<u>ANSWER:</u>
Diffusion is used by bacteria to transfer antibiotic resistance genes to other cells.
<u>EXPLANATION:</u>
- When bacteria becomes resistant to antibodies, it loses the ability to be inhibited.
- Diffusion in such case is used by bacteria to transfer the antibiotic genes to another species. This is because bacteria has the ability to replicate and transfer resistance by engulfing DNA from neighboring cells.
- Bacteria has the ability to take naked DNA encoding from similar species for the purpose of resistance and diffusion is the process that makes it possible.
Answer:
Option). the ability to remember the antigen it encounters
Explanation:
The adaptive or acquired immunity is a type of immunity, which develops by the exposure of pathogens during lifetime. Four features of adaptive immunity includes specificity, diversity, memory, and ability to differentiate between self and non-self.
Cells of adaptive immunity (B cells and T cells) are specific for pathogens. Once the antigens or their components are recognized by pathogens, these cells produce effector cells and memory cells.
These are the memory cells that remember the antigens and provide a rapid and more efficient response during subsequent encounters of those antigens.
Thus, the correct answer is first option.
Adult stem cells are capable of only limited differentiation
