The correct answer choice is answer B.) The fossil record provides evidence of a common ancestor to many species. Hope this helped!
Proteins contain 4 calories in every gram, while fats contains 9 calories for every gram, carbohydrates carbohydrates contain 4 calories in each gram. Therefore, 15 grams of carbohydrates contain 15 ×4 = 60 calories, 8 grams of fat will have 8×9= 72 calories and 8 grams of proteins contain 8×4= 32 calories. Hence, the total number of calories will be 60+32+72 = 164 calories
Answer:
Metabolize acetyl-CoA and produce ATP, carbon dioxide, and hydrogen ions.
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in the cells of living organisms, so as to produce energy in the form of adenosine triphosphate (ATP).
During cellular respiration, high energy intermediates are created which are then oxidized to make adenosine triphosphate (ATP). Also, the high energy intermediary products are produced at the glycolysis and citric acid cycle stage.
Glycolysis can be defined as a biological process that uses the energy released and stored during the Krebs cycle to form adenosine triphosphate (ATP). Thus, glycolysis is a series of chemical reactions that is typically used to break glucose into pyruvic acid.
Krebs cycle is also referred to as the citric acid cycle (TCA cycle) and it can be defined as a series of enzyme-catalyzed reactions used to release stored energy in most living organisms by metabolizing (oxidation) acetyl-CoA which are typically derived from proteins, carbohydrates, and fats.
This ultimately implies that, the Krebs cycle is a series of chemical reactions that metabolize acetyl-CoA and produce adenosine triphosphate (ATP), carbon dioxide, and hydrogen ions.

Answer:
In a diploid organism there are two copies of most genes.
The versions of the genes are called alleles.
Explanation:
Hello!
The genetic servants of a population are all variants of each of the genes present. These variables are possible thanks to the mutations that occur in the formation of the zygote (before or after fertilization).
When part of the DNA of an organism undergoes a point mutation (on one or a few nitrogenous bases) the body activates a series of responses to reverse it, however sometimes the mutation is maintained and can give rise to a change in a protein.
Sometimes and under certain circumstances (the change should not cause death or significant disadvantages in the body that is born) the mutation is maintained in the population giving rise to different alleles of the same gene.
In an organism there are two copies of each gene (genotype) but only one of them (phenotype) is expressed.
The allele of the gene that is expressed may depend on various factors but the dominant allele is usually expressed.
