In trees and other plants, the presence of a cell wall gives the organism a protective barrier, contributing to its stiffness and rigidity, whereas animals lack this structure, allowing for greater movement.
Response:
B. The meanings of the prefixes chemo- and photo- point to the source of electrons.
Explanation:
The term chemo refers to chemical/drug, whereas photo relates to light. This can be demonstrated through the following examples:
Chemotherapy = treatment using chemicals
Phototherapy = treatment utilizing light
Adding twenty to four thousand thirty-eight results in needing to utilize a calculator for the computation.
Answer:
2.5 x 10¹⁰ ppt
5.0 x 10¹⁰ ppt
1.0 x 10¹¹ ppt
Explanation:
The term ppt denotes parts per trillion, meaning how many parts of the enzyme are present in 1 trillion parts. Percentage denotes the number of parts per 100 units. To convert the provided values from percentage to ppt:
The concentrations in ppt are:
2.5 x 10¹⁰ ppt
5.0 x 10¹⁰ ppt
1.0 x 10¹¹ ppt
Peptide bonds form through
hydrolysis or the removal of a water molecule (H₂O). Explanation:Two or more amino acids are
combined by generating peptide bonds, which ultimately lead to the creation of
polypeptides. These peptide bonds exhibit a
covalent nature and necessitate water, involving an
amino group and
a
carboxyl group. Hydrolysis of these components results in the formation of long-chain amino acids.
The arrangement of the amino acid sequence begins with the α-amino group residue and concludes with an α-carboxyl group at the end. This arrangement is referred to as the primary structure of the protein molecule.
