In a population of mice, the presence of black spots is the result of a homozygous recessive condition. If the frequency of the

allele for this condition is 0.15, what is the approximate percentage of heterozygous genotypes in this mouse population? (Assume that the population is in Hardy-Weinberg equilibrium.)
12%
26%
72%
85%

If A is dominant allele, and a is recessive allel, than:

p is frequency of A allele, q is a frequency of a allele, p2 is a frequency of homozygous dominant genotype, 2pq is frequency of heterozygous genotype and q2 is frequency of homozygous recessive genotype.  

If the population is in Hardy-Weinberg equilibrium; p+q=1

p=0.15 q=1-0.15=0.85

2pq=2*0.15*0.85=0.255~26%

What is a metabolic pathway? see section 16.1 (page 337) . view available hint(s) what is a metabolic pathway? see section 16.1
Lunna [17]

The answer is a ‘series of steps in which enzymes work one at a time to convert a compound to a related compound’. The intermediate products of metabolic pathways are called metabolites. An example of a metabolic cycle is the Glycolysis and Krebs cycles. The product in each step of the metabolic pathways becomes the substrate of the next step in the pathway. There are two types of metabolic pathways; anabolic and catabolic

In humans, the hormone testosterone enters cells and binds to specific proteins, which in turn bind to specific sites on the cel
LuckyWell [14K]

Answer:

As a transcription factor

Explanation:

Testosterone is a male sex hormone secreted by the testicles which promote the growth of the male reproductive organs and the male characters like muscle buildup.

The hormone shows the paracrine effect and thus act on the target cell at distant. The mechanism of action of the testosterone is that it controls the gene expression of various other genes.

The testosterone binds the specific proteins which activate the expression of the gene that is they acts as a transcription factor which activates the expression.  

Thus, as a transcription factor is correct.

Mushrooms may look like plants, but they’re actually fungi. What are the similarities and differences between fungi and plants
Dahasolnce [82]
Similarities: both originated from “protists” and they have similar cell structures.

Differences: plants use photosynthesis to make food, while fungi cannot. Fungi does not possess chlorophyll, which is a key part of the photosynthesis process for plants.
