Answer: CO2 impacts the atmosphere because it causes temperatures to slowly rise over time. Oxygen produced from plants counter act CO2 with the carbon dioxide exchange but it still impacts the atmosphere to a certain level. it affects oceanic areas because it causes sea levels to rise, as well as increase the acidic levels in the water. hope this helps!
In artificial selection, nature provided the variation, and human selected those variations that they found useful
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.
Well, it helps us categorize organisms so we can more easily communicate biological information. Taxonomy uses hierarchical classification as a way to help scientists understand and organize the diversity of life on our planet.
