A gorilla and a human. 98% of our genes are identical to those of a gorilla.
I thinks its a layer of soil with characteristic properties, sorry if its wrong I'm a beginner
The third one is correct. Mitosis creates two identical cells. Meiosis creates four different cells.
Choice C is correct.
WHY: In meiosis, sex cells (eggs or sperm) are produced. This means that they must have <u>half </u>the number of chromosomes in each, and they must be each <u>UNIQUE</u>.
Thus, the other options (A,B,D) cannot be correct because the product of meiosis cannot be the exact copy of the parent cells, and so cannot have the same number of chromosomes either.
Answer: By Hormonal action and Nervous coordination
Explanation:
Hormones are substances produced by one tissue and conveyed by the bloodstream to another to effect physiological activity. Homeostasis is the maintenance of a stable internal environment in the body.
Body systems such as digestive, circulatory, excretory systems etc, all are coordinated to achieve a STABLE INTERNAL ENVIRONMENT by the aid of HORMONES AND/OR NERVOUS COORDINATION.
For Example: the vasodilation of blood vessels during hot weather, and the opposite action of vasoconstriction during cold weather are both controlled by Hormonal action and nervous coordination which leads to a stable body temperature preventing excess heat accumulation.
Also, Nervous system controls the body systems, such that the muscle contractions are joined to actions like sweating, breathing, respiration etc
So, to maintain homeostasis hormonal action and Nervous coordination is necessary.
