<span>True. Plants are considered as organic materials. The process of bioremedation is a waste management technique where these organic materials are used to remove pollutants and neutralize sites that are contaminated with hazardous substances. Areas that are deemed toxic will be uncontaminated after this technique because the pollutants have been broken down by these organic substances. <span>

The right answer is Bleu.
Chlorophyll b is a yellow form of chlorophyll that essentially absorbs blue light and is more soluble in aqueous chlorophyll a because of its carbonyl group.
Chlorophyll b is not an initial electron donor in the respiratory chain but increases the energy efficiency of photosynthesis by increasing the amount of light energy absorbed by plants and other photosynthetic organisms.

Thus, the correct answer is option (C).
A scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. A scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.
Models are simplified representations of of different complex systems. They also help to study very small or large objects.
Option B, D and E.
Explanation:
Models are very simplified representations of complex systems and organs or structures which are prepared to study those systems by scientists and normal people easily. Many structures of human body like cells or some tissues are very small in structure or microscopic in nature. So studying them are very hard without specific instruments which are not always available. Thus models are made to easily study those structures by scientists and even normal people and students.
