Answer:

The correct answer is - microevolution.

Explanation:

Microevolution is the very small evolutionary change specially allele frequencies on the level of species that occurs slowly over period of time. These changes occurs on the level of DNA or genetic level.

These evolution can be caused by the natural selection process or genetic drift over the generation of the species or population over period of the time. It is the study of the evolution that occurred on level of separated gene pool.

Thus, the correct answer is- microevolution.

Can amoeba have offspring with different genes and traits
stepan [7]

Here is your answer

No

______________________________

REASON:

Amoeba reproduces by the process of binary fusion which is an asexual mode of reproduction.

Since, in asexual method mitosis cell division takes place, same DNA material is transferred to the offsprings so no new traits and genes can be found in offsprings.

However in some case due to genetic drift or mutation, slight variations can be found in progeny.

But this is very exceptional.

A manager wanted to test whether the amount of noise in a clothing factory affected how
katrin2010 [14]

Answer:

When seeking to determine the number of shirts made by employees subjected to noise with and without the use of headphones, the dependent variable is the number of shirts made by the employee.

Explanation:

In a study or research, the dependent variable is the result of the intervention on the independent variable, which can be modified. In the case presented, the dependent variable is the quantity of shirts made by the employees, the number of which is measured at the end of the study.

It is expected that those employees who block the noise using headphones produce a greater number of shirts than those exposed totally or partially to noise.

For the other options:

  • <u><em>The amount of noise</em></u><em>. This can modified by the use or not of headphones and is the independent variable, subject to modification.</em>
  • <u><em>The type of music the employees listen to while they work</em></u><em>.  Does not represent dependent or independent variable.</em>
  • <u><em>The amount of training employees need</em></u><em>. It is not the variable being studied.</em>
