This is indicative of classical conditioning as studied by Pavlov. There is an unconditioned stimuli, in this case, Kendra’s nausea wherein nausea is not often associated with alcohol. The conditioned stimuli here is the smell of liquor which does not normally associate with nausea in other humans. In this case, Kendra’s nausea is now associated with the smell of liquor; yet another possible conditioned stimuli such as the sight of bottle was not associated.<span> </span>

Answer:
antimicrobial peptides
Explanation:
Antimicrobial peptides are short-chained amino acids that are produced as a result of the innate immune defense which can kill various pathogens such as bacteria, viruses, and fungi.
The structure of these antimicrobial peptides consists of a large portion of hydrophobic residues along with positively charged residues such as arginine and lysine.
Antimicrobial peptides employ the use of various mechanisms to combat the pathogens that enter the body. Some of these mechanisms are ;
1. Destabilizastion of membrane.
2. Formation of transmembrane channels
3. Functioning as immunomodulators.
Answer:
b. the bond between the phosphate groups is broken to release energy
Explanation:
- Phosphate groups are negatively charged => there is a pull between the two groups
=> it's easy to break this bond & ATP is unstable
=> ATP has a lot of free energy
- breaking the bond between phosphate groups makes the molecules more stable (aka contains less free energy)
=> delta G <0
=> breaking this bond releases energy
- the energy released by ATP is then used to transport large molecules against the concentration gradient
