The BRCA 1 and BRCA 2 genes are two genes that are sought in the genetic study of an individual in order to seek a predisposition to breast cancer (in women and also in men).
The genes of Tay-sachs, are researched in order to diagnose or eliminate Tay-sachs disease.
The first difference lies in the goal of the research: for the BRCA (screening) genes, a predisposition is sought and for the Tay-sachs genes, it is sought to confirm the disease.
The second lies in the technique used:
The first step in the study of these genes is to isolate and replicate them. The best technique for this is the PCR (polymerase chain reaction). By using primers we can amplify the gene we want. So the primers used in BRCA and Tay-Sachs research are necessarily different.
<span />The scientist that collaborated with Theodor Schwann was Matthias Schleiden this collaboration happened when Matthias Schleiden stated that plant tissues were made up of cells.
We have that the statement best explains why it is so <em>hard </em>to control Pest is
They quickly become resistant to <em>pesticides </em>in certain environments.
From the question we are told
- Which statement best <em>explains </em>why it is so hard to
- control mosquitoes, fire ants, and other unwanted insects?
<h3>
Insects Control</h3>
Generally Mutation and adaptation is a big part of insect life as the times come they mutate and change
Therefore
They quickly become resistant to <em>pesticides </em>in certain environments.

"Predators" directly control the balance of plant eating wildlife (and some omnivore and carnivores as well).
Answer:
<em>The correct option is A) Cognitive development</em>
Explanation:
<u><em>Skills such as listening and speaking, reading and writing require brain development. The development of the brain is a part of cognitive development. </em></u>
In simple words, cognitive development means the growing ability of a child to understand his surroundings and perceive information.
It is the ability by which a child becomes aware of his/her surroundings. It initiates thoughts in a child and also makes him realize how he should respond in a particular situation.
