Answer:
The heart has four chambers: The right atrium receives blood from the veins and pumps it to the right ventricle. The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen. The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.
Explanation:
Irina's claim is not found here but evidence from an experiment might include the amount of a product (chemical) or the order of nucleotides (biological evidence).
<h3>What is scientific evidence?</h3>
Scientific evidence refers to the observations that can be used to support (or reject) a working hypothesis.
Scientific evidence is variable depending on the field but it is always collected by observational or experimental procedures.
In conclusion, Irina's claim is not found here but evidence from an experiment might include the amount of a product (chemical evidence) or the order of nucleotides (biological evidence).

Answer:
Few crosses
The complexity of cat genetics
Crosses not controlled by the researcher
Explanation:
The purpose of this question is to determine why Megor Grendel is less famous than that of Gregor Mendel.
Gregor Mendel examined pea plants, which have a number of benefits for deducing genetic rules, including:
- The researcher has total control over the crosses.
- Because the peas have both self and cross-fertilization, it is possible to alter the crosses in the simplest way possible.
- Pea plants may be examined for a greater series of generations than cats or other animals.
- Because plant genetics is not overly complicated, several traits may be investigated at the same period.
As a result, the primary factors why Megor Grendel's experiments are not well-known:
- The presence of only a few crossings: It is impossible to establish a genetic theory with such a small number of crossings on the test subject of the organism.
- Cat genetics is too complicated therefore, the fur gene color on the X-chromosome, a characteristics mosaic inheritance. As a result, It is much too complicated to deduce an inheritance pattern.
- Crossings that the researcher cannot fully control. Unlike plants, crosses in animals cannot be totally controlled by the researcher.
As a result, it is impossible to draw any conclusions from them.
