Answer:
It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions.
Explanation:
Answer:
Option A
Explanation:
The carrying capacity of any given ecosystem is the maximum production that is achieved without environmental degradation. Now, since the production in option B and C is less than 500,000 tons (i.e carrying capacity of Grand Banks of Newfoundland), thus the rate of population growth would not be greatest and hence both option B and C are incorrect
Option D is also incorrect as production cannot be greater than carrying capacity or else environment will start degrading
Hence, option A is correct
D. Thigmotropism. A "tropism" is a plant movement in response to an environmental stimulus, and "tropo" means "touch." Plant cells change their movements when they detect a change in pressure after having contacted something. It is not A because germination is the sprouting of seedlings. It is not B because photosynthesis is the action of plants to convert light energy into chemical energy. It is not C because phototropism refers to movement in response to a change in light ("photo" means "light").
