Answer:
Explanation:
Paleontologists are scientists that study the history/existence of past lives by collecting and examining fossils. They use these fossils to determine the history and age an organism has existed. Fossils are remains of dead organisms (plants and animals) which serve as evidence of past lives that have existed on earth in the past. They could include bone remains or footprint of this animals.
Fossils (from bones) are however mostly incomplete because they decompose before they are "stored naturally" by sediments which covers them. When scientists discover this incomplete fossils, they are compared (if there has been similar fossils discovered before then) and are stored and transferred to the lab for examination. This examination includes anatomical comparison (to determine relatedness with other fossils/organisms), carbon dating (to determine age) and data comparison (which includes location and type of soil and habitat).
I believe the answer would be 16:1
This can be looked at by assuming the motor speed is say 2000 RPM. Through the first reduction it is reduced 4 times to 500 RPM. The second reduction of 4:1 reduces it down to 125 RPM. The total reduction is the motor speed of 2000 RPM divided by the final speed of 125 or 16. A gear ratio is the ratio used to determine the angular speed and torque of a geared system.

Answer:
An example of zymogen is pepsinogen. Pepsinogen is the precursor of pepsin. Pepsinogen is inactive until it is released by chief cells into HCl. The latter partially activates pepsinogen. Pepsinogen will be fully converted into pepsin when an inhibiting peptide unit is removed.
