The response of the body's homeostatic control systems to large increases in muscle O₂ requirements during heavy exercise is the increase in body's pulmonary ventilation.
Homeostasis is the state of balanced internal system of the body. A homeostatic body does gets affected by the outer environment as it adjusts itself accordingly. The state of homeostasis can be in terms of thermoregulation, blood glucose regulation, osmoregulation, etc.
Pulmonary ventilation is the process of inhalation and exhalation of air. This is done to fulfil the demand of oxygen in the body and also to remove the waste carbon dioxide from the body. Pulmonary ventilation in simple terms is breathing.

They have a nucleus, are multicellular, and include animals and plants.
Answer:
Explanation:
The chromosome separation process ensures that each sex cell has a unique combination of genes in its nucleus. Fertilisation is also a random process and so when the nuclei fuse the resulting fertilised egg (zygote) has an individual genetic makeup.
Answer:
Diffusion
Explanation:
Movement, cell division and active transport ( Transport of material such as magnesium in plant from the region of lower concentration to the region higher concentration through the use of ATP) all need ATP for the processes to occur so they will be affected but diffusion ( movement of particles from the region of higher concentration to the region of lower concentration until they are evenly distributed ) is a process that does need ATP to occur and therefore will be least affected.
