Answer:
Genetic variation among plant populations often occurs along different climatic gradients, such as temperature and precipitation gradients.
Environmental factors are often responsible for the patterns of genetic structure observed at small spatial scales (Sacks, Brown, & Ernest, 2004).
The soleus muscle is mainly used for pushing off the ground while walking. It is important for activities such as walking and running. This muscle also helps in maintaining a person’s posture by preventing the person from falling forward. Thus, this muscle is more often used by marathon runners.
<span>Transport of the water from the roots to the leaves is driven through the vascular tissue called xylem. Water gets absorbed from the soil by osmosis and it must cross several cell layers (filtration system) before entering the xylem. The method used in the upward movement of water through the xylem is determined by the cohesion-tension theory (capilarity+transpiration). The transport is passive and it occures thanks to the primary force that creates the capillary action (adhesion between the water and the surface of the xylem and cohesion between individual water molecules) movement of water. Transpiration is also an important factor in the upward water movement. Transpiration in leaves creates tension (differential pressure) and because of this tension, water is being pulled up from the roots into the leaves.</span>
