The answer would be A
explanation: I learned this lol
Interesting biology question.
In order to answer this question, I hope you understand what is mitosis: cell division that creates two diploid "daughter" cells that are identical to each other. Gametes, remember, are the reproductive cells (egg cells and sperm).
If human gametes were made by mitosis, which is not true, because gametes are made in meiosis, they would simply be diploid with somatic cells. The two gametes would have 92 chromosomes, as each cell has 46 chromosomes. And after each generation, the number of chromosomes would keep doubling, which would be very weird. Remember that the normal amount of chromosomes that a human being has, is 46. Maybe humans would have mutations if that happened.
Answer:
Explanation: They are not producers because they do not make their own food from the sun, the organisms that can make their own food from the sun are called or can be called autotrophs. The rabbits, Lions, Bears, etc, are heterotrophs
Answer:
Estrus Synchronization
Explanation:
This is the procedure of manipulating the reproductive hormones of the female animals so that, the heat period occurs at relatively the same time that is convenient and preferred by the producer. This is for timed ovulation needed for techniques of artificial insemination for artificial selection. Thus the producer is able to plan his insemination programme to suite his work engagements.
The common hormones for this procedure are; Prostaglandins F2α :<u>(which suppresses the oestrous cycle, to end, and restart the entire cycle and ovualtion again to suit the producer</u>). Progestins: (<u>which inhibit heat and ovulation until it is removed by the producer</u>) and also induces oestrous cycle in a non oestrous animals,and Gonadotropin Releasing Hormone.( for inducing oestrous cycle in non oestrous animals, and for stimulating eggs production when needed.
Its advantages includes
uniformity in kids rearing,
uniformity in slaughtering period,
availability of milk round the clock,
control of transmission of infectious diseases.
