Answer:
These creatures depend on the sea water for nutrients, protection and to move about. At low tide,many of these creatures are exposed to the air, leaving them at risk of predator attacks andoxygen depletion. The whole eco-system of the tide pools would simply not exist without theconstant movement of the tides
Explanation:
Answer:
A single round of DNA replication occurs in the parent cell, followed by two distinct nuclear division cycles. The process produces four haploid daughter cells, each with half as many chromosomes as the diploid parent cell.
Explanation:
During sexual reproduction, meiosis produces the sex cells that combine to make new children.
Meiosis is a type of cell division that results in the formation of sex cells (egg and sperm). And that is brought together to generate new progeny through the act of sexual reproduction.
Meiosis generally results in 4 haploid daughter cells, meaning half no chromosomes are contained in diploid cells.
I not sure but i think it is 4
Answer:
Maybe B, I need more evidence
Explanation:
Answer: When genes found on different chromosomes, said to be not linked.
When genes seen close together on the same chromosomes said to be linked.
Explanation:
(a)
According to Mendel’s law of independent assortment, when genes located more than 50 map units and found on different chromosomes as far apart on the same chromosome so they divide independently and obviously said as not linked.
(b)
It is found that when genes located and seen tightly close together on the same chromosome, known to called as Linked which means that alleles or genes look close together on the same chromosome can be inherited afterwards as a unit frequently than not. For instance, when two genes are linked and become tightly close together by using data from genetic crosses lead to calculate recombination frequency as well.
Similarly, when we finding recombination frequencies for more than one gene pairs, can make linkage maps among them that finally show the relative distance between them.
