What is parthenogenesis? give an example

Biology
1 answer:
ANEK [815]3 years ago
3 0

Answer:

It's a form of asexual reproduction!

Development of the offspring happens without fertilization in this type of reproduction.

The two main ways in which parthenogenesis happens is by apomixis or automixis. Through apomixis , the egg cells are produced by mitosis. Through In automixis, egg cells are produced by meiosis.

Mitosis = a part of cell cycle: replicated chromosomes are separated into 2 nuclei

Meiosis = type of cell division that reduces the chromosome number by half. So now there is four haploid cells that are  genetically distinct from their parent cell.

Example:

An example of an animal that can use this reproduction is a bonnethead shark! Once a shark had a baby in a tank that only had three females!

(read about that on wikipedia)

Which of the following statements is FALSE regarding water intake and output by the body?
REY [17]

Answer:

The correct option is this: AN INCREASE IN FLUID TAKEN BY MOUTH WOULD REDUCE THE AMOUNT PRODUCED BY METABOLISM.

Explanation:

Generally, the amount of water consumed by a person normally leads to increase in the amount of urine that the person will excrete, that is, the higher the quantity of water consumed, the higher the quantity of the urine that will be excreted under normal circumstances. Thus, the statement given in option B is false. The statements given in Option C and D are right; during exercise the quantity of sweat produce and lost by the body is higher than the one that is produced when one is not exercising. Also, diarrhea usually lead to loss of water from the body.
