5 0

Answer:

The correct answer is option ( B )

Explanation:

Carbon enters all food webs, both terrestrial and aquatic, through autotrophs, or self-feeders. In this process, the carbons of the molecule are released as carbon dioxide. Decomposers also release organic compounds and carbon dioxide when they break down dead organisms and waste products.

Hope it helps you

have a nice day

Scenario #1
Natasha_Volkova [10]

Answer:

p = 0.36

q = 0.64

p² = 0.13

2pq = 0.46

q² = 0.41

Explanation:

We need to use the Hardy-Weinberg equations:

p + q = 1

p² + 2pq + q² = 1

p: the frequency of the dominant allele

q: the frequency of the recessive allele

p²: the frequency of homozygous dominant

2pq: the frequency of heterozygous

q²: the frequency of homozygous recessive

Here, we know that 328/800 people are homozygous recessive, which means that q² = 328/800 = 0.41.

Then, q = √0.41 = 0.64, and p = 1 - q = 1 - 0.64 = 0.36.

Now, we have p² = (0.36)² = 0.1296 ≈ 0.13 and 2pq = 2 * 0.36 * 0.64 = 0.4608 ≈ 0.46.

The answers are:

p = 0.36

q = 0.64

p² = 0.13

2pq = 0.46

q² = 0.41

You have a plant with yellow seeds, which express a dominant phenotype. How would you determine the plant's genotype?. . . Condu
DENIUS [597]
If it displays the dominant genotype, we can assume that this plant would have a heterozygous (hybrid) genotype, i.e.

With a purebred recessive plant, the geneotypes would be 50% Bb and 50% bb.

With a purebred dominant plant, the genetpyes would be 50% BB and 50% Bb.

With a <span>heterozygous (hybrid) plant, the genotypes would be 25% BB, 50% Bb and 25% bb.</span>
