Recent work in classification of life on Earth has shown that what were once called prokaryotes are much more diverse than ever suspected. The prokaryotae are now divided into two domains, the Eubacteria and the Archaeabacteria, as different from each
other as either is from the Eukaryota. One organism, the blue-green algae or cyanobacteria, has left a fossil record that dates back
nearly 3.5 billion years and is among the oldest fossils known. A few hundred years ago, this organism was classified as a plant,
then more recently as a protist. Today it is classified in the kingdom Eubacteria. Which of these would NOT be evidence that
scientists compiled to place cyanobacteria in the Eubacteria.
A)
presence of cell walls containing peptidoglycans
B)
presence of chloroplasts for photosynthesis
C)
contains a nucleoid rather than a nucleus
Eliminate
D)
forms an outer capsule with slime coat

burning of wood and coal

explanation:

the panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in earth's temperatures over the past 50 years.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
