ATI TEAS 7 science review

1. Salts are formed by the reaction between:

Correct answer: B

Rationale: Salts are formed by the reaction between an acid and a base. This reaction is known as a neutralization reaction. In this reaction, the acid donates a proton (H+) to the base, resulting in the formation of water and a salt as the products. Choice A is incorrect because salts are not formed by the reaction of two acids. Choice C is incorrect as salts are not produced by the reaction of two bases. Choice D is incorrect because while salts can be formed from the reaction between a metal and a nonmetal, it is not the only way salts are produced.

2. Why is warming up before exercise important?

Correct answer: B

Rationale: Warming up before exercise is crucial to prevent muscle soreness. It helps by increasing blood flow to the muscles, improving flexibility, and preparing the body for physical activity. Dehydration, increased heart rate, and low blood sugar are not directly prevented by warming up before exercise. Dehydration is prevented by proper hydration before and during exercise; increased heart rate is a normal physiological response to exercise; and low blood sugar is managed through proper nutrition and timing of meals before physical activity.

3. Which of the following is NOT a symptom of asthma, a chronic respiratory condition?

Correct answer: D

Rationale: The correct answer is 'Fever.' Fever is not a symptom commonly associated with asthma. Asthma symptoms typically include wheezing, difficulty breathing, and chest tightness due to inflammation and narrowing of the airways. Fever is more commonly seen in conditions such as infections or inflammatory diseases rather than asthma. Choices A, B, and C are common symptoms of asthma and are related to the constriction and inflammation of the airways, leading to breathing difficulties and chest discomfort.

4. Which law of motion states that for every action, there is an equal and opposite reaction?

Correct answer: C

Rationale: The correct answer is Newton's Third Law of Motion. This law states that for every action, there is an equal and opposite reaction. It means that when one object exerts a force on a second object, the second object exerts an equal force in the opposite direction back on the first object. This fundamental law describes the relationship between the forces acting on two interacting objects. Newton's First Law (Choice A) is known as the law of inertia and states that an object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an external force. Newton's Second Law (Choice B) relates the force acting on an object to its mass and acceleration. The Law of Universal Gravitation (Choice D) describes the force of gravity between two objects with mass and the distance between them.

5. Which condition is characterized by inflammation of the inner lining of the stomach?

Correct answer: D

Rationale: Gastritis is the correct answer as it is characterized by inflammation of the inner lining of the stomach. This inflammation can be caused by various factors such as excessive alcohol consumption, prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs), infections, or autoimmune diseases. Symptoms of gastritis may include abdominal pain, nausea, vomiting, and loss of appetite. Gastroesophageal reflux disease (GERD) is incorrect because it involves the backflow of stomach acid into the esophagus, leading to symptoms like heartburn and regurgitation, not inflammation of the stomach lining. Diverticulitis refers to inflammation or infection of small pouches that can form in the walls of the colon, not the stomach. Ulcerative colitis is a type of inflammatory bowel disease characterized by inflammation and ulcers in the colon and rectum, not the stomach lining.
