The mirror neurons were first discovered on monkeys, and they were tested with fMRI (functional Magnetic Resonance Imaging) - so the correct answer is "MRI “monkey see monkey do” tests on monkeys performing tasks". This means that an MRI scan was performed as the monkeys watched people perform tasks.
Active and passive humoral immunity are both mechanisms of adaptive immunity that use antibodies. yes this is true
- Our adaptive immune system protects us from infection-related mortality. An new-born born with a significantly compromised adaptive immune system may die shortly unless extreme steps are taken to isolate it from a wide range of infectious agents such as bacteria, viruses, fungi, and parasites.
- The purpose of adaptive immunity is to eliminate invading infections as well as any harmful chemicals they create. Because these reactions are damaging, it is critical that they only occur in response to molecules that are alien to the host and not to molecules that are native to the host. The adaptive immune system's capacity to identify what is foreign from what is self is a fundamental feature.

The best answer is C.
Plant cells are surrounded by a cell wall and have chloroplasts whereas animal cell do not.
The cell wall is a covering that is rigid whose main purpose is to protect the cell and give structural support as well shape to the plant cell. The equivalent of a cell wall in animal cell is the cell membrane, which has distinct differences from the plant cell wall.
Chloroplasts are plant cell organelles which carry out photosynthesis by which plants make their own food. These are absent from animal cells because animals do not make their own food, they ingest it from external sources.
