Answer: 1. Energy drink

2. What people prefer to drink.

Explanation:

1.The independent variable can be referred to that variable that can be manipulated in an experiment. The energy drinks can be changed to see that what people prefer to drink.

2.The dependent variable can be referred to that variable which is the result of the experiment it is influenced by the independent variable. What people prefer to drink is the dependent variable.

3.The data being collected in this experiment will be quantitative. As we can calculate the response of people what they prefer to drink in numbers.

Answer: 60%

Explanation:

In population genetics, the Hardy-Weinberg Principle states that the genetic composition of a population remains in equilibrium as long as no natural selection or other factors are active and no mutations occur.

The frequencies of the genotypes of an individual locus will be set to a particular equilibrium value.<u> It also specifies that these equilibrium frequencies can be represented as a simple function of the allelic frequencies at that locus</u>. In the simplest case, with a locus with two alleles A and a, with allele frequencies of p and q respectively, the principle predicts that <u>the genotypic frequency for the dominant homozygous AA is p^2, that of the heterozygous Aa is 2pq and that of the recessive homozygous aa, is q^2. The allele frequency of a is represented as p and the frequency of recessive allele is q.</u>

The three genotypes AA : Aa : aa appear in a ratio p² : 2pq : q². If we add them up, we get the unit:

p^2 + 2pq + q^2 = (p + q)^2 = 1  

And p + q = 1

<u>Rh-positive genotypes are represented as AA (homozygous dominant) or Aa (heterozygous) since the presence of a single dominant allele is sufficient to express the phenotype. While Rh-negative genotypes are represented as aa. </u>

If 84% of the population is Rh-positive, that means that this percentage includes all those who are AA and Aa. Then 16% are aa.

F(aa)=q^2=0.16

then F(a)=q=0.4

And since p + q = 1, p + 0.4 = 1, then p is 0.6

We can also calculate the rest, then F(AA)=p^2= 0.36

So F(Aa)= 2pq = 2 x 0.6 x 0.4 = 0.48

Notice that 0.36 + 0.16 + 0.48 = 1

Zielflug [23.3K]

Answer:

According to a recent report it was found that 48.7% of residents in Franklin county Ohio are registered to vote. Which of the following is more likely.

We have no basis for predicting which is more likely to have an proportion less than 45%

Explanation:

Since the actual population is unknown it is difficult to ascertain the proportion that will vote even though we have a raw data of those eligible to vote which might not be up to that during voting.

In which environment would you find dolphins?
gavmur [86]

The correct answer is option D, Pelagic.

The pelagic zone comprises the water column of the open ocean and can be further differentiated into areas by depth. In deep water, the pelagic zone at certain occasions is known as the open-ocean zone and can be contrasted with water, which is close to the continental shelf of the coast.

Or it can be said, that coastal water not near the bottom is still regarded to be in the pelagic zone. The tunas, sharks, and big marine mammals, like dolphins and whales travel in these waters.
