Which process is represented by the diagram below?

A. emulsification

B. excretion

C. absorption

D. peristalsis

  • Q #2: Salmonella bacteria can cause humans to have stomach cramps, vomiting, diarrhea, and fever. The effect these bacteria have on humans indicates that Salmonella bacteria are

    A. predators

    B. pathogenic organisms

    C. parasitic fungi

    D. decomposers

    Answer Explanation

    B) pathogenic organisms

    - Correct: Salmonella bacteria are pathogenic organisms, meaning they can cause disease in humans and other animals. When ingested, Salmonella bacteria can lead to symptoms such as stomach cramps, vomiting, diarrhea, and fever. Salmonella infection, known as salmonellosis, is a common cause of foodborne illness, often associated with the consumption of contaminated food, particularly undercooked poultry, eggs, and unpasteurized dairy products.

    A) predators

    - Incorrect: Predators are organisms that hunt, kill, and consume other organisms for food. Salmonella bacteria are not predators; they do not actively hunt and consume other organisms.

    C) parasitic fungi

    - Incorrect: Salmonella bacteria are not parasitic fungi. Parasitic fungi are fungi that derive nutrients from living organisms, often causing harm or disease. Salmonella bacteria are a distinct type of pathogenic bacteria, not fungi.

    D) decomposers

    - Incorrect: Decomposers are organisms that break down and feed on dead organic matter, aiding in the process of decomposition. Salmonella bacteria are not decomposers; they are pathogenic bacteria that can cause illness in humans and animals.

  • Q #3: Which components of the human diet contain the greatest amounts of sugars and starches?

    A. meat and eggs

    B. fruits and vegetables

    C. minerals and milk

    D. water and vitamins

    Answer Explanation

    B) fruits and vegetables

    - Correct: Fruits and vegetables contain the greatest amounts of sugars and starches in the human diet. Both fruits and vegetables are rich sources of carbohydrates, including natural sugars, fiber, and starches. These carbohydrates provide a readily available source of energy for the body. Examples of fruits with natural sugars include apples, bananas, and grapes, while starch-containing vegetables include potatoes, corn, and peas.

    A) meat and eggs

    - Incorrect: Meat and eggs are primarily sources of proteins and fats, not sugars and starches. They contain minimal amounts of carbohydrates.

    C) minerals and milk

    - Incorrect: Minerals are inorganic compounds essential for various physiological functions, and milk is a source of proteins, fats, and carbohydrates (mainly lactose, a sugar). While milk contains some sugars, fruits and vegetables typically contribute more significant amounts of sugars and starches to the diet.

    D) water and vitamins

    - Incorrect: Water and vitamins are essential components of the diet, but they do not contain sugars and starches. Water is a vital component for hydration, and vitamins are organic compounds required for various biochemical processes in the body.
