One of your friends is reading a newspaper article, which notes that, in rats, there is a positive significant relationship betw

een sugar consumption and obesity. the more sugar a rat consumes, the higher its overall body mass. your friend asks you what it means that the results of this experiment were statistically significant. what do you tell him?

The answer is: The fact that rats that consume more sugar have higher body masses is not due to chance. In addition, statistically significant is the probability that an affiliation among two or more variables is triggered by something other than random chance. The statistical hypothesis analysis is used to define whether the outcome of a data set is statistically important.

Fofino [41]

Protists are a group of organisms that are characterized as Eukaryotes that are neither plants nor animals nor fungi. They are very diverse, and there are many hypotheses about their classification. The cladogram for protists is constantly changing and, sometimes, there are opposite hypotheses that both have data to support them. What is the implication of a changing hypothesis.

In a population of rabbits, there are 496 black rabbits and 27 white rabbits. Fur color is determined by a pair of alleles where
Troyanec [42]

Answer:

0.96

Explanation:

It is given that

B is the dominant allele which represents the black color

and b is the recessive allele which represents the white fur.

B being dominant will result into black color fur for genotype "Bb"

Given -

Frequency of black fur allele (p) is 0.8

As per Hardy Weinberg's  first law of equilibrium

p + q = 1\\

Substituting the value of p in above equation, we get -

q = 1-p\\q = 1-0.8\\q= 0.2

q represents the frequency for white fur allele

Frequency of white fur phenotype is

q^2\\= 0.2^2\\= 0.04

Frequency of homozygous black fur phenotype (BB) is

p^2\\= 0.8^2\\= 0.64

As per Hardy Weinberg's second law of equilibrium -

p^2 + q^2 + 2pq = 1\\0.64 + 0.04 + 2pq = 1\\2pq = 1 - 0.68\\2pq = 0.32\\

Combined frequency of homozygous and heterozygous black fur phenotype is

0.64 + 0.32\\= 0.96
