A student proposes that left-handedness is a recessive trait and is hidden in much of the human population. a survey of his clas

The frequency of the recessive allele for the left handle will be in this case equal to q^2 = 0.25 >> q = 0.5.

<h3>What is the Hardy Weinberg principle?</h3>

The Hardy Weinberg principle is a model used in population genetics to estimate genotypic and allele frequencies.

The Hardy Weinberg principle states that the sum of the dominant allele and the recessive allele in a population is equal to 1 (p + q = 1).

This principle also states p2 + q2 + 2pq = 1, where p^2 is the dominant homo-zygous allele, 2pq the heterozygous frequency and  q^2 the recessive homo-zygous frequency.

In this case, 9 individuals represent 25% (q^2 = 0.25), thereby the feecuency of q is equal to √0.25 = 0.5.

All of the following are transmembrane pumps that facilitate active transport except?
BigorU [14]

Answer:

b) Channel pumps

Explanation:

The channels are the transmembrane proteins that serve in the passive transport of substances down the concentration gradient. The channels can be gated or non-gated. The gated channels are opened and closed in response to certain stimuli such as electrical change.

For example, aquaporins are the gated water channels that transport the water across the plasma membrane. The process is driven by the osmotic gradient and does not use the energy of ATP.
