The difference between Argon-38 and Argon - 45 is the number of neurons in their nuclei.
<h3>
What is Isotope?</h3>
Isotopes are two or more types of atoms of the same element that have the same atomic number but differs in mass numbers due to different numbers of neutrons in their nuclei.
Argon atom with a mass number of 38 (Ar-38) - number of neutrons = 20
Argon atom with a mass number of 45 (Ar-45) - number of neutrons = 27
Thus, the difference between Argon-38 and Argon - 45 is the number of neurons in their nuclei.

When the particles of a substance (usually a liquid) is heated up, its particles absorb the energy provided thereby increasing their kinetic energy resulting to more movement of the individual particles.
Algae is not an abiotic factor.
The rate of the reaction is measurable quantity that refers to the amount or how much is are chemical substances reagents used up or converted into the product over some period of time.
Rate = change in the amount/time.
This can indirectly be observed through many ways, such as the volume of gas given off if the byproduct is a gas being produced, the colour of the solution etc.
Answer:
+/- 0.00033
Explanation:
For a 95 % confidence interval the range is given by
+/- Z * s/sqrt(n)
where Z value is 1.916 for a 95% confidence interval
Therefore the interval is
s is the standard deviation in this case 0.0015
n is 75 the number of outposts
calculating,
+/- 1.916 * 0.0015/sqrt(75) = +/- 0.00033
