C. competition eliminates species when disturbance is rare.

Explanation:

Intermediate disturbance hypothesis aims to explain the species diversity in an area. According to it, intermediate level of disturbance is required to maximize species diversity.

In case of high level of disturbance like deforestation or forest fire, all species are at risk of going extinct. In case of low level of disturbance, interspecific competition for resources increases due to which one species becomes dominant and another nearly extinct, thus reducing species diversity. Hence, an intermediate level of disturbance is required to maximize species diversity.

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.

The answer is B. They protect the burn from infection.

Hope this helps (:

Skin grafts are beneficial in treating third-degree burns by providing a permanent skin layer, protecting the burn from infections, and shortening the healing time. Option 1, 2 and 3.

The benefit of using skin grafts in treating third-degree burns is manifold. Firstly, skin grafts provide a permanent layer of skin for the burned area, which helps restore the skin's natural barrier function. Secondly, they protect the burn from infection, since burnt skin is highly prone to infections that can lead to severe complications. Thirdly, they contribute to a shorter healing time for the treated area. Timely application of skin grafts can reduce the likelihood of prolonged wound healing, which in turn can minimize scarring and improve functional and cosmetic outcomes.

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.

Tidal bulges are created by the gravitational interaction between the Earth and the Moon, resulting in a differential force that affects the Earth's oceans. This results in two tidal bulges - one on the side facing the moon and another on the opposite side.

Tidal bulges are primarily formed due to the gravitational interaction between the Earth and the Moon. This interaction causes a differential force which affects the water in the Earth's oceans. On the side of the Earth facing the Moon, this differential force makes the water flow towards it creating one tidal bulge.

On the opposite side, gravitational force is weaker and the inertia of the water causes it to bulge out, forming the second tidal bulge. Effects from the Sun, rotational forces from the Earth, and the shape of the coastlines and ocean basins can further complicate tidal patterns.The tide-raising forces, acting over a number of hours, produce motions of the water that result in measurable tidal bulges in the oceans.

Answer

the answer would be... Mark!

Explanation:

Due to the Enhance fujita scale (EF) an EF 1 would do minor damage resulting in some downed trees, power lines, and some mobile houses off their structures. On the category side though a category 5 hurricane would cause catastrophic damage. If you look back to EF1 tornadoes and category 5 hurricanes you can see the damage it has done, a giant difference.

Have a great day (or night!)

Mark has the correct statement that a category 5 hurricane causes more damage than an EF-1 tornado.

Hurricanes and tornadoes are both natural disasters, but they differ in their size, duration, and destructive power. A category 5 hurricane is the most severe hurricane on the Saffir-Simpson scale and has sustained winds of 157 mph or higher, while an EF-1 tornado is a relatively weak tornado with wind speeds of 86-110 mph.

Hurricanes also have a much larger diameter and longer duration than tornadoes, which can cause more widespread damage over a larger area.

Answer:

Evolution is the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth. Coevolution is the influence of closely associated species on each other in their evolution.

Explanation:

Final answer:

Evolution is the gradual change within a species over time, while coevolution is the mutual evolutionary influence between two interdependent species, such as in predator-prey relationships or mutualistic interactions like flowering plants and their pollinators.

Explanation:

The difference between evolution and coevolution is that evolution refers to the changes that occur within a species over time due to environmental changes, natural selection, and genetic drift, among other factors. In contrast, coevolution involves two or more species influencing each other's evolutionary path, typically because they are interdependent, such as in symbiotic relationships or predator-prey dynamics. For instance, the coevolution between flowering plants and their pollinators, where the plant evolves specific traits to attract certain pollinators, and the pollinators evolve adaptations that allow them to more effectively access the flowers' nectar or pollen. A notable example is the close relationship between some insects and flowering plants; insects have developed specialized body structures to reach nectar, while flowering plants have evolved unique shapes and colors to attract these insects.

a. ​food pellet

Explanation:

In classical conditioning, an unconditioned stimulus is the stimulus that naturally elicits an unconditioned response. The unconditioned stimulus is usually paired with a neutral stimulus, and after pairing with a neutral stimulus, the neutral stimulus becomes a conditioned stimulus that elicits a conditioned response alone.

In the experiment described above in the question, the unconditioned stimulus is the food pellet, which naturally elicits the response of the rat to wait at the far left corner of the cage. The neutral stimulus which is paired with the food pellet is the vanilla scent, which now becomes the conditioned response, when paired alone.

Explanation:

Here is the correct format of the equation in the question.

A subpopulation of plant, isolated from the main population, is found to obey the function below, describing the number of individuals (in thousands).

[tex]N_{(T)} = \frac{8e^{4T}-2T+5}{7+2e^{4T}}[/tex]

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:

[tex]N_{(T)} = \frac{8e^{4T}-2T+5}{7+2e^{4T}}[/tex]

Taking the limit of N(T) ; we have ,[tex]\lim_{T \to \infty} N(T)[/tex]

[tex]N(T) = \frac{8-\frac{2T}{e^{4T}}+\frac{5}{e^{4T}}}{2+ \frac{7}{e^{4t}}}[/tex]

where T is less than [tex]e^{4T}[/tex] ; which is written as :

[tex]T< e^{4T}[/tex]

∴  [tex]\lim_{T \to \infty} N(T )= \frac{8-2 \lim_{T \to \infty} \frac{T}{e^{4T}} +5 \lim_{T \to \infty} \frac{1}{e^{4T}} }{2+7 \lim_{T \to \infty} \frac{1}{e^{4t}} }[/tex]

= [tex]\frac{8}{2}[ \lim_{T \to \infty} \frac{T}{e^{4T}} =0 ; \lim_{T \to \infty} \frac{1}{e^{4t}} }=0][/tex]

where; [tex][ \lim_{T \to \infty} \frac{T}{e^{4T}} =0 \ \ \ and \ \ \lim_{T \to \infty} \frac{1}{e^{4t}} } = 0][/tex]

Then, [tex]= \frac{8}{2}[/tex]

= 4

Thus, the ultimate fate of this subpopulation of plants = 4

Answer:

D. Urine of a male mouse attracting a female

Explanation:

Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to impact the behavior of the receiving individuals. There are alarm pheromones, food trail pheromones, sex pheromones, and many others that affect behavior or physiology.

Bees, wasps, ants, moths and other insects rely largely upon pheromones as a means of communication. Pheromones are chemical substances which may be secreted in urine, dung or produced by special glands.

Pheromones mediate many of the complex interplays within colonies of social insects such as bees, wasps, and ants.

Pheromones are chemical signals that have evolved for communication between members of the same species. A pheromone signal elicits a specific reaction in the receiver, for example, a stereotyped behavior (releaser effect) or a developmental process (primer effect). Some pheromones can have both effects. All sorts of molecules, large and small, have been found acting as pheromones, depending on whether the message is sent out on wind or water currents or placed directly on the nose or antenna of the recipient.

Most pheromones are detected by the sense of smell. However, not all smells are pheromones. Mammals, including humans, also give off a cloud of molecules that represent our unique individual "smell" or chemical profile. These differences between individuals make it possible for dogs to distinguish people by smell. People are quite good at it, too—parents can distinguish their baby from others by smell alone. Ants similarly can distinguish between members of their own colony and those from other colonies. In both mammals and insects, learning is necessary to develop this ability. The sources of the molecules that make up an animal’s "individual smell" include its own secretions and also may reflect its environment, food, bacteria, immune system, and molecules picked up from other individuals in its social group

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.

1. A) The percentage increase in population in Hildago between 1997 to 2007 is:

Given that Hildago population in 1997 = 511, 324

Hildago population in 2007 = 726,604

Hence, the percentage increase is 726,604 - 511,324 = 215280

Then 215280 ÷ 726604 = 0.2962 ≈ 29.62%

1. B) For Willacy

Willacy population in 1997 = 19,332

Hildago population in 2007 = 20,600

Hence, the percentage increase is 20,600 - 19,332 = 1268

Then 1268 ÷ 20600 = 0.0615 ≈ 6.15%

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.

6. This protein is found in the nucleus of cells and plays an important role in the multiplication and destruction of cells. ... The p53 gene is a type of tumor suppressor gene.

Cell cycle arrest:

P53-mediated cell cycle arrest at the G1 / S checkpoint, when DNA damage is recognized, to prevent replication. It can be considered the main response when DNA damage occurs. The cell cycle arrest in the G1 / S transition is due to p53-dependent transcription of the CDKs inhibitor or also (CDC), cyclin-dependent kinase] called CDKN1A / p21. p21 inhibits CDK-cyclin complexes and prevents phosphorylation of pRb, so that transcription factor E2F remains inactive, and cell progression to the S phase (DNA synthesis) is prevented. This "pause" in the progression of the cell cycle gives time to repair DNA damage.

7.The Philadelphia syndrome or chromosome is an abnormality found on chromosome 22 of the body, and was discovered in 1960 by Philadelphia scientists Peter Nowell and David Hungerford; Both scientists worked in two different laboratories, but both were in the city of Philadelphia, and that is why this syndrome is named after the city in which they both discovered it.

This anomaly is linked to cancer because when presenting this anomaly of chromosomes 9 and 22, there seems to be a relationship with chronic myeloid leukemia. The truth is that, according to numerous studies carried out on patients with chronic myeloid leukemia, 90 percent of patients with this disease presented the anomaly of the Philadelphia syndrome.

The Philadelphia chromosome genetic defect consists of a phenomenon known as translocation, that is, a chromosomal break occurs in two specific regions of chromosome 9 and 22 (translocation 9-22), exchanging their positions. Specifically, the breakpoint occurs in the ABL gene (Abelson) on chromosome 9 (region q34) and in the BCR gene (Breakpoint Cluster Region, ) on chromosome 22 (region q11), giving rise to an altered chromosome 9 and a chromosome 22 also altered (Philadelphia Chromosome), but characterized by the fusion of these two genes (BCR-ABL), which encode a chimeric protein. The ABL gene takes its name from "Abelson," the name of a virus that causes leukemia, a precursor to a protein similar to that produced by this gene.

The following questions are answered below.

Explanation:

1. The following statement is not true for the reproductive system is it includes both internal and external reproductive structures.

2. Fertilization of ovum most often occurs in the oviduct or fallopian tube.

3. The primary hormone is responsible for development and maintenance of female sex characteristics is estrogens.

4. The layer of the uterus from which tissue is sloughed during mensuration is the endometrium.

5. The cremaster muscle raises and lowers the testes to maintain proper temperature for sperm production.

6. The period of pregnancy during which the basics of all major organ systems appear is the first trimester.

7. The last major organ(s) to mature during fetal development is/are the brain.

8. After undergoing meiosis, an egg and sperm each contain 23 chromosomes, while a developing fetus contains 46.

Final answer:

The reproductive system is responsible for the production and transport of gametes, but it does not produce hormones like GH and ADH. Fertilization typically occurs in the fallopian tube, estrogen is key for female characteristics, the cremaster muscle regulates testes temperature, the fetus grows rapidly in the third trimester, organ systems appear in the first trimester, the lungs mature last, and post-meiosis, gametes carry 23 chromosomes each, combining to form a zygote with 46.

Explanation:

The reproductive system performs critical functions for the perpetuation of species, including humans. Let's examine the questions about it sequentially:

Answer:

A general decrease in transcriptional activation

Explanation:

When acetyl groups are added to histone proteins by acetyltransferase enzymes, the 30-nm chromatin fiber will not be formed because the proteins are prevented from doing so. This further destabilizes the chromatin structure and allows the occurrence of transcription. However, raising the cells to  40°C does not allow the acetyltransferase enzyme to function and hence the acetyl group will be hindered from being added to the histone protein which is the main target of the enzymes. Thus, transcription activation will be blocked because the chromatin and nucleosomes would remain stabilized.

D. Intravenous ceftriaxone

Explanation:

Intravenous ceftriaxone

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.
