Answer: The frequency of brown beetles is 0.32.
Explanation: The frequency of A1 allele is 0.8. As p+q=1, or the sum of dominant and recessive frequencies equals 1 or 100%:
1 - 0.8 = 0.2
In Hardy-Weinberg principle,

2pq represents the frequency of heterozygote individuals, so:
genotype A1A2 = 2*0.8*0.2 = 0.32.
Thus, the frequency of brown beetles (A1A2) in the population is 0.32.
<h2>Answer with Explanation </h2>
The rice consists of a long chain of carbohydrate, so it has a high glycemic index which has an effect on blood sugar and insulin that is why white rice is avoided to be used for diabetic patients and if used then in a limited quantity. The type of carbohydrate which is present in rice is starch. This type of carbohydrate is good for growing up children and if a person is required instant energy can use this.
Answer is Chloroplasts have their own DNA.
Chloroplasts and mitochondria are the two cell organelles which have their own DNA. This DNA is separate from the DNA which is found in the nucleus of the cell. The DNA of both chloroplast and mitochondria can replicates and both can undergoes division. The DNA of both organelles produce many proteins and enzymes required for their function.
A statistical hypothesis, sometimes called confirmatory data analysis, is a hypothesis that is testable on the basis of observing a process that is modeled via a set of random variables.
