Answer:
veins and arteries
Explanation:
veins carry deoxygenated blood from the cells in the body to the heart and arteries vice versa
The circulatory system consists of veins and arteries which circulate blood from the heart to the lungs to get oxygen. The arteries carry oxygenated blood to the rest of the body from the heart. The veins bring oxygen-depleted blood back to the heart, where it is circulated again.
The blood gets oxygenated in the lungs. The arteries which carry oxygenated blood from the lungs to the body parts is known as the pulmonary artery. It enters the heart through the left atrium. The left ventricle then pumps the blood through the aortic valve into the aorta.

If a substance weighs 2.00 grams and you need the mass in kilograms, will the number appear to become smaller or larger?
Answer:
The number will appear smaller
Explanation:
Grams and Kilograms are two units of measuring the weight of substances. These two units are interchangeable/interconvertible.
One kilograms of a substance contains 1000 grams of that substance (kilo=thousand). Hence, for a substance weighing 2.00grams whose weight measurement is needed in kilograms, it will be converted by dividing the weight in grams by 1000.
That is, 2.00g/1000 = 0.002kilograms or 2.00 × 10^-3kg. According to the number after conversion, it appeared SMALLER because the kilograms (kg) is a bigger measurement compared to the grams (g).

What is organic compounds?Any of a vast group of chemical compounds known as organic compounds contain one or more carbon atoms that are covalently connected to atoms of other elements, most frequently hydrogen, oxygen, or nitrogen.
Carbides, carbonates, and cyanides are among the few carbon-containing substances that aren't categorised as organic.
Covalently bound carbon and hydrogen, as well as frequently other elements, are found in organic molecules.
An inorganic compound in chemistry is often one that does not contain carbon-hydrogen bonds, i.e., one that is not an organic compound.
Inorganic chemistry is a branch of chemistry that focuses on the study of inorganic substances.
