Answer:
The correct answer is - involuntary contraction of the skeletal muscles.
Explanation:
Shivering or the chills that is involuntary action of body to maintain the homeostasis by controlling the body heat or maintaining body temperature it can cause by environmental change or the infection.
It is rapid involuntary contraction and relaxation of the skeletal muscles whenever body needs to produce heat when ti feels cold. Skeletal muscles are act as thermal effector in such cases.
Thus, the correct answer is - involuntary contraction of the skeletal muscles.
Given what we know, we can confirm that organisms that can grow with or without oxygen present are referred to as anaerobes.
<h3>What are some examples of anaerobes?</h3>
As stated previously, anaerobes are organisms that do not require oxygen in order to survive, some examples include:
- Staphylococcus
- Escherichia coli
- Listeria
- and many other forms of bacteria.
Therefore, we can confirm that organisms that can grow with or without oxygen present are referred to as anaerobes and they include many forms of bacteria such as the ones listed.

Answer:
P53, EGFR and KRAS genes
Explanation:
Mutations on somatic cells will disturbs the cell cycle and induce cell proliferation which lately results in tumour formation. The mutated P53, EGFR and KRAS genes causes lung cancer. P53 has direct contact with DNA acts a suppressor of tumour and guards the cell divisions. When these genes are mutated they induce expression of different genes (especially P53) leading to lung cancer.
