Air, water, and other organisms as a form of symbiotic relationships
Answer:
A. 0.0451
Explanation:
To determine the amount of significant figures in numbers in science, it is important to follow specific rules:
- A non-zero digit is significant. For example: 0.0211
- Zeros located between two significant numbers are significant. For example: 56.20006
- Trailing zeros in cases of the presence of a decimal point. For example: 434.9100
<em>Option A</em>. 0.0451 has <u>three significant figures</u>: 4, 5, 1.
<em>Option B</em>. 450 has t<u>wo significant figures</u>: 4, 5.
<em>Option C.</em> 32.10 has <u>four significant figures</u>: 3, 2, 1, 0.
Option D. 370.0 has <u>four significant figures</u>: 3, 7, 0, 0.
Therefore, option A. 0.0451 is the correct answer.
Most likely the correct answer among the choices listed is option A. The absence of oxygen causes a switch from aerobic to anaerobic respiration. Aerobic respiration requires oxygen to occur while anaerobic respiration do not.
Answer:
Sound travels fastest through the SOLIDS
Explanation:
Since the density of solids is high and the molecules of a solid are closely packed, sound waves are quickly transmitted from one molecule to the next thus enabling it to travel faster. The speed of sound, therefore, is fastest in solids, followed by liquids (less dense than solids) and then gas (least dense).
