Answer 2

Bone is highly vascularized, especially in spongy bone regions. blood vessels enter bones from the Periosteum. Typically only one nutrient artery enters the bone via a small opening or hole in the bone called a nutrient foramen. Blood vessels supply nutrients and oxygen required by cells and remove waste products from bone cells.

What is bone?

The skeleton of the body is composed of living tissue, the most important of which is bone. Collagen, a type of protein, and calcium phosphate, a type of mineral, are the two primary components that make up a bone's skeleton.

Bone contains a vast network of blood arteries, which take up almost 10–15% of the cardiac output when the heart is at rest. Because of the way the blood arteries are arranged spatially, oxygen and nutrients can be transported to different parts of the bone marrow compartment in a manner that is both efficient and effective.

There are three distinct blood supply pathways that are present in a typical long bone. These are the nutritional artery, the periosteal vessels, and the epiphyseal vessels.

Plasmodium is a parasitic apicomplexan that causes malaria in humans. the figure below illustrates the plasmodium life cycle.

Answers

Plasmodium is a monocellular parasite causing malaria to humans. The parasite's life cycle always includes two hosts, an insect host and a vertebrate host. The parasite's cells are injected into the vertebrate's (human in our case) bloodstream by the insect host (mosquito). There are several stages in its life cycle but the sexual reproduction occurs only in the insect. In the insect, gametocytes (haploid gametes) merge and form a zygote which in turn becomes an oocyst. Oocysts divide multiple times and that way a great number of sporozoites is produced. These sporozoites travel to the salivary gland of the mosquito and are injected into the bloodstream of the second host, the human. In humans, sporozoites infect liver cells and red blood cells.

According to this information, the four statements about Plasmodium which are true are:
-Plasmodium cells are transferred to human cells through mosquito saliva.
-The complete life cycle of Plasmodium requires two hosts.
-Plasmodium cells infect two specific types of cells in humans.
- Inside an infected mosquito haploid gametes fuse, forming a haploid zygote that develops into an oocyst.

A localized collection of pus at the site of infection is:

Answers

I believe it is called Abscess. Abscess is a collection o pus that has built up within the tissue of the body. It characterized by symptoms and signs which include redness, pain, warmth, and swelling. The swelling may feel fluid-filled when pressed. Treatment involves drainage and antibiotics if there is a surrounding infection.

Final answer:

A localized collection of pus is an accumulation of dead pathogens, neutrophils, tissue fluid, and cells at the site of an infection, suggesting an immune response to the bacterial infection.

Explanation:

A localized collection of pus at the site of infection is typically the result of the body's immune response to bacterial invasion, where neutrophils and macrophages are recruited to eliminate the pathogen. During this process, neutrophils phagocytose the pathogens and eventually die, with their remains contributing to the accumulation of pus. Pus is therefore an accumulation of dead pathogens, neutrophils, tissue fluid, and other bystander cells that may have been killed by phagocytes at the site of the infection.

Examining bacteria under a microscope from a pus sample can provide valuable information, such as the morphology and arrangement of the bacteria, which can be critical in determining the approach for treatment. In some cases, bacterial infections can escalate if not properly treated, leading to more severe symptoms and complications, such as necrotizing fasciitis, which requires immediate medical attention.

Biological recognition is important in processes at the molecular, cellular, and organismal levels. Choose ONE of the following, explain how the process of recognition occurs, and discuss a specific example.

-Neurotransmitters are recognized in the synapse.

-Target cells respond to specific hormones.

Answers

Neurotransmitters are recognized in the synapse. In the event wherein a nerve action potential triggers the release of neurotransmitter containing synaptic vesicles from the axon of a nerve, the dendrites of the receiving nerve will recognize these neurotransmitters and trigger specific actions (i.e. excitatory or inhibitory). For instance, the release of glutamate from the synapse will trigger an excitatory response (depolarization) while the release of GABA will trigger an inhibitory response (hyperpolarization).

Target cells respond to specific hormones. Hormones are endocrine molecules that trigger specific cellular functions such as glucose uptake, urine secretion and reabsorption, etc. Hormones bind to either (1) specific hormone receptor (i.e. insulin receptors), (2) cytoplasmic receptors (i.e. thyroid hormone receptor), and (3) nuclear receptors (i.e. steroid hormones). All of which will trigger a cascade that will eventually lead to new protein synthesis (or the inhibition of such). For example, insulin binds to insulin receptors in muscle cells wherein it would trigger the synthesis of glucose channels which will facilitate the uptake of glucose.

What happens when blood glucose levels fall below normal? 1. The pancreas releases insulin. 2. The pancreas releases glucagon. 3. The pituitary gland releases insulin. 4. The pituitary gland releases glucagon.

Answers

Answer:

2. the pancreas releases glucagon

Explanation:

its not 1 because insulin is used to decrease blood glucose levels.

its not 3 because the pituitary gland does not produce insulin and insulin is not needed

its not 4 because the pituitary gland does not release glucagon.

it IS 2. because the pancreas DOES produce glucagon and GLUCAGON is needed to move GLUCOSE into the blood stream.

When the levels of sugar levels in the body fall below the normal level, the pancreas releases glucagon. Therefore, option "B" is correct.

What is the function of the glucagon hormone?

Glucagon is a peptide hormone. it is a glucose-regulatory hormone. it is released by the pancreas. When the levels of glucose drop in the blood it works against the insulin by stimulating the hepatic cells for the production of glucose. This results in an increase in levels of glucose to normal levels.

Insulin hormone is released when the levels of sugar are high in the blood to lower it whereas glucagon is released when the levels of sugar are low in the blood to bring it to normal.

Therefore, glucagon increases the levels of glucose when falls below normal levels.

During an action potential, the rapid decrease in sodium ion permeability and the simultaneous and rapid increase in potassium ion permeability is responsible for __________.

Answers

The answer is repolarization. In the first phases of an action potential,
Sodium ions flow into the cell, through the voltage-gated ion channels, causing depolarization from the resting potential of -70 mV. In the later stages of the action potential, the potassium ion selective filter channels open and potassium ions move from inside of the cell to the outside. This repolarizes the cell before sodium ions begin to be pumped out of the cell.

The answer is: the repolarization of the cell.
Muscle and nerve cells use action potentials to communicate and send signals. Nerve cells have a resting membrane potential which is a negative concentration gradient, meaning that there are more positively charged ions outside the cell compared to the inside of the cell. These positively charged ions are sodium ions, therefore, there are more sodium ions outside the cell and more potassium ions inside the cell. Repolarization of the cell is a process that happens during action potential and it comes after the depolarization of the membrane. During repolarization, the membrane potential changes and returns to the negative value of the resting potential. At this phase, the sodium channels close and the potassium channels open, causing the nerve cell to lose positively charged ions.

How do ions and electrical charges play a role in communication with the muscle?

Answers

The electrical charge that travels along the motor neuron is caused by depolarization. Depolarization is caused by the inflow of Na+ ions into the neuron. At the neuromuscular junction, depolarization causes Ca2+ ions to enter the post-synaptic neuron. Binding of Ca2+ to sensor protein in the neuron causes the neuron to release neurotransmitter acetylcholine into the synaptic cleft. The neurotransmitter binds to ionotropic receptors on the sarcolemma of the muscle fiber causing contraction of the muscle fiber.

About half of all babies are able to walk independently by __________ months of age.

Answers

I think that about half of all babies are able to walk independently by 12 month of age. It said that babies tend to take their first steps from the age of 9. Babies usually start to crawl before they can walk. This is because their arm are usually more effective. After crawling they learn to stand up with their feet first and later learn to walk while holding things. The next step after that is walking.
Not all babies walk at the same time. There those that learn before the other so there is no need to worry if your child does not walk by 12 months.

Mountains are a geographical feature found in many biomes. the rain shadow effect is where ________.

Answers

Mountains generally act as the headwaters of rivers. Clouds moving along a weather frontal system are advected to a higher altitude when they encounter mountains, causing condensation and rainfall. Unfortunately, in most parts of the world, weather patterns follow a common direction most of the time. Therefore, when the clouds encounter the mountain range, it is usually from one direction. This results in the majority of rainfall falling only on one side of the mountain, and the mountain acting as a barrier preventing cloud systems from carrying moisture across the mountain.

The production and consumption of atp during photosynthesis and cellular respiration. be detailed in where atp is made, and where it may be used both in photosynthesis and cellular respiration.

Answers

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide in the process of respiration, which is then used in photosynthesis. While water is broken down to form oxygen in photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. ATP is manufactured as a result of several processes including fermentation, respiration and photosynthesis.

Answer:

The correct answer is "photosynthesis and cellular respiration are two independent processes, ATP is produced and consumed in both processes".

Explanation:

Photosynthesis and cellular respiration are two independent processes, ATP is produced and consumed in both processes During photosynthesis the complex ATP synthase produces ATP by the biological process known as chemiosmosis. On the other hand, intermediate processes that takes place during photosynthesis require the consumption of ATP, for instance during the Calvin-Benson cycle. Cellular respiration are a series of metabolic reactions where ATP is produced and consumed as well. During cellular respiration most ATP is produced by the ATP synthase located in the mitochondria, whereas ATP is consumed in some steps of the glycolysis process.

The characteristic that all lipids have in common is that _____. see concept 5.3 (page 72)

Answers

Final answer:

Lipids all have the characteristic of being hydrophobic, meaning they repel water. They are composed of hydrocarbon chains that do not dissolve in water. Examples include fats and phospholipids.

Explanation:

The characteristic that all lipids have in common is that they are hydrophobic, meaning they repel water. Unlike other biological molecules, such as carbohydrates and proteins, lipids do not dissolve in water. This is because lipids are composed mostly of hydrocarbon chains, which are nonpolar and do not form hydrogen bonds with water molecules.

For example, fats, which are a type of lipid, consist of three fatty acid chains attached to a glycerol molecule. The fatty acid chains are hydrophobic, while the glycerol molecule is hydrophilic. This creates a structure that repels water.

Other types of lipids, such as phospholipids found in cell membranes, also have a hydrophobic region and a hydrophilic region. The hydrophobic tails of phospholipids face inward, away from the watery environment, while the hydrophilic heads face the water. This arrangement helps to form the structure of the cell membrane.

The following is a multi-step reaction. the rate-limiting step is unimolecular, with a as the sole reactant.

Answers

I) from the information given, that the rate-limiting step is unimolecular with A as the sole reactant, the rate law of the reaction is therefore;
Rate = k[A]
If you double the concentration of A, the rate of the reaction wil also double to 0.008 M/s

ii) The concentration of B has no effect on the rate of reaction, and therefore halving the concentration of B, will not change the rate of reaction. Thus the reaction rate remains 0.0040 M/s

iii) Increasing the concentration of A by 4-fold also increases the rate of reaction by 4-fold to (0.0040 ×4) = 0.016 M/s. This is because the rate of reaction depends on the concentration of A, therefore any change in this concentration affects the rate of reaction, such that an increase in the concentration of A cause a corresponding increase in the rate of reaction and vice versa.

Answers

Final answer:

Bottled water can contain harmful compounds like Bisphenol A (BPA), Fluoride, Benzene, Toluene, and Xylene, originating from the manufacturing process and contamination from industrial activities. Chlorinated compounds are used as disinfectants but don't successfully eliminate all organisms. Furthermore, water close to industrial areas often contains contaminants, including chemicals and untreated waste.

Explanation:

Bottled water can contain several toxic compounds, the source of which mostly come from the process of bottling and industrial contamination of water sources. Some notable examples are Bisphenol A (BPA), which is used in the manufacturing of hard plastics and may contaminate the water within the bottle; Fluoride which, although beneficial in small amounts, can have adverse health effects when consumed in large quantities; and harmful chemicals used in the fracking industry, such as Benzene, a carcinogen, Toluene, a system depressant, and Xylene, a neurotoxin.

Chlorinated compounds are used as disinfectants, but they may irritate the skin, eyes, and nasal passages, and they may not completely eliminate certain organisms. Cryptosporidium, for example, is a hardy protozoan parasite that can survive in chlorinated water.

Water in proximity to industrial activities or human settlements often becomes contaminated with chemicals, radioactivity, heat, and untreated waste leading to compromised water quality.

the diploid number of chromosomes in horses is 64. what is the haploid number of chromosomes in horses?

Answers

The haploid number of the chromosomes should be 32.

Diploid number means that they have the complete sets of chromosomes in their cells, these cells are usually found in somatic (body) cells and different organisms have a different number. For example, a human somatic cell has 46 chromosomes, such as a muscle cell, or a skin cell etc.

Meanwhile, haploid number means that the number of chromosomes in the cell only have half of the chromosome number than that of the diploid cells. These haploid cells are usually found in gametes of sexually reproducing organisms, such as human, we have 23 chromosomes in our sex cells. This is important because we have to make sure the chromosome number of offsprings are not doubled, as during sexual reproduction, male and female gametes fuse together to form a zygote.

Therefore, to calculate the haploid number of a cell, we can divide the diploid number by 2, which is 64/2, and the answer would be 32.

32 is the answer for sure
