Answer:
Water is sucked up xylem by mass flow (cohesion-tension) which decreases the water potential in the root xylem. So water diffuses through the root cells to the xylem which decreases the water potential in the root epidermis cells, so water diffuses into root hair cells from soil by osmosis.
Explanation:
Often, waterfalls form as streams flow from soft rock to hard rock. This happens both laterally (as a stream flows across the earth) and vertically (as the stream drops in a waterfall). In both cases, the soft rock erodes, leaving a hard ledge over which the stream falls
Carrying capacity is the paramount number of a particular species that the earth or ecosystem can hold while limiting factors are the biotic and abiotic factors that confines or limits the growth of the living organism.
More the amount of limiting factor, greater will be the number of growth of the organism as the raw materials to hold life would be enough to sustain these many number of organism. Therefore, limiting factor governs the carrying capacity of various organisms on earth.
Answer:
C. Hypothalamus
Explanation:
Also known as the "thirst center", the hypothalamus controls the autonomic functions like hunger. It regulates temperature and it also holds the "master gland" or otherwise known as the pituitary gland. The pituitary gland controls the functions of the other endocrine glands.
The best answer would be the hypothalamus.
The prevalence rate of a disease refers to the number of people in a population that are affected by a particular disease. The only two reasons why the number of this set of people will decrease is if a cure is found for the disease or if those affected are dying.
Cure or death will reduce the prevalence rate.<span />
