Answer:
D) Passing of electrons from Photosystem I to electron transport chain.
Explanation:
The NADPH is generated in the thylakoid membrane first in order to energize the second stage of photosynthesis (Calvin Cycle). Calvin Cycle takes place in the stroma, so that choice is out. Choices A, B, and C are in cellular respiration, and NADPH is not made in that process, so that leaves choice D.
<span>The correct answer is desert biome.</span>
Deserts are regions also called drylands because of the conditions found there (like a moisture deficit). Desert plants have to adapt to those dry and hot climates (sometimes without fresh water for years). Some plants have adapted by growing long roots that tap water from deep underground. Others, such as cacti, have special means of storing and conserving water (modifications of leaves for example).

Answer:Anaerobic Chemoheterotroph.
Anaerobic bacteria is a bacteria which breaks down its nutrients using carbon dioxide or in the absence of oxygen.
Chemoheterotroph is a bacteria which has the capacity to utilize nutrients in the form of chemicals and it can utilize organic nutrients also.
ANAEROBIC CHEMOHETEROTROPHS ARE BACTERIA WHICH FEEDS ON BOTH INORGANIC AND ORGANIC NUTRIENTS IN THE ABSENCE OF OXYGEN OR THE PRESENCE OF CARBON DIOXIDE.
