Because the stomach is lined by a mucous membrane (the gastric mucosa)
Answer:
Messenger RNA (mRNA) carries the instructions for making proteins. Like DNA, proteins are polymers: long chains assembled from prefab molecular units, which, in the case of proteins, are amino acids. A large molecular machine* called the ribosome translates the mRNA code and assembles the proteins.
Get the provisions you have, if any and get to the lowest part of your house, ie basement or ground floor, away from windows
Answer:
The correct answer is 6 genotypes
Explanation:
The most known case is two alleles of one gene (A and a), and we know the possible genotypes formed are three: AA, Aa, aa. Therefore, for a given number of alleles n, we calculate the number of possible genotypes as the sum of integers between 1 and n.
- For 2 alleles (n=2, the sum of integers between 1 and 2): Genotypes= 1 + 2= 3
⇒ For 3 alleles (n=3, the sum of integers between 1 and 3): Genotypes= 1 + 2 + 3= 6
So, we have 6 genotypes for 3 alleles (W1, W2 and W3) and they are:
W1W1
W1W2
W1W3
W2W2
W2W3
W3W3
Answer:
Enzymes change shape during chemical reactions. activation energy of a reaction.
Explanation:
Enzymes speed up chemical reactions by reducing the activation energy of the reactants. The substrate fits in the active site on the surface of the enzyme. The enzyme change shape during chemical reaction by the formation of an enzyme-substrate complex.
