Answer:

anaerobic organisms do not require the presence of oxygen to produce energy in form of ATP, while aerobic organisms require oxygen

Explanation:

Anaerobic organisms produce energy by glycolysis, which is a metabolic pathway that produces ATP by transforming glucose to lactate when oxygen (O2) is limited. Glycolysis produces two (2) molecules of ATP per glucose molecule. Moreover, when O2 is available, aerobic organisms produce ATP by cellular respiration, which includes glycolysis, the Krebs cycle, and oxidative phosphorylation. Cellular respiration is able to produce thirty-eight (38) molecules of ATP per glucose molecule, thereby being more efficient than glycolysis.

11. Name and explain all of the stages of the water cycle.

crimeas [40]

Explanation:

Evaporation - the water from the oceans began to evaporate due to the heat of the sun and forms water vapour

In a 13-filament microtubule, the majority of lateral interactions are between like subunits, with alpha tubulin binding to alph

luda_lava [24]

Answer:

Lateral interactions between protofilaments are in general homotypic. The heterotypic interactions are weaker because these interactions involve the mix of different protofilaments within the microtubule .

Explanation:

Microtubules are cytoskeletal polymers that are formed by tubulin dimers in a head-to-tail arrangement (protofilaments).

Why can’t you identify archaeans by using Gram stain?

Slav-nsk [51]

Because Prokaryotes can be classified based on their shape and their Gram stain reaction. However, the Gram stain is not a reliable method of identifying archaea, as they do not contain peptidoglycan in their cell walls.
