Answer:
3.45g/cm³
Explanation:
The density of a substance/object can be calculated by using the formula:
Density = mass/volume
Where;
Density = g/cm³
Mass = grams
Volume = cm³
According to this question, a student measured the mass and volume of an object using a triple beam balance and a graduated cylinder. The sample has a mass of 22.4 grams and a volume of 6.5cm³.
Hence, the density of the object can be calculated this;
Density = mass/volume
Density = 22.4/6.5
Density = 3.4461
To the nearest hundredth, the density of the object = 3.45g/cm³
Basically because they either have beating hearts, organs, skeletons, and more that plants and other things do not
Answer:
One biotic factor includes soil, air(oxygen and carbon dioxide), water.
One biotic factor includes animals and plants.
