For this question, we will utilize a population of Martians that is in Hardy Weinberg Equilibrium. The dominant Martian phenotyp
Brrunno [24]

Answer:

d.0.48

Explanation:

When a population is in Hardy Weinberg equilibrium the <u>genotypic </u>frequencies are:

freq (AA) = p²

freq (Aa) = 2pq

freq (aa) = q²

<em>p</em> is the frequency of the dominant <em>A</em> allele and <em>q</em> is the frequency of the recessive <em>a</em> allele.

In this population of 100 individuals, 84 martians have the dominant phenotype and 16 have the recessive phenotype.

Therefore:

q²=16/100

q² = 0.16

q=√0.16

q = 0.4

And p+q=1, so:

p = 1 - q

p = 1-0.4

p = 0.6

The frequency of heterozygotes is:

freq (Aa) = 2pq = 2 × 0.4 × 0.6

freq (Aa) = 0.48

katovenus [111]

The another are differentiated from the anamniotes by the presence of their terrestrially adapted eggs. These eggs are protected by amniotic membranes. Development of these membranes have provided another with their own aquatic environment needed for development.

The development of amniotic membrane is a characteric of amniotic eggs. These membranes include: chorion' facilitating the exchange of gases between the embryo and the mother; amnion, protection the embryo from injuries and shock and also aiding hydration; allantois, excretion of nitrogenous waste such as urea and uric acid etc and also help in respiration.

Another characteristics is waterproof skin due to the presence of lipids.

Another is the existence of costal rib ventilation of the lungs: enables of loss of CO2 through the lungs rather than buccal pumping as foumd in anamniotes.

An atom with a net positive charge must have more
ArbitrLikvidat [17]
Must have more protons. Protons are positively charged, so if the atom (or in this case ion) has a net positive charge, it must have more protons (+ charge) than electrons (- charge).
