- Simple signs go through a speaker, an electronic gadget that expands the voltage, or quality, of the signs.
2. </span>repeater
- Review that a repeater is a gadget that recovers an advanced flag in its unique frame, without the clamor it may have beforehand gathered
Its made up of a molecule called nucleotides
Answer: The correct answer is- c. They do not live in the extreme environments.
Cell membrane ( also called plasma membrane) surrounds the cytoplasm of all cells and separates the internal environment of cell from its external environment. In bacteria, it is composed of phospholipids and many protein.
- Phopholipids are linked to ester in case of bacterial cell membrane whereas in archaebacteria, they are linked to ether ( that is they are linked to glycerol backbone).
The ether linkage in the cell membrane of Archaebacteria forms stable membranes that enable them to survive under harsh environmental conditions such as hot springs, boiling mud surrounding volcanoes, salt lakes,
Bacteria do not live under such conditions. Thus, bacteria lack ether-linked cell membranes.
Answer:
A
Explanation:
All involve the active transport of gases across membranes.
