Homeostasis is defined as the process of resisting change in order to maintain a stable environment. It typically involves negative feedback loops as these loops prohibits the change to occur in the human body system and maintain a constant internal environment. While positive feedback is the process of amplifying the stimulus produced within the body.
Homeostasis is thus regulated by negative feedback loops and rearely regulated by the positive feedback loops.
Answer:
The correct answers are "will not" and option B. "unit elastic".
Explanation:
The authors of an article in the New York Times about the New York Metropolitan Opera (the Met) suggest that the popularity of opera might be increased if the ticket prices for the opera are reduced, but in order to do so, the Met should receive a very generous economical gift. The authors of the article make this statement based on two assumptions: first, the Met will not increase its revenue as a result of the gift (therefore the money will be used to support a reduction in the ticket prices) ; and second, the demand for tickets to the Met is unit elastic (the demand would increase proportionally to the reduction in price, therefore the popularity of opera might be increased).
Answer:
If an individual has a dominant phenotype it is not known what the exact genotype is. For example with the phenotype of brown eye color , the genotype could be heterozygous.
Explanation:
Dominant is a trait that shows dominance over a recessive trait. The dominant trait might have a heterozygous or homozygous genotype.
For example, if the brown eye is a dominant phenotype, it might be that a person might have a heterozygous genotype for this trait. One of the alleles might be the dominant one while the other allele might be recessive. In such a case, the effect of the recessive trait is masked by the dominant trait. Hence, the organism shows the dominant phenotype but has a heterozygous genotype.
