Biology

1. What is the building block of RNA?

Correct answer: B

Rationale: Rationale: A) Amino acid: Amino acids are the building blocks of proteins, not RNA. B) Nucleotide: Nucleotides are the building blocks of RNA. A nucleotide consists of a nitrogenous base (adenine, guanine, cytosine, or uracil in RNA), a sugar (ribose in RNA), and a phosphate group. C) Protein: Proteins are made up of amino acids, not nucleotides. D) Fatty acid: Fatty acids are components of lipids, not RNA.

2. Which organ is responsible for filtering blood and removing waste products?

Correct answer: B

Rationale: The correct answer is B: Kidneys. The kidneys are responsible for filtering blood and removing waste products from the body through the production of urine. The liver plays a role in detoxifying the blood and producing bile, while the spleen is involved in filtering blood and removing old or damaged red blood cells. The pancreas is primarily responsible for producing digestive enzymes and regulating blood sugar levels. Therefore, the kidneys are the specific organ dedicated to the filtration of blood and removal of waste products, making them the correct choice in this question.

3. Which organ helps break down food by grinding it with your teeth?

Correct answer: D

Rationale: Rationale: The mouth is the organ that helps break down food by grinding it with your teeth. The process of chewing, also known as mastication, breaks down food into smaller pieces, making it easier to swallow and digest. The teeth in the mouth play a crucial role in this initial stage of digestion by physically breaking down food into smaller particles. The other options listed do not directly participate in the mechanical breakdown of food through chewing.

4. An Egyptian model pyramid has a square base side length of 10cm and a height of 8cm. What is its volume?

Correct answer: D

Rationale: Use the formula for volume of a pyramid: (1/3) * base area * height. Calculate the base area (10cm * 10cm = 100 sq cm) and substitute: (1/3) * 100 sq cm * 8cm = 80 cu cm.

5. Which energy conversion occurs in a solar cell?

Correct answer: d

Rationale: Solar cells convert solar energy (sunlight) directly into electrical energy.

6. Muscles that work in opposition to each other, producing opposing movements, are called:

Correct answer: B

Rationale: The correct answer is B: 'Antagonists.' Antagonistic muscles are pairs of muscles that work in opposition to each other to produce opposing movements around a joint. For example, the biceps and triceps in the arm act as antagonists - when the biceps contract to bend the elbow, the triceps relax, and vice versa. Synergists (A) are muscles that work together to create a movement, agonists (C) are primary muscles responsible for generating movement, and fixators (D) are muscles that stabilize joints to allow other movements to occur. Understanding the roles of antagonistic muscles is crucial in biomechanics and exercise science.
