Answer:

Outcome variable (dependent variable)

Explanation:

In a scientific investigation, a DEPENDENT VARIABLE (also known as outcome variable) is the variable that is being measured. The dependent variable, as the name implies, responds to the changes made to the independent variable.

For example, in an experiment where the effects of different concentration of fertilizer is used to test plant growth (height), the HEIGHT OF THE PLANTS is the dependent variable because it is the variable being measured.

Answer:

The one treated with DNase and protease

Explanation:

<em>The samples that will transform yellow into purple if RNA is the genetic material are the ones treated with </em><em>DNase </em><em>and </em><em>protease</em><em> respectively.</em>

<u>The treatment of the heat-killed sample of the purple life with DNase will ensure that the DNA in the sample becomes degraded while treatment with protease will ensure that protein is degraded, leaving only the RNA. Thus, the RNA can be taken up by the yellow life form and become transformed into purple if indeed RNA is the genetic material.</u>

The sample treated with RNase cannot transform the yellow life into purple because the RNase catalyzes the degradation of RNA into smaller components.

Provide a summary of biologist Stephen Stearns’ findings in how Natural Selection may be working today in humans.
polet [3.4K]

Answer:

Stephen Stearns states that natural selection doesn't mean the survival of the fittest organisms, but rather this mechanism is illustrated by the selective reproduction of the fittest. Natural selection can be classified into distinct types, including directional, disruptive and stabilizing selection, which are in turn based on sexual selection. These types of selection are driven by different outcomes that have different dynamics.
