Answer:
B
Explanation:
This may be rong, however I think this needs to happen before the mRNA can leave the nucleus. The cap helps prevent the mRNA from being destroyed by the cell itself once it leaves the nucleus.
Answer:
Interactions such as picking and blowing dandelions before they have became a flower helps to spread their seeds and letting more of them germinate. In another context, talking to flowers in general help because when you breathe out Carbon Dioxide, flowers and plants absorb it as it is what they need to grow.
Answer:
ability to differentiate into other cell types during cell division i.e. totipotent nature
Explanation:
Stem cells are undifferentiated cells with the unique ability to develop into specialized cell types in the body during early life and growth through the process of cellular differentiation. When a stem cell divides, each new cell has the potential to either to remain a stem cell or become another type of cell with a more specialized function e.g muscle cell, red blood cell or a brain cell.
Stem cells provide new cells for the body as it grows, and replace specialized cells that are damaged or lost. This ability of stem cells to differentiate into a variety of cell types in an organism including embryonic tissue, is an important distinguishing factor. They have two unique properties that enable them do so:
1. They can divide over and over to produce new cells
2. As they divide, they can change into the other types of cell (cellular differentiation).
Answer:
It is a very good discussion debate, although I believe that the most effective way to generate the actin head to generate such a displacement requires a good full energy currency, which is considered much better by ATP.
Regarding the information sought in 1950 (Straub), he was publishing that he could bind ATP and that during the polymerization of the protein to form microfilaments, it hydrolyzed to ADP + Pi, which remained bound to the microfilament.
Straub suggested that this reaction played a role in muscle contraction, but this is only true for smooth muscle and was not verified experimentally until 2001.
At the point where it is stated that ADP + Pi is necessary for the formation of polymers, it is extremely true and a very good posture.
What we can highlight as false in all this argument is that for muscle contraction ATP is not needed, since for it to occur if or if there must be ATP or energy currency.
Explanation:
Then we can conclude that both statements are valid with the difference that in the case of ADP + Pi it requires more evidence.
