Answer:
Only P-, F-, and V-class pumps transport ions.
Explanation:
The distinct classes of ATPases include:
1) Only the P-type ATPase actively transports ions across biological membranes. P-ATPases (also named E1-E2 ATPases) are found both in plasma and organelle membranes. These ATPases serve to transport ions and phospholipids by hydrolyzing ATP to ADP and phosphate.
2) A- and F-ATPases synthesize ATP by transforming the energy from a gradient of ions across the cell membrane.
3) V-ATPase (also known as Vacuolar-H+ ATPases) acidifies vacuole, lysosome, endosome and Golgi membranes. This type of ATPase couples the hydrolysis of ATP to the active transport of protons across biological membranes.
4) E-ATPases hydrolyze extracellular ATP.
Answer: False
Tropic rain-forest resides within the tropic of cancer and tropic of Capricorn, there are also rain forest in temperate areas between the tropics of cancer and Capricorn .Tropical rain forest has hundreds of tree species but temperate rain forest have only about 10-20 tree species . Temperate rain forest mostly have most animal insect and reptile life at ground level but in tropical rain forest life spans from the ground to tree tops
Answer:
the possible genotypes are LL and Ll
Explanation:
LL and Ll give dominant trait which is pricly leaves
Step-by- step-Explanation:
- Archaebacteria are very similar to Bacteria with respect to their cell size,prokaryotic organisation,circular DNA etc.
- Archaebacteria very similar to Gram-positive bacteria on the basis of cell structure.
- Both bacteria and Archaebacteria have several similar Metabolic Pathways.
- Unlike Bacteria Archaebacteria are habitants of extreme climates like hot springs and ice capped continents.
Thus Archaebacteria are much alike to Eubacteria.
Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.
