Chemical digestion is the biochemical process in which macromolecules in food are changed into smaller molecules that can be absorbed into body fluids and transported to cells throughout the body. Substances in food that must be chemically digested include carbohydrates, proteins, lipids, and nucleic acids

What factors allow a pool of 20 amino acids to produce thousands of unique proteins? (select the 3 that apply.)?

dsp73

The possible answers are:
A. Variation in length of the amino acid backbone
B. Each protein is encoded by a distinct gene
C. Variations in the type of peptide bond
D. Variations in the glycosidic linkage
E. Variation in tertiary structure
<span>F. Variations in which amino acids are used

The correct answers are A,E and F
There are only 20 amino acids that make all of the proteins in our bodies. However, there are options for protein variation are almost unlimited.
Firstly, you can vary the number of different amino acid that you use to make a protein.
Secondly, you can also vary the length of the amino acid chain.
And thirdly, when an amino acid chain is formed different parts of the chain interact with each other, bonding chemically, forming different 3-dimensional structures of the protein.
All of this contributes to the vast variation in proteins.</span>

What type of chemical energy is produced during photosynthesis

True [87]

Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.

Punnett Squares are used by geneticists to determine the likely genotypes of the offspring of two parents.

PilotLPTM [1.2K]

That's correct - it's a square where on one axis, the paternal allele (allele = one of the possible forms of the same gene), and on another the maternal allele is listed. Often, it's also indicated whether an allele is recessive or dominant.

Then, in the table that results, all the possible "combinations" of allele between the paternal and maternal party are created. If you count how often a certain combination appears, it indicates the likelihood of that combination.
See the picture (though it is directly from Wikipedia, please note). The likelihood of BB is 25%, of Bb is 50%, and of bb 25%.
