Color in McIver beetles is determined by two alleles at one gene locus. McIver beetles must have a heterzygous genotype (genotyp
seraphim [82]

Answer: The frequency of brown beetles is 0.32.

Explanation: The frequency of A1 allele is 0.8. As p+q=1, or the sum of dominant and recessive frequencies equals 1 or 100%:

1 - 0.8 = 0.2

In Hardy-Weinberg principle,

p^{2} + 2pq + q^{2} = 1

2pq represents the frequency of heterozygote individuals, so:

genotype A1A2 = 2*0.8*0.2 = 0.32.

Thus, the frequency of brown beetles (A1A2) in the population is 0.32.

The __________ of the heart rests on the diaphragm, and from its __________, the great vessels emerge (hint: not chambers)
Sergeu [11.5K]
The answer is apex and base. To simplify, the apex of the heart rests on the diaphragm and from its base, the great vessels emerge. In addition, blood vessels that are nearer to the pumping heart and must enlarge to endure pressure variations are named elastic arteries and foramen ovale permits blood to pass from the right to the left atrium, therefore avoiding to pass the fetal lungs.

What are some of the functions of photosystem i and photosystem ii in plants?
Sidana [21]

Answer:

Photosystem I (PS-I )and photosystem II (PS-II ) are two multi-protein complexes. These complexes contain the pigments used to absorb, harvest and catalyze the photons and light energy in the photosynthetic reactions. The main purpose of photosynthesis reactions to produce high chemical energy compounds.

Photosystem I and II are different from each other because of their absorbing wavelength of light. PS-I absorbs the longer wavelength of light than PS-II.

PS-I plays the major role in the production of high energy carriers ATP and NADPH using light energy (700 nm).

PS-II plays its function in the hydrolysis of water and ATP synthesis using light energy (680 nm).
