Answer: c - The proportion of the population that is heterozygous (Aa) for this trait is 0.50

Explanation: Percentage of those with homozygous recessive alleles (aa) in the population has been given as 25%. We can represent this as q².

Recall that Hardy-Weinberg provides the equation p² + 2pq + q² = 1, where

P² = homozygous dominant alleles

q² = homozygous recessive alleles

2pq = heterozygous alleles

q² = 25% = 25/100 = 0.25

q = √0.25 = 0.5

Also recall that for two alleles, p and q, p + q = 1.

Therefore, p = 1 - q = 1 - 0.5 0.5

Since we now have the values of p and q, we can calculate the proportion of heterozygous alleles (Aa) as 2pq = 2 x 0.5 x 0.5 = 0.5

vladimir2022 [97]

The replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.

<h3>How to calculate the Exponential growth/decay formula?</h3>

x ( t ) = x 0 × (1 + r ) t

  • x(t) is the value at time t.

  • x 0 is the initial value at time t = 0.

  • r is the growth rate when r/ 0 or decay rate when r < 0, in percentage.

  • t is the time in discrete intervals and selected time units.

Whit this information, we can conclude that the replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.

An organism has a metabolic pathway that is controlled by an inducer through negative regulation. When this organism is grown in
beks73 [17]

Answer:

The inducer will combines with the repressor and inactivates the pathway.

Explanation:

Inducer is a term in Molecular Biology, which represent a molecule or substance that has the capability to activate the transcription of a gene, where by it joins with and then inactivates a genetic repressor.

In other words, the inducer binds with the repressor in order to prevent the RNA polymerase to combine to the DNA, and chemically produce mRNA, this is done by repressor proteins combining with the DNA strand.

Inducer specifically makes repressor to change shapes, which will make it not combine with the DNA, and therefore, allow formation of transcription, such that expression of gene will eventually occur.
