Answer: C). biomagnification
Biomagnification is the phenomena in which toxic chemicals released from industrial and agricultural wastes flow into water bodies and contaminate them. These toxic chemicals causes diseases, genetic mutations, birth defects and death in organisms which indirectly or directly take them. These toxic chemicals enters into the food chain and affects mainly the organisms which are at higher trophic levels. They get settle at the bottom of the water body with sediments and organisms feed on these sediments. These toxic chemicals are not digested therefore they are transferred from one trophic level to higher trophic level in an undigested and unchanged form. In the highest trophic level the concentration of these toxic chemicals becomes highest and result in mortality of organisms. This shows magnifying and enlarged destruction of organisms in a food chain hence named biomagnification. It affects endangered species of predators like fishes, aquatic mammals and birds which eat fishes.
Storage of energy its the correct answer
Answer:
Explanation:
Organic compounds contain chemically bonded carbon atoms, sometimes even hydrogen atoms to form hydrocarbons, and inorganic compounds do not contain these atoms.
Answer:
They probably use aerobic respiration.
Explanation:
A travel distance of 11.500 kilometers in 9 days covered by flying surely requires a lot of energy.
- If cells are fermenting, the ATP (energy) they generate only comes from glycolysis, which produces 2 ATP molecules.
- If they are using aerobic respiration, glucose is completely oxidized to CO₂ through glycolysis and the Citric Acid Cycle, and the electrons enter the electron transport chain to finally reduce oxygen into water. In the complete process, up to 36 ATP molecules are produced.
In sum, aerobic respiration is much more efficient to generate energy than fermentation, so it's probably the main metabolism of the flight muscles in bar-tailed godwits.
Variation: people in the population need to have different traits.
Heritability: the different traits need to be able to pass from parent to offspring.
Differential Mortality: people need to have the probability of survival that is a function of the trait in question.
