Brodt and Zimbardo found that shy women who were bombarded with loud noise and told that it would leave them with a pounding heart were subsequently no longer so shy when interacting with a handsome male.
a) with a pounding heart; no longer so shy
<u>Explanation:</u>
Shy is an emotion expressing nervousness, being reserved and timidity when communicating or being with some people. Shyness is generally observed in the person who has low self-confidence and inferiority complex.
Brodt and Zimbardo found that when a woman is continuously allowed to face loud noise, initially it may lead to pounding heart and subsequently they get used to it and they will be no longer shy. These scientists also found that when woman is interacting with the handsome male they will never feel shy.
Riparian zones are important to the natural environment because they function as natural biofilters and protect the aquatic life and the aquatic environment.
Since the liver is the primary organ for metabolism, then in the setting of liver injury there will be reduced metabolism of compounds such as hormones. If these hormones are not metabolized and degraded in the liver, then these hormone levels will increase.
<em>A particular example is that the hormone estrogen is increased in the setting of liver damage, causing males with liver failure to have feminine characteristics.</em>
The Gram-positive bacteria have a thicker cell wall than the Gram-negative bacteria.
Answer:
The correct answer is b. must be present in a population before natural selection can act upon the population
Explanation:
Genetic variation can be caused by mutation, recombination between chromosomes during meiosis and by fusion of two genetically different gametes during sexual reproduction.
This genetic variation is necessary for the evolution of any population. Natural selection acts on every individual and it decreases the frequency of those alleles that are not suited for the environment and increase the frequency of those alleles which helps the individual to survive in the changing environment.
Therefore genetic variation must be present in the population before natural selection act on the.
