HESI A2 V2 BIOLOGY Exam 2023/2024 Questions with Correct Answers.
HESI A2 V2 BIOLOGY Exam 2023/2024 Questions with Correct Answers A patient receives an antibiotic for symptoms of the flu. Why doesn’t the medication w ork? The medication is for a different type of flu. The medication is not suitable for treating the flu. The medication is not a strong enough dosage amount to cure the patient. None of the above The correct answer is B. Antibiotics are used for treating bacterial infections, but the flu is caused by a virus. Although symptoms can be similar in case of a cold (bacteria) or the flu (virus), viruses cannot be treated using antibiotics. The nucleus is important in a cell because: It stores the DNA It supports the cell It makes protein It makes energy out of food The correct answer is A. The nucleus is the “brain” of the cell and stores the DNA. A cell wall supports the cell (only if it is a plant). The ribosomes make protein and the mitochondria makes energy. Cellular respiration happens so that Cells can copy DNA Cells can breathe Cells can convert nutrients to energy Cells can divide The correct answer is C. The term respiration typically triggers thoughts of breathing, but in this case, it is referring to the process about:blank 2/31 cells undergo to convert nutrients into ATP. Copying DNA is transcription and translation. Cells themselves cannot breathe. Cell division is mitosis or meiosis, depending on the type of cell. Anaerobic respiration happens in Animals; they need energy Plants; they use sunlight _ because _ . Bacteria; they live in environments with low oxygen. None of the above The correct answer is C. Animals and plants both use aerobic respiration because they have access to oxygen. Bacteria typically live in environments with little to no oxygen and must still produce energy to survive. All bacteria are bad and always cause infections. True False The correct answer is B. Bacteria can be good, such as the bacteria in the intestines. This bacterium can become problematic if it travels to a location other than where it belongs. Pathogenic bacteria are bad and can cause infections, but not all bacteria are this type. about:blank 3/31 Which of the following is not true about antibiotics? They can interfere with the bacteria’s ability to survive They can affect how bacteria multiply They can cause more bacteria to grow They only work on bacteria The correct answer is C. Antibiotics only work on bacteria by either blocking its ability to grow or multiply, or completely killing the bacteria cells. Prokaryotic cells: Have a nucleus Have a capsule Have membrane bound organelles Cannot move on their own The correct answer is B. Prokaryotic cells are simple, single celled organisms. They do not have a nucleus or membrane bound organelles. This type of cell can move on its own with a flagella or small hair-like fibers. Select the cell parts that are present in plant cells but not animal cells (there may be more than one answer): Cell membrane Cell wall Ribosome Chloroplast The correct answer is B and D. Both plant and animal cells have a cell membrane and ribosomes, however only plant cells have a cell wall and chloroplasts. The cell wall is necessary for maintaining the shape and structure of the plant. Chloroplasts are necessary for photosynthesis. Epithelial tissue can be found in: Organ lining Heart muscle Tendons Spinal cord about:blank 4/31 The correct answer is A. Epithelial tissue is found in skin and all of the linings within the body. Heart muscle is muscle tissue, tendons are connective tissue and the spinal cord is nervous tissue. What are the three types of muscle tissue? Cardiac, spinal, stomach Smooth, skeletal, cardiac Neuron, epithelial, collagen None of the above The correct answer is B. Smooth muscle is found in organs like the stomach, where it is involuntarily controlled. Skeletal muscle is found in voluntary muscles, like the bicep or quadriceps. Cardiac muscle is found only in the heart walls and works involuntarily to make the heart beat and pump blood. about:blank 5/31 Which type of tissue is fat? Connective Muscle Nervous Epithelial The correct answer is A. Fat is a type of loose connective tissue called adipose. Its job is to cushion organs. Fat is not made of muscle cells, neurons or epithelial cells. What type of cells have a cell membrane? Prokaryotic only Eukaryotic only Both prokaryotic and eukaryotic None of the above The correct answer is C. Cell membranes are present in all types of cells. Its purpose is to hold in the fluids and other components of the cell and protect against external substances and invaders. How is the plasma membrane arranged? In a single layer made of proteins In a double layer made of proteins In a single layer of phospholipids In a double layer of phospholipids The correct answer is D. The plasma membrane is made of a phospholipid bilayer that has two layers of phospholipids. The hydrophilic phosphate heads face the outside of the layers and the fatty acid tails face inward, since they are hydrophobic. The head of a phospholipid: Is water loving Is water fearing Is on the outer side of the layer Both A and C The correct answer is D. The phosphate head is on the outer part of the bilayer because it is hydrophilic, which means that it can be in contact with water and not react. . . . . . . . . .
