Explanation

Animals can be classified into three main categories based on their food type:

1. Herbivores (plant-eaters): These animals eat only plants, including leaves, stems, roots, flowers, fruits, and seeds. Examples: Cows, Deer, Rabbits, Elephants
2. Carnivores (meat-eaters): These animals eat only meat, primarily from other animals. Examples: Lions, Tigers, Bears, Wolves
3. Omnivores (both plant and meat-eaters): These animals eat both plants and animals. Examples: Humans, Pigs, Bears (some species), Chimpanzees

Explanation

• Introducing mosquito-eating fish, such as guppies or mosquitofish (Gambusia affinis), into water bodies can help control mosquito populations, including the dengue mosquito (Aedes aegypti).
• These fish feed on mosquito larvae and help prevent them from developing into adult mosquitoes.

Explanation

Kwashiorkor is a severe form of protein-energy malnutrition, and its symptoms include:

• Fatigue: Weakness and lack of energy
• Diarrhea: Frequent and watery stools
• Irritability: Mood swings and crankiness
• Impairment of mental health: Depression, anxiety, and cognitive impairment
• Stunted growth: Slowed growth and development, leading to short stature

Additionally, other symptoms of Kwashiorkor may include:

Explanation

Asthma and lung cancer are two main disorders that affect the lungs.

• Asthma: a chronic inflammatory disease that causes recurring episodes of wheezing, coughing, chest tightness, and shortness of breath due to the inflammation of the airways.
• Lung Cancer: a disease caused by the abnormal growth of cells.

Explanation

• During breathing, the clean, moist, and warm air enters the windpipe called the Trachea.
• The trachea is also known as the windpipe.
• It is a tube that connects the throat (pharynx) to the lungs, allowing air to pass through during breathing.

Explanation

Malignant tumors of the larynx can spread through multiple pathways, including:

1. Lymphatic channel: The most common route of metastasis for laryngeal cancer is the lymphatic system.
2. Nerve: Perineural invasion can occur, although it is less common than lymphatic spread.
3. Blood: Hematogenous spread (through the bloodstream) can occur, leading to distant metastases.
4. Direct spread to distant structures: Laryngeal cancer can directly invade adjacent structures such as the thyroid, esophagus, and neck muscles
   

Explanation

For high‐risk GTN, EMA/CO is the most commonly used first‐line therapy, with platinum‐etoposide combinations

EMA/CO therapy consists of the combination of etoposide, methotrexate, and actinomycin D, along with cyclophosphamide and vincristine.

Explanation

The statement that is not correct regarding snake bites is The type of first aid given to the victim will decide the severity of the outcome.

The first aid given may help in stabilizing the victim temporarily but does not ultimately determine the severity of the outcome.

While prompt and appropriate first aid can help mitigate the effects of a snake bite,

the severity of the outcome is influenced by various factors including:

• the type of snake
• the amount of venom injected
• the location of the bite
• the size and health of the victim
• the availability and timeliness of medical treatment.
