Using the nonexperimental method, a researcher collects data on exercise and anxiety from a number of people and finds that exer

cise is negatively related to anxiety—that is, the people who exercise more tend to have lower levels of anxiety. What does this scenario demonstrate?

Answer:

Co-variation between variables

Explanation:

Based on the scenario being described within the question it can be said that this scenario demonstrates the Co-variation between variables. This refers to the measure of how much two seemingly random variables vary together as opposed to separately which would otherwise be variance. Which explains why when one variable changes in value the other changes in an un-correlated way.

Answer:

Co-variation between variables.

Explanation:

Co-variance refers to measurement of the relationship between two random variables. That is  how the two variables change proportionately, or  varies  with one another. However, it does not explain how the two variable depends on one another.

Thus when the two variables moves in the same direction with one another, it is called positive co variance. However, when they move in inverse proportion to  one another, they are negative co-variance.(as represented in the question).

Thus it shows how exercise and anxiety varies with one other, but it does not show how  they depend on one another.

The generation of a knock-out organism generally requires all the following EXCEPT ________. The generation of a knock-out organ
PilotLPTM [1.2K]

Answer:

knowledge of the sequence product

Explanation:

A gene knockout is a technique used in molecular genetics to deactivate target genes in an organism in order to study their functions by reverse genetics (i.e., gene loss). Knockouts are generated by different methods including, for example, homologous recombination or site-specific nucleases (zinc-fingers, TALENS, CRISPR/Cas9). These techniques require to know a priori the sequence of each gene to be knocked out in order to target desired mutations. In the last years, the CRISPR/Cas9 tool has gained attention to knockout genes of interest because it is a genome editing system that can be easily used for deletion or insertion of bases.

Explain E.O. Wilson's theory of Island Biogeography as it applies to environments other than islands physically
fgiga [73]

Answer:

The theory of E.O. Wilson's theory of Island Biogeography was originally developed as island biogeography, to explain species richness of actual islands, surrounded by water.

It proposes that the number of species found in an undisturbed environment is determined by immigration and emigration. According to him, the species richness will be the same if this island will have an equal number of the immigration and extinction or emigration of species.
