Answer:
Distance = rate * time
Divide both side by time to get rate
Rate = Distance / time
5/.1 = 50 m/s
10/.2 = 50 m/s
Explanation:
Does that help? :)
Scientists found that the first living things were likely prokaryotic because eukaryotic are evolved from the prokaryotic only.
<h3>What do you mean by Natural selection?</h3>
Natural selection may be defined as favorable variations that assist the organisms to survive and reproduce in a particular habitat.
Individuals that are better suited to their environment are likely to have more offspring and pass their genetic material on to future generations. This theory is referred to as Natural selection.
Scientists hypothesize that oxygen began to accumulate in the Earth's atmosphere after the appearance of living things with the ability to Photosynthesize.

Answer:
energy; sun or food
Explanation:
If you are taking about animals, the second answer is food i believe.
If you are talking about plants, then it is sun.
But technically, sun helps us as humans and it also helps animals a lot with different things. So maybe just sun. Let me know.
Hope this helps!
Answer:
x=6/7, y=-228/35
Explanation:
-4x+5y = -36 /*3
15x-3y = 32 /*5
------------------------- here we multiply both equations to get common y
-12x+15y = -108
75x-15y = 160
------------------------- then we add these two equations to eliminate the y
-12x+75x+15y-15y = 54
63x = 54
------------------------- then we get the x
x = 54/63
x = 6/7 (after we divide both with 9)
------------------------ next up, we add the value of x in first equation
-4 * 6/7 + 5y = -36
-24/7 + 5y = -36
------------------------ we leave 5y on the left side
5y = -36 + 24/7
5y = -252/7 + 24/7
-------------------------- common divider is 7 so we multiply 36*7=252
5y = -228/7
y= -228/7/5/1
------------------------- now we leave only y on the left side
y = -228*1/7*5
y = -228/35
------------------------- when dividing the fragment we multiply outer and inner
