Answer:
The correct answer is option B, that is, the cells of the animal body are defective in endocytosis.
Explanation:
In the given case, in my opinion, one should perform the experiment in a similar manner with no change. An experiment is done many times in order to omit any influences of sampling or handling on the outcomes of the study. For this purpose, the repetitive experiments have to be performed in a similar way as the previous ones were performed. After that, the outcomes of the repetitive experiment and the initial one are compared.
If any conditions or variables are changed in the experiment, the outcomes of the repeated experiment cannot be compared with the initial one. As variations in experimental material, variables, or procedure would have influenced the outcomes.

Buffers such as bicarbonate buffer, citrate buffer and phosphate buffer are important in living system. pH of blood is near to neutrality (7.4). If the pH of blood increases, these buffers help in maintaining the blood pH. Increase in blood pH leads to certain diseases such as alkalosis. This further leads to muscle spasm and respiratory diseases.
Bicarbonate buffer helps to maintain the blood pH if it falls towards acidic range or increases towards alkalinity. It helps in decreasing acidity and increasing alkalinity by forming carbon dioxide gas. Increase in blood pH towards alkalinity is also maintained by excreting the bicarbonates into the urine. Similar action is also seen in case of phosphate buffer and citrate buffer.
Answer: If these buffers are not present in a living system then the change of pH cannot be altered or put back to normal. These buffers help to maintain the pH of the living system so that cells can work properly.
Water's polarity can be responsible for many of it's properties including it's attractiveness to other molecules. Water molecules attract one another based on the attraction between the positive end of one water molecule and the negative end of the other. Also the unequal sharing of electrons gives the molecules a slight negative charge near it's oxygen atom and a slight positive charge in it's hydrogen molecule.
