Answer:

The correct answer is microevolution.

Explanation:

Microevolution happens when there is a variation in the percentage of gene changes inside a set of inhabitants.

As its name tells us, <u>microevolution happens in a short period of time</u> and may simply be due to the fact that due to natural causes certain genes became stronger and more resistant from one generation to the other, or because within that population there was someone new who brought said improved gene. Other factors that can influence this small genetic change may be<u> migration, genetic drift or a single mutation. </u>

Therefore the answer to the given question is Microevolution.

Which of the following statements about secondary production is false!
hoa [83]

The statement about secondary production that is false is option c. Generally, an individual's production efficiency will decline as the C:N ratio of its food increases.

<h3>When is productivity and efficiency present?</h3>

Productive efficiency states that it is not possible to generate more of one good without producing less of another good given the inputs and technology at hand.

Note that Production efficiency is a word used in economics to describe the point at which an economy or other entity can no longer produce more of one good without reducing the level of production of a different one.

Hence, It's more important to focus on the caliber of your job than just the pace. Therefore, you have achieved improved production efficiency if your company increased its output from 1,000 bags to 1,500 bags of coffee while generating less waste, spending less money, and utilizing fewer resources.

A scientist thinks that he might  find serious inconsistencies in the  fossil record if he conducts an  excavation in a new location is refers scientific explanation because explanation is needed for it which can drawn from the scientific observation.

The rocks present in western Africa  and eastern South America formed  at the same place and at the  same time is scientific observation because the scientists takes the data.

Even if modern organisms are  found in ancient portions of the  fossil record, this wouldn't challenge the theory of evolution in any way is refers to scientific explanation.

The cloning of organisms is an  exciting area of study, and more  resources should be be devoted  to it so it is refers as scientific explanation.

The age, type, and composition of  ancient rocks in western Africa are  nearly identical to the age, type,  and composition of rocks in  eastern South America is scientific observation which is taken by the scientist through research.
