Answer:
c) Both are functions of blood, that is, to carry oxygen to the cells and also remove wastes from the body.
Explanation:
Blood is a form of connective tissue and is made up of red blood cells, white blood cells, platelets and blood plasma. The red blood cells contains a metallo-protein structure known as hemoglobin. This hemoglobin binds to the oxygen and carry them to the cells and the tissues for proper functioning of them. The waste products like carbon dioxide is carried by the blood from the body tissues to expel it out from the body.
In order to reduce the activation energy in a chemical reaction. a catalyst is introduced to lower the activation energy of a reaction, so that a chemical reaction can take place. However, by increasing the temperature of a reaction helps the effect in increasing the number of reactant particles that have more energy than the activation energy. Therefore, by reducing the activation energy, the reaction would go faster.
The correct answer is B). The potato cells lost water to the surroundings.
The salt water solution is hypertonic as compared to cell of a potato slice. In other words cells of potato slice is hypotonic to salt solution. Water always moves from hypotonic to hypertonic solution if they separated by semipermeable membrane. Thus, when potato slice is dipped into salt water, ex-osmosis that is water will move out of the potato slice into the salt solution. As a result into shrinking of potato slice.
I guess it just works that way
Question 1 is D
Question 2 is B (because the aunt was crying and they say Eddie would write to her first making it seem the aunt was eddies mom)
Question 3 is C I believe
