I believe the correct answer is A. Increases the rate of a chemical reaction. This is because they act as catalysts.
It Is The Melanoma Gene .
The correct answer is option C. A leaf growing in full sunlight
The chloroplast is an organelle, which helps the plants to carry out the process of the photosynthesis. The leaves are the main site of the photosynthesis in the plants, hence, they have an abundant number of chloroplasts present in the cells. In the presence of the sunlight, they perform the light dependent reactions of the photosynthesis process. In case, a scientist find out the cell, which have a high number of chloroplast, then the cell must be specialised to perform photosynthesis, hence, the cell would belong to the leaves, which are growing in full sunlight.
Answer:
they need to be able to maintain their salt content, thru osmoregulation
It is d, a substance that participates in a chemical reaction. You can also tell it just by looking at the stem of the term :)
