Answer:
Nonspecific resistance; adaptive immunity
Explanation:
The immune response against any antigen can be specific or non- specific. The specific immune response is provided by lymphocytes like B lymphocyte and T lymphocytes because after interaction with antigen they differentiate into memory cells which is saved in memory and when that antigen comes again in the body the memory cell easily ward it off. This type of immunity is called adaptive immunity.
In non-specific immunity, memory is not made after interaction and killing of the antigen or microbes by immune cells because the antigen is killed non specifically. Non-specific resistance is provided by phagocytic cells mainly.
Pre-frontal Cortex (PFC)
The PFC is often one of the last regions of the cerebral cortex to fully develop. It is the area of the brain most associated with executive function, logic, reason, and some anticipation of consequences.
Research estimates that most females' PFC is nearly fully developed by ages 16-21; however, males lag in this development of their PFC by an average of ages 19-24.
Thus, before legal age (18), minors (males > females) are more apt to partake in risk-taking behaviors.
Answer:
There are many plant-like protists, such as algae, that get their energy from sunlight through photosynthesis. Some of the fungus-like protists, such as the slime molds (Figure below), decompose decaying matter. The animal-like protists must "eat" or ingest food. Some animal-like protists use their "tails" to eat.
