The answer for this one is b) Looping of DNA
The density of ice does not affect its melting rate because there is more to melt in the same size but adding objects will affect the melting rates because there is less to melt
Answer:
3, 1, 4, 2
Explanation:
The effects described are called phototropism, where light affects the direction of growth of the plant.
Auxin is a plant growth hormone that promotes growth of the plant by encouraging cell proliferation.
Light degrades auxin, so it is found more in the shaded side of the plant. This causes the cells in this region to proliferate more, and therefore there is more growth on the shaded side of the plant.
This causes the plant to bend towards the light.
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.
