Regarding the function of platelets, they secrete procoagulants, or clotting factors, which promote blood clotting. So option C is correct.

Platelets are small, disc-shaped cell fragments in the blood that play an important role in the process of blood clotting.

When a blood vessel is damaged, platelets aggregate at the site of injury and release procoagulants, also known as clotting factors, which promote the formation of a blood clot.

The clot helps to stop bleeding and prevent further damage to the blood vessel. This is a crucial function of platelets that helps to maintain the integrity of the circulatory system and prevent blood loss.

The theory that says weight is maintained through internal regulatory controls making it difficult to lose weight is called the c)set-point theory.So,correct option is c.

Set point theory, in accordance with human body weight, expresses that there is a natural control technique in people that effectively manages weight towards a foreordained set load for each individual. This might happen through guideline of energy consumption (e.g.via expanded or diminished hunger) or energy use (for example by means of diminished digestion or sensations of lethargy).

Set point theory clears up why it is hard for health food nuts for keep up with weight reduction over the long run, as calorie limitation might turn out to be less viable or more challenging to keep up with as administrative systems in the body effectively push the body back towards the set point weight.

Set point theory separates between dynamic pay and uninvolved remuneration. In dynamic pay, an administrative component in the body influences energy consumption or admission. In latent remuneration, a reduction in muscle to fat ratio levels prompts a diminishing in energy pay even without an administrative component as there is less weight to be conveyed. Set point theory places dynamic pay likewise toward inactive compensation.

Membrane proteins function as b. All of these

The cell membrane is the outermost layer of the cell that limits the environment inside the cell to the outside environment. The cell membrane is also useful as a barrier to organelles in cells and fluids that limit cells. The cell membrane is composed of protein and two layers of lipids called the phospholipid bilayer, which is where the proteins are spread between the two layers.

Membrane proteins are proteins that are permanently bound and give shape to cells. The function of membrane proteins is to facilitate the movement of substances in and out of cells, therefore membrane proteins act as selectively permeable channels.

Hemorrhagic stroke seems to have affected the greatest amount of brain tissue.

What is hemorrhagic stroke?

A hemorrhagic stroke, which can be fatal, is caused when a blood artery in the brain bursts and starts to haemorrhage. Your brain's regular blood flow may be hampered, depriving some regions of oxygen. Blood buildup also exerts pressure on nearby brain regions, causing harm or even death.

When you have a hemorrhagic stroke, your brain or the area around it bleeds heavily. There is only so much room for the bleeding to go because this is taking place inside of your skull. That damages the surrounding brain tissue by applying too much pressure to it. The pressure will destroy those brain cells if it is too high or remains high for an extended period of time, harming the brain permanently.

Larger arteries like the pulmonary artery or the dorsal aorta feed into increasingly smaller diameter arteries, arterioles, and capillaries as the arterial system transports blood away from the heart.

In humans and the majority of other animals, an artery (plural arteries) (from Greek (artr) 'windpipe, artery') is a blood channel that transports blood from the heart to one or more areas of the body (tissues, lungs, brain etc.).

The umbilical and pulmonary arteries, which transport deoxygenated blood to the organs that oxygenate it, are the two exceptions to the rule that most arteries deliver oxygenated blood (lungs and placenta, respectively).

Answer:

it's true

Because the walls of the veins are thinner and less rigid than arteries, veins can hold more blood. Almost 70 per cent of the total blood volume is in the veins at any given time.

This result suggests that the phage mutant and the wild-type (WT) phage are in competition for the same bacterial host cells.

When both phages are present, they compete for the same host cells, leading to the formation of smaller plaques, which indicate a lower number of bacterial lysis events compared to when only the WT phage is present. This is because the presence of the mutant phage reduces the efficiency of the WT phage in infecting and lysing bacteria, and vice versa.

Small plaque formation in this scenario is a result of reduced efficiency of either the mutant phage or the WT phage in infecting and lysing bacteria, leading to a reduction in the number of phage particles produced and hence the size of the plaque.

The result is an example of the phenomenon of phage interference, where the presence of two or more phages can affect each other's ability to infect and lyse bacteria, leading to reduced efficiency of one or both phages. This phenomenon can have important implications for the use of phages as a tool for biocontrol and for the evolution of phages and their interactions with bacterial hosts
