dedylja [7]

Answer:

0.004 m/yr.

Explanation:

Hello!

In this case, since the velocity of any object is computed by dividing the travelled distance by the elapsed time, we obtain:

V=\frac{distance}{time}\\\\V=\frac{100,000m}{25,000,000yr}\\\\V=0.004m/yr

It means that the plate moves 0.004 m every year.

Best regards!

How does the digestive system interact with the rest of the body
Ainat [17]

Answer:

The Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go. It Filters out waste from food and pushes it through intestines and out the body.

Explanation:

As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.
