The correct answer is B.chloroplasts.

Chloroplasts are plant’s organelles so they cannot be found in a cell from fingernail. The function of chloroplasts is to convert light energy of the Sun into glucose that can be used by cells and this is possible thanks to chlorophyll found in chloroplast . The entire process is called photosynthesis.

8. In a population of beetles, there is a gene for color with two codominant alleles. The allele R leads to red beetles and the
Eddi Din [679]

Answer:

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

Explanation:

Given that:

The allele → R = Red beetles

The allele → B = Blue beetles

Since the gene color shows a codominant allele

The Red Beetle = RR

The blue beetles will be = BB

The heterozygous beetle will be = RB

∴

The punnet square showing the crossing of RB × RR is:

                R                   B

R                RR               RB

R                RR               RB

The result shows that we have two red beetles and two heterozygous beetles.

Hence;

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

Phosphorus in rivers can lakes sinks to the bottom and over thousands of years becomes ______ again.
pshichka [43]

Your question isn't the most clear, but I think your answer is rocks, or more specifically phosphorous rich rocks because the phosphorous will mix with the sediments on the river's/lake's ground forming phosphorous rich rocks.

That means that It'll become a phosphate mineral and later become phosphorous again when the minerals weather.



Hope it helped,
