Biology

1. What cellular process ensures accurate transmission of genetic material during cell division?

Correct answer: A

Rationale: Rationale: A) Mitosis is the process by which somatic cells divide to produce two identical daughter cells. During mitosis, the genetic material is accurately replicated and distributed to ensure each daughter cell receives a complete set of chromosomes. This process is crucial for growth, repair, and maintenance of multicellular organisms. B) Meiosis is the type of cell division that occurs in germ cells to produce gametes (sperm and egg cells). While meiosis also involves the transmission of genetic material, it is specifically geared towards generating genetic diversity through recombination and reduction of chromosome number. C) Replication is the process of copying DNA to produce an identical copy. While replication is essential for cell division, it is not the specific process that ensures accurate transmission of genetic material during cell division. D) Transcription is the process by which genetic information in DNA is copied into RNA. Transcription is important for gene ex

2. A birdbath has a hemispherical bowl with a diameter of 30cm. What is its volume?

Correct answer: C

Rationale: Use half the formula for a sphere's volume: (2/3) * π * (radius)^3. Calculate the radius (15cm) and substitute: (2/3) * π * (15cm)^3 ≈ 2700 cu cm.

3. What property of matter remains constant regardless of changes in gravity?

Correct answer: a

Rationale: Mass is the measure of the amount of matter in an object and remains constant regardless of changes in gravity or location. It is an intrinsic property of matter.

4. The three main types of muscle tissue in the human body are:

Correct answer: A

Rationale: The correct answer is A: Smooth, cardiac, and voluntary skeletal. Smooth muscle is found in the walls of internal organs and blood vessels, cardiac muscle makes up the heart, and voluntary skeletal muscle is attached to the bones and responsible for movement. Choice B is incorrect because cardiac muscle is involuntary, not voluntary. Choice C is incorrect because smooth muscle and cardiac muscle are involuntary, not voluntary. Choice D is incorrect because 'striated' and 'non-striated' refer to the appearance of muscle fibers, not the main types of muscle tissue in the body.

5. Antigen-antibody binding is the principle behind:

Correct answer: A

Rationale: Rationale: Antigen-antibody binding is the principle behind vaccination. When a vaccine containing antigens (weakened or killed pathogens) is introduced into the body, the immune system produces antibodies that bind to these antigens. This binding triggers an immune response, leading to the production of memory cells that provide immunity against future infections by the same pathogen. Vaccination helps the body develop immunity without causing the disease itself, thereby protecting individuals from infectious diseases. Disinfection and sterilization involve different processes to eliminate or reduce pathogens on surfaces or objects. Antibiotic resistance is a phenomenon where bacteria evolve to resist the effects of antibiotics and is not directly related to antigen-antibody binding.

6. What is the phenomenon responsible for the mirage effect seen in deserts?

Correct answer: B

Rationale: Mirages occur due to the refraction of light by layers of air with different temperatures and densities, bending the light rays and creating the illusion of water on the horizon.
