In the cells with nucleus, as in eukaryotes, the cell cycle is also divided into three periods which are: Interphase- the mitotic (M) phase, and cytokinesis. During interphase the cell growth accumulating nutrients needed for mitosis preparing it for cell division and duplicating its DNA
Answer:
there are two types of cell one eukaryotic cell that have true nucleus (genetic material enclosed in membrane) and membrane bounded organelles and other is prokaryotic cell that donot have have true nucleus (genetic material dispersed in cytoplasm) and membrane bounded organelles.
similarities between PC and EC is that both contains cell membrane, ribosomes (not a membrane bounded organelle) .
examples of PC are bacteria , paramecium,fungi etc
examples of EC are plant and animal cells
there are two names for cell membrane i.e plasmalemma, cell surface membrane,
selectively permeable or semipermeable means cell only allows those material to pass through its cell membrane which it needs.this cell'ability is important because to protection against the poisonous substance and to maintain cell needs .
The question is incomplete as it does not have the option which are:
- primates A and B are more closely related to each other than either is to primate C.
- all three primates appeared on Earth at about the same time.
- either primate A or primate B must be a direct ancestor of primate C.
- primate C must have been the ancestor of both primate A and primate B.
Answer:
Primates A and B are more closely related to each other than either is to primate C.
Explanation:
In the given question, on the basis of the given information, it can be predicted that the Primate A and B are more closely related to C as the DNA sequences of these two primates are almost similar. The similarity of the sequence suggests that these primates have descended or diverged from a common ancestor.
The DNA sequence of C is different from both A and B which shows that both A and B are different from the C.
Thus, the selected option is the correct answer.
