Question

A scientist hypothesizes the temperature at which an alligator’s egg is incubated will determine whether the alligator will be male or female. The independent variable is
A. The temperature
B. The gender of the alligator
C. The incubator
D. The male alligators

Answer 1

Hint: To answer this question, we first need to understand what temperature is. Temperature is a physical number that describes how hot or cold something is. When a body comes into contact with another that is colder or hotter, it is the manifestation of thermal energy, which is present in all matter and is the source of the occurrence of heat, a flow of energy. A thermometer is used to determine the temperature.


Complete step-by-step solution:
In terms of cause and effect, independent and dependent variables are the variables you believe are the cause, while a dependent variable is the effect. In an experiment, the independent variable is changed and the outcome is measured in the dependent variable.
The object on which the observation will either influence or be influenced by the other item or variable is referred to as a variable. As a result, in a study or typically an experimental study, variables are separated into two parts: the independent variable and the dependent variable. The independent variable is a variable that can stand alone until it has an effect on the dependent variable, which is the variable that has been influenced by the independent variable.
IV: Gender of the alligator
DV: Temperature at which the alligator mother will need to supply.
So, we conclude that, the factor that we assess in an experiment is referred to as the independent variable. Temperature of an alligator's egg affects whether the alligator is male or female in this case, hence temperature is the independent variable.
So, the final answer is option (A) The temperature.

Note: A crocodilian belonging to the genus Alligator and the family Alligatoridae is known as an alligator. The American alligator and the Chinese alligator are the two extant species (A. sinensis). Fossil remnants have also revealed the existence of several extinct alligator species. Alligators initially appeared some 37 million years ago, during the Oligocene epoch.
