Secondary consumers may be carnivores that eat meat or omnivores that eat both plants and animals.
<h3>What are secondary consumers?</h3>
Consumers in biology are organisms (heterotrophs) that uses other organisms for food in order to gain energy.
Consumers can either be primary or secondary. Primary consumers feed directly on plants, hence, are said to be herbivores.
On the other hand, secondary consumers feed majorly on primary consumers, making them carnivorous in nature.
However, secondary consumers may be carnivores that eat meat or omnivores that eat both plants and animals.

Answer:
Cytotoxic T cells
Explanation:
Perforin is the cytosolic protein and upon degranulation forms pores in the target cell. Perforin protein helps in the transport of water and ions.
Perforin is present in the granules of cytotoxic T cells. These cells have the ability to kill virus infected cells and cancer cells. Cytotoxic T cells bind with the class 1 MHC molecules. These cells are also known as CD8+ T cells.
Thus, the correct answer is option (A).
Plants
1: The plant cell was the first cell discovered.
2: Plants cell wall can hold more fluid.
3: The plant cell is static and protected.
Animal
1: The nucleus can be located anywhere in the cell.
2: Animal cells have small vacuoles
3: Animal cells can terminate themselves.
