The introduction of a new predator can cause a species to go extinct when the predators consumes the species faster than the species can reproduce.
Humans have approximately 20 000 genes, while they have only 46 Chromosomes - so we see there are a lot more genes than chromosomes and there must be multiple genes per chromosome - <span>B. Every chromosome is made up of many genes.
In fact, we know quite a lot about our chromosomes, but we don't even know how many genes exactly we have!</span>

The correct answer is:
(D) enzyme linked receptor
When non-nerve cells become involved in response to signals, the type of receptor that goes into action is the enzyme linked receptor.
Explanation:
An enzyme-linked receptor, also identified as a catalytic receptor, is a trans -membrane receptor, where the adhesive of an extracellular ligand produces an enzymatic action on the intracellular side. Hence a catalytic receptor is an integral membrane protein containing both enzymatic catalytic and receptor functions.
