Answer:
a) 0
Explanation:
Each of the small dots surrounding the C1 represents one electron. These are where electrivity comes from. Since there is the same number of electrons in both atoms, the difference is 0 (because 6 electrons-6electrons= 0).
Gas pressure is measured in mmHg with a barometer

Answer: D) all of the above</h3>
Explanation:
The lungs pump oxygen in and carbon dioxide out, which goes through the blood stream to help with the cell's energy needs.
Nutrients pass through the blood stream as well. The nutrients start with the digestive system (mouth, esophagus, stomach, small intestine) before going into the blood stream. The nutrients are building blocks to help make new cells when old ones die off.
When those cells die off, the body sheds them like dead skin, but internal dead cells are passed off as waste. This waste and other byproducts the body doesn't need passes through the blood stream as well.
In short, the blood stream is basically the highway to help get desired materials (eg: oxygen and nutrients) and get rid of waste (eg: carbon dioxide and other unwanted byproducts or dead cell material)
So that's why the answer includes A, B and C.
Answer:
The avocado consists of around 73% water, 15% fat, 8.5% carbohydrates — mostly fibers — and 2% protein. Half an avocado, at around 100 grams (g) contains 160 calories ( 1 ).
The answer is (3) carbon atoms. For 2-butanol, it contains single bonds only and with C, O, H atoms. For 2-butene, it contains single bonds and double bonds both. And contains C, H atoms.
