Answer:
They can use these printers to make replica or identical copies of things like fossils. Theses are mostly useful because real fossils are rare so they can still study them without possibly ruining an artifact.

Explanation:
The rock cycle has 5 main sections (igneous, sedimentary, sediment, metamorphic, and magma.) The rock cycle can go almost any way it wants. Its not like the water cycle were it goes in certain order.
Answer:
The answer is 306 m/s^2
Explanation:
F = m*a
We can rearrange this formula to get a = F / m.
The SI unit for mass is kilograms (kg).
The SI unit for acceleration is m/s^2.
There are 1000 grams in a kilogram.
7.20 g = 0.00720 kg
Force (2.20 N) / 0.00720 kg = 305.56 m/s^2
Accounting for Sig Figs, the answer is 306 m/s^2.
Gee, that's one fast bullet.
Explanation: because carry out all the functions in the human body necessary for living. Proteins make up hormones that are required for living. Insulin - responsible for stabilising blood sugar. Haemoglobin - responsible for carrying oxygen around the body. Melatonin - responsible for helping us get to sleep. Adrenalin - responsible for the flight-fight-freeze response. There are many more but here are just a few.
