Yes. They do it to escape the winter. Hope it helps.
Answer: All of these
Explanation:
The polymerase chain reaction (PCR) revolutionized the field of molecular biology because PCR uses a small amount of DNA as a template.Paired with two primers which side to the target sequence, nucleotides, and thermostable DNA polymerase amplifies a specific region of DNA. In this way a large amount of DNA is obtained from a very small sample.
If the stimulus frequency is so high that the relaxation phase disappears completely, contractions become continuous in a process called complete tetanus.
What is tetanic contraction?
- When the motor neuron that innervates a skeletal muscle generates action potentials at an extremely rapid rate, a persistent muscular contraction known as a tetanic contraction is induced.
- A motor unit has experienced its motor neuron's maximum stimulation during this state, which lasts for a while. This happens when several impulses with a high enough frequency excite the motor unit of a muscle.
- Every trigger results in a twitch. A slow enough stimulus delivery will cause the muscular tension to release between each succeeding twitch. High frequency stimulation will cause the twitches to overlap, which will cause tetanic contraction.

The maxillary bones and mandible are part of A. the facial bones.
In fact, maxillary and mandible are primary bones of the face which also includes, nasal bones, zygoma, and frontal bone.
Both are found in the jaw area. The mandible bone is located near the lower jaw, while the maxilla is found near the nasal portion of the face.
