Answer:
C
Explanation:
The DNA in all the cells of an organism are the same. The reason there are different types of cells in the organism even through their DNA is the same is because genes are deferentially expressed in the cell types. The genes that are expressed in the brain cells are different from those expressed in the liver. The rest of the genes that are not being expressed are silenced through folding by histones – so they are not exposed to DNA polymerase.
Answer:as the blood travel through the tissue , it pick up waste produced by the body cell
Explanation:
Sediment. So the river picks up sediment when it is moving quickly and deposits it when it slows down (or when there is a bend in the river).
Answer:True
Explanation:
Mitosis is just a part of a cell cycle. Mitotic M phase include both mitosis and cytokinesis.
In the cell cycle Mitotic cell division alternate with Interphase a growth phase. In the mitotic phase, mitosis divides the cell nucleus and distribute it's chromosomes to the daughter nuclei, cytokinesis divides the cytoplasm, producing two daughter cells.
During mitosis in the telophase stage of mitosis the division of one nucleus into two genetically identical nuclei, is completed.
In Cytokinesis, the division of the cytoplasm is usually well under way by the late telophase, so the two daughter cells appear shortly after the end of mitosis
Answer:
Explanation:
The genetic determination of coat colors in calico cats is linked to the X chromosome wherein calicos are nearly always female, with one coat color allele linked to the maternal X chromosome and a second coat color allele linked to the paternal X chromosome.
Since, the females possess two X chromosomes (XX), they can be either homozygous for each coat colour or be heterozygote (calico). But in the males, since this trait is X- linked and males have just the one X chromosome (XY), they can only possess either of the coat colour and not be an heterozygote. But an XXY male cat can be a calico due to the presence of the two X chromosomes.
