The fallopian tube brings a mature ovum to the uterus.
Answer:
A. Chemical modification may allow for extended drug capacities such as expanded spectrum of activity and increased stability.
Explanation:
Any modification in antibiotic structure and chemical will affects its ability in a way to increase it capability of target microbes and act efficiently. These modification can increase half life and stability of the drug.
Answer:
Cohesion: Hydrogen Bonds Make Water Sticky
Explanation:
Cohesion: Hydrogen Bonds Make Water Sticky
In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.
I think the correct answer from the choices listed above is option B. During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will <span>stop moving across the membrane. This is because equilibrium has already been achieved and there is no more driving force which is the concentration gradient present.</span>
The antigen-binding sites of an antibody molecule are formed from the molecule's variable regions which are described as so because their amino acid sequences can be different on different antibodies.
The specificity of antibodies is determined by the variable regions found at their endpoints. Antibodies are specialized proteins secreted by B-cells of the immune system. They are also called immunoglobulins. They contain four polypeptide chains that comprise two heavy chains and two light chains to form a Y-shaped molecule.
The variable regions, more specifically the hypervariable regions of an antibody, have a high ratio of different amino acids with the most common amino acids provided in one place. The variable region serves as the antigen-binding site while the constant region found below the variable region is determined to invade the antigen.
Antibodies are preserved in our body to identify the antigen the next time it encounters. They send the signals to the other body parts to reject the antigen and invade it.
