Answer:
Bacteria that entered an organism body can cause mutations by altering the gene
C i think . Hope this helps
Myelin sheaths are found on the outside of nerve cells. They protect the sensitive axons underneath like how insulation protects wires.
Answer:
2. The white patches are caused by the deacetylation of the histones associated with the DNA of the w + allele.
3. The red patches are caused by the acetylation of the histones associated with the DNA of the w + allele.
Explanation:
The complete question is as follows:
How might one explain position-effect variegation in terms ofhistone acetylation and/or deacetylation? Select all thatapply.
1. The white patches are caused by the acetylation of the histonesassociated with the DNA of the w + allele.
2. The white patches are caused by the deacetylation of thehistones associated with the DNA of the w + allele.
3. The red patches are caused by the acetylation of the histonesassociated with the DNA of the w + allele.
4. The red patches are caused by the deacetylation of the histonesassociated with the DNA of the w + allele.
In the W+/W State variegated eye is produced, however in reality the W+ allele causes a red eye colour whereas the W allele causes a white eye.
The reason for production of variegated eyes is chromosomal rearrangement.
Due to the chromosomal rearrangement the W+ gene's position gets changed and it moves from a region of euchromatin to heterochromatin and this position affect leads to red and white patches in the eye.
The heterochromatin is silent region of the genome which does not encode for any product and this is caused by histone deacetylation whereas the histone acetylation makes the chromosomes more accessible and contributes the euchromatin region.
Reduce!<span> Buy and use less stuff. This is the best way to conserve natural resources. For example, it takes one ton of raw materials from the earth to make one laptop computer! We can also pay special attention to reducing the amount of non-renewable resources we use. For instance, by reducing our use of non-renewable oil and coal to give us energy and electricity, we can make less air pollution. Instead, we can get energy from the sun, the wind and the ocean's tides to heat our homes and light our rooms. These sources of renewable energy don't create pollution and they will never run out! We can also look for different natural resources to use so that we don't use up too much of one kind. For example, we can make tree-free paper out of plants like kenaf, bamboo, and hemp instead of trees! Using tree-free paper is much better for our forests and all the animals that depend on a healthy forest in order to survive.</span>
