What is the largest single part of the sharks nervous system?

1 answer:

5 0

The largest single part of the shark's nervous system is the brain. Sharks are one of the smartest organisms that thrive in the deep sea. They have specially evolved brains that are capable of hunting and communicating with other sharks. Their keen sense of understanding helps them understand information presented to them and then later on converting this into information that they can use in the future.

Isovolumetric relaxation and ventricular filling (two phases of the cardiac cycle) take place during __________. Isovolumetric r

Helga [31]

Answer:

Option B, ventricular diastole

Explanation:

Ventricular diastole also termed as ventricular relaxation consists of two phases. In the first phase, the following set of events takes place –

a) Relaxation of ventricle muscles

b) Reduction in pressure of blood within the ventricles

c) As this reduced blood pressure gets lower than that of pressure with in the pulmonary trunk and aorta, blood starts flowing back towards the heart.

d) A small dip in the blood pressure is observed at this stage

e) Volume at this stage remains constant as the atrioventricular valves remain closed

f) This phase is known as isovolumic ventricular relaxation phase

In the second phase, the following set of events takes place –

a) Relaxation of ventricular muscle

b) Dropping of pressure of the blood within the ventricles lower than that of pressure of blood in the atria

c) Blood starts flowing from atria into the ventricles thereby opening the tricuspid and mitral valves

d) Both the heart chambers chambers are in diastole,

e) Atrioventricular valves are open

f) Semilunar valves remain closed

Hence, option B is correct

During hemostasis, which process occurs first?

taurus [48]

Hemostasis is a process which would cause for bleeding to halt and is the first step in healing wounds. During hemostasis, the process that happens first would be vascular spasm. The damaged vessels are constricted which would result to reducing the amount of the blood flowing in the area thus limiting blood loss. This action is stimulated by factors like direct injury to a smooth muscle. This would allow chemicals to be released by the platelets and the endothelial cells. This response would be more effective as the damage is being increased. Also, it occurs more effectively in areas where there are smaller blood vessels.

The products of mitosis normally ______________

Anarel [89]

Answer:

The correct answer will be option-C

Explanation:

Mitosis is a type of cell division used by the organisms to produce the same or identical daughter cells to their parent cell.

The mitosis process forms two identical daughter cells from a single parent cell and the identical cells produced contain the same genetic material or same ploidy number as of parent, the reason also known as the equational division.

Since the daughter cells are clones to their parent cell with the same genetic and cytoplasmic content, therefore, Option-C is the correct answer.
