Answer:
Pleiotropy
Explanation:
Pleiotropy is a genetic condition in which a single gene conditions the expression of multiple phenotype. There are different types of pleiotropy depending on the underlining mechanism
- <em>gene pleiotropy</em>
- <em>developmental pleiotropy</em>
- <em>selectional pleiotropy</em>
- <em>antagonistic pleiotropy </em>
<em>Phenylketonuria is a disease characterized by increased level of amino acid phenylalanine in the blood. It caused by mutation to the gene responsible for breaking down phenylalanine in the blood. Elevated level of phenylalanine causes other issues such as mental problems, urine coloration and reduction in skin pigmentation. This is a clear case of pleiotropy.</em>
Answer: Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression occurs because of certain signals in your body, both inside and outside of your cells. Cell differentiation occurs during multiple stages of development.
Answer:
light is required to provide energy for photosynthesis
Explanation:
For photosynthesis to take place, it requires the presence of light and chlorophyll. The process has two stages; light and dark stage.
In the light stage, chlorophyll molecules absorb light energy which is used to split water molecules into oxygen and hydrogen atoms. The process is called photolysis.
water→ hydrogen atoms + oxygen.
The hydrogen atoms produced enter the dark stage while oxygen is released in the atmosphere. In the dark stage, carbon dioxide combines with the hydrogen atoms to form simple sugar such as glucose.
