Answer: B
Explanation: That'd be based on how it's taken care of
The phenotype is - 75 % red and 25 %brown.
The genotype is hRhR - 25%
hBkhR - 50%
hBrhBk - 25%.
<h3><u>Explanation:</u></h3>
The cross given here is a simple dominant - recessive relationship between the three types of alleles of hair colour. The genes of this characteristics are present in autosomes, so will be segregated equally among all the sexes of the offsprings.
Now the genotype of auburn and red with black mother is given. So during gametogenesis, the gametes from the parents will be
Father - hBr and hR
Mother - hBk and hR
So, the probable combinations are hBrhBk, hBrhR and hBkhR.
The frequency of the combinations are 25%, 25% and 50% respectively.
The phenotypic ratio will be red : brown as 3:1.
The statement which is true about the scientific method is that "it is important to follow each step in order so the results are valid." Thus, the correct option is C.
<h3>What is the Scientific method?</h3>
The scientific method may be characterized as an approach to investigation in which a problem is determined, appropriate data are collected, an assumption is composed of these data, and the hypothesis has been empirically experimented with.
Scientific methods always deal with a scripted format of identifying the problem, making a hypothesis, collecting the data associated with a hypothesis, synthesizing a methodology, observing it, and making a conclusion.
Therefore, the correct option for this question is C.

Answer:
Deuterium, (D, or 2H), also called heavy hydrogen, isotope of hydrogen with a nucleus consisting of one proton and one neutron, which is double the mass of the nucleus of ordinary hydrogen (one proton). Deuterium has an atomic weight of 2.014
