A climate zone is an area that is defined by two main factors. What are they?
MA_775_DIABLO [31]

Answer:

Temperature and precipitation.

Explanation:

Climate is defined as long-term climate patterns in a location. Looking at average temperature and precipitation through time is the simplest way to characterize the climate.

Temperature and precipitation are the two most significant factors in the climate of a place. Obviously, the annual average area temperature is significant, but the annual temperature range is important as well. Some locations range from the highest to the lowest temperature significantly wider than others. Average precipitation is very essential, but the annual change in precipitation is equally important. Some regions experience approximately the same precipitation year-round. For half of the year, other locations have very low precipitation while the other portion of the year has lots of precipitation.

Hypothesize whether prokaryotic cells might have been symbiotic before the evolution of eukaryotic
elena55 [62]
 <span>Two prokaryotes turning into a eukaryotic cell began with a process called

endosymbiosis. One large prokaryote engulfs (a process called

endocytosis) one small, aerobically respiring prokaryote. The small

prokaryote turned into a membrane-bound organelle, which prokaryotes do

not have, and like we know, only eukaryotes have membrane-bound

organelles. So that is how the eukaryotic cell structure evolved from

prokaryotic cells, meaning that before this evolution, they were most likely symbiotic.</span>
