Question
The main source of energy for producers in an ecosystem is A) light energy. B) kinetic energy. C) thermal energy D) chemical energy. E) ATP Which branch of biology is concerned with the naming and classifying of organisms? A) informatics B) schematic biology C) taxonomy D) genomics E) evolution Global warming, as demonstrated by observations such as melting of glaciers, increasing CO_2 levels, and increasing average ambient temperatures, has already had many effects on living organisms. Which of the following might best offer a solution to this problem? A) Continue to measure these and other parameters of the problem. B) Increase the abilities of animals to migrate to more suitable habitats. C) Do nothing: nature will attain its own balance. D) Limit the burning of fossil fuels and regulate our loss of forested areas. E) Recycle as much as possible. Which of these provides evidence of the common ancestry of all life? A) ubiquitous use of catalysts by living systems B) near universality of the genetic code C) structure of the nucleus D) structure of cilia E) structure of chloroplasts Which of the following is (are) true of natural selectionExplanation / Answer
2.A. Light energy
Primary producers in the ecosystem are plants, which harvest light energy from the sun to produce food for consumers.
3. C Taxonomy
Genomics refers to sequencing and analysis of an organism's genome.
4.D. Limit the burning of fossil fuel and regulate our loss of forested areas.
The burning of fossil fuels such as coal and oil contributes to the largest carbon emissions contributing for global warming. Trees are the largest carbon sinks which absorb carbon dioxide from the atmosphere during the process of photosynthesis.
5. B Near universality of genetic code
It strongly implies that all organisms shared a distant common ancestor.
