Good luck on your questions! :D
Answer:
The correct answer is option - C. They replaced carbon dioxide with oxygen in the atmosphere.
Explanation:
Cyanobacteria or Blue-green algae is a group of bacteria that is making its own food using water and carbon dioxide in the presence of sunlight, the process of photosynthesis
These organisms release oxygen as a byproduct of photosynthesis in the atmosphere. Through this process, these organisms replaced carbon dioxide with oxygen in the atmosphere in the early earth.
Thus, the correct answer is option C. They replaced carbon dioxide with oxygen in the atmosphere.
Its hard to believe it but its D.<span />
Answer:
Most people were either doing they’re daily jobs and going to school, or traveling.
Explanation:
Answer:
1) in the direction of the applied force
2)when the movement is not in the direction of the applied force it is not work. But if a component, or part of the motion is in the direction of the applied force it is work.
3)Joules/sec
4)Force/displacement
6)Wedges and lever
5)conduction
6)radiation
7)there is no heat flow
8)The average kinetic motion of the particles increases, there is more thermal energy
9)The average kinetic motion of the particles decreases, there is less thermal energy
10)transverse wave
11) sound waves
12)they transfer energy through oscillations in matter
13)the speed of the pitched baseball
14)to detect speed and direction of blood flow
15)green and violet are reflected and red is absorbed
16)visible light
17)as heat
18)infrared light/infrared energy
19)reflection
20) yes, the forces emitted by having the same charge repells them.
21)the flow of electrons
22)You open the circuit and the electrons can't flow
23)You closed the circuit and the electrons can flow
24)I think you meant bipolar, this means 2 poles
