8. explain how the following experiment provided support for the claim that dna is the primary source of heritable information.

two experiments are run side by side:

1. one set of virus particles is labeled with the sulfur-35 isotope. a second set is labeled with phosphorus-32 isotope.

2. each set of labeled virus particles is incubated with different batches of the same bacteria.

3. following infection of the bacteria by the virus particles, the bacteria are separated from the virus particles by agitation in a blender.

4. the bacterial cells are separated from the virus particles by centrifugation.

5. the supernatant and pellet (two separated components) from each batch are analyzed to determine the locations of the isotope labels.

results:

1. radioactive sulfur is found in the supernatant.

2. radioactive phosphorus is found in the cell pellet.

3. a new generation of viable virus particles emerge from the bacteria cells when they are reconstituted in liquid culture.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

it’s lava came from an explosive eruption

did you fail the test? xd
