Answer: False
Explanation:
Protozoans are not the organism that fix nitrogen for the plants. The organism that fix nitrogen to convert it into a form which can be used by plants are known as diazotrophs.
These are bacteria and archae that fix nitrogen gas found in the atmosphere into more usable form such as ammonia.
These organism can grow without any external source of fixed nitrogen. Example: Rhizobia and azospirillium.
Answer: See explanation below for answer.
Explanation: Mount Lico is an inselberg, meaning that it is an isolated mountain that rises abruptly from the surrounding plain. At the top of the mountain is a forest that lacks exploration and exploitation by humans.
The mountain is located the Zambezia province in northern Mozambique. It is 1,100 meters or 3,600 feet above sea level, and this is the major reason why it lacks exploitation by humans.
The features of Mount Lico that isolate the forest on top the mountain from the surrounding area are its height and sheer rock walls (which can be up to 700 meters).
III. enzyme pathways in the mitochondria produce ATP in a process that requires oxygen.
Answer:
Water
Explanation:
Molecular oxygen is the terminal electron acceptor and serves to receive electrons from reduced NADH and FADH2 to reoxidize them. NADH and FADH2 are formed during glycolysis and Kreb's cycle. These reducing powers should be re-oxidized to enter in the first two steps of aerobic respiration again.
For the purpose, NADH, and FADH2 transfer their electrons to the molecular oxygen via electron transport chain. After accepting the electrons, molecular oxygen is oxidized into the water molecule. Therefore, radioactive oxygen isotope would appear in the form of a water molecule after completion of cellular respiration.
