Answer:
Protein is made up of 20 different amino acids. Each amino acid consists of a central carbon. This central carbon is bonded to an amine group (NH2), a carboxyl group (COOH), a hydrogen atom and an R group.
Amino acids can be linked together when the amine group of one amino acid is bonded to the carboxyl group of a different amino acid. The COOH donates an OH group and the NH2 donates a H. The OH and H come together to form a water molecule, so this process is called dehydration synthesis - water is removed to form something new. The bond which holds the amino acids together is called a polypeptide.
Explanation:
Damage to heart valves can lead to heart murmur.
Explanation:
Heart murmur refers to the sound of blood flow. The sound of flowing blood in the heart is usually not heard.
The heart murmurs can result due to two reasons that is either a damaged valve or any condition that causes the heart to beat at a faster rate.
The types of damage to the heart valve that may lead to heart murmurs are:
Mitral valve prolapse, Mitral valve or aortic stenosis and Mitral or aortic sclerosis.
Sometimes, the murmurs do not signify a serious condition but under certain condition they may indicate the risk of heart failure.
Answer:
Option d. None of the above
Explanation:
- Genes do not blend together at the level of genotype. In fact, genotype is a one of its characteristic features.
- The function of gene is to carry the genetic information whereas its the amino acids that code for a protein.
- Genes do not form cluster of genes through mutation, it is formed by divergence gene duplication.
X= -2
5x + 15 + 2x = 4x + 9
7x + 15 = 4x + 9 (subtract 4 from each side)
3x + 15 = 9 (subtract 15 from each side)
3x = -6 (divide by 3 on each side)
X= -2
