Answer:
D. 200%
Explanation:
While Americans constitute the 5% of the world population, they use around the 24% of the world's energy.
Then, if the 100% of the population were like the Americans, we have:
5%*x = 100%
x = 100%/5% = 20
the whole population is 20 times the population of the US, then the total energy used is 20 times the energy used in the US.
Then the energy that the 100% of the population would use is equal to:
20*24% = 480%
So we actually would need like 5 Earths.
The option is 200%

A technique that can be used to separate proteins based primarily on the presence of non-polar residues on their surface is called A) ion-exchange chromatography. B) gel filtration chromatography. C) affinity chromatography. D) gel electrophoresis. E) hydrophobic interaction chromatography.
Answer:
E) hydrophobic interaction chromatography.
Explanation:
Hydrophobic interaction chromatography (HIC) is a methodology used to separate protein molecules depending on their hydrophobicity. HIC enables the separation and purification of proteins by using a reversible interaction between the target protein and the hydrophobic ligand of a HIC resin such as, for example, methacrylate-based beads. This interaction is influenced by the running buffer (high salt concentrations favor hydrophobic interactions). HIC enables the separation of proteins under low denaturation conditions, thereby preserving their biological functions.

Sea turtles nest only at their own birthplaces. After hatching on the beach, the turtles enter the water to begin their far-ranging migration, only returning to their birthplace to nest some 15 to 30 years later. It has been hypothesized that newborn sea turtles learn the smell of their environment, and it is this smell that stimulates the turtles to return to nest.
Which one of the following would be most important to know in evaluating the hypothesis in the passages?
(A) how long the expected life span of sea turtles
(B) what the maximum migration range of the sea turtles is
(C) whether many beaches on which sea turtles were hatched have since been destroyed by development
(D) before returning to the nest, sea turtles are outside the area where the smell of their birthplace would be perceptible
(E) whether both sex of sea turtles are actively involved in the nesting process

an experiment is replicable if different scientist can do the experiment and get the same results true or false
Answer:
True
Explanation:
if multiple scientist do the same thing that means they are replicating the experiment
The statement "An experiment is replicable if a different scientist can do the experiment and get the same results" is definitely true.
What is a scientific experiment?A scientific experiment may be defined as a complete set of procedures that are carried out under controlled conditions in order to determine the validity and accuracy of a hypothesis or construct a discovery.
If multiple scientists construct the same hypothesis and perform identical research and received the same results. It implies that they are just replicating the same experiment number of times.
But the only difference is that they understand different things and methodology very closely based on such outcomes. This gives each scientist a sense of special perception based on facts and evidence.
Therefore, the statement "An experiment is replicable if a different scientist can do the experiment and get the same results" is definitely true.

A boy picks up an earthworm and place it on a white tile. He observed that the earthworm has difficulty in moving forward.
Explain why.
Answer:
A number of tiny hair like bristlez are present on the lower surface pf an earthworm's body. These bristles help it to get a good grip on the surface of q ground.However these bristles donot provide good grip on plain glass tiles.
Earthworms have microscopic hairs or bristles all over their body which provide the necessary traction while movement. These bristles or setae are present on each segment of their body and it imparts the necessary grip or anchorage for forward and backward movement.
Tile is smooth in nature so earthworms cannot move as the setae will not get sufficient surface support to move the body.
