Biology
1 answer:
kipiarov [429]3 years ago

Gases in Earth's Atmosphere. Nitrogen and Oxygen are by far the most common. Dry air is composed of about 78% Nitrogen (N2) and about 21% Oxygen (O2). Argon, Carbon Dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere's mixture of gases.

So therefore Oxygen is the gas that makes up the largest portion of the Earths Atmosphere.

A dog experiencing a high level of fear will usually exhibit
Cerrena [4.2K]
I believe the correct answer is D. <span>ears pinned back, eyes averted or lowered, and lips pulled back and down.
When dogs are afraid, their ears are lowered to show fear because of something they may have done wrong. They are also scared or embarrassed to look at their owner because they know they will receive some sort of punishment. Their tail is also usually tucked between their legs to show they are afraid.

A jar contains 26 fluid ouncesbof spaghetti sauce. How many cups of spaghetti sauce do 4 jars contain
JulijaS [17]

____________________________________________________

Answer:

Your answer would be 13 cups of spaghetti sauce.

____________________________________________________

Explanation:

Lets break down this question to make the answer easier:

8 ounces = 1 cup

We are going to use the above to help us solve this question.

In your question, you have 26 ounces, and you would have four cups. You would need to calculate how many ounces are in the 4 cups

To do this, you would multiply 26 by 4:

26 × 4 = 104

The four cups have a total of 104 for ounces. But, you are not done solving yet. You need to found how many cups there are. We would be going to use the 8 ounces, since we know that is the amount of one cup, and use that to divide 104, since we need to distribute the amount of ounces to the cups.

You would divide 104 by 8

104 ÷ 8 = 13

There would be 13 cups of spaghetti sauce in 4 jars of spaghetti sauce that has 26 ounches in it.

Your FINAL answer would be 13.
