The second line of defense is nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals: Phagocytic cells ingest and destroy all microbes that pass into body tissues. For example macrophages are cells derived from monocytes.
Answer:
Lack of food sources, the lack of habitat, competition and evolving ways to compete.
Explanation:
Lack of food sources, the lack of habitat, competition and evolving ways to compete are the ecological conditions that is responsible for the rapid diversity of some lineages. With the passage of time, changes occurs in the lineages due to climate change which causes some species to extinct and some to evolve which attains adaptability to the environment. Due to climate change food is unavailable to the organisms which is the main cause of its extinction.
The recommended dietary allows differs with age, sex, and health status. Leen is an healthy female adult so the RDA should be 15 mg so if she has consumed 6 mg the percentage is 6/15*100 = 40%
With the presence of a heterozygous allele for earlobes, the gametes produced by the father will have 50 percent chances of bearing an allele for attached earlobes. This means that half of the gametes will have an allele for attached earlobes, and half of them will have an allele for detached earlobes.
<span>Both chloroplasts and cyanobacteria perform photosynthesis. They also share many characteristics, including an inner and outer membrane, a nucleoid, thylakoids, lipid droplets and ribosomes. These similarities lead to the suggestion chloroplasts evolved from cyanobacteria.</span>
