Answer:
Bilateral symmetry
Explanation:
the property of being divisible into symmetrical halves on either side of a unique plane. I am pretty sure itis this one, hope i helped you!
Answer: nucleus
Explanation: The nucleus contains the DNA which is a genetic material that contains all the instructions for protein synthesis. Before proteins are produced, the DNA is first of all copied into an single stranded RNA in a process known as transcription. This process takes place in the nucleus. The single stranded RNA then leaves the nucleus to the ribosome where protein synthesis takes place, there the RNA is translated into a polypeptide chain.
The smooth, but steady, increase in muscular tension produced by increasing the number of active motor units is called a recruitment.
Muscle tension is the force produced when a muscle contracts (or when sarcomeres shorten). The two primary forms of skeletal muscle contractions, isotonic contractions and isometric contractions, are produced when a muscle contracts against a load that is not moving.
- A load is transported as the length of the muscle varies during isotonic contractions, in which the tension in the muscle remains constant (shortens). Concentric and eccentric contractions are the two varieties of isotonic contractions.
- When a muscle contracts isometrically, the angle of a skeletal joint remains the same while tension is produced in the muscle. Sarcomeres shorten and muscles tense up during isometric contractions, but the load is not moved since the force generated is insufficient to overcome the resistance provided by the load.
