Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.
Answer:
The correct answer is 6.67 %.
Explanation:
The average osmotic pressure of the brain is 300 mM
Given the concentration of solution is 280 mM
Difference is 300 - 280 = 20 mM
This difference is sufficient to stimulate osmosis and make water move from CSF to the brain until the concentration becomes similar.
Also, it is known that the volume of brain is about 1200 ml on an average,
Volume of fluid moved because of osmosis = 20 mM / 300 mM * 1200 ml = 80 ml
Percent swelling of brain = 80 ml / 1200 ml * 100 = 6.67 %
the process that plants go through to capture and use energy from the sun to make food (glucose ) is called Photosynthesis

A hypothesis is a supposition made by the scientist. In order for a hypothesis to be a scientific hypothesis, the scientific method requires for it to be tested. If a hypothesis cannot be tested, it cannot be scientific hypothesis. It is important to state the hypothesis clearly at the beginning of a scientific paper. This enables the reader to understand the problem. </span>
The correct answer is silent mutation .
There are sequences present in the body where a point mutation occurs but the protein formed is still the same
