The correct answer is: c. An operon is a region of DNA that codes for a series of functionally related genes under the control of the same promoter.
Operons contain cluster of genes that are transcribed together into mRNA or are not expressed at all. Formed mRNA undergos splicing to create monocistronic mRNAs so that can be translated separately. Operons are more often found in prokaryotic cells but it can appear in eukaryotic cells and in viruses.
There are different types of channels for blood flow that transport the blood pumped by the heart. They greatly differ only in the size of their diameters. Arteries are the big ones that are located mostly near the heart. Veins are the next which is where nurses inject you to gather blood. Then, the smallest ones are the capillaries.
Secondary consumers may be carnivores that eat meat or omnivores that eat both plants and animals.
<h3>What are secondary consumers?</h3>
Consumers in biology are organisms (heterotrophs) that uses other organisms for food in order to gain energy.
Consumers can either be primary or secondary. Primary consumers feed directly on plants, hence, are said to be herbivores.
On the other hand, secondary consumers feed majorly on primary consumers, making them carnivorous in nature.
However, secondary consumers may be carnivores that eat meat or omnivores that eat both plants and animals.
