Question

which organelles are only found in animal cells? *
□ lysosome
□ cell membrane
□ nucleus
□ centrosomes/centrioles
□ golgi bodies

a beaker of water is heated on a hot plate. after the water reaches its boiling point, it remains at a constant temperature, even though the hot plate continues to add heat. this phenomenon is a direct result of which property of water?
○ high heat of vaporization
○ universal solvent
○ adhesion
○ cohesion

the high specific heat capacity of water allows it to absorb a large amount of heat energy without a significant change in its temperature. this property is vital for living organisms because it allows for
○ regulation of body temperature
○ transport of nutrients and gases
○ ability to dissolve a wide range of substances
○ the formation of a rigid structure in plant cells

Explanation:

1. Lysosomes are found in animal cells and some protists. Cell - membranes are present in all cells (animal, plant, etc.). Nucleus is present in eukaryotic cells including plants and animals. Centrosomes/centrioles are only found in animal cells and some lower plants. Golgi bodies are present in both plant and animal cells.
2. When water reaches its boiling point and remains at a constant temperature while heat is still being added, it is due to the high heat of vaporization. This property requires a large amount of heat energy to convert water from liquid to gas phase without a temperature increase during the phase - change.
3. The high specific heat capacity of water allows living organisms to regulate body temperature. It can absorb or release a large amount of heat without a significant change in its own temperature, thus helping to maintain a stable internal environment.

Answer:

1. Centrosomes/Centrioles
2. High Heat of Vaporization
3. regulation of body temperature
