Answer:

The correct answer is option A. "hydrogen atoms".

Explanation:

The energy producing reactions that occur in the sun take place by a process known as nuclear fusion or the proton-proton chain. Basically, tons of atoms of hydrogen are being converted into helium, which releases heat and energy. If a scientific team is trying to re-create the nuclear fusion of the sun they would only need hydrogen atoms, since the fusion of the hydrogen atoms is the reaction that produces helium atoms, heat and energy. However, the scientist team must recreate the tremendous gravitational forces of the sun to produce the nuclear fusion of hydrogen.

An examination of racial classifications from around the world indicates that Group of answer choices the best racial classifica
Vikki [24]

Answer:

the classification of racial types is an arbitrary, culturally specific process.

Explanation:

Racism can be defined as an act, practice or policy by an individual, group of people or institutions which typically involves promoting the ideas and belief that a race is superior in comparison with another. Thus, it simply means the believe that a particular race has dominance over another (an inferior race).

An examination of the classifications of races from around the world indicates that the classification of racial types such as Africans, Americans, Indians, Asians, Black-Americans, Hispanics, etc., is typically based on individual perception, not objective and an impulsive (arbitrary), culturally inclined or specific process.

This ultimately implies that, the classification of racial types is considered not to be based on any form of objective distinction but may be defined by a person's culture.

A culture can be defined as the general way of life of a group of people living together in a particular location or society.

Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.

How does understanding respiration help in maintaining a person's he health?
Marianna [84]

Answer: Respiration is a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.

Hence, respiration helps to maintain a persons health.

What is true concerning hemoglobin.
Fynjy0 [20]

Answer:

A protein molecule present in the RBCs, which helps in the transportation of oxygen from the lungs to the different parts of the body and brings back carbon dioxide, that is, collected from different parts of the body back to the lungs is known as hemoglobin.  

The general features of hemoglobin are that it comprises four molecules of protein in the form of globulin chains. In adults, the molecules of hemoglobin comprise two beta-globulin chains and two alpha globulin chains, while in infants and fetuses, the beta chains are least found, and is substituted by two gamma chains.  

Each globulin chain comprises an essential iron-containing compound porphyrin, which is termed as heme. Together both iron and heme play an essential role in circulating oxygen and carbon dioxide in the blood. This iron gives the red appearance to the blood.

Suppose the human trait for freckles is controlled by a simple dominant and recessive relationship at one locus. Freckles, F, is
Dennis_Churaev [7]

Answer:

0.549 is the frequency of the F allele.

0.495 is the frequency of the Ff genotype.

Explanation:

<em>FF </em>or <em>Ff</em> genotypes determine freckles, <em>ff</em> determines lack of freckels.

In this class of 123 students, 98 have freckles (and 123-98= 25 do not).

If the class is in Hardy-Weinberg equilibrium for this trait, then the genotypic frequency of the ff genotype is:

q²= 25/123

q²=0.203

q= \sqrt{0.2

q= 0.451

<em>q </em>is the frequency of the recessive f allele.

Given <em>p</em> the frequency of the dominant F allele, we know that:

p+q=1, therefore p=1-q

p=0.549 is the frequency of the F allele.

The frequency of the Ff genotype is 2pq. Therefore:

2pq=2×0.549×0.451

2pq=0.495 is the frequency of the Ff genotype.
