Correct answer choice is:
<h2>D. They are each made of matter. Some are compounds made of one type of element. Some are pure atoms.</h2><h3>Explanation:</h3>
The matter is a substance that has inertia and holds bodily area. According to advanced physics, matter consists of several kinds of particles, each with volume and area.
A pure element indicates a substance whose atoms possess the equivalent atomic number or number of protons.
Silver is extensively utilized as a manufacturing catalyst for the composition of ethylene epoxide via ethylene oxidation and for formaldehyde via methanol oxidation. Oxygen classes on silver are determined to perform a pivotal use in ethylene epoxidation and particular methanol oxidation.
The outcome of the reaction between hydrogen gas and oxygen gas is water vapor (gas).
Water and carbon dioxide are compounds composed of various elements, whereas, silver and oxygen remain pure elements.
Plants, microorganisms, and animals
Answer:
C. The moon's gravitational pull and Earth's rotation
Explanation:
The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.

Hairpin like structures are formed in both DNA and RNA but are common in RNA than in DNA. This is because DNA can be double stranded or single stranded while RNA is generally single stranded structure that can be double stranded only when it forms a hair pin like structure.
The features of hairpin structure in RNA are as follows:
1. This structure is a building block of many secondary structures of RNA.
2. The termination sequence during transcription also forms a hairpin loop like structure.
3. tRNA also forms a hairpin loop like structure and helps in the process of translation.
