Answer:
Explanation:
Stomata: as it allows the diffusion of carbon dioxide in the cell and oxygen out the cell.But it is held together by the guard cell.
Root hair cell:as this absorbs water and mineral ions efficently it does this by increasing surface area to absorb efficently and it ahs lots of mitochondria for the active transport of minerals ions from a dilute solution in the soil to a concentrated solution in the root hair
Xylem:This is spiral rings which are formed in a cell
The movement of the ocean's crust
Answer:
Taking antibacterial drugs for viral infections
Explanation
This is called a misuse of antibacterials also popular known as antibiotics. This results in an increased chance of bacteria developing mutations against the antibacterial hence rendering the drugs ineffective in treatment. They also form the risk of causing dangerous mutations that turn harmless bacteria into harmful bacteria.
Answer:
The correct answer would be - wildtype.
Explanation:
Let assume there are four genes which are :
A-B-C-D
In mutant first, the genotype would be:---a-b-C-D
In the mutant second, the genotype would be:--A-B-c-d
If both of these genotypes are crossed with each other, the recessive genes a, b of mutant first is dominated and masked the expression by the dominant genes present in the mutant second.
Similarly, the recessive genes of the mutant second are dominated and masked expression by the dominant genes of mutant first. This is possible only due to different genes are present in mutants.
Thus, the correct answer is - The correct answer would be - wildtype.
