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.

Answer:
- Random dispersion occurs with dandelion and other plants that have wind-dispersed seeds that germinate wherever they happen to fall in a favorable environment.
- Clumped dispersion is seen in plants that drop their seeds straight to the ground, such as oak trees, or animals that live in groups, such as schools of fish or herds of elephants.
- Clumped dispersions may also result from habitat heterogeneity. If favorable conditions are localized, organisms will tend to clump around those, such as lions around a watering hole.

C) centrioles is correct
All other parts have important functions but only centrioles help with chromosomes
