Is made up of which of the following is both dna and rna
Lactase refers to an enzyme that can dissociate lactose sugar into glucose and galactose. This enzyme plays an important role in the digestion of milk that comprises high lactose sugar. In case, if a mutation occurs in the gene codon of lactase, then two possibilities can take place. These are as follows:
1. Loss of mutation: In this case, the person becomes lactose intolerant because of mutation in lactase gene codon. Due to this, there is low mRNA expression and thus low production of the enzyme lactase. This is also known as lactase non-persistent phenotype.
2. Gain in mutation: In this case, the person gain an increase in mRNA expression of the lactase gene, thus more production of lactase takes place than usual. This kind of individual exhibits lactase persistent phenotype.
Answer and Explanation:
The difference between a food chain and a food web:
<u>Food Chain</u>
- Only one possible direct line of energy going through organisms
- Consists of usually 4-6 organisms
<u>Food Web</u>
- Multiple links that branch off in a web-like form, with some organisms being interconnected with each other.
<u>The answer is the third option: A food chain represents one possible pathway that energy and matter can take in an ecosystem. A food web contains multiple, interconnected food chains and describes how energy and matter moves through an entire ecosystem.</u>
