The human body comprises of more than 600 muscles differentiated in three classifications, and all are under the control of the nervous system. The activities like picking up a dropped pen or leaning over incorporate the combined effort of various muscle groups.
The alert mind relays this instruction to the central nervous system that conducts it in the form of electrical impulses. These are then mediated via the somatic segment of the peripheral nervous system to the nerves accountable for monitoring the essential muscles.
When the signals arrive, a chemical known as acetylcholine gets discharged from the nerve terminals, activating the membranes of muscle fibers and making them to contract. The receptors present in the muscles provide the brain with the instruction regarding the movement and position of the body, the brain monitors the contraction of skeletal muscles.
1.why is it important for gametes to be haploid?
They fuse to form a diploid organism so there is a correct number of chromosomes
2. The inheritance pattern of one gene will not affect the inheritance pattern of another gene. This is known as
independent assortment
3. which of the following is a difference between phase I and phase II of meiosis?
Phase I results in two diploid daughter cells ans phase II results in four diploid daughter cells
4. what is heredity?
The passing of genetic information from parents to their offspring
5. during meiosis sister chromatids may exchange sections of DNA leading to genetic diversity what is this process called?
crossing-over
TOOK TEST
Because it needs oxygen and can get it from blood also it can harm other cells by taking the oxygen away killing them. That is my best guess hope this helps pls mark brainliest if so please
A it determines how much of the surroundings an organism can see. Think about when you were younger, because you were shorter you could not see as much as you can now. you always had to stand on your tiptoes to see what was on the table or the counter.
