1. Which sexually transmitted infection (STI) can potentially cause infertility in both men and women if left untreated?

A. Human papillomavirus (HPV)
B. Chlamydia
C. Gonorrhea
D. Syphilis

Correct answer: D

Rationale: The correct answer is D: Syphilis. Syphilis is a sexually transmitted infection that can potentially cause infertility in both men and women if left untreated. In men, untreated syphilis can lead to damage to the testicles and epididymis, affecting sperm production. In women, syphilis can result in pelvic inflammatory disease (PID) which can lead to scarring and blockages in the fallopian tubes, causing infertility. While other STIs like chlamydia and gonorrhea can also lead to infertility if left untreated, syphilis is particularly known for its severe impact on reproductive health in both genders.

2. What is the end result of mitosis in animal cells?

A. The production of two identical daughter cells
B. The production of four haploid cells
C. The production of a single diploid cell
D. The production of a single haploid cell

Correct answer: A

Rationale: Rationale: Mitosis is a type of cell division that results in the production of two identical daughter cells, each having the same number of chromosomes as the parent cell. This process is essential for growth, repair, and maintenance of multicellular organisms. During mitosis, the replicated chromosomes are separated into two nuclei, and the cell then divides to form two genetically identical daughter cells. Options B, C, and D are incorrect because mitosis does not result in the production of four haploid cells, a single diploid cell, or a single haploid cell.

3. The part of the brain responsible for balance and coordination is the:

A. Cerebellum
B. Cerebrum
C. Hypothalamus
D. Thalamus

Correct answer: A

Rationale: The correct answer is A: Cerebellum. The cerebellum is the part of the brain responsible for balance and coordination. It receives information from the sensory systems, spinal cord, and other parts of the brain to coordinate voluntary movements such as posture, balance, and speech. The cerebrum (option B) is responsible for higher brain functions such as thinking and decision-making. The hypothalamus (option C) is involved in regulating basic biological needs such as hunger and thirst. The thalamus (option D) acts as a relay station for sensory information. Therefore, the cerebellum is the specific part of the brain that plays a crucial role in maintaining balance and coordination.

4. Describe the mechanism by which genes are transmitted from parents to offspring.

A. Blending of parental genes, resulting in an average of their traits.
B. Random assortment of alleles during meiosis, leading to unique combinations in each offspring.
C. Inheritance of solely dominant alleles, masking the influence of recessive ones.
D. Direct transfer of both parental genomes, creating identical copies of the parents.

Correct answer: B

Rationale: Rationale: A) Blending of parental genes, resulting in an average of their traits, is not an accurate description of how genes are transmitted. In reality, genes are not blended but rather passed down in discrete units. B) Random assortment of alleles during meiosis is the correct mechanism by which genes are transmitted from parents to offspring. During meiosis, homologous chromosomes separate, and alleles are randomly distributed to the gametes, leading to unique combinations of genes in each offspring. C) Inheritance of solely dominant alleles, masking the influence of recessive ones, is not an accurate representation of gene transmission. Offspring inherit alleles from both parents, and the expression of dominant or recessive traits depends on the specific combination of alleles. D) Direct transfer of both parental genomes, creating identical copies of the parents, is not how genes are transmitted. Offspring inherit a unique combination

5. What is the primary function of DNA polymerase?

A. Packaging DNA
B. Replicating DNA
C. Transcribing DNA
D. Translating mRNA

Correct answer: B

Rationale: Rationale: DNA polymerase is an enzyme responsible for synthesizing new DNA strands during DNA replication. It adds nucleotides to the growing DNA strand based on the template provided by the existing DNA strand. This process ensures that genetic information is accurately copied and passed on to daughter cells during cell division. Packaging DNA (option A) refers to the coiling and organization of DNA into chromatin, a process involving histones and other proteins. Transcribing DNA (option C) involves the synthesis of RNA from a DNA template, a process carried out by RNA polymerase. Translating mRNA (option D) refers to the process of protein synthesis where the information encoded in mRNA is used to assemble amino acids into a polypeptide chain.

6. Stephanie is a new Staff Educator of a private tertiary hospital. She conducts orientation

A. Organizational structure
B. Policy
C. Job description
D. Manual of procedures

Correct answer: D

Rationale: The correct answer is D, 'Manual of procedures.' During orientation, Stephanie as a Staff Educator would likely refer to the manual of procedures to provide new employees with detailed instructions on how to perform their job duties. This manual outlines the specific procedures, protocols, and guidelines that employees are expected to follow within the organization. It serves as a valuable resource for new hires to understand the standard operating procedures and expectations within the hospital setting, making it a crucial document to reference during orientation.
