Answer:

The correct answer is c. contract; relax.

In the patellar tendon reflex arc, the patellar ligament is stretched, which stretches the quadriceps femoris muscle of the thigh. This reflex will cause the quadriceps femoris to <u>contract</u> and the hamstrings to <u>relax</u>.

Explanation:

The patellar reflex is the involuntary contraction of the quadriceps femoris muscles by flexion of the patellar tendon. The patellar tendon is located in the knee joint and connects the patella and the quadriceps tendon with the tibia. Tendons are structures of fibrous junction tissue that originate in the muscle and are inserted into the bone, they are the means of attachment between them. For this reflex of myothetic or stretching type to occur, it is essential to have the leg flexed and relaxed, that is, the hamstring is relaxed, which allows the extension of the leg (reciprocal inhibition).

Which occurs during transcription? DNA is copied to create a second DNA strand. mRNA codons and tRNA anticodons assemble amino a
Novosadov [1.4K]

During transcription, mRNA is synthesized using DNA as a template. This process usually takes place in the cell nucleus and is carried out with the help of an enzyme called RNA polymerase.

mRNA  plays the role of a messenger hence the term messenger RNA or  mRNA in short. Information for synthesis of a specific protein is transcribed on mRNA in the nucleus of the cell. The mRNA then leaves the nucleus and enters the cytoplasm and attaches onto a  ribosome. Ribosomes are cell structures fondly called the "work bench " of the cell.

It is in the ribosomes that the information brought by mRNA is translated or decoded and used to synthesize the specific protein that was coded for.
