Answer:
At the end of<u> telophase II </u>and cytokinesis, there are four haploid cells.cells.
Explanation:
During telophase II the sister chromosomes separate from each other and move to the opposite ends of the cell. Once that the chromosomes are in the opposite ends, the cytokinesis starts, this is the division of the cytoplasm that will give two daughter haploid cells.
We have to remember that there will be four haploid cells because there are two cells, which are the result of meiosis I, that will go into meiosis II to give these four daughters haploid cells. Also, the phases in meiosis I and II are very similar. Both of them have prophase, metaphase, anaphase, and telophase.
Answer:
The homozygous dominant phenotype is higher than expected, indicating that evolution has occurred.
Explanation:
At the start there are 200 fishes in the pond, 100 of them are AA(50%) and 100 of them are aa(50%). Using the Hardy-Weinberg Equilibrium equation we can say that the gene frequency is
A=0.5
a=0.5
With those frequency, the expected percentage of offspring with dominant genotype will be:
AA= 0.5 * 0.5 = 0.25 = 25%
The number of homozygous dominant found is 35% which is higher than expected (25%). Higher homozygous dominant frequency than expected means the Hardy-Weinberg Equilibrium is changed. In this case, evolution probably the cause that shifts the gene frequency.
The correct answer is <u /><em>a</em><em>daption</em>. The particular environment in which a particular environment is exposed to gives it the characteristic or the ability to adapt. This is how a particular ecosystem works. It is the relationship of organisms within their environment that evolves through time in order for it to survive and propagate into more adapted kinds of species.
Happy to help!
Answer:
The anerobic part takes place in the fluid part of the cytoplasm while the aerobic part takes place in the mitochondria
Explanation:
Answer:
The amphipathic property of the phospholipids that constitute the membrane
Explanation:
It seems like a options-based answer so it would be better if they were included here but basically, each of those phospholipid molecules has two parts with antagonistic reactions towards water.
The head is polar or hydrophilic, wich means it can be sorrounded by water. The tail, is apolar or hydrophobic which means it is repelled by water.
The interior and exterior of the cell is contain water-based substances, that's why the heads of the phospholipids are oriented like that with the tails protected inside the membrane.
This double layer structure has a fundamental role in the fluid property of the cell membrane from which derive most of it's functions.
