The answer for this should be D
Answer:
Cysteine
Explanation:
<u>Determine the Amino acid that is primarily involved in Binding </u>
The Amino acid that is primarily involved in Binding is Cysteine. while the other Amino acid ( i.e. Histidine ) will be involved in Catalysis.
since the enzyme is functional at pH 6 to 8. and Cysteine has a pH of 5, it should be deprotonated and used primarily for Binding .
b) cytosine pairs with guanine in both. literally in dna replication,
<em>adenine goes with thymine</em>
<em>thymine goes with adenine</em>
<em>guanine goes with cytosine</em>
<em>cytosine goes with guanine</em>
hope this helps mina! :) <3
In the scenario give above, the disease reservoir is the PARROT and the possible transmission method is INDIRECT CONTACT THROUGH AIR.
Disease reservoir refers to a source of a particular pathogen in an environment. A disease reservoir can be a person, an animal or an inanimate object like soil. In the case given above, the parrot is the disease reservoir and it passes the disease pathogen to the student. Pathogens are transmitted through four distinct ways, these are: direct contact, indirectly through the air, indirectly through contaminated object and through vectors. The disease pathogen was possibly passed to the student when the parrot was talking via tiny mucus droplets that escape from the bird's mouth.
C. protein. Nitrogen is a component of amino acids which are the building blocks of protein.
