Answer:
Cell Membrane
Explanation:
The unique structure of the cell membrane allows small substances (like oxygen or carbon dioxide) to easily pass through.
Answer:
Explanation:
Soil is our life support system. Soils provide anchorage for roots, hold water and nutrients. Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites. We build on soil as well as with it and in it.
Answer:
b. His mitochondria lack the transport protein that moves pyruvate across the outer mitochondrial membrane.
Explanation:
The formation of pyruvate from glucose occurs during the process of glycolysis. It occurs in the cytoplasm. Pyruvate must enter into the mitochondria so that it is decarboxylated into acetyl CoA to enter into the citric acid cycle. Following this, NADH and FADH2 formed during glycolysis and citric acid cycle are oxidized by electron transport chain and the resultant proton concentration gradient drives ATP synthesis.
The given animal lacks the protein that transports pyruvate across the outer mitochondrial membrane. Therefore, pyruvate can not enter into the citric acid cycle and the animal can not derive energy by aerobic respiration of glucose.
The pyrenoids are located in the chloroplast
Plants that encourage the profileration of nitrogen fixing bacteria are called Legumes
