Answer:
action spectrum of photosynthesis
Explanation:
<em>The action spectrum of photosynthesis represents the regions of white light that are utilized during the process of photosynthesis by green plants.</em>
According to studies, the action spectrum of photosynthesis corresponds to the blue and red regions of white light.
Hence, the two distinct regions of bacterial growth along the length of the filamentous algae observed by Engelmann represent the blue and red region of the white light.
As photosynthesis was taking place across the two regions, oxygen was being produced. Oxygen is necessary for the growth of aerobic bacteria and as such, they were able to grow across the regions where oxygen was being produced.
B. fossil record and carbon dating. I think thats right
1. All living things are composed of cells
2. Cells are the basic unit of structure and function in living things
3. All cells are produced from other cells
D.volcanic activity along the ring of fire
Acceleration = 3.7m/s^2
Using Newton's 2nd Law equation:
Force = Mass x Acceleration
You substitute the weight of 222N into force, this is because weight is the FORCE of an object due to gravity.
Rearranging the equation for acceleration:
Acceleration = Force/Mass
Substitute in the known values.
Mass = 60kg
Force = 222N
Acceleration = 222/60
Acceleration = 3.7 m/s^2
