The answer is letter A. substitution of 3rd N-base to go
from AUU to AUC. Substitution mutations are a type of mutation in which a
single nucleotide is substituted with a different nucleotide. There are many
different ways that DNA can be changed, resulting in different types of
mutation; this are the type of mutations Substitution, Insertion, Deletion, Frameshift.
The 3 is vaporization and solidification
4 is vaporization
5 is solidification
A. Natural Selection. This is because the weeds that are not resistant to it die out before they can reproduce, but the resistant ones grow to maturity and then reproduce, passing down the resistance gene. Over time, the resistance gene would become a normal thing in weeds, while the non-resistant gene would not exist anyone, since the gene could not be passed on.
Answer:
<h2>
A
</h2>
Explanation:
1. A channel between two adjacent cells in known as an intercellular cleft.
2. And through these channels many molecules can easily pass between cells.
3. Importance of Intercellular clefts:
i) It is very important in transportation of fluids and small solutes.
ii) It contains gap junctions, tight junctions, desmosomes, and adheren proteins and these junctions help in regulate cell communication by signal transduction, surface receptors, or a chemogradient.
Can you add the picture or describe it to me? Right now I'd guess that it's probably bacteria because bacteria breaks it down into ammonium and nitrate, which is taken up by the plants by a process of nitrogen fixation. So, D.
