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. Biodiversity is important for healthy ecosystems because it:

Correct answer: B

Rationale: Rationale: Biodiversity refers to the variety of living organisms in a particular area. A diverse ecosystem is better able to withstand and recover from disturbances such as natural disasters, climate change, or human impacts. This is because different species play unique roles in the ecosystem, and a higher level of biodiversity means there are more species available to fulfill these roles. For example, if one species is negatively affected by a disturbance, other species may be able to compensate for its loss, maintaining the overall functioning of the ecosystem. Therefore, biodiversity provides stability and resilience to disturbances, making ecosystems healthier and more sustainable.

3. Which type of nuclear force is responsible for holding protons and neutrons together in the nucleus of an atom?

Correct answer: C

Rationale: The incredibly powerful, strong nuclear force overcomes the repulsive electrostatic force between protons, binding them together and stabilizing the nucleus.

4. Which type of waves do not require a medium for propagation?

Correct answer: c

Rationale: Electromagnetic waves (such as light or radio waves) can travel through a vacuum as they do not require a medium.

5. What is the name of the wart-like growths caused by the human papillomavirus (HPV)?

Correct answer: C

Rationale: The correct answer is C: 'Papillomas.' Wart-like growths caused by the human papillomavirus (HPV) are known as papillomas. Keloids are raised scars that occur at the site of skin injury, while carcinomas are cancerous tumors. It is important to differentiate between these terms to accurately describe the specific condition caused by HPV. Papillomas can vary in appearance and may be found on the skin, genital area, or inside the mouth and throat.

6. What happens when an atom loses an electron?

Correct answer: B

Rationale: It gains a positive charge and becomes an ion. Losing an electron disrupts the charge balance, leaving the atom with more protons than electrons and a positive charge.
