I would say keep the soil from eroding and doesn't let it get dried out so fast.
QUESTION:-
What is the maximum number of electrons that can be placed in the first shell/energy level?
A. 1
B. 8
C. 2
D. 18
Answer:
C. 2
The first shell, closest to the nucleus and with the lowest-energy electrons, is shell 1. This first shell has only one subshell (labeled 1s) and can hold a maximum of 2 electrons
Answer:
Because the English measurement system has been in use for a very long time, it will be costly and time consuming to change from the English to SI units. Many technological measurements, products, and tools were developed in English units.
The cost of converting all measurements to SI units will be costly and will require a long period of time. Conversions between the English and the SI system of units appear to be more cost-effective than hardware changes.
Example:
It will be costly to convert designs for bridges, tunnels, locomotives, automobiles, and other hardware to the SI system. Although new designs are being performed in SI units, much useful hardware based on English units still remain.
Eventually, it is likely that complete conversion from English to SI units will happen, albeit slowly.

Answer:
corrugated cardboard tube - digestive tract
irregular surfaces on the corrugated tube - villi
pump - heart
Plastic tubing - blood vessels
Explanation:
The corrugated cardboard tube represents the digestive tract. The give away was the presence of the irregular surfaces within the tubes. This is called the villi. The villi is responsible for the absorption of food after digestion into the body.
Irregular surfaces on the corrugated tube represent the villi. They are tiny hair-like structures that are in the small intestine, that are responsible for the absorption of food into the bloodstream.
The pump represents the heart. The heart is the only organ in the body that provides the pressure force that pushes the blood throughout the body. In this model, the pump will most likely be performing the same function.
The plastic tubings are meant to contain one form of fluid or the other. Judging from that, they can be said to represent the blood vessels. This is because they are connected to the heart and are meant to transport bodily fluids around the body
