The cell uses oxygen in the mitochondria which produces energy, without it the mitochondria makes lactic acid. Lactic acid affects muscles, and causes muscle soreness. That is if the cell is lacking oxygen, if it didn't get oxygen at all i would think that the affects on the body would be more severe.
Answer:
A scientific question is one where an investigation can be designed and completed to find out the answer without having to do multiple, entirely different investigations to get there. In a word, a scientific question is testable, but a non scientific question is not.
Answer: B) R group
Explanation: An aminoacid is composed by an amino group, an acid or carbonyl group and a side chain or R group, all bonded to a central carbon atom. Aminoacids are different between them for the R group and can be classified as: 1) Non-polar Neutral if the side chain is uncharged and non-polar (aliphatic or cyclic). 2) Polar Neutral if the side chain contains amida, sulfur or hydroxyl groups. 3) Basic if the side chain contains other amino groups. 4) Acid if the side chain contains other carboxyl groups.
Answer:
The correct answer is b. an amino acid
Explanation:
A tRNA is called adaptor RNA which have cloverleaf-like secondary structures. These structures contain stems and loops which make up the acceptor arm, anticodon stem and loop, D- stem and loop, and T- stem and loop.
Acceptor arm contains seven base pairs and four single stranded nucleotide which include conserved CCA sequence. The function of acceptor arm is attach amino acids require for protein synthesis.
The anticodon loop gives information to acceptor to attach a specific amino acid according to the sequence present in mRNA. The first amino acid which attaches to acceptor arm is methionine.
Thus, the correct answer is b. an amino acid.
