Correct Answer: C

Rationale: The tonsils and adenoids are lymphatic tissues located in the head and neck region, specifically in the throat area. They are essential components of the immune system, acting as the first line of defense against infections that can enter through the nose and mouth. The tonsils are situated at the back of the throat, while the adenoids are positioned high in the throat behind the nose.

Choices A, B, and D are incorrect as they do not correspond to the anatomical location of the tonsils and adenoids.
Therefore, the correct answer is the head and neck region.

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 (GER
D) 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.

Correct Answer: A

Rationale: The table is much heavier than the book, so it requires a much larger force to accelerate it. The book is lighter and easier to move, so the force applied to it causes it to move without significantly affecting the table due to the table's greater mass. Newton's third law states that for every action, there is an equal and opposite reaction. In this case, the force exerted on the book by the table is countered by an equal force exerted on the table by the book, but the table's greater mass resists movement.
Choice B is incorrect because the forces are equal and opposite, acting in the same direction.
Choice C is incorrect as the surface area does not affect the movement of the table in this scenario.
Therefore, the correct answer is A, as the table's greater mass prevents it from moving easily when a force is applied.

Correct Answer: A

Rationale: In physics, the term 'net force' refers to the total force acting on an object, considering all individual forces acting on it. It is crucial in determining the object's motion and acceleration as it represents the overall force applied to the object.
Choice B, 'Force due to gravity,' is incorrect as it refers to a specific force acting on an object due to gravity.
Choice C, 'Force in motion,' is incorrect as it does not define the concept of net force.
Choice D, 'Force of friction,' is incorrect as it specifically refers to the force opposing motion when two surfaces are in contact.

Correct Answer: B

Rationale: - Genotype refers to the genetic makeup of an organism, including all the genes and alleles it possesses.
- Phenotype, on the other hand, refers to the observable physical characteristics or traits of an organism, which result from the interaction between its genotype and the environment.
- While genotype represents the genetic potential or range of traits that an organism can express, phenotype reflects the actual expression of specific traits.
-
Therefore, option B correctly captures the distinction between genotype and phenotype in the context of gene expression.
