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,
Active transport is a type of transport that requires energy to move substances across a membrane. It occurs against a concentration gradient.
- The use of energy to move waste materials out of a cell is an EXAMPLE of transport active.
- Active transport occurs against a concentration gradient, whereas passive transport (i.e., diffusion) occurs in favor of a concentration gradient.
- Active transport can be mediated by membrane proteins that move substances from an area of high concentration to an area of low concentration.
- This movement (active transport ) usually requires the energy provided by the hydrolysis of ATP.
- Water molecules move across cellular membranes through membrane protein channels called aquaporins that act in favor of a concentration gradient (passive transport).

Answer:
Tubular re-absorption is the second major step in urine formation. Most of the re-absorption of solutes necessary for normal body function, such as amino acids, glucose, and salts, takes place in the proximal part of the tubule.
