A stroke is one way that the brain can become damaged. The image above shows the
events that lead to the two types of strokes.
An ischemic stroke occurs because of an obstruction in a blood vessel supplying
blood to an area of the brain. The obstruction is the result of fatty deposits, a
condition called atherosclerosis. In an ischemic stroke, a blood clot has developed at
the clogged point or a blood clot that formed elsewhere is unable to pass through
the obstructed area. About 85% of all strokes are ischemic strokes.

A hemorrhagic stroke happens when an weakened vessel in the brain ruptures,
causing blood to leak into the surrounding brain tissue. The blood accumulates and
compresses the brain tissue.

In the picture above, which stroke seems to have affected the greatest amount of
brain tissue?

A.both seem to affect the same amount of tissue
B.ischemic
C.hemorrhagic

Under a stressful situation, the hypothalamus responds by sending signals to the pituitary gland and suprarenal gland to secrete adrenaline and noradrenaline to the bloodstream. The pituitary gland is the one that immediately activates.

The sympathetic nervous system, SNS, prepares the body for stressful situations that require an alert state or strength. It is responsible for the neural fight-or-flight response to stress.

The hypothalamus is in charge of stress responses. If the individual is exposed to a stressful situation, the hypothalamus sends signals to the pituitary gland and the adrenal medulla (suprarenal gland). The adrenal medulla secretes the neurotransmitters and hormones adrenaline and noradrenalin into the bloodstream. These hormones prepare the body for a stress response by increasing heart-biting frequency and strength, increasing blood pressure, stimulating respiration, and dilating respiratory tracts.

Once the threat factor is over, the body goes back to a balanced state.

When a person that is walking in the woods runs into a mother bear and her cubs, the gland that immediately activates is the pituitary gland and then the suprarenal gland.

The correct option is ;A   Pigments capture light energy.Photosynthesis requires pigments like chlorophyll because they can capture light energy and transfer it to electrons.

This occurs at a reaction center within the photosynthetic pigments. Plant pigments play an important role in photosynthesis, plant growth, and development (Sudhakar et al., 2016). Pigments act as visible signals to attract insects, birds, and animals for pollination and seed dispersal. Pigments also shield plants from UV and visible light damage (Tanaka et al., 2008).

There are no major functions of the heart that are not related to pumping blood or maintaining the body's blood supply. Therefore, it is safe to say that any function not related to these tasks is not accomplished by the work of the heart.

What is te main function of Heart ?

The main function of the heart is to pump blood throughout the body to deliver oxygen and nutrients to the tissues and organs and remove waste products. The heart is a muscular organ located in the chest and is responsible for maintaining the body's blood supply. It is divided into four chambers, with the two upper chambers called atria and the two lower chambers called ventricles. The heart works by contracting and relaxing in a rhythmic pattern, which creates pressure that drives the blood through the circulatory system. The heart is also involved in regulating blood pressure, maintaining fluid balance, and producing certain hormones.

The number of contractions of a contractile vacuole in one minute depends on the type of organism, but it usually ranges from 3 to 10 times per minute. The contractile vacuole is a specialized organelle found in some single-celled organisms such as protozoans.

basically It is filled with a liquid, and its main function is to pump excess water out of the cell to maintain osmotic balance. When the vacuole reaches a certain size, it will contract and expel some of the liquid, thus helping regulate the cell’s internal environment.  The frequency of contraction can vary based on the needs of the organism.

For instance, if the environment is exceptionally dry, the contractile vacuole may contract more often to expel more water. Conversely, if the environment is wet, the vacuole may contract less often. Additionally, some species, such as the amoeba, have multiple contractile vacuoles, and each will contract at a different rate depending on the organism’s needs.
