Mila [183]
The organelle you're looking for should be cholorplasts.

Chloroplasts are double membrane bound organelles, which is important for the process so photosynthesis. The outer membrane is smooth and gives the shape of the chloroplast, while the inner membrane forms sac that contains chlorophyll inside.

Chloroplasts exists in green plants that photosynthesize for energy, and they appear the most in mesohpyll cells, a type of cells in leaf.

Suppose a diploid mosquito is completely heterozygous at all 6 of its chromosomes (2n = 6). How many different combinations of g
Ket [755]

Answer:

8 different combinations of gametes can be produced by this mosquito, assuming no homologous recombination between chromosomes

Explanation:

The mosquito has 6 chromosomes. This means that means it has 3 pairs of homologous chromosomes. Basically, we can assume the number of different gametes by 2 to the power of 3 as their are 3 homologous pairs. This means 2×2×2 which will be equal to the amount of eight. Hence, eight different combination of gametes will be produced.

1. If the frequency of two alleles in a gene pool is 90% A and 10% a, what is the frequency of individuals in the population wit
Illusion [34]

Answer: 0.18

Explanation:

For the alleles, the percentage distribution of each is 'A' (90% = 0.9)

While 'a' (10% = 0.1)

Hence, 0.9 and 0.1 are the respective frequencies of each allele

Now, apply Hardy-Weinberg Equilibrium equation, where heterozygotes are represented by the 2pq term.

Therefore, the number of heterozygous individuals (Aa) is equal to 2pq which equals

2 × 0.9 × 0.1 = 0.18

Thus, the frequency of heterozygote is 0.18, while the percentage distribution in the population is 18%
