<u>Answer:</u>
B. Theories are broad explanations based on many observations and experiment
This statement accurately describes a scientific theory
<u>Explanation:</u>
Scientific theory can be defined as hypothesis which have been supported through research which is using the scientific method. Hypothesis is simply educated guess. It is the beginning stage of the scientific theory
There are many characteristic of scientific theory. These characteristics are testable, replicable, stable, simple and consistent. A theory explains the findings made throughout the review process. A scientific theory may not be the scientific test's final outcome; Scientific theories are interpretation of scientists. It can be changed or sometimes also rejected.
The answer is 0.42.
According to the Hardy-Weinberg equilibrium:
p + q = 1
p² + 2pq + q² = 1
where p is a frequency of a1 allele, q is a frequency of a2 allele, p² is a frequency of a1a1 genotype, 2pq is a frequency of a1a2 genotype, q² is a frequency of a2a2 genotype.
If <span>70% of the gametes produced in the population contain the a1 allele, then:
p = 70% = 0.7.
If p = 0.7 and p + q = 1, then q = 1 - p = 1 - 0.7 = 0.3
So, the proportion of </span>the flies that carry both a1 and a2 (a1a2 genotype) is:
2pq = 2 * 0.7 * 0.3 = 0.42
Answer:
Genetic drift involves the loss of alleles from a population by chance. Random fluctuations in allele frequencies in small populations reduce genetic variation, leading to increased homozygosity and loss of evolutionary adaptability to change
