Answer:
Option D = 3.4 g/mL
Explanation:
Given data:
Volume of water = 21.2 mL
Volume of water + object = 27.8 mL
Mass of object = 22.4 g
Density of object = ?
Solution:
First of all we will calculate the volume of object.
Volume of object = Volume of water+ object - volume of water
Volume of object = 27.8 mL - 21.2 mL
Volume of object = 6.6 mL
Density of object:
d = m/v
d = 22.4 g/ 6.6 mL
d = 3.4 g/mL
Dew point.
the temperature to which a parcel of air must be cooled to reach it saturation point.
Answer:
Animal
Explanation:
Animal and plant cells both carry out cellular respiration to generate ATP molecules that store energy for cellular processes. However, only plants have chlorophyll that taps on sunlight for photosynthesis. Plants use photosynthesis to create carbohydrates that are ‘burned’ in cellular respiration for energy.
Answer: Tree use a process called photosynthesis to convert CO2 into sugar and oxygen. The oxygen is a waste product. They release it into the air and that’s the air you breath
