Answer:
2, 4, and 5 refers to scientific revolution while on the other hand, the remaining statements shows scientific observation.
Explanation:
Cloning has the potential to significantly benefit a great many people, so it should not be considered immoral or risky is refers as scientific observation.
A scientist thinks that he might find serious inconsistencies in the fossil record if he conducts an excavation in a new location is refers scientific explanation because explanation is needed for it which can drawn from the scientific observation.
The rocks present in western Africa and eastern South America formed at the same place and at the same time is scientific observation because the scientists takes the data.
Even if modern organisms are found in ancient portions of the fossil record, this wouldn't challenge the theory of evolution in any way is refers to scientific explanation.
The cloning of organisms is an exciting area of study, and more resources should be be devoted to it so it is refers as scientific explanation.
The age, type, and composition of ancient rocks in western Africa are nearly identical to the age, type, and composition of rocks in eastern South America is scientific observation which is taken by the scientist through research.
Irregularities in the density of the gas causes a net gravitational force that pulls the gas molecules closer together. Some astronomers think that a gravitational or magnetic disturbance causes the nebula to collapse. As the gases collect, they lose potential energy, which results in an increase in temperature.
<span>As the collapse continues, the temperature increases. The collapsing cloud separates into many smaller clouds, each of which may eventually become a star. The core of the cloud collapses faster than the outer parts, and the cloud begins to rotate faster and faster to conserve angular momentum. When the core reaches a temperature of about 2,000 degrees Kelvin, the molecules of hydrogen gas break apart into hydrogen atoms. Eventually the core reaches a temperature of 10,000 degrees Kelvin, and it begins to look like a star when fusion reactions begin. When it has collapsed to about 30 times the size of our sun, it becomes a protostar. </span>
<span>When the pressure and temperature in the core become great enough to sustain nuclear fusion, the outward pressure acts against the gravitational force. At this stage the core is about the size of our sun. The remaining dust envelope surrounding the star heats up and glows brightly in the infrared part of the spectrum. At this point the visible light from the new star cannot penetrate the envelope. Eventually, radiation pressure from the star blows away the envelope and the new star begins its evolution. The properties and lifetime of the new star depend on the amount of gas that remains trapped. A star like our sun has a lifetime of about 10 billion years and is just middle-aged, with another five billion years or so left.

Answer:
Actually, water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
Explanation:
Answer: B Because is that person is sick and sneezes and another does the virus could've made more of its self and wanted another host so the other person with come down with the same sickness.
