Answer:
John Stephen Jones states that in evolution it is necessary to have into account three factors: natural selection, mutation, and random variation.
Explanation:
These three mechanisms influence evolution and they are responsible for generating phenotypic diversity that is observed in humans.
I recommend to read his article (chapter book):
Jones, JS. (2012). Is Human Evolution Over?. In Evolution 2.0 (pp. 167-176). Springer, Berlin, Heidelberg.

Answer:
cell transport or membrane transport helps in the transport of solute molecules and ion across the plasma membrane and helps in maintaining homeostasis of these molecules in the biological system.
Explanation:
Homeostasis is very very important to maintain a steady body physiology and the maintenance of steady body physiology is highly significant because any type of disturbance in the homeostasis can leads various physiological abnormalities.
Various membrane transport process such as osmosis helps in the movement of water from high concentration region to the region of low water concentration until equilibrium is reached.Thus osmosis helps to maintain water homeostasis in our body.
By the same way glucose transporter maintain the homeostasis of glucose inside our body.
Potential evapotranspiration is higher in the summer, on less cloudy days, and closer to the equator, because of the higher levels of solar radiation that provides the energy for evaporation. Evapotranspiration is the sum of evaporation and plant transpiration from the Earth's land and ocean surface to the atmosphere. Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and water bodies. Transpiration accounts for the movement of water within a plant and the subsequent loss of water as vapor through stomata in its leaves.
