Ymorist [56]

Answer:

A

Explanation:

The dead matter from organisms such as plants and animals that die need to be recycled so the nutrients in the matter are released and used up by other organisms. This is how sustainability is achieved in ecosystems through a cyclical nature of nutrients flow. Decomposition of the dead matter is done by decomposers such as fungi and bacteria. Without them, the dead matter would accumulate while the soil would lack nutrients for plants to grow and for other bacteria to utilize for energy. This would affect the rest of the food chain/web causing the ecosystem to collapse.

The inhabitants of the planet Mendel have three alleles for hair color: red (R), white (W) and blue (b). The R and W alleles exh
Alex_Xolod [135]

Answer:

4 RW pink hair color

Explanation:

Let the allele for red hair color = R

Let the allele for white hair color = W

Let the allele for blue hair color = b

Since R and W exhibit co dominance it means none of both traits have the tendency or capability to masked the other .

As such individual with RW genotype = PInk hair color

Allele b is recessive and only individuals with the genotype bb exhibit the blue allele  

Now; if a cross occurs between a red-haired Mendelian and a white-haired Mendelian

i.e

RR   × WW

we have

           R           R

W         RW       RW

W        RW         RW

So we have the following offspring :

4 RW = 4 pink

So theoretically , the possible phenotypes results to 4 RW pink hair color
