It is during anaphase that centrioles begin to move to opposite poles as they are pulled back by the spindle fibers
Answer:
Yes.
Explanation:
A virus is a dangerous cell. And cells are alive. The nucleus in the cell gives it it's "life" by controlling what the cell does at all times. The nucleus is like our brain or heart, you could say,
Answer:
It will swell and eventually burst because water from the environment is flowing into the cell
Explanation:
This question is describing OSMOSIS, which is the movement of water from a region of high concentration to a region of low concentration across a semi-permeable membrane. The osmotic process is facilitated by the formation of an OSMOTIC GRADIENT i.e. difference in concentration between the two sides of the membrane.
In this case, an animal cell containing an internal salt concentration of 70% (hypertonic) were placed in a salt solution with a concentration of 20% (hypotonic), OSMOSIS will occur in the sense that water will move from where it is more concentrated (salt solution) into where it is less concentrated (animal cell), hence, the animal cell will SWELL AND EVENTUALLY BURST.
The principal advantage of asexual reproduction is that the organism does not have to waste time or energy looking for a mate.
Answer:
Probably A.
Explanation:
The reticular formation can be said to be a network of nuclei in the brainstem that wakes or alert us to a sharp reaction or occurence at a particular time.
