This is because their cells are usually hypertonic to the freshwater they swim in. Their cells will always have dissolved osmotically-active molecules that are critical for cell function. Therefore, osmotically, water will move from the freshwater to the inside of the cells. If not regulated, the cells would swell and lyse. Therefore excess water has to be actively pumped out to maintain cell homeostasis.
Answer:
The correct answer will be amino acids.
Explanation:
The process of protein synthesis takes place in an organelle called ribosomes. The ribosome reads the information coded in the mRNA in the form of triplets of nitrogenous bases also known as "codons". The codons code for specific amino acids which are assembled or joined via peptide bonds in the ribosomes.
In the question, Katie wanted to make doghouse of the wood and nails in which if doghouse represents the protein, the nails and wood will represent the basic unit or monomer of a protein called amino acids which are put together by a hammer.
Thus, amino acids are the correct answer.

Bacteria can be SUSCEPTIBLE or RESISTANT to antibiotics. Susceptible bacteria can't grow if the drug (i.e., the antibiotic) is present.
Susceptibility to antibiotics occurs when bacterial colonies can't grow in presence of the antibiotic (e.g., erythromycin).
Some antibiotic-resistant bacteria include:
- Methicillin-resistant <em>Staphylococcus aureus</em> (it is one of the most common antibiotic-resistant bacteria)
- Vancomycin-resistant <em>Enterococcus</em>
