Answer:
spiders are. generally ectotherms.Their internal temperature depends on external temperature transfer.They are also poikilothermic because the body temperature varies with that of the external environment.,
In animals, individual cells are grouped into tissues. e,g Blood. The tissues gives rise to organs.
A main function of most types of epithelial tissue is covering surfaces.They line major all hollow surfaces, and covering body surfaces.
Resorption id the movement of fluid from the glomerular filtrate back into the blood. Ions, glucose,and other escaped metabolites are returned to the blood stream.
In humans, goosebumps are a vestige of a mammalian adaptation to thermoregulation. This is a thermoregulatory mechanism to regulate the body temperature,Goosebumps emits heat, to turn the moisture from the skin to vapour. This evaporate to release this moisture, which cools the body.
Explanation:
The blood has low oxygen content
Answer:
a. They would have a black chick? 25%

Answer: release of oxygen by green plants
Explanation:
Answer:
The changes in the population of a species in a stable ecosystem has diverse effects on the ecosystem on the whole.
The reduction in the baleen whale population will cause a rapid increase on the prey organisms on which the baleen whale fed. This is because the number of predators for these preys will decrease.
On the other hand, the number of organisms which fed on the baleen whale will decrease as they will have lesser amounts of food available.
