Answer:
b) contact transmission.
Explanation:
Contact transmission of pathogens occurs directly or indirectly between the source of the pathogens and the host organisms. During contact transmission by droplet spread, the pathogen is carried on smaller particles. These particles move through air for a very short distance, usually less than a meter. Therefore, droplet transmission of a pathogen requires that the source and host are present in close proximity.
NO, the protein solution do not have a high morality. The protein solutions generally have lower molarities. This is because protein molecules are larger in size and do not form a soluble and uniform solution. Protein molecules do not dissolve in solutions.
Answer:
The correct answer is The bridge between cystein which connects parts of a protein is stable but non covalent interaction.
Explanation:
Disulfide bond link the sulfhydryl group of two adjacent cystein residues in a protein structure.
Dulsulfine bond is stable but is not a non covalent interaction.Disulfide bond itself is a covalent interaction.
