Density can be calculated using the following rule:
Density = mass / volume
Therefore:
mass = density * volume
We are given that:
Density = 75 g/ml
volume = 12 ml
Substitute with these givens in the equation to get the mass as follows:
mass = density * volume
mass = 75 * 12
mass = 900 g
Answer:
Animal cell lacks chloroplasts and a cell wall
Explanation:
Unlike animal cells, plant cells have chloroplasts and a cell wall. In a plant cell, the chloroplasts work to use photosynthesis in order to turn light into energy for the plant cell. Animal cells do not utilize light energy, and therefore do not carry out photosynthesis and do not have chloroplasts.
Additionally, the plant cell has a protective cell wall and a cell membrane, while animal cells only have a cell membrane. This is because the plant cells' cell wall provides additional strength and protection against outside factors, such as osmosis.
