Which phase of cellular respiration is always anaerobic?
a. krebs cycle
b. glycolysis
c. transition
d. electron transport system

b. glycolysis

Explanation:

Anaerobic glycolysis is a catabolic route used by many types of cells for the degradation of glucose in the absence of oxygen. That is, glucose is not completely oxidized to carbon dioxide and water, as is the case with aerobic glycolysis, but fermentative products are generated.

It is called anaerobic glycolysis since it takes place without the presence of oxygen, which in other cases functions as the final acceptor of electrons in the mitochondrial transport chain, where large amounts of energy are produced from the processing of glycolytic products.

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
