Well, you could use a stopwatch to measure the times of each swimmer.
Answer:
double helix
Explanation:
The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they called a "double helix," in the journal Nature.
Answer:
Cardiac output depends on the resistance mainly of the cardiac muscle walls.
Explanation:
The resistance of cardiac tissue also depends on its ability to distend in the sarcomero, that is, on the initial length of the contraction, the greater this, the greater the resistance, the greater the pumping efficiency, but the greater cardiac wear, this Situation occurs in people who are athletes or athletes since they have higher cardiac output but greater efficiency at the time of blood ejection, this is how they oxygenate the tissues better.
The definition of Epistasis in gene biology is Choice D: when the allele of one gene masks the phenotype of another gene
Definition:
When the phenotypic effect of alleles at one gene are masked by alleles of another gene.
In essence, a gene is said to be epistatic when its presence suppresses the effect of a gene at another locus.
It is important to know that Epistatic genes are often called inhibiting genes because of their effect on other genes which are described as hypostatic.
Additionally, there are six common types of epistasis gene interactions:
- Polymeric gene interaction,
