<span>D. The amount
of oxygen consumed by respiratory organisms balanced the amount of
oxygen produced by plants undergoing photosynthesis.

<span><span>There are a lot of created theories in which biologists engaged themselves to explain such phenomenon that occurred thousands of years ago, and experts say such study is hard to replicate, the start of prokaryote cells. Prokaryotes were said to be the first organisms that existed and were able to exhibit photosynthesis that produced oxygen that spread across the atmosphere. Hence, consider the Theory of Spontaneous formation of organic moleculeswhich suggests that the early earth had less to none oxygen. Thus, the atmosphere was abundant with the gases, CO2 and N2 with some other small amounts of H2, H2S, and CO. Hence, in Stanley Miller’s experiment when electrical sparks or “lightning” came in contact with these gases, the newly formed mixtures of CH4, NH3, and H2 were catalyzed. With these newly formed gases in interaction with H2O came the first synthesized some amino acids that compromised the earliest organic molecules which evolved to macromolecules, to be organelles of a cell. Which in the latter macromolecules are in today, maybe have been before the early nucleic acids (able to replicate) or proteins of these early cells.</span>

Answer:
A) Photoautotrophs
Explanation:
Tbh Im not entirely sure but photo means light and it seems like the most likely answer
The answer is B. Cell membrane and cytoplasm
The system that is affected when the xylem tissue is removed in plants
is water transportation. The scientific name for this process is
transpiration, and without the xylem tissue it would not be possible for
this process to occur.
A place being warm or cool depends on the climate of the region which in a way depends on the altitude and latitude of a place. Altitude is the height of any place above the sea level while the latitude resembles the position of a place with respect to the equator. Thus even though a place is at equator it may be cold because of its height above the sea level like wise though a place is at enough height above the sea level it may be warm due to its nearness to the equator.
