Answer:
Allele frequency
Normal allele 
Mutant r allele 
Genotype frequency
Homozygous normal bugs 
Homozygous mutant bug 
Heterozygous normal bug with one mutant r allele and one normal allele 
Explanation:
It is given that 99% of the bugs were killed after the spray of pyrethrum. This suggests that 1% of the bugs that were not killed must be homozygous for the mutant type allele "r"
Thus, the frequency of homozygous "rr" species i.e 
From this we can evaluate the frequency of mutant "r" allele.
Thus, 
As per Hardy-Weinberg first equilibrium equation, 
Substituting the value of q in above equation, we get
Thus, the frequency of homozygous normal bug is equal to
As per Hardy-Weinberg second equilibrium equation-
Substituting all the available values we get -
Allele frequency
Normal allele
Mutant r allele
Genotype frequency
Homozygous normal bugs
Homozygous mutant bug
Heterozygous normal bug with one mutant r allele and one normal allele
The correct answer is ATP or also known as Addenosine Triphosphate. ATP is considered to be a complex organic compound which participates in all processes of the body. It is considered to be the way to store the body's energy and the way to use it.
<h2>Option C is correct</h2>
Explanation:
Natural selection in an aquatic environment resulted in significant changes to whale forelimb anatomy
- Natural selection is the concept of evolution where organisms with favorable traits are selected(by nature) and reproduced and this process allows the organisms to adapt to the changing environmental conditions
- The upper forelimbs of humans and bats have fairly similar skeletal structures which means that they might share a common ancestor in skeletal structure but are functionally different which means they share a homology with each other
- The evolution of limbs of whales is also a part of forelimb adaptive evolution
- Gene mutation rates of higher animals are pretty much similar
- Whales are proper mammals and form a connecting link between fish and mammals
Your answer would be B) Renewable, Hope this helps!! :D
Answer: A single mutation can have a large effect, but in many cases, evolutionary change is based on the accumulation of many mutations with small effects. Mutational effects can be beneficial, harmful, or neutral, depending on their context or location. Most non-neutral mutations are deleterious.
