Describe the forms that water takes through out the water cycle
Aleks [24]

Gas: when the water has evaporated and is now out in the air. Water molecules move super fast during this stage.

Liquid: Water molecules have a good amount of space to move around, but they aren’t traveling as fast as they do in the gastric state.

Solid: ice in other words, the water molecules are super tight and compact, but are still moving around, just not very fast.

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>

Moths can be black or white. in highly polluted areas the tree bark of trees is dark, which allows the black moths to blend in.
Valentin [98]
The reason for the loss of color after the industrial revolution is that the light-colored moths were "selected against" by predators. These birds could only see the light ones against the newly dark, sooted background. Over time, these predators could no longer distinguish the dark ones from their natural dark, sooted background. Thus more light-colored moths stood out against the dark soot, and were eaten. And more dark-colored moths eluded the birds, survived to reproduce, passing on more of their dominant genes for dark color to their offspring. After several decades of hundreds of thousands of generations, most of the later generations were dark, due to selective advantage of camouflage to survive predation.

Why do chicken eggs grow larger compared to other eggs?
Aloiza [94]

Answer:

Chicken eggs grow larger compared to other eggs due to their relative body sizes.

Explanation:

Egg laying and the size of an egg is relative to the size of the organism. So an ostrich lays a really large egg because it is a larger animal and can handle that size. Whereas a bluebird lays a small egg because it is a small bird.
