FPSC Everyday Science MCQs

The heart contracts rhythmically to circulate blood.
It supplies tissues with oxygen and nutrients.

Microorganisms use sugars during fermentation.
The process is used in bread, yogurt, and other foods.

Organs combine multiple tissue types for specific functions.
The heart and lungs are examples.

Yeast ferments sugars and releases carbon dioxide.
Gas bubbles expand within the dough.

Organ systems coordinate complex tasks.
Examples include the digestive and circulatory systems.

Lactic-acid bacteria ferment milk sugar.
The acid causes proteins to thicken and gives yogurt its sour taste.

Xylem conducts water and dissolved minerals from roots.
It also helps support the plant.

Pasteurization heats food or drink for a specified time.
It improves safety while limiting quality changes.

Many foodborne bacteria grow quickly at warm temperatures.
Prompt refrigeration reduces the risk.

Cells are the smallest units capable of carrying out life processes.
All living organisms consist of one or more cells.

The nucleus contains most of the cell's genetic material.
It directs protein production and cell activities.

Mitochondria produce much of the cell's ATP through respiration.
ATP supplies usable energy for cellular work.
