Answer:
CRISPR-Cas9 is a DNA modification technique derived from a bacterial defense mechanism.
This breakthrough innovation allows the deletion and insertion of genes in a simple, fast and efficient way, much like "DNA scissors".
The CRISPR-Cas9 method is increasingly used in laboratories because it has several advantages over the DNA cutting enzymes developed before it.
First advantage, it is much easier to use (compared to other gene-editing tools). It has already allowed several teams of researchers to target several genes at once, including in human cells.
Other major advantages resulting from the simplicity of the system: its speed and its low cost. The CRISPR-Cas9 method takes only a few days (instead of a few months) and is at least ten times less expensive than those used before.
CRISPR-Cas9 is therefore a tool of disconcerting ease to modify the genome of many types of cells (to produce a protein for example), in bacteria, plants, animals and perhaps one day in humans.
The resource that you do not need to measure for research involving competition between animals is Light . The correct option is A
<h3>What is light availability?</h3>
The presence or amount of light in a specific setting is referred to as light availability. The amount and type of light that is available for organisms to perceive and use for a variety of biological processes are referred to as available light.
Although diurnal/nocturnal activity patterns and other characteristics of an animal's behavior or physiology might be influenced by light availability, light is not often thought of as a resource that animals directly compete for.
