<h2>Answer:</h2>
The correct answer is option C which is cell can be a plant cell or an animal cell.
Explanation:
- The statement is is that cell has cell membrane. Cell membrane is the outer covering membrane which is present in both cells. While cell wall is a external hard membrane present only in plant cells.
- In the statement D, the presence in the large molecule usually in the center of cell is the indication of plant cell. It gives the upright direction in plants and it stores large amount of water and food.
- Hence the correct answer is option C.
Answer : The correct option is, solution deviate positively from.
Explanation:
According to the Rouault's law, there are two types of deviation which are negative deviation and positive deviation.
In negative deviation, the A-A interactions and B-B interactions are weaker than the A-B interactions that means A-B interactions are more due hydrogen bonding.
For example : chloroform & acetone form a non-ideal solution. The volume of solution will always be more.
In positive deviation, the A-A interactions and B-B interactions are stronger than the A-B interactions.
For example : acetone & benzene form a non-ideal solution. The volume of solution will always be less.
As per question, the interaction between individual liquids are stronger than the solution of two liquid's interactions. That means, the solution deviate positively from.
Hence, the correct option is, solution deviate positively from.
Isotopes are the same elements with the same number of portions but different numbers of neutrons
For instance, the element carbon exists as several isotopes, each having the exact same number of protons (otherwise, it would no longer be carbon if the # of protons changes), and a different number of neutrons
