<h3>Research variables</h3>

In every scientific investigation, there are different variables. These include:

  • Independent variables: These are the variables that are supplied by the researcher and often varied to produce different effects. It is often referred to as the 'cause' variable.
  • Dependent variables: These are variables that are measured in the course of research. They are a result of the effects of the independent variable on the experimental subjects or groups. They are otherwise known as 'effect' variables.
  • Constant variables: Variables that are applicable to all experimental groups and are usually kept constant.

Also, there are different groups in research:

  • Control group: The reference group. The group that is not fed with the independent variable and forms the basis for comparison in order to understand the effects of the independent variable.
  • The experimental group: The group that is fed with the independent variable.

The question is incomplete. The complete question is:

A recent study compared the Homo sapiensgenome with that of Neanderthals. The results of the study indicated that there was a mixing of the two genomes at some period in evolutionary history. What data were discovered that suggested this conclusion

A) some Neanderthal sequences not found in living humans

B) a few modern H. sapiens with some Neanderthal sequences

C) duplications of several Neanderthal genes on a Neanderthal chromosome

D) some Neanderthal chromosomes that are shorter than their counterparts in living humans

Answer:

B) a few modern H. sapiens with some Neanderthal sequences

Explanation:

The mixing of genomes of two species generally results in shared sequences and some common genetic traits in the descendants of these species. Mixing of genomes of <em>Homo sapiens</em> and Neanderthals would have resulted in the presence of some common gene sequences in their genomes. If the conclusion that the mixing of genomes of these two species has occurred is correct, some of the modern <em>Homo sapiens </em>should have the genome sequences that were otherwise present in the genomes of Neanderthals only but not in that of the <em>Homo sapiens</em>.

Delicious77 [7]
The oldest client is at more risk for heart failure. A third heart sound is caused by a sudden reduction in the speed of blood flow from the left atrium to the left ventricle. It is said to be a normal phenomenon for young people and athletes but in older people who do not exercise, it indicates a congestive heart failure.

Which organs work together to make an organ
mafiozo [28]
Just as the organs in an organ system work together to accomplish their task, so the different organ systems also cooperate to keep the body running. For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce.
