Anika [276]

Recycle and renew are the two R's that uses and transforms the waste material. Recyclables do not equate to renewable as recyclable materials do not occur naturally.

<h3>What are recyclable and renewable?</h3>

Recyclable is the resources that are used finite times over and over and undergo a certain process for re-use purposes.  They can be naturally or by humans, processed to be used again.

Renewable is resources that are natural and are replenished in nature when gets decreased by natural processes.

Some recyclables like aluminum and glass are not renewable as they are not formed naturally and do not get replenished by natural processes.

Therefore, recyclables are not renewables.

Scientists have discovered homeotic genes in many kinds of organisms, including fruit flies, mice, and humans. These homeotic ge
love history [14]

Answer:

D

Explanation:

The presence of homeotic genes shows that all of the listed organisms (mice, flies, humans etc) all evolved from a common ancestor.

(A) is wrong as the evidence of the same gene existing in vastly different species shows the evolutionary relationship between these organisms.

(B) is wrong as there is insufficient evidence to prove that flies are the precessor of humans. We do know that flies and humans have evolved from a common ancestor though.

(C) is non-conclusive as the passage said nothing about the gene allowing the species to have a higher chance of surviving and reproducing. Hence, an errornous claim.

(D) is the correct answer as from a common ancestor, all of the listed organisms undergo and accumulates mutation, undergoes selective pressures that resulted in divergent evolution (aka branching evolution that results in many noval species forming) after millions of years.
