Answer:
The correct answer is the endocrine system.
Explanation:
The sympathetic division of the autonomic nervous system and the endocrine system are the two prime systems that take part in the stress response.
At the time of acute or chronic stress, the endocrine system first makes the hypothalamus to discharge CRH or corticotropin-releasing hormone into the bloodstream. The release of CRH further makes the anterior pituitary to discharge ACTH or adrenocorticotropic hormone into the blood. This further stimulates the adrenal cortex to discharge cortisol, that is, one of the glucocorticoid hormone into the bloodstream.
The cortisol finally makes the organs and tissues present within the body to effectively cope up with the initial stress stimulus.
Answer:
Plants exchange two gases in the atmosphere i. e. oxygen and carbondioxide. Carbondioxide is entered into the plant body through small opening called stomata which are present on the surface of leaves. Carbondioxode is used as a raw material in the process of photosynthesis. Oxygen is produced in the end of photosynthesis process and releases in the atmosphere.

Answer:
The water vascular system of echinoderms (B) functions in locomotion and feeding.
Which of the following combinations of phylum and description is correct? (C) Platyhelminthes—flatworms, gastrovascular cavity, no body cavity
Explanation:
Echinoderms are marine animals. They have a water vascular system that make them able to move (locomation), respiration and food and waste transportation. This system is full of different canal along the body.
Echinodermata has not a radial symmetry as a larva, in fact it has a bilateral symmetry and coelom present. When it comes to Nematoda, they are roundworms and have a pseudocoelomate. Finally, porifera has a gastrovascular cavity and no coelom.
The answer is chromosomes. The chromosome contains the DNA nuclei. It contains all the genetic material of the parents.It is often duplicated in the cell metaphase of the cell division. Chromosomes differ from one organism to another. They are often visible under the microscope.
