A testable question is something you need data for, ex: if i bounce a bouncy ball from larger heights, how high will it fly? it can't be just a regular yes or no question
Answer:
having exactly the same DNA sequences, twins start accumulating genetic variation from the earliest stages of development, researchers at Iceland-based company deCODE genetics found, meaning that one twin harbors variants that aren't present in the other.
During succession, the limiting factor that may affect the sun-loving mosses when taller plants start to grow around them is that there will be a competition in the water available in the soil since there is a high chance that these taller plants could use the water up more. In addition, these mosses will not get the full benefit from the sun because the taller plants are blocking.
Answer:
3. is activated immediately upon infection.
Explanation:
Innate immunity is the nonspecific immunity. These immune defenses are present at birth and do not involve specific recognition of a microbe. Being nonspecific in nature, it acts against all microbes. Innate immunity includes the first and second lines of defense.
Some of the examples of components of innate immunity among the first line of defenses are physical and chemical barriers of the skin and mucous membranes. Innate immune responses are the immunity’s early warning system that is generated immediately after the encounter with a pathogen to prevent them from entering the body and to help eliminate the ones that have entered the body.
Once a microbe has entered the body, secretion of antimicrobial substances and activities of natural killer cells, phagocytes, the process of inflammation, etc. serve to eliminate it from the body. All these responses are the components of innate immunity.
