 <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>

What are some possible future changes in the global climate?
Ugo [173]

The most probable future changes in the global climate are:

- Global warming;

If the levels of CO2 and methane increase enough in the atmosphere to be able to intensify the Greenhouse effect, than some portion of the ice on the planet will melt because of the rising temperatures, thus lifting up the sea level, creating more unpredictable weather with larger and stronger storms, but also making the mainland much drier. This would be a scenario if the continents are arranged like they are now, but if there isn't a sufficient mass of land on and around the poles, than all of the ice will melt and the sea levels will rise so much that the planet will come in the ''water planet'' scenario, and it will have wet tropical climate pretty much everywhere on the planet.

- Ice Age;

If there's a disruption in the warm ocean streams and some of them disappear, or the levels of nitrogen or oxygen increase in the atmosphere, the Earth will start to cool off, thus coming to a situation of an Ice Age. In this kind of situation, there will be large ice sheets on and around the poles that are stretching much further towards the lower latitudes, as well as mountains all over the world that are covered in snow and shaped by glaciers.

(04.03 HC)A scientist records the populations of two species over a period of time.
Lina20 [59]

Answer:

The likely explanation is that population 1 had traits which were more favorable to its survival than population 2's in the new conditions.  It wouldn't have to do with food competition, but the traits they already have that may or may not be conducive to their survival in the new conditions.

Explanation:

Let me explain. Say a drought occurred on an island. Population 2 relied on eating bugs that lived in the green grasses. Population 1 relied on eating cactus fruit, which is drought-resistant. Say that because of the drought, population 2 started to decrease since there were less bugs to eat because the grasses dried up. Population 1 is unaffected because the bugs they eat were still in abundance.

This all has to do with the concept of natural selection. Species with traits that are good for their environment will likely do well unless a change in conditions occurs which makes their traits no longer favorable.

Hope that makes sense!
