Answer:
Dominant
Explanation:
The dominant allele will always be shown in the phenotype if it's present, because the other allele would be dominant or recessive. If both alleles are dominant, then the dominant one shows, if one of the alleles is recessive, then the dominant allele would show over the recessive one.
I think of recessive alleles as "weak" where, they just follow behind whichever other allele exists there. If the other one is dominant, then the recessive one is behind it, and no one can see it. If it other allele is recessive, a recessive allele will be in front.
To solve this problem on genetic dominance, we will need a punnet square.
Let's let P represent purple-flowered and p represent white-flowered.
We have one purple flowered plant with the alleles PP, and we have one white flowered plant with the alleles pp. Using a punnet square, we can determine the alleles of the offspring.
<u>P</u> <u>P</u>
p| Pp Pp
p | Pp Pp
As we can tell from our punnet square, all of our offspring will have purple flowers. This is because the purple-flower allele is dominant and the white-flowered allele is recessive.
Since each flower has a dominant and recessive allele, they are heterozygous.
Therefore, the solution to this problem is D.
Answer:
The environmental factors which need to be investigated before clearing the land can involve living and non-living factors. The land clearing will remove species of animals and plants acquiring their habitat in the forest. The loss of floral species will affect the faunal species. The faunal species will extinct, decrease in number or may migrate to different locations. Therefore, complete loss of biodiversity will result.
This will also result in disturbance important cycles in nature like water, oxygen, nitrogen and carbon which will lead to disturbance of rainfall, seasonal or weather changes. Soil an important non-living factor will loose it's fertility due to soil erosion.
Answer: there might be single celled and very sensitive to change they might They are vitally important in the food chain and to the health of our planet.
