In a certain population of rabbits, the allele for brown fur is dominant over the allele for white fur. If 20 out of 100 rabbits have white fur, the frequency of the recessive allele (b) is 0.45. Therefore, the correct statement is option A.
What is Hardy-Weinberg law?Hardy-Weinberg law represents the relationship between the allele frequency and genotypes present in the population.
If the allele controlling brown fur is dominant over the allele controlling white fur, the Hardy-Weinberg equation can be used to calculate the frequency of the recessive allele.
Let the frequency of the dominant allele (B) is denoted by p and the frequency of the recessive allele (b) be denoted by q. If 20 out of 100 rabbits have white fur, which means that the frequency of the bb genotype is 20/100 or 0.2.
Using the equation, we know that: p^2 + 2pq + q^2 = 1
where p^2 represents the frequency of the BB genotype, 2pq represents the frequency of the Bb genotype, and q^2 represents the frequency of the bb genotype.
By substituting the knowing values, the value of q can be calculated:
0.2 = q^2
q = sqrt (0.2) = 0.45
Therefore, the frequency of the b recessive allele is 0.45.

How would plant populations be affected if the populations of decomposers,
such as earthworms, decreased dramatically?
O A. Plant populations would flourish because they would no longer be
preyed upon by earthworms.
O B. Plant populations would suffer because the soil would have fewer
available nutrients.
O C. Plant populations would be unaffected by changes in the
earthworm population.
D. Plant populations would flourish because they would not need to
compete with the worms for nutrients.
pleaseee helppppp
Answer: B. plant population would suffer because the soil would have fewer available nutrients.
Explanation:
Earthworms are called a farmer's best friend as they make the soil more fertile. When earthworms purify the soil it makes it easier for the plants to grow as the soil is mineral rich. Decrease in the population of earthworms would make it difficult for the plants to grow because of the less fertile soil.

During an earthquake, what is the most destructive type of seismic wave that caused a rolling motion?
1. P waves
2. S waves
3. Surface waves
4. Transverse waves
Answer:
Surface Waves
Explanation:
Surface waves cause more damage because they produce more ground movement and travel slowly, which makes it take longer to pass.
During an earthquake, the most destructive type of seismic wave that caused a rolling motion is known as a Surface wave. Thus, the correct option for this question is C.
What is an Earthquake?An earthquake may be defined as a sudden trembling of the surface of the earth. It causes great destruction, as a result of movements within the earth's crust or volcanic action. The circumstance of an earthquake is fatal to living organisms.
According to the context of this question, surface waves are those waves that significantly cause more threats to the surface of the earth. they effectively construct more ground trembling and movement. These waves travel gradually and this makes it take longer to pass.
Therefore, during an earthquake, the most destructive type of seismic wave that caused a rolling motion is known as a Surface wave. Thus, the correct option for this question is C.
