Answer:
This is a question of the ration surface-volume. It is more efficient a shape that has more surface than volume
Explanation:
Imagine the shape of a mouse and an elephant in a cold environment. Who will lose heat faster? The answer is the mouse, for its volume (which is small compared to the elephant), the surface for which it can lose heat is very large. In contrast, the surface for which the elephant can lose heat is very small for its volume.
The same happens with nutrients if you have a great volume and a small surface is more difficult to exchange them.
Answer:
The correct answer is option - D. phosphorylation.
Explanation:
The CARD11 or caspase recruitment domain-containing protein 11 is a gene that provides instructions for gene expressing to make a protein in the function of lymphocytes in the immune system. Lymphocytes like B and T cells are activated with the help of cascade reactions in which these genes provide information.
The protein that activates is PKC which is a kinase enzyme that implicates that the process that activates CARD11 is phosphorylation.
Thus, the correct answer is option - d - phosphorylation.
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.
