The answer is C. a diploid zygote
B. Genetic equilibrium has been maintained.
C. Mutations have arisen that may have altered allele frequencies.
D. Individuals with new genes have immigrated into the population.
The correct answer is option C, Mutations have arisen that may have altered allele frequencies
There have been several instances where mutation in the gene of an insect is caused due to the harmful external environmental condition which are either created or occurs naturally. Usually, the organisms evolve themselves to sustain in an adverse environment condition. In the process of evolution, they go through the process of positive genetic mutation but sometimes the mutation may also produce negative effect on the DNA of an species through wrong or inefficient pairing/coding. Here in this case it can be stated that the chemical sprayed on insects might have attacked the gene pool of the insects thereby producing adverse genetic mutation.
When a farmer sprays insecticide on crops, the DNA of the insects that are not killed can be damaged, leading to mutations that may alter allele frequencies in the population.
A farmer spraying insecticide on his crops to kill unwanted insects has the effect of damaging the DNA of the insects that are not killed. This can lead to mutations that may alter allele frequencies in the insect population. Hence, the correct answer is C. Mutations have arisen that may have altered allele frequencies.

The answer is liquefication
Answer: scientists collected fossils that showed species changing over time
Darwin collected specimens from around the world during the HMS Beagle voyage
Darwin proposed the theory of evolution by natural selection
Mendel proposed laws for how traits are inherited
Scientist examine evolutionary relationships using DNA sequencing
Explanation:
Answer: The correct answer is D) 313 K
The temperature of the person = 40⁰ C
We know that, 0⁰ Celsius = 273.15 Kelvin
This means that in order to calculate the Kelvin temperature, 273.15 is added to the Celsius temperature.
Thus, the temperature of the person in kelvin = 273.15 + 40
= 313.13 K
≈ 313 K
Thus, option D) is the right answer.
The study of genes and inheritance is called genetics. There are two types of alleles and these are recessive and dominant.
The correct answer is 75%.
Tall stems are dominant over short stems. Let T represent tall and t represent short. The parents are Heterozygous tall plants, which means that their genotype would be Tt and their phenotype would be tall. In a Punnett square it would look like this:
T t
T TT Tt
t Tt tt
Notice that we have 3 possible genotype combinations. When the dominant allele T is present that means that the phenotype that will be expressed is the dominant trait. In this case, we have the following genotype and phenotype:
TT Tall 1/4
Tt Tall 2/4
tt Short 1/4
The question is asking the chance the offspring phenotype is the same as the parent specifically so we can see that 3/4 are tall.
Hence, the correct is 3/4 = 75%.
