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.
The answer is B. hope this helps I have an 86.6 in biology.
<span>An ecosystem<span> consists of a community of organisms together with their physical environment.
</span><span>Ecosystems can be of different sizes and can be marine, aquatic, or terrestrial. Broad categories of terrestrial ecosystems are called </span>biomes.
In an ecosystem, both matter and energy are conserved. Energy flows through the system—usually from light to heat—while matter is recycled.

Answer:
The correct answer will be option-E.
Explanation:
The CRISPR-Cas9 system is a simple and most versatile genome-editing tool to edit the genome of an organism.
The system consists of two components: "Cas-9 enzyme" which act like molecular scissors to cut the DNA and "Guide RNA or gRNA" which guides the Cas-9 enzyme to the target DNA by binding to the target DNA.
The gRNA consists of 20 bases long RNA sequence which is complementary to the sequence of the target DNA. This binding ensures the right binding and cutting of the target DNA.
Thus, option-E is the correct answer.
