Answer:
I'm not sure what the question is???
Human CO2 is a tiny % of CO2 emissions“The oceans contain 37,400 billion tons (GT) of suspended carbon, land biomass has 2000-3000 GT. The atpmosphere contains 720 billion tons of CO2 and humans contribute only 6 GT additional load on this balance. The oceans, land and atpmosphere exchange CO2 continuously so the additional load by humans is incredibly small. A small shift in the balance between oceans and air would cause a CO2 much more severe rise than anything we could produce.”
Progressive age-changes in metabolism and physicochemical properties of cells, leading to impaired self-regulation, regeneration, and to structural changes and functional tissues and organs.
Answer:
C
Explanation:
When researching on the lineage of 2 animals from a common ancestor, one can deduce it accurately from DNA samples and various bodily characteristics from the body of the 2 animals in comparison to the common ancestor.
A) Strands of DNA allows for scientist to deduce the percentage similarity between 2 animals. The more similar means that the closer the relatedness is between 2 species.
B) Bones and muscle structure gives one a rough gauge on similarity of both organisms. E.g. Compare human bone, muscle to chimpanzee bone muscle.
C) Comparison of food items is the worst methods as different species may feed on different types of food due to natural selection. E.g. Finch bird example on the galapegos island or sth.
D) growth of embryos of similar animals would have similar developmental stages and changes that is quite distinct to each species, allowing one to deduce the closeness of the 2 animals to a common ancestor.
Answer:
Ribose
Explanation:
Ribose, also called D-ribose, five-carbon sugar found in RNA (ribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the RNA polymer and binds to nitrogenous bases.
