There should not be any changes in the gene pool.
In Hardy-Weinberg equilibrium, the gene pool should have a constant rate. The equilibrium can be achieved if there is no factor that favors one gene more than the others. Since the genes have the equal chance to survive and mating, the ratio of the gene pool should not change dramatically.
This description is unspecific and is confusing...
The nose has different functions mainly for inhalation of oxygen and exhalation of carbon dioxide which is called the respiration process or gas exchange. As a sensory organ, the nose has also another function which is olfaction, the ability to smell.
Olfaction in a biopsychological term, is the process by which sensory information recognized by the nasal receptors are transduced in a understandable and recognizable stimulus or rather perception, in simplest term is to smell.
Therefore, nasal receptors are the structures that send messages to the facial nerve which is responsible for sending the information to the brain for it to be perceived and acknowledge.
Answer:
CLOSED.
Explanation:
Stomata are found in epidermal layers in green aerial parts of plants, especially leaves. They occur mainly on the lower surface of dicotyledonous leaves, although on monocotyledonous, they are found on both surfaces. Intercellular air spaces found throughout the leaf are linked to stomata.
Stomata permits plant uptake of carbon dioxide, which is a necessity for photosynthetic processes. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration.
Therefore, it can be said that Stomata adjust temperature, staying closed when temperatures are hot and dry.
Answer:
I believe it must pass through 4 chambers
Explanation:
Eugenics is the science of improving a population by controlled breeding to increase the occurrence of desirable heritable characteristics. The term eugenics was coined by British explorer and Charles’ Darwin’s’ cousin Francis Galton in 1882, who is influenced by his cousins theory of natural selection. It comes from the Greek roots eu- means"good" and genos means "birth." It is known effort to improve the genetic makeup of a population. Galton believed that the human race could be improved by encouraging people who have "good" genes to marry early and have lots of children, and discouraging people with "bad" genes from procreating at all.
