Answer:
D
Explanation:
This is because one of its orbital shells is not filled – the one with 1 electron. This atom will, therefore, want to lose this electron – it takes less energy to do this than gain 7 electrons -- to achieve stable electron configuration. This makes this atom very reactive in a chemical reaction. Usually orbital shells of atoms begin with an S orbital shell that is filled with 2 electrons then P (x,y,z) orbital shells filled with 6 electrons total. There are also higher energy f and d orbitals that each take a maximum 10 and 14 electrons respectively. An atom is stable if its orbitals are fully filled.
Answer:
<u>Polygenic therapies are more likely to show </u><u>unintended effects</u><u> in other regions of the genome likely resulting in harmful diseases.</u>
<u />
Explanation:
Gene therapy involves biotechnological techniques that add or remove gene sequences in the genome. These are typically used in eliminating harmful genes that cause genetic diseases or disorders and are generally thought to improve an individual's quality of life.
Polygenic traits are controlled by several genes. Similarly, polygenic diseases may be caused by variations in several gene sequences. These include hypertension, heart disease, and diabetes. Polygenic therapies are more likely to show unintended effects in other regions of the genome, leading to other deleterious disease-causing effects.
C) Endocytosis is the answer for this question because a cell will go out and find something it needs and then take it in. (i.e. cell eating or phagocytosis)
Answer:
Presence of acidic oxides and other chemicals in air can change the PH value of the Rain.
Explanation:
Generally, PH value of rain remains 5.0. But when the air composition changes due to sulfur dioxide or nitrogen oxides released from automobiles and coal based power plants, the combination of these with rain water makes rainy water more acidic. This results in change of PH value of Rain.
