lSince the level of CFCs did not significantly decrease after 1990, CFCs will contribute to the current increase in global warming
<h3>What are greenhouse gases?</h3>
Greenhouse gases are those gases which contribute to the increase in global warming due to their property of preventing heat energy escape from the earth.
CFCs are greenhouse gases.
Therefore, if the level of CFCs did not significantly decrease after 1990, CFCs will contribute to the current increase in global warming.

Not every gene has a dominant or recessive form. Each allele in the gene pair may occasionally carry equal weight and manifest as a composite physical trait.
<h3>Why are genes so important?</h3>
The building blocks of life are genes. They include instructions for constructing particular molecules and proteins that control how the body develops and functions and enable human cells to function. Additionally, they influence how certain physical traits and attributes, like hair or eye color, are expressed.
<h3>How are genes created?</h3>
One copy is passed down to them by their mother through the egg, while the other is passed down by their father (via the sperm). The 23 chromosomes in each egg and sperm are all found in one pair. When the sperm fertilizes the egg, two copies of each chromosome and two copies of each gene are produced, resulting in the development of an embryo.

On number two of the second file, mass is how many atoms there are, while weight is how much he gravitational body the object is on (if any) pulls the object (which is why we weigh nothing in space).
For the first question of the second image, A's answer would be 1,800 g/300cm^3, or 600g/cm^3.
For B, .250g/cm^3 * 200cm^3 is 50g.
For the table: Density is how compact the matter of an object is in a certain amount of space. An example would be that water has a density of 1g/cm^3
Mass is how much matter there IS, for example, a car has more mass than an orange.
Volume is the quantity of 3d space an object has or how "big" it is. For example, a cubed building is the length of one side to the third power
Weight is how much gravity is pulling on an object, and not related to how much stuff an object has other than that, for example, you might weigh 100 kilograms on Earth but none is space, and your matter hasn't changed.
I hope you enjoyed your answer.
