Answer:
Answer is all the options are correct. A, B, C and D.
Explanation:
Systematists are the biologists that developed system of classification and naming of organisms.
On this aspect, gross morphological traits described the collective structures of an organism. It referred to all the structures that are found internally and externally.
The biochemical traits and molecular traits described the genetic variability of an organism. In this case, they explained that trait is an important feature in an organism.
The behavioral traits described some actions which are particularly found to be specific to certain species of organism.
The reason which have caused Antarctica’s climate to change from a more temperate climate to its current climate is being revealed by the first option. It is a well known fact that movement of tectonic is the most powerful thing that influences on the climate. So, the right answer is <span>a. movement of tectonic plates</span>
The answer is Consistency
4 different phenotypes may be produced. If you write this down in a Punnet square you can get the exact ratio and the genotypes along with the phenotypes.
Let us assign B for brown eyes, b for blue eyes; H for right-handed, h for left-handed.
The mother's genotype will then be bbhh
The father's genotype will then be BbHh
bh bh bh bh
BH BbHh BbHh BbHh BbHh
Bh Bbhh Bbhh Bbhh Bbhh
bH bbHh bbHh bbHh bbHh
bh bbhh bbhh bbhh bbhh
Now based on that you can see that there are 4 possible genotypic combinations which would express different phenotypic combinations as well.
BbHh: Brown-eyed, right-handed
Bbhh: Brown-eyed, left-handed
bbHh: Blue-eyed, right handed
bbhh: Blue-eyed, left-handed
So again, there would be 4 possible phenotypes.
