There is a basic difference, because mass is the actual amount of material contained in a body and is measured in kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg. Note that mass is independent of everything but weight is different on the earth, moon, etc.
Answer: circle graph.
Justification:
A circle graph (also known as pie chart) is excellent to visualize the relative size of different sectors. Being the entire circle 100%, each sector will show the percent of each category.
In the given example, the circle will be divided in 3 different sectors, in which the size is proportional to the percent of each one.
In the given case::
<span>pH less than 8: 20%
</span><span>
</span><span> pH between 8 and 8.5: 50%,
</span><span>
</span><span>pH greater than 8.5: 30%
</span><span>
</span><span>
</span><span>So, a sector whose area is 20% will represent the first category, a sector whose area is 50% will represent the second category, and a sector whose area is 30% will represent the third category. The whole circle is 100%, this is the sum of the 3 categories is 100%.

Answer:
the law says the temperature difference between two objects falls exponentially.
doesn't change in time and no heating or cooling would happen.
> How many valence electrons does a helium atom have?
The electron configuration of Helium is simply 1s2. We see
that its outermost shell is the s shell and it contains 2 electrons, therefore
the number of valence electrons is also 2.
> What is the formula of the ion formed when potassium
achieves noble-gas electron configuration?
Potassium has a electron configuration of [Ar] 4s1. To
have an electron configuration of only [Ar] which is a noble gas, the one electron
from 4s1 should be removed, hence:

Answer:
18 molecules of ATP will be produced for the breakdown of methionine to succinyl CoA and the entry of succinyl CoA to the citric acid cycle with no input of glucose.
Explanation:
Reactions reduced co enzymes ATP formation
α keto glutarate to propionyl CoA 2 NADH 6 moles
Succinyl CoA to succinate 2 GTP≈ 2 ATP
Succinate to fumarate 2FADH2 4 moles
Malate to oxaloacetate 2 NADH 6 moles
