Answer:
option 1, 2, 4, and 5 are true while 3 is false.
Explanation:
statements are given below.
1) Anaerobic respiration occurs by either lactic acid or alcohol fermentation.
2) Glycolysis is the first step in anaerobic respiration only.
3) only anaerobic respiration produces a net gain of ATP.
4) anaerobic respiration occurs in the cells cytoplasm.
5) aerobic respiration always include the citric acid cycle.
Anaerobic respiration occurs by either lactic acid or alcohol fermentation and produces very low amount of ATP due to the absence of oxygen. Glycolysis refers to the breakdown of glucose molecule in pyruvate and ATP molecules. It only occurs in anaerobic respiration because it does not requires oxygen. Both aerobic and anaerobic respiration produces energy in the form of ATP. Aerobic respiration occurs in the mitochondria of the cell while anaerobic respiration occurs in the cytoplasm. Citric acid cycle is main part of aerobic respiration.
The fear of spiders is known as arachnophobia.
Answer:
pollen is important in fertilization because pollen carries male gamete and it helps in transportation of male gamete during fertilization in mainly gymnosperms and angiosperms.
Answer:
The movement of Loess
Loess are deposits of fine particles of silt and clay formed by the wind. It is known to be a deposits form vertical cliffs which is often forms a thick, rich soil.
The movement of sand forms the Sand Dunes.
A sand dune is formed when an obstacle (rock) slows down the wind causing some sand accumulation by the wind. The dune increases in size, slowly occupying the land as more sand is deposited by saltation (deposit of more grains of sand along the gentle slope).
