A biologist used the Internet to contact scientists around the world to obtain information about declining amphibian populations

. He was able to gather data on 936 populations of amphibians, consisting of 157 species from 37 countries. Results showed that the overall numbers of amphibians dropped 15% a year from 1960 to 1966 and continued to decline about 2% a year through 1997. What is the importance of collecting an extensive amount of data such as this?

Answer:

The more the data collected the better the understanding of the extent of the problem.

Explanation:

In this case here, when more data are collected it makes it easier for the biologist to understand the cause and extent of the problem

Decreasing the rate of gene flow between two populations is likely to make the populations more different from one another. true
devlian [24]

The given statement "Decreasing the rate of gene flow between two populations is likely to make the populations more different from one another." is False.

<h3>What is gene flow?</h3>
  • Gene flow refers to the processes by which genes are transferred from one group to another.
  • Gene flow, which is a term used more frequently in anthropology, refers to the allelic change brought on by human movement.
  • Gene flow would reduce the isolation that could lead to speciation by increasing population similarity and reproductive kinship.
  • Gene flow significantly slows down speciation by recombining the gene pools of the groups and therefore repairing the growing variations in genetic variation that would have otherwise resulted in full speciation and the creation of daughter species.

Red-green color blindness in humans is inherited as an X-linked recessive trait. Usually, heterozygous females are not colorblin
Maksim231197 [3]

Answer:

The mentioned characteristics of variability are witnessed because of the phenomenon known as X chromosome inactivation in heterozygous females. As females possess two X chromosomes, they actually should not possess any color blindness.  

The phenomenon of X-chromosome inactivation takes place in a random manner at the time of embryo development. During this only one X chromosome is inactivated. If the chromosome comprising the defective gene is inactivated, the individual will possess normal vision.  

If the chromosome comprising the usual gene gets inactivated than the individual will be color blind. In the given case of female, X inactivation took place in one eye. The inactivation of normal alleles has taken place and thus she possesses normal vision with one eye and is color blind in the other eye.
