Answer: c

Explanation: Plants and animals need nitrogen to make proteins but they cannot take it in from the air. Because nitrogen is unreactive as a gas, it has to be transformed into a new molecule. When bacteria in the soil takes nitrogen from the air, it becomes nitrates. Finally, it can move through the food chain in this form.

This cluster of gene transcribed together to give a messenger RNA which further give rises to protein.

operator in operon is the site where repressor binds.

promoter is where Mrna binds , where our genes are transcribed

structural genes, they code for the enzyme that are involved in this metabolic pathway.

Maru [420]

Answer:

The correct answer is "change".

Explanation:

The missing options of this question are:

A. natural selection.

B. immutability.

C. survival of the fittest.

D. change.

The correct answer is option D. "change".

The scientific racism that was prevalent during Charles Darwin books publications was related to the concept of "pure races", and the association of the inheritance of the "superior attributes" related to these races. Darwin's ideas were incompatible to this scientific racism, since Charle Darwin theories support the idea of a constant change among all people attributes, produced by genetics behavior and exposure to environmental factors.
