- Deferens:
It transport sperm from the epididymis (where sperm matures and is stored) to the urethra during ejaculation.
- Testicle:
Production of sperm through a process called spermatogenesis.
- Seminal Vesicles:
It secretes a fluid that makes up a significant portion of the semen.
(1aiii)
- Identical Twins:
Identical twins, also known as monozygotic twins, originate from a single fertilized egg (zygote) that splits into two embryos. This usually occurs early in the development of the embryo. As a result, identical twins share nearly identical genetic material because they come from the same fertilized egg.
- Fraternal Twins:
Fraternal twins, also known as dizygotic twins, result from the simultaneous fertilization of two separate eggs by two different sperm. In this case, two eggs are released during the same menstrual cycle, and each egg is fertilized by a different sperm. Fraternal twins, therefore, share about 50% of their genetic material, just like regular siblings born at different times.

(i) The liver is responsible for detoxifying harmful substances, such as drugs and toxins, by breaking them down into less harmful compounds that can be excreted from the body
(ii) It regulates blood glucose levels by storing excess glucose as glycogen and releasing it when needed.
(iii) It is involved in the synthesis of important proteins, including blood-clotting factors and albumin.
(iv) It is involved in the synthesis of important proteins, including blood-clotting factors and albumin.
(iv) Liver aids in the digestion and absorption of fats in the small intestine.

Vital statistics; refer to a collection of data related to important life events, such as births, deaths, marriages, and divorces. These statistics provide valuable information about a population's demographics, health trends, and overall well-being.
(2cii)
Antibiotics; are medications that are used to treat bacterial infections. They work by either killing bacteria or preventing their growth. Antibiotics are prescribed by healthcare professionals and can be taken orally, applied topically, or administered through injections, depending on the type and severity of the infection.
(2ciii)
Heredity; refers to the passing down of traits and characteristics from parents to their offspring. It involves the transmission of genetic information from one generation to the next. Through heredity, individuals inherit traits such as eye color, hair texture, height, and susceptibility to certain diseases. This genetic information is carried by genes, which are segments of DNA located on chromosomes.
(3ai)
Causative Organism: poliovirus
(3aii) Sources of Infection:
(i) Fecal-Oral Transmission
(ii) Person-to-Person Transmission
(iii) Contaminated Surfaces
(3aiii)
(i) Sore throat
(ii) Fever
(iii) Paralysis
(iv) Gastrointestinal issues
(3aiv)
(i) Vaccine
(ii) Improving hygiene
(iv) Surveillance and Outbreak Response

(i) Influenza (Flu): An infectious respiratory disease caused by influenza viruses.
(ii) HIV/AIDS: Human Immunodeficiency Virus (HIV) causes Acquired Immunodeficiency Syndrome (AIDS).
(iii) Dengue Fever: A mosquito-borne viral infection causing flu-like symptoms.
(iv) Measles: Caused by the measles virus, leading to respiratory and systemic symptoms.
(3c)
(i) Metabolic diseases result from abnormalities in the body's chemical processes and metabolism While Genetic diseases are caused by abnormalities or mutations in an individual's DNA.
(ii) Metabolic disorders may or may not have a genetic component. Some metabolic diseases are acquired or result from environmental factors, while others may have a genetic basis. On the other hand, Genetic diseases are inherently linked to the individual's genetic makeup and are often hereditary, passed down from one generation to the next through genes.

(4biii)
Immunization is provided at various levels of healthcare, including primary healthcare settings such as clinics, hospitals, and community health centers. It's usually offered by healthcare professionals like doctors, nurses, and pharmacists.
