Answer:
The correct answer is <em>B. False</em>
Explanation:
<em>The genotype of an organism determines its phenotype</em>. Phenotype is constituted by observable characteristics of an organism. These characteristics are codified by genes, and the combination of the differents variants of a gene which codify a phenotipic characteristic constitutes the genotype. For example: eyes color is a characteristic. Its is codified by variants of a gene. The combination of two variants of a gene gives a genotype, which codifies for the phenotype 'blue eyes'.
Answer:
Because DNA molecules are extremely long.
Explanation:
DNA molecule is made up of only four types of nucleotides that are adenine, guanine, cytosine, and thymine. These four types of nucleotide encode all the information necessary for the formation and working of the entire organism because each DNA strand is as long as 2 meter which contains millions of base pairs.
The four nucleotides are arranged in the DNA strand with many different combinations which results in the formation of codons sequence that contains all the information about the cell. This long DNA is compressed several times to fit in the nucleus.
100% because the genotypes for the girls are FF and the man's are ff meaning all children will be Ff with the freckles trait

Lipids are macromolecules which provide insulation.
<span>A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.
