The answers are:
1. Adrenal gland:
This structure secretes adrenaline, noradrenaline, cortisol, and aldosterone.
The adrenal gland is located above each kidney. It has two parts:
Adrenal Cortex - secretes cortisol and aldosterone.
Adrenal Medulla - secretes adrenaline and noradrenaline.
2. Pineal gland/Pineal body:
This structure regulates the sleep cycle and other biological rhythms.
The pineal gland is located in the middle of the brain. It secretes the hormone melatonin, which regulates the wake and sleep cycle.
3. Thyroid gland:
This structure is located at the throat and regulates metabolism.
The thyroid gland is found in the neck. It produces thyroid hormones that regulate metabolism. It also helps maintain blood pressure, heart rate, digestion, muscle tone and other reproductive functions.
4. Pancreas:
This structure secretes glucagon and insulin.
The pancreas is located in the abdominal cavity, behind the lower part of the stomach. It secretes glucagon and insulin to regulate the glucose level in the blood.
5. Thymus gland
<span>This structure regulates the development and differentiation of T lymphocytes.

The thymus gland can be found in the thoracic cavity, in the mediastinum to be exact. T-lymphocytes are produced in the bone marrow, but they develop in the thymus.
6. Parathyroid glands
This structure regulates blood calcium levels.
They come in two pairs and are embedded on they thyroid gland. It releases parathyroid hormone. This hormone helps regulate the calcium levels in the blood.
Answer:
The correct answer is metaphase.
Explanation:
During metaphase, the lining up of the chromosomes takes place at the metaphase plate, under the influence of the mitotic spindle. In each of the chromosomes, the sister chromatids are held together with the help of microtubules from the contrary spindle poles.
In metaphase, the spindle has captivated all the chromosomes and aligned them in the center of the cell, which is ready to differentiate.
Answer:
second messenger cascade
Explanation:
Second messenger cascade is activated by the NE beta receptor which then activates the G protein. G protein in turn activates the enzyme responsible for converting ATP to cAMP i.e adenylyl cyclase. When the level of cAMP reaches a certain level, the enzyme protein kinase is released. The enzyme phospholipase is released as the G proteins get active and breaks down the phospholipid membrane into two secondary messenger molecule.
Properties of Life. All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
