Answer:minerals
Explanation:
Chemicals are the smallest level of organization that makes the cell. The nucleic acids, water, and carbohydrates are crucial for life, but minerals are not chemicals of life. Thus, option A is correct.
What are biochemicals?Biochemicals are substances that are essential for living things and are also produced inside the cells. Major biochemicals are carbohydrates, nucleic acids, lipids, and proteins. They are made up of various chemicals and elements.
These are the most essential chemicals that are crucial for survival and play an important role in various activities and functions. Minerals are not chemicals involved in life. The various chemicals perform various metabolic and cellular functions.
Thus, option A. minerals are not chemicals of life.

How do you change a solid into a liquid?
Answer:
you melt it
Explanation:
You change a solid to a liquid by melting it.
for example ice becomes a liquid by melting.
Answer:
Heat is probably the easiest energy you can use to change your physical state. The atoms in a liquid have more energy than the atoms in a solid. There is a special temperature for every substance called the melting point. When a solid reaches the temperature of its melting point, it can become a liquid.

An unknown solid is placed on a scale and has a mass of 2.5 grams. The solid then displaces 35 mL of water in a graduated cylinder. Find the unknown solid’s density.
Answer:
The unknown solid’s density is 0.071 [tex]\frac{g}{mL}[/tex]
Explanation:
Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space. In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
[tex]density=\frac{mass}{volume}[/tex]
From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.
Archimedes' principle states that every body immersed in a fluid experiences a vertical and upward thrust equal to the weight of fluid dislodged. In other words, this principle says that the volume of the object is equal to the volume of the water displaced or displaced. So:
mass= 2.5 gramsvolume=35 mLReplacing in the definition of density:
[tex]density=\frac{2.5 g}{35 mL}[/tex]
you get:
[tex]density=0.071\frac{g}{mL}\[/tex]
The unknown solid’s density is 0.071 [tex]\frac{g}{mL}[/tex]
Answer: The answer would be 0.071 g/cm^3

225 mm=_____hm
this is a 2-step problem
To find how many hectometers this is, we can divide the amount by 100,000.
225 / 100000 = 0.00225
Therefore, 225mm = 0.00225hm

What is the volume of 88.2 g of silver metal (density = 10.50 g/cm^3)
Answer:
The answer is
8.4 mLExplanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} [/tex]
From the question
mass = 88.2 g
density = 10.5 g/cm³
The volume is
[tex]volume = \frac{88.2}{10.5} [/tex]
We have the final answer as
8.4 mLHope this helps you
