Assuming you mean 7m^3 (meters cubed) of Sand:
Volume = base x width x height
The truck can hold a volume of 2.5 x 1.5 x 1 = 3.75 m^3.
To move 7 m^3 of sand, the truck will have the make two trips. The first trip, the truck will move 3.75 m^3 of sand, and on the second, it will move 7-3.75=3.25 m^3.
On the Galapagos Islands, Darwin also saw several different types of finch, a different species on each island. ... Finches that ate small nuts and seeds had beaks for cracking nuts and seeds. Darwin noticed that fruit-eating finches had parrot-like beaks, and that finches that ate insects had narrow, prying beaks.
Answer:
a biological catalyst which speeds up reactions without being used up
Explanation:
Answer:
Option b.) propulsion: physical breakdown of ingested food in the GI tract
Explanation:
The physical breakdown of ingested food in the GI tract is called Mechanical digestion, and it breaks the food into smaller parts, to have more surface area for digestion, also to increase mobility. An example of Propulsion is the act of swallowing, which objective is to move the food through the digestive tract.
The correct order of functions is: Ingestion, Propulsion, Mechanical digestion, chemical digestion and Absorption.
A substance that speeds up the rate of a chemical reaction is called a Catalyst.
