Answer: Primary
Explanation: The primary level of protein structure explains the sequence of amino acid linked together by peptide bonds to form polypeptide chains . A slight change in the amino acid sequence of Hemoglobin can alter hemoglobin function.
The primary level of protein structure is essential in the function of the protein any alteration in the amino acid sequence can disrupt the function of the protein.
Answer:
Day-to-day changes in weather can influence how we feel and the way we look at ... Meteorology is the science of forecasting weather.
Answer:
The correct answer is "The frequency of the B allele increased due to the selective pressures of the environment".
Explanation:
The missing part of the question is "Which of the following could best explain the increase in the frequency of the B allele in the population after five years?" at which the answer is "The frequency of the B allele increased due to the selective pressures of the environment".
In this study, the allelic frequency for black fur (B) in eastern gray squirrels Sciurus carolinensis changed from B=0.4 to B=0.6 within a lapse of five years. This increase is explained by the effect of selective pressures of the environment. For instance, is likely that new predators were more likely to detect squirrels with gray fur over black fur, or changes in the landscape benefited the black fur squirrels camouflage.
The R group should have the ability to form hydrogen bonds.
The R-group take a lot of different chemical forms and can
be acidic, basic, polar or non polar. Amino acids that are either acidic or basic
consequently have either positive or negative charge. These types of R-groups
are stabilized when surrounded by water.
C. Insulating the body
Insulating the body is not a function of a protein.
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.
