<span>Although the light dependent reactions of photosynthesis are not affected by changes in temperature, the light independent reactions of photosynthesis are dependent on temperature. They are reactions catalysed by enzymes. As the enzymes approach their optimum temperatures the overall rate increases.</span>
Answer:
Yes
Explanation:
Amino acids create proteins
Ans.
Sickle-cell disorder shows defected red blood cells, due to mutation in gene that code for hemoglobin. The mutated genes for sickle-cell disease are found in higher percentage of sub-Saharan African population as it provides protection against malaria as compared to population of United States.
Malaria is common in sub-Saharan Africa region and there, natural selection favored gene for sickle cells, because it might be beneficial to people having sickle cell disease that makes them able to survive in such condition and transmit their genes to offspring.
On the other hand, in those Africans, who moved to United States, where malaria is uncommon or absent, natural selection favored normal, wild type genes, resulting in fewer people with defected sickle cell.
Thus, the evolutionary process behind this is 'natural selection.'
Answer:
A cell that makes steroid hormones
Explanation:
A cell that makes steroid hormones have the greatest concentration of smooth endoplasmic reticulum. It is named so because it is not studded with ribosomes on its surface unlike rough endoplasmic reticulum. It has smooth appearance. Its main function are synthesizing lipids, carbohydrates, steroid hormone and detoxification.
