lozanna [386]
Plants inherit genes that enable them to produce chlorophyll, but this pigment is not produced unless the plants are exposed to light. this is an example of how the environment can influence on gene expression.  
<span>
Light has an important role in gene expression in plants by producing a number of light-induced changes. One of the examples of the light effects is that chlorophyll and the proteins required for assembling the photosynthetic apparatus are synthesized together with the enzymes needed for carbon fixation. Gene expression influenced by light includes the regulation at the level of transcription or, alternatively regulation of translation.</span>

viva [34]

Answer:

c. none of the subjects to show signs and symptoms of a cholesterol deficiency during the entire study.

Explanation:

this is because the blood cholesterol is from two sources. Nearly 80% of the cholesterol the body needs  are made by the liver and intestine.certain small amounts are also produced in the adrenal glands and the reproductive organs.The remaining fragment amounts comes from the diets.

Therefore even if these subjects  were fed with diet without cholesterol, it will not have any significant effects on the body cholesterol composition. Therefore no symptoms of its deficiency will be observed.

Generally it biosynthesis is regulated by the amount of cholesterol present in the blood.

In-s [12.5K]

Answer: etiolation of plant growth in shade, with fast growing cell without chloroplasts. Out of shade, cell differentiate again to produce photosynthesising cells

Explanation: It is a subjective decision as to what is ‘best’. Good examples are plant responses to changes in the nutrient supply.

when soil nitrogen is depleted some plants, such as legumes, grow nodules on their roots, with cells that release chemical signals to attract nitogen fixing bacteria.

Lack of light induces etiolation in many plants. New cells elongate and develop without chloroplasts, with rapid cell division exhibiting gravitropism, extending upward. When they grow beyond the shade area, cell differentiation changes again, to produce photosynthesising cells.
