Red blood cells usually live for about 120 days before they die and need to be replaced. Sickle cells are fragile — their membranes break apart easily, causing the cells to die after only 10 to 20 days. The result in those with sickle-cell disease is a chronic shortage of red blood cells known as anemia.

Based on this information, why do people with anemia become easily fatigued?

Answers

Answer:

When people have anemia, their body doesn't produce enough red blood cells. They don't get enough oxygen, which makes them feel fatigued and can also cause serious health complications.

Answer:

Deforestation

1) Scientific evidence shows that deforestation provides the conditions for the spread of a variety of deadly diseases, including the Nipah and Lassa viruses, as well as the parasites that cause malaria and Lyme disease.

Population

2) Increasing population growth causes a large number of people to migrate to urban areas with industrialization.This leads to polluted air, water, noise, and the population in big cities and towns.

Oil Spill

3) Oil spills can be extremely harmful to the environment. When oil spills into the oceans, it can cause big problems. It can harm sea creatures, which can make seafood unsafe to eat.

Soil erosion

4) Soil erosion leads to increased pollution and sedimentation in streams and rivers. Soil gets degraded, the risk of erosion increases, and the sediments sweep into rivers and nearby regions, possibly contaminating nearby ecosystems.

Coral reef degradation

5) Coastal areas become increasingly vulnerable to storms, hurricanes, and cyclones when coral reefs perish. The ocean will be unable to absorb as much CO2 without coral reefs, resulting in more CO2 being released into the atmosphere.

Illegal mining

6) Mining can pollute air and drinking water, harm wildlife and habitat, and permanently scar natural landscapes.

What type of chemical is formed when proteins are broken down?​

Answers

Answer:

Amino Acids

Explanation:

During digestion, enzymes in our bodies break the proteins we eat down into amino acids (by hydrolysis). These amino acids are transported around the body by blood. In the bloodstream, condensation reactions build the amino acids up to produce proteins required by the body.

When proteins are broken down, amino acids are formed as the amino acids are joined together by the peptide bonds, and the peptide bond is formed between the amino group and the carboxyl group of the amino acids.

What is the significance of the peptide bonds and the proteins?

Peptide bonds and proteins are both significant, as the peptide bonds are formed by the amino acids, and the amino acids unite to make the protein. The breakdown of proteins in the body is a continuous process, as in this process new proteins are formed and the protein structure depends upon the amino acid composition.

Hence, when proteins are broken down, amino acids are formed as the amino acids are joined together by the peptide bonds, and the peptide bond is formed between the amino group and the carboxyl group of the amino acids.

A The cell will stay the same
B The cell will shrink
C he cell will burst open
D The cell will swell

Answers

Answer:

C

Explanation:

This must be C

According to the properties of osmosis, the cell will burst. So the correct option is C.

What is osmosis?

Osmosis is the spontaneous diffusion or flow of water or other solvents over a membrane that is semipermeable and prevents the passage of solutes, or dissolved compounds. The crucial biological mechanism was initially in-depth investigated in 1877 by German plant physiologist Wilhelm Pfeffer.

Previous researchers have conducted less precise examinations of leaky membranes (such as animal bladders) and the transport of water and escape chemicals through them in opposing directions. Thomas Graham, a British chemist, coined the term "osmose," which is still used to refer to the process, in 1854.

A solution will tend to become more diluted by absorbing solvent through a membrane separating it from the pure solvent if the membrane is permeable to the solvent but not to the solute. The osmotic pressure, also known as the pressure exerted on the solution, can be raised to a certain level to halt this process.

The Dutch-born chemist Jacobus Henricus van 't Hoff demonstrated in 1886 that osmotic pressure varies with concentration and temperature roughly as it would if the solute were a gas occupying the same volume if the solute is so dilute that its partial vapor pressure above the solution obeys Henry's law (i.e., is proportional to its concentration in the solution.

Therefore the correct option is C.

preganglionic neurons of the autonomic nervous system are located in

Answers

The cell bodies of symapathetic preganglionic neurons are located in the visceral efferent (lateral gray) column of the spinal cord.

Preganglionic neurons of the autonomic nervous system are located in the lateral gray horns of the spinal cord.

What is the function of preganglionic neurons?

The function of the preganglionic neurons is to activate nicotinic receptors on the postganglionic neurons through the utilization of a neurotransmitter known as acetylcholine.

During the process of transmissions in the autonomic nervous system, the preganglionic neurons significantly liberated acetylcholine at its ganglion. This is the first stage at which transmission is triggered with respect to the response.

The preganglionic neurons of the autonomic sympathetic nervous system are normally found within the region of the spinal cord especially, in the lateral gray horns with its axon subsisting at the ventral roots.

Therefore, preganglionic neurons of the autonomic nervous system are located in the lateral gray horns of the spinal cord.

What occurs when there is a higher concentration of molecules on one side of a membrane and the molecules flow to the other side to balance the concentration?

Answers

Answer:

diffusion

Explanation:

The concept of diffusion states that molecules like to travel from areas of high concentration to low concentration.

Let's think about an example. Let's say you are having a party at your house and in one room there is 100 people and in the other room connected to it, there is only 10 people. What do you think is going to happen as time passes? Right, people are going to move to the room where there is less people so as to equally disperse themselves across the area. The same thing happens within our body with ions and gases.

Ions can diffuse into or out of cells based off their concentration gradients. If there are too many ions on one side, they will simply move to the other side. There are different types of diffusion. Passive diffusion and facilitated diffusion, but those are for a different conversation.

Thermal energy is transferred through conduction because

the energy moves through space from one object to another.

the energy moves between objects when their molecules collide.

the molecules have the same amount of kinetic energy.

the molecules have less energy so they share.

Explain how light, depth, and temperature affect the number and type of organisms that live in each ocean zone

Answers

Light depth and temperature can affect the number and type of organisms that live in each ocean zone because, what their needs are depend of the section of water they are in. for example if you have a nocturnal fish, and you bring it into the light it will obviously not thrive in the environment because it is the opposite of what it needs. If you have a fish that likes warmer water rather than cold water, if you were to bring them into the cold water they would not thrive either because it is the total opposite of what their needs are. And the final example is for depth, if a whale is surfaced the whole time where is it going to get its food? A whale has a specific diet, and the food that they eat is primarily found in the deeper part of the ocean not near the surface. Bottom line if these needs are not meant for each part of the marine life in the ocean, they will not thrive nor survive.
