1. The process by which one element changes into another through radioactive decay is known as:

• A. Transmutation
• B. Fission
• C. Fusion
• D. Oxidation

Correct answer: A

Rationale: Transmutation - Radioactive decay alters the atomic structure, changing the element's identity (transmutation).

2. Which type of waves are capable of interference and diffraction?

• A. Longitudinal waves only
• B. Transverse waves only
• C. Electromagnetic waves only
• D. Both longitudinal and transverse waves

Correct answer: d

Rationale: Both longitudinal and transverse waves can exhibit interference and diffraction phenomena.

3. What is the process of converting ammonia, a byproduct of protein digestion, into a less toxic form?

• A. Deamination
• B. Transamination
• C. Decarboxylation
• D. Hydrolysis

Correct answer: A

Rationale: Rationale: Deamination is the process of removing an amino group from a molecule, such as converting ammonia (NH3) into a less toxic form like urea. Ammonia is a byproduct of protein digestion and needs to be converted into a less toxic form to be excreted from the body. Deamination is a key step in this process, which occurs mainly in the liver through the urea cycle. Transamination involves the transfer of an amino group from one molecule to another, not the removal of an amino group as in deamination. Decarboxylation is the removal of a carboxyl group from a molecule, and hydrolysis is the breakdown of a compound by adding water.

4. Which type of muscle is characterized by involuntary contractions, is striated, and is primarily found in the heart?

• A. Skeletal muscle
• B. Smooth muscle
• C. Cardiac muscle
• D. Elastic muscle

Correct answer: C

Rationale: The correct answer is C: Cardiac muscle. Cardiac muscle is characterized by involuntary contractions, meaning it contracts without conscious control. It is striated, which refers to the striped appearance of muscle fibers under a microscope. Cardiac muscle is primarily found in the heart, where it plays a crucial role in pumping blood throughout the body. Skeletal muscle (option A) is also striated but is under voluntary control. Smooth muscle (option B) is non-striated and found in organs like the intestines. Elastic muscle (option D) is not a recognized type of muscle tissue.

5. What is the process by which a fertilized egg implants itself in the lining of the uterus?

• A. Fertilization
• B. Implantation
• C. Gestation
• D. Parturition

Correct answer: B

Rationale: The correct answer is B: Implantation. Implantation is the process by which a fertilized egg, or zygote, attaches itself to the uterine wall to establish a pregnancy. Fertilization is the fusion of sperm and egg to form a zygote, which occurs in the fallopian tube. Gestation refers to the period of development of the fetus inside the uterus. Parturition is the process of giving birth. Therefore, implantation specifically refers to the attachment of the fertilized egg to the uterine lining, making it the most appropriate answer in this context.

6. A common indicator used to distinguish between acidic and basic solutions is:

• A. Methyl orange
• B. Phenolphthalein
• C. Universal indicator
• D. All of the above are common indicators.

Correct answer: B

Rationale: Phenolphthalein turns pink in basic solutions and remains colorless in acidic solutions
