This man is credited with the creation of the modern Periodic Table.
Mendeleev
An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This is apart of Newton's First Law of Motion which is also considered to be the _____________________.
Law of Inertia
In terms of energy, what is the difference between glucose and ATP?
Glucose is a form of stored energy. ATP is a form of energy that cells can use directly
For how many integer values of b is b+3>0 and 1>2b-9?
Seven. b>-3, and b<5. Since b is an integer, b may be equal to any of the following: -2, -1, 0, 1, 2, 3, or 4.
If 1/3 of a number is 4 less than 1/2 of the number, the number is
24.
Let X represent the unknown number. Since 1/3 of x is 4 less than 1/2 of x, x/3=x/2-4. So, 2x=3x-24, giving x=24
