Answer: C) An increase in the carrying capacity of the ecosystem for wetland organisms.
Explanation:
The wetlands are the ecosystem that are developed when a water from any of the source like ocean, river, lakes, snow melting and rainfall get deposited in the shallow regions of the land. The water in such region may remain for either temporarily or seasonally.
According to the given situation, the process of restoration of wetlands will help in increasing the carrying capacity of the wetland ecosystem. This is because of the fact that the organisms which are capable to survive in wetland ecosystem may experience disturbance due to human interventions. But with the increase in area and supply of water from the river the carrying capacity of the ecosystem will increase. The carrying capacity is the number of members of the population of species which an ecosystem can allow to survive.
Kidney regulates the volume of blood in the body to maintain blood pressure.
Answer:
12 chromatids.
Explanation:
If a cell has 6 chromosomes in the G2 phase will have 12 sister chromatids during that same phase because replication of chromosomes occurs which produces two exact copies of each chromosomes. Then 6 chromatids are distributed in one daughter cell while the other 6 chromatids are distributed in other daughter cell and finally the cell division occurs.
I believe this process is known as Assimilation. In this process nutrients are absorbed into the body after digestion in the intestine and its transformation in biological tissues and fluids. Assimilation is different from absorption as absorption involves the process of moving food from the digestive system into the blood system for the transportation to all body parts, while assimilation is the uptake of nutrients into cells and tissues and consequent building up into mores complex substances.
