The anterior side of the heart is the side the uppermost point or peak is pointing to. The posterior surface lies opposite to the uppermost point.
<h3>What is heart?</h3>
The heart is a fist-sized organ that is located around the chest region or breast bone that pumps blood to the body. It's the primary organ of the circulatory system. The heart have four main chambers made of muscle and powered by electrical impulses. The brain and nervous system influence heart's function.
Therefore, The anterior side of the heart is the side the uppermost point or peak is pointing to. The posterior surface lies opposite to the uppermost point.

Answer/Explanation:
A mutation alters the sequence of DNA. Therefore, the mRNA that is transcribed from the DNA has a different sequence.
This mRNA goes on to be read by the protein synthesis machinery in the cell. The protein synthesis machinery translates the sequence of the mRNA into an amino acid sequence, which makes up the protein.
If the sequence of the mRNA is different, due to a mutation in the DNA, then the cell will translate a different sequence into an amino acid. This alters the composition of the protein.
Mutations can be small, and affect only one amino acid, or they could be huge, and impact the entire protein.
Mutations have very different consequences in gametes vs non-gamete cells.
If a mutation occurs in a gamete, that means the mutation will be passed on to the next generation, as it is contained in the DNA in the egg or sperm that becomes fertilised to make a gamete.
However, mutations that occur in other cells are not passed on to the next generation. That does not mean they do not have effects. E.g. mutations in the skin caused by exposure to UV rays from the sun can contribute to cancer, but would not be passed on to the individual's children

a control helps to increase the reliability of the results. it allows a scientist to compare it to other group(s) in an experiment. if a scientist notices a significant different btwn the control and the other groups, he can logically conclude that the independent variable has an impact on the dependent variable.
a variable is any factor, trait or condition that can exist in differing amounts or types. there are usually three tpes of variables in experiments: the independent, dependent and contolled. the independent variable variable is the one that is changed by the scientists to figure it's affect on something.
Answer:A genotype is the combination of two alleles, one received from each parent. The expression of a genotype is called the phenotype and the specific combination of the two alleles (the genotype) influences the physical expression (the phenotype) of the physical trait that the alleles carry information for.
