Answer:
Explanation:
1 Long term exposure to harmful genotoxic chemicals or ionizing radiation can cause changes in the base sequence of DNA.Chemicals might induce DNA mutations, such as polycyclic hydrocarbons (fumes found in oil stations, or smoke from a tobacco cigarette), intercalating agents such as Ethidium Bromide (carcinogen), but also radiations such as UV-radiation (C and T bases are most vulnerable and would bind to identical bases unstead of their
2 Genetic changes that are described as de novo (new) mutations can be either hereditary or somatic. In some cases, the mutation occurs in a person’s egg or sperm cell but is not present in any of the person’s other cells. In other cases, the mutation occurs in the fertilized egg shortly after the egg and sperm cells unite. (It is often impossible to tell exactly when a de novo mutation happened.) As the fertilized egg divides, each resulting cell in the growing embryo will have the mutation. De novo mutations may explain genetic disorders in which an affected child has a mutation in every cell in the body but the parents do not, and there is no family history of the disorder.
Somatic mutations that happen in a single cell early in embryonic development can lead to a situation called mosaicism. These genetic changes are not present in a parent’s egg or sperm cells, or in the fertilized egg, but happen a bit later when the embryo includes several cells. As all the cells divide during growth and development, cells that arise from the cell with the altered gene will have the mutation, while other cells will not. Depending on the mutation and how many cells are affected, mosaicism may or may not cause health problems.
<span>Alpine Biome, although found on the five of the seven continents of the world, is not the largest biome in the world. It has only two distinct seasons,not four and is characterized by the presence of coniferous trees (the first indicator that you are about to enter an alpine biome) mosses, and even wild flowers too . It is not just located in mountain regions but it in great and wide mountain ranges of the world. --The answer to this question then is not letter C but letter B.</span><span />
Hey!
The water cycle is driven by solar energy, see solar energy is what makes water evaporate, which needs to happen for precipitation to happen, and precipitation reaches earth in hail, snow, or rain which will run-off into oceans and evaporate or just eventually evaporate.
So, yes, solar.
