The right option is; an experimental investigation, because it allows for the control of variables.

The best type of scientific investigation for Bena to use to study this is an experimental investigation, because it allows for the control of variables.

Experimental investigation is a type of scientific investigation in which variables are controlled, modified, and measured in order to obtain facts to buttress or oppose a causal relationship. Experimental investigation includes all the parts of an experiment such as observations, scientific question, hypothesis, procedure, variables (independent and dependent) etc.

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.
