Answer:
c. the gravitational forces due to the sun and the moon cancel each other's effect
Explanation:
The two diagrams represent Neap tides. Neap tides occur when the Sun, the Moon and the Earth are aligned at right angles. Moderate tides are formed because the bulge due to gravitational pull of the Sun cancels the bulge due to moon. The difference between the high tides and the low tides is the smallest.
Answer:
Option (2).
Explanation:
Cell division is the process by which cell increases its number with the help proteins and enzymes. The four main phases of the cell cycle are G1 , S, G2 and M phase.
The cell cycle sequence is important for the proper division of the cell. Any change in these sequences might result in cancer and other disease. The skipping or change of any stage might cause the lack of material. The cell will lose the energy to divide or may result in uncontrolled cell division.
Thus, the correct answer is option (2).
Answer:
In areas of Africa where malaria is prevalent the number of sickle cell cases remains consistent generation after generation. ---- support the hypothesis.
In Canada the incident of sickle cell anemia has been increasing in the population. ----- contradicts the hypothesis.
Explanation:
In areas of Africa where malaria is widespread the number of sickle cell cases remains consistent generation after generation while on the other hand, In Canada the incident of sickle cell anemia are lower in the population because of environmental condition is not good for increase in malarial disease. In Africa, the environment is suitable for the mosquitoes that causes malaria so there is high increase of sickle cell anemia in the population.
Organisms get the energy they need from food just like us humans do.
They lose their visibility during telophase and are not visible during cytokinesis, which follows mitosis...
