Exam 1 Retake - A&P 101

• Question 1: Centrioles are rod-shaped structures made of fine tubes, critical for cell division, not ribosomes, mitochondria, or Golgi apparatus.

• Question 2: Cilia are small, hair-like structures on the exposed surface of some cells, not nucleus, nucleolus, or endoplasmic reticulum.

• Question 3: A sagittal section divides the body into right and left portions, not a frontal, transverse, or coronal section.

• Question 4: Matter is anything that occupies space and has mass. (True)

• Question 5: Prone position places the dorsal (back) side of the body on the ground, not ventral (belly). (False)

• Question 6: Distal is the opposite of proximal, not medial, superior, or anterior.

• Question 7: Knee is distal to the ankle, not inferior, medial, or proximal.

• Question 8: Water diffusing through a selectively permeable membrane is osmosis, not dialysis, filtration, or pinocytosis.

• Question 9: Dissection is the process of cutting apart to study, not physiology, homeostasis, or anatomy.

• Question 10: A base has a pH above 7 and more OH⁻ ions than H⁺ ions, not less than 7 or having fewer OH⁻ ions.

• Question 11: The word leg refers only to the portion between the knee and ankle. (False)

• Question 12: Endoplasmic reticulum is a network of canals, not flagella, Golgi apparatus, or lysosomes.

• Question 13: Nucleus controls most cellular activities, not the cilia, nucleolus, or ribosome.

• Question 14: Thoracic cavity is divided into 2 parts: the mediastinum and the pleural cavity, not the dorsal cavity. (False)

• Question 15: A blood pH of 7.28 indicates an excess of H+, not normal pH, alkalotic, or deficient acid.

• Question 16: The heart is medial to the lungs, not distal, lateral, or proximal.

• Question 17: The opposite of medial is lateral, not dorsal, superficial, or proximal.

• Question 18: Water diffuses from the lower concentration solution 50%, (compartment B) to the higher concentration solution (compartment A), water in compartment A will be less than compartment B.

• Question 19: Atomic number = number of protons. In this question, 16 protons = 16 atomic number.

• Question 20: Compounds are formed from two or more different types of atoms, not pure substances, one type of atom, or 96% of human body.

• Question 21: Spinal cavity is part of the dorsal cavity, not ventral, cranial, or thoracic cavity.

• Question 22: Atomic mass is the sum of protons and neutrons.

• Question 23: Proton carries a positive electrical charge. (True)

• Question 24: Electrons are found in orbitals around the nucleus of the atom, not neutrons, protons, or both.

• Question 25: Brain is in the cranial cavity, not ventral, mediastinum, or thoracic cavity.

• Question 26: An acid has a pH less than 7, not greater than 7, more OH⁻ ions or neutral.

• Question 27: Physiology studies the body's functions, not homeostasis, anatomy, or dissection.

• Question 28: Atomic mass is the sum of protons and neutrons. 16 protons + 17 neutrons= 33.

• Question 29: Lysosomes are bag-like structures containing digestive enzymes (True).

• Question 30: Atomic number is equal to the number of protons.

• Question 31: Subatomic particles found in the nucleus are protons.

• Question 32: A cut dividing the body into upper and lower portions i a transverse section.

• Question 33: Isotopes have the same number of protons but different numbers of neutrons.

• Question 34: If an atom has 20 protons and 18 electrons it has a +2 charge, not a -2 or be attracted to a positive charge but an opposite.

• Question 35: Low blood pH leads to acidosis, not alkalosis, atherosclerosis, or hydrolysis.

• Question 36: ATP is an energy transfer molecule, not a buffer.

• Question 37: Acids produce excess H+ ions. (True)

• Question 38: In an isotonic solution there is no net movement of water in or out of the cell.

• Question 39: Aqueous solutions use water as a solvent (True).

• Question 40: Mitochondria are the "power plants" of the cell, not ribosomes, Golgi apparatus, or centrioles.

• Question 41: Lungs are found in the thoracic cavity.

• Question 42: Covalent bonds form when electrons are shared between atoms.

• Question 43: O₂ = made up of two oxygen atoms.

• Question 44: Neutrons have no electrical charge. (True)

• Question 45: Mediastimum is within the ventral cavity.

• Question 46: Frontal section = anterior and posterior portions.

• Question 47: Hemolysis is defined as bursting of red blood cells.

• Question 48: A Hypertonic solution causes a crenation (or shrinkage) of red blood cells.

• Question 49: Water initially diffuses from the compartment with lower concentration to higher, in this case compartment B to compartment A.

• Question 50: A increase in H+ will decrease pH. (False)
