The heart rate slowed and eventually stopped.
In natural experiments, the researcher compares groups exposed or not to exogenous agents, but does intervene in group composition or independent variable modification. This is a natural experiment.
<h3>
What is a natural experiment?</h3>
There are two types of investigation strategies,
- Manipulative investigation
In a natural experiment the researcher does not intervene in the creation of treatment and control groups.
There is an exogenous agent, such as a natural phenomenon, that influences the study groups and that acts as the treatment.
The researcher takes advantage of these events to use these random groups to compare them in the study.
The researcher chooses exposed groups (experimental groups) that might have been affected by the natural event and other groups that have not been affected (control groups).
In the exposed example,
- Exogenous agent ⇒ Treatment ⇒ pesticide use
- Exposed group ⇒ Experimental group ⇒ birds from nests in pesticide-sprayed fields
- Not exposed groups ⇒ Control groups ⇒ birds from nests in unsprayed fields.
Since the researcher does not voluntarily modify the independent variable to observe a response in the dependent variable, this experiment could not be considered to be manipulative.
This is an example of a natural experiment in which the researcher chooses groups exposed to different conditions to compare them and analyze the effect of the pesticide.

A gene
is something that is passed onto you, pretty much like this: My dad had blonde hair and green eyes, and that's what I got. My mom was Brown haired and blue eyes. I got her eyebrows and mouth. Get what im saying? It's something that is passed down to you.
Answer:
IDENTICAL
Explanation:
<em>Daughter cells are cells that result from the division of a single parent cell. They are produced by the division processes of mitosis and meiosis. At the completion of the mitotic cell cycle, a single cell divides forming two daughter cells. A parent cell undergoing meiosis produces four daughter cells.</em>
