Answer:
Radio waves, microwaves, infrared and visible light can all be used for communication.
Answer:
Summary. Multiple types of evidence support the theory of evolution: Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).
Explanation:
Brainliest is appreciated, have a nice day :)
It depends on the integrated activity of its organs
Answer:
the frequency of the resistant allele after one generation is 0.989
Explanation:
Given that :
A farmer plants Bt cotton that is genetically modified to produce its own insecticide.
Of the cotton bollworms feeding on these Bt plants, only 5% survive
i.e the survival rate s = 5% =0.05
unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide
Frequency of R allele = 0.01
In order to determine what will the frequency of the resistance allele be after one generation of cotton bollworms fed on Bt cotton; we need to first determine the frequency of the recessive allele r.
According to Hardy-Weinberg Equilibrium ;
p+q = 1
Let p = R and q = r
R + r = 1
0.01 + r = 1
r = 1 - 0.01
r = 0.99
Now; the frequency of the resistance allele after one generation can be calculated as :

where ;
q' = R
q = r



q' = 0.989
Thus; the frequency of the resistant allele after one generation is 0.989
A. They share or give away their protons.
