Explanation
Force can change an object's : Direction (by changing its trajectory) Size (by compressing or expanding it) Speed (by accelerating or decelerating it) But force cannot change an object's mass. Mass is a fundamental property of an object that remains constant , regardless of the forces acting upon it.

Explanation
A force is a Push or a Pull that causes movement.

Explanation
Alcohol is a common choice for laboratory thermometers because it has a relatively high coefficient of expansion. Which allows for accurate temperature measurements.

Explanation
Mercury is a silvery-white liquid metal that was traditionally used in clinical thermometers due to its high coefficient of expansion. It allowing for accurate temperature measurements.

Explanation
Clinical thermometers, also known as medical thermometers . It typically have a narrow range of 35°C to 42°C. Which covers the normal body temperature range of humans (37°C ± 2°C). This allows for accurate measurements of body temperature in medical settings.

Explanation
Laboratory thermometers typically have a range of 10°C to 110°C. It allowing for precise temperature measurements in a variety of laboratory settings.

Explanation
Bacteria are unicellular organisms. They have cell wall but don't have proper nucleus. It doesn't contain chlorophyll . It is used to make medicines, yogurt and cheese. Algae are unicellular with proper cell wall and nucleus. It contain chlorophyll . It causes diseases: Cutleria, Ulva and Volvox.

Explanation
In 1969, Whittaker proposed a system of classification that divided all living organisms into five kingdoms: Monera (bacteria and cyanobacteria) Protista (protozoa, algae, and slime molds) Fungi (mushrooms, molds, and yeasts) Plantae (plants) Animalia (animals)

Explanation
The freezing point of water is 0°C (zero degrees Centigrade).  The boiling point of water is 100°C (one hundred degrees Centigrade).

Explanation
The temperature range of the clinical thermometer is 94°F to 108°F. A clinical thermometer is a device that measures the temperature of the body. A mercury bulb is located at the end of a long, narrow glass tube. The average body temperature is 37° C , but it can range between 35 and 42° C.

Explanation
As a result of the flow of energy (heat) from a region of high temperature to a region of low temperature: the warmer materials cool down and cooler materials warm up. This flow of energy is known as heat transfer. It occurs through conduction , convection, and radiation. As a result, the warmer materials lose energy and cool down, while the cooler materials gain energy and warm up.

Explanation
Heat is a form of energy that flows from a region of high temperature to a region of low temperature. This flow of energy occurs through the transfer of kinetic energy from particles in motion.
