What is the name of the process in which an atom loses or gains electrons to form an ion?

A. Ionization

B. Oxidation

C. Reduction

D. Isotopic decay

Answer Explanation:

Ionization is the process in which an atom loses or gains electrons to form an ion.

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

Choice B is not the best answer because oxidation refers to the loss of electrons from an atom or molecule.

Choice C is not the best answer because reduction refers to the gain of electrons by an atom or molecule.

Choice D is not the best answer because isotopic decay refers to the process in which an unstable atomic nucleus loses energy by emitting radiation

Therefore, the Correct Answer is A.

Q #1: Which type of bond is responsible for the unique properties of water and plays a crucial role in the structure of DNA and proteins?

A. Hydrogen bonds.

B. Covalent bonds.

C. Ionic bonds.

D. Van der Waals forces.

Answer Explanation

The correct answer is choice A. Hydrogen bonds.

Hydrogen bonds are responsible for the unique properties of water and play a crucial role in the structure of DNA and proteins.

Hydrogen bonds are weak electrostatic attractions between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom.

Choice B.

Covalent bonds is incorrect because covalent bonds are strong chemical bonds formed by the sharing of electrons between two atoms.

Choice C.

Ionic bonds is incorrect because ionic bonds are chemical bonds formed by the transfer of electrons from one atom to another, resulting in the formation of ions.

Choice D.

Van der Waals forces is incorrect because Van der Waals forces are weak intermolecular forces that arise from temporary dipoles induced in atoms or molecules.
Q #2: A patient with chronic renal failure is undergoing hemodialysis. What process allows for the removal of waste products and excess fluid from the patient's bloodstream during hemodialysis?

A. Active transport.

B. Osmosis

C. Diffusion

D. Facilitated diffusion.

Answer Explanation

Diffusion.

During hemodialysis, waste products and excess fluids are removed from the blood by diffusion 1.

Diffusion is a separation process in which particles that are dissolved in a solution are relocated from an area of higher concentration in the blood to an area of lower concentration in the dialysate.

Choice A.

Active transport is incorrect because active transport is a process that uses energy to move molecules against a concentration gradient.

Choice B.

Osmosis is incorrect because osmosis is the movement of water molecules across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration.

Choice D.

Facilitated diffusion is incorrect because facilitated diffusion is a process where molecules move down their concentration gradient with the help of carrier proteins.
Q #3: Which of the following statements about bacteria and archaea is true?

A. A. Bacteria have a true nucleus while archaea do not

B. B. Archaea reproduce by spores while some bacteria reproduce by fission.

C. C. Bacteria can perform photosynthesis while archaea cannot.

D. D. Archaeal and bacterial flagella are constructed similarly.

Answer Explanation

Bacteria can perform photosynthesis while archaea cannot. Many types of bacteria can generate oxygen from sunlight through photosynthesis, while archaea cannot perform this process.

Choice A is incorrect because neither bacteria nor archaea have a true nucleus. Both are prokaryotic organisms. Choice B is incorrect because archaea reproduce by fission, fragmentation, or budding, while bacteria can produce spores and divide sexually or asexually. Choice D is incorrect because archaeal and bacterial flagella are constructed differently.
