16. What component of amino acid structure varies among different amino acids?
Group of answer choices

the glycerol molecule that forms the backbone of the amino acid

the presence of a central C atom

the elements bound to the alpha carbon

the long carbon-hydrogen tails of the molecule

14. Which answer correctly describes plant vs. animal cytokinesis?

Plant cells deposit vesicles containing cell-wall building blocks on the metaphase plate; animal cells form a cleavage furrow.

The structural proteins of plant cells separate the two cells; in animal cells, a cell membrane separates the two daughter cells.

The contractile filaments found in plant cells are structures composed of carbohydrates; the cleavage furrow in animal cells is composed of contractile phospholipids.

Plant cells divide after metaphase but before anaphase; animal cells divide after anaphase.

All of the other answers are incorrect.

11.

What provides the energy for the polymerization reactions in DNA synthesis?
Group of answer choices

DNA polymerase

nucleotides with three phosphates

breaking the hydrogen bonds between complementary DNA strands

ATP

Asorbtion of photons

Answer #1

16.

the elements bound to the alpha carbon

R group is the element that differ between amino acids and that will be attached to the alpha carbon atom of amino acids

Amino acid basic structure composed of corboxylic acid and NH3+ and a R group that differentiates

14.

Plant cells deposit vesicles containing cell-wall building blocks on the metaphase plate; animal cells form a cleavage furrow.

Plant cells having cell wall will have deposite cell wall components to separate the cells with cell wall on each daughter cells. Animal cells forms cleavage furrow where only membrane is enough

11.

nucleotides with three phosphates

In the upcoming nucleotides with 3 phosphate groups are broken down to produce the energy and attaches the nucleotide with 1 phosphate group to the growing chain
