"Dosterone" is correctly spelt as ALDOSTERONE.
Answer: The correct answer is option A) causes conservation of sodium
Explanation:
Aldosterone is chiefly concerned with the balance of salt and water in the body. Thus, it stimulates the reabsorbtion of sodium (Na+) ion from the kidney tubules and as such regulates NaCl contents of the blood.
So, Aldosterone causes conservation of sodium
Estuary ecosystems would be most affected because it is a mixture of salt and fresh water.
Answer:
The correct answer will be option-D
Explanation:
The cell cycle is the cyclically ordered sequence of events taking place in the cells associated with the division of the cell.
The cell cycle takes place in two phases: the interphase proceeded by M-Phase. The interphase of the cell cycle proceeds in G₁, S and G₂ phase. During the G₁ phase, the cell prepares itself to prepare for the next important phase marked by the synthesis or replication of the genetic component of the cell.
The changes that take place during the G₁ phase thus includes the increase in size and the production of ATP as DNA replication is an energy-dependent process.
Thus, Option-D is the correct answer.
Life is found almost everywhere on Earth, but it is not distributed evenly around the planet. Different species are found in different areas; some species have overlapping ranges, others do not. Each species has a set of environmental conditions within which it can best survive and reproduce. Not surprisingly, those conditions are the ones for which it is best adapted. Many different physical, abiotic (non- living) factors influence where species live, including temperature, humidity, soil chemistry, pH, salinity and oxygen levels.
