Answer:
Explanation:
Only archaebacteria are capable of methanogenesis
Archaebacteria who use other forms of cellular respiration also exist, but methane-producing cells are not found in Bacteria or Eukarya.
Unique cell membrane chemistry. Archaebacteria have cell membranes made of ether-linked phospholipids,
Answer:
When calcium concentration increases during depolarization, it shifts the conformation of troponin and tropomyosin, and actin is able to associate with myosin. As calcium is taken up again by the sarcoplasmic reticulum the muscle cell relaxes.
The cessation of telomerase activity as we age limits the number of times a cell can replicate. current research on telomerases is particularly useful in the fight against cancer. This is because, Cancer cells employ a mechanism that activates telomerases, which leads to uncontrolled cellular division.
The body's stages of life are intimately correlated with telomerase activity. During the development of the embryo, the enzyme is active. High telomerase activity, which allows cells to divide endlessly, is a characteristic of cancer cells. In 85–95 percent of malignancies, telomerase is active (3,4).

Endocytosis -into cell
exocytosis -out of cell
so they are different.
