ATI TEAS 7 Science Questions

Question 1 of 5

Which of the following nucleic acids carries amino acids to organelles called ribosomes, where the amino acids are linked one by one to produce a polypeptide?

Correct Answer: D

Rationale: The correct answer is D: tRNA. Transfer RNA (tRNA) carries amino acids to ribosomes during protein synthesis. tRNA has an anticodon that pairs with the mRNA codon, ensuring the correct amino acid is added to the growing polypeptide chain. A: DNA carries genetic information but does not directly participate in protein synthesis. B: mRNA carries the genetic information from DNA to the ribosomes but does not carry amino acids. C: rRNA is a structural component of ribosomes and helps in protein synthesis but does not carry amino acids to the ribosomes.

Question 2 of 5

What is the name of the condition characterized by swelling caused by a buildup of lymph fluid?

Correct Answer: B

Rationale: The correct answer is B: Edema. Edema is the condition characterized by swelling caused by a buildup of lymph fluid. Lymph fluid can accumulate in tissues due to various reasons such as lymphatic system blockages or underlying medical conditions. Anemia (A) is a condition characterized by a deficiency of red blood cells or hemoglobin. Hypertension (C) is high blood pressure, not related to lymph fluid buildup. Diabetes (D) is a metabolic disorder affecting blood sugar levels, not directly related to lymph fluid accumulation. In this case, edema is the most appropriate choice as it specifically addresses the swelling caused by lymph fluid buildup.

Question 3 of 5

Dysentery is an infectious disease caused by which type of microbe?

Correct Answer: B

Rationale: The correct answer is B: Bacteria. Dysentery is primarily caused by pathogenic bacteria such as Shigella or Escherichia coli. Bacteria are single-celled microorganisms that can infect the intestines and cause symptoms like bloody diarrhea and abdominal pain. Helminths are parasitic worms that typically cause different types of infections. Protozoa are single-celled organisms that can also cause intestinal infections, but they are not the primary cause of dysentery. Fungi do not typically cause dysentery; they are more commonly associated with skin infections or respiratory issues. In summary, the correct answer is B because dysentery is most commonly caused by bacterial infections in the intestines.

Question 4 of 5

Which part of the nervous system is responsible for transmitting signals from the sensory organs to the central nervous system?

Correct Answer: C

Rationale: The correct answer is C: Peripheral nervous system. This system consists of nerves that connect the sensory organs (such as eyes, ears, skin) to the central nervous system (brain and spinal cord). It transmits sensory information from these organs to the CNS for processing. The autonomic nervous system (A) controls involuntary functions, somatic nervous system (B) controls voluntary movements, and central nervous system (D) processes and integrates information but does not directly transmit signals from sensory organs.

Question 5 of 5

What is the recommended daily fiber intake for adults?

Correct Answer: B

Rationale: The correct answer is B (25 grams) as the recommended daily fiber intake for adults by the American Heart Association is 25-30 grams. Fiber helps with digestion, heart health, and weight management. Option A (10 grams) is too low and insufficient for daily needs. Option C (35 grams) and D (50 grams) are excessive and may lead to digestive issues like bloating or gas. Therefore, B is the most appropriate choice for optimal health benefits.
