Answer:
A.
Explanation:
Phototropism is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light have a chemical called auxin that reacts when phototropism occurs.
Pyramid biomass
<span>Pyramid biomass shows how energy are passed at
each tropics level and it is a graphical representation that shows the extents of
biomass per unit area at different tropic level with an ecological system. Also,
biomass is the food available for the next tropic level in a food chain and
they can be used as a source of renewable energy. </span>
Answer:
The correct answer is: A. Only the best-adapted animals in a population survive.
Explanation:
- Natural Selection is the process by which the individuals of a species which has the potential to sustain and survive in adverse or changing environment gets a survival advantage over those individuals which are unable to adapt themselves to altered environmental conditions.
- As the less potent individuals die in altered environmental conditions the adaptable individuals escapes competition with them for natural resources.
- Evolution causes species to alter their characteristics depending upon the demand of the conditions. These changes can vary, can be less or drastic.
- Animals pass all the newly adapted traits to the successive generations either as genetic traits or as acquired traits, as this is necessary for the offspring to survive in the altered environment.
- Natural selection is best defined as "the survival of the fittest".
Answer:
A) ADH secretion decreases. B) Urine osmolarity decreases.
Explanation:
Antidiuretic Hormone or ADH is responsible for the reabsorption of water through the kidneys.
A) Drinking alcoholic and/or caffeinated beverages decreases the release and effect of ADH so the water does not get absorbed as much as it should, which in turn results in more urination.
B) Osmolarity is a term used to express the concentration of a solution in terms of a certain particle. Since less ADH secretion results in more water being in the urine, this lowers the concentration of the urine. So urine osmolarity would be decreased.
I hope this answer helps.
