Pathogens can be transmitted through contact with surfaces like doorknobs and countertops.a. True
b. False

Answers

The answer is a. True.

Some pathogens can be transmitted through direct contact with infected person, and some pathogens can be spread through contact with surfaces like doorknobs and countertops. For example, an infected person can touch these surfaces and leave behind pathogens. When an uninfected person touches the surfaces and then touches its skin, the pathogens are transmitted to that person. Staphylococci are the commonly transmitted this way.

_____ allow materials to be exchanged between the blood and tissues, _____ carry blood towards the heart, and _____ carry blood away from the heart.

Answers

Capillaries; veins; arteries

Capillaries allow materials to be exchanged between the blood and tissues, veins carry blood towards the heart, and arteries carry blood away from the heart.

Capillaries are small blood vessels through which molecules such as oxygen and glucose enter the cells.

Veins are tubes or blood vessels that transport blood toward the heart. Veins mostly transport deoxygenated blood towards the heart except the pulmonary and umbilical veins, which transports oxygenated blood toward heart.

Arteries are blood vessels that transport blood away from the heart to other parts of the body. Arteries have elastic walls and they are stronger and thicker than veins.

Chemistry: counting atoms in compounds worksheet #7.0.1
Answer please!!!!!

Answers

Atom is the most basic unit of matter. They are the general term used to describe pieces of matter. But a different kind of atom makes up an element. A combination of atom of different elements creates a molecule. For example, you have water; it has a chemical formula of H2O. If you separate H from O, you have two atoms. Two atoms for hydrogen and one atom for oxygen. However, they are of different elements. And when you combine them to form H2O, you create a molecule.

In the given query, the total number of atoms present in the given chemical compound $\rm KMnO_4$ is six atoms total in number.

Compounds were formed when two atoms combine together by sharing electrons among themselves.

In the compound $\rm KMnO_4$ : It contains 1 K (Potassium atom), 1 Mn (Manganese atom) and 4O (Oxygen atom).

That means the compound contains total of six atoms in it.

Therefore, there are six atoms total in number present in the given compound $\rm KMnO_4$ .
