TEAS version 7 quizlet science

1. Which hormone stimulates the release of pancreatic enzymes and bile?

Correct answer: C

Rationale: Cholecystokinin (CCK) is the correct answer. It is the hormone that stimulates the release of pancreatic enzymes and bile. CCK is released by the small intestine in response to the presence of fats and proteins in the duodenum, triggering the release of digestive enzymes and bile to aid in the digestion of fats and proteins. Gastrin (Choice A) primarily stimulates gastric acid secretion, not the release of pancreatic enzymes and bile. Insulin (Choice B) regulates blood sugar levels by promoting glucose uptake. Glucagon (Choice D) raises blood glucose levels by stimulating the breakdown of glycogen in the liver.

2. During embryonic development, all tissues originate from

Correct answer: D

Rationale: During embryonic development, all tissues originate from the three primary germ layers: ectoderm, mesoderm, and endoderm. These germ layers give rise to various tissues and organs in the developing embryo through a process called gastrulation. Epithelial, muscle, and connective tissues are derived from these germ layers during development. Therefore, choices A, B, and C are incorrect as tissues do not originate from a single type of tissue but rather from the embryonic germ layers which differentiate into various tissues and organs.

3. The Human Genome Project is a worldwide research project launched in 1990 to map the entire human genome. Although the Project was faced with the monumental challenge of analyzing tons of data, its objective was completed in 2003, two years ahead of its deadline. Which of the following inventions likely had the greatest impact on this project?

Correct answer: C

Rationale: The microprocessor, a key component of modern computers, played a crucial role in the success of the Human Genome Project. The ability of microprocessors to process vast amounts of data quickly and efficiently allowed scientists to analyze the massive amounts of genetic information generated by the project. This technological advancement significantly accelerated the pace of genome sequencing and data analysis, ultimately leading to the completion of the project ahead of schedule. Choices A, B, and D are incorrect. The sonogram is used for imaging in medical diagnostics, X-ray diffraction is a technique for studying the structure of materials at the atomic level, and Magnetic Resonance Imaging (MRI) is a medical imaging technique that uses magnetic fields and radio waves to produce detailed images of the body. While these inventions have their own importance in various fields, they did not have the same impact on the Human Genome Project as the microprocessor did.

4. Which of the following statements best describes Newton's first law of motion?

Correct answer: A

Rationale: Newton's first law of motion, also known as the law of inertia, states that an object in motion will remain in motion, and an object at rest will remain at rest unless acted upon by an external force. This principle highlights the concept of inertia, which is the tendency of objects to resist changes in their state of motion. Option A accurately captures this fundamental aspect of Newton's first law. Options B, C, and D describe Newton's second law, third law, and the relationship between force, acceleration, and mass, respectively. Therefore, options B, C, and D are incorrect as they pertain to different laws formulated by Newton.

5. What are the components of the female internal genitalia and their functions?

Correct answer: C

Rationale: The correct answer is C. The ovaries are responsible for producing eggs (ova) and hormones (estrogen and progesterone). They are essential for reproduction, including the release of eggs for fertilization and for regulating the menstrual cycle. The fallopian tubes, as mentioned in choice A, transport eggs from the ovaries to the uterus for potential fertilization. The vagina, described in choice B, serves as the birth canal and also connects the uterus to the external environment. The cervix, as stated in choice D, is the lower part of the uterus that connects it to the vagina and also plays a role in protecting the uterus from infections and serving as a passage for menstrual flow.
