Lets say that the genotypes are:
Male affected:XbY
Male unaffected: XaY
Female affected: XbXb
Female carrier: XaXb
Female unaffected:XaXa
P: XbY x XaXa
F1: XaXb XaXb XaY XaY The middle square is female carrier.
P:XbY x XaXb
F1: XaXb XbXb XaY XbY The left square is affected female.
P:XaY x XbXb
F1: XaXb XaXb XbY XbY The right square is affected male.
The correct answer is option C, that is, saves species from extinction.
The Endangered Species Act is one of the most essential and efficient environmental laws of America. It signifies a willingness by the people of America to work in harmony and restore and protect the species most vulnerable of getting disappeared forever.
The act offers common sense, balanced solutions for the landowners, government agencies, and concerned citizens to preserve the endangered wildlife and their habitats. It includes three prime elements:
1. Inhibiting the listed species from getting harmed or killed
2. Developing plans to restore healthy populations
3. Safeguarding habitat important to these species survival.
I believe the answer is respiration
Answer:
The likely explanation is that population 1 had traits which were more favorable to its survival than population 2's in the new conditions. It wouldn't have to do with food competition, but the traits they already have that may or may not be conducive to their survival in the new conditions.
Explanation:
Let me explain. Say a drought occurred on an island. Population 2 relied on eating bugs that lived in the green grasses. Population 1 relied on eating cactus fruit, which is drought-resistant. Say that because of the drought, population 2 started to decrease since there were less bugs to eat because the grasses dried up. Population 1 is unaffected because the bugs they eat were still in abundance.
This all has to do with the concept of natural selection. Species with traits that are good for their environment will likely do well unless a change in conditions occurs which makes their traits no longer favorable.
Hope that makes sense!
Answer:
DNA Replication
Explanation:
Ensures that resulting cells contain entire genome
