The atomic mass of an element is equal to the:

Biology
1 answer:
arlik [135]3 years ago
4 0

The answer should be the third option "number of protons and neutrons." The atomic mass of a element is equal to the amount of protons, and neutrons added together in that element. So for example if we are trying to find the atomic mass of hydrogen you would add the total amount of protons and neutrons together to find it's mass although it doesn't equal the exact amount of it's mass but it's close.

Hope this helps.

Suppose a population is carrying a condition controlled by two alleles: R (dominant) and r (recessive). Only homozygous individu
White raven [17]

<span><u>The answer is A. 72.25 percent.</u>

The Hardy-Weinberg principle can be used:</span>

<em>p² + 2pq + q² = 1</em> and <em>p + q = 1</em>

where <em>p</em> and <em>q</em> are the frequencies of the alleles, and <em>p²</em>, <em>q²</em> and <em>2pq </em>are the frequencies of the genotypes.

<span>The <em>r</em> allele (<em>q</em>) is found in 15% of the population:
q = 15% = 15/100
Thus, q = </span><span>0.15

To calculate the <em>R</em> allele frequency (<em>p</em>), the formula p + q = 1 is used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, </span><span>p = 0.85

Knowing the frequency of the <em>R</em> allele (<em>p</em>), it is easy to determine the frequency of the RR genotype (p²):
p² = 0.85² = 0.7225

Expressed in percentage, p² = 72.25%.</span>

Which phrase best describes the property of selective permeability?
belka [17]

Answer:

some molecules pass

Explanation:

The ability of a membrane to pass or not to pass a substance is its permeability (permeability).

Permeability is, in fact, the ease with which a dissolved particle passes through the membrane, which depends on both the properties of the particles and the properties of the membrane itself.

The membrane is semipermeable (semipermeable) or selectively permeable because it does not permeate all molecules.
