Answer:
A. Targeted exercise should improve the performance of a certain task. Repetition of specific exercises will help improve the given task.
Explanation:
The principle of specificity basically states that to be good at a certain task or skill, you need to perform that task or skill. If you want to improve the performance of a certain task, you need to do exercises that develop the skills that are specific to the task.
A little confusing, but to make it even simpler, you know the saying "practice makes perfect". In order to master the skill, it needs to be done repetitively. In the context of exercising or training, you need to do exercises that will develop your body to do the skill you want to achieve.
A swimmer for example, will not improve in swimming, if he or she does not swim. They can only get better if their training is swimming.

Answer;
the understanding that genes code for specific proteins
-The scientific discovery that spurred the rapid advancements in the fields of genetics is the understanding that genes code for specific proteins.
Explanation;
-Each gene tells the cell how to put together the building blocks for one specific protein. However, the gene (DNA) sits inside a different compartment of the cell (the nucleus) from the location of the cellular machines that make proteins (ribosomes).
-The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm. Translation, the second step in getting from a gene to a protein, takes place in the cytoplasm.
This scientific discovery spurred the rapid advancements in the field of genetics.
Protein
i hope that answer is right ;)
