Average mass of the atoms of an element measured in atomic mass unit
It's has an important role in the survival and adaptability of a species. When a species habitat changes, the population needs to be able to adapt to survive: the ability of the population to adapt to the changing environment will determine their ability to cope with an environment challenge.
Hello!
The sentence that best describes what Colton discovers is D) The mass of the melted ice cube remained the same at 4 grams.
<h2>Why?</h2>
The melting of the ice cube is a physical process. That means that it is a process in which the identity of the substance (water) doesn't change, but only how their molecules are arranged.
In melting, a substance in the solid state changes to the liquid state. Its molecules go from having a definite volume and shape to having the same shape as the container that holds it, but there are no changes in the mass of the substance.
If the container is closed, Colton should record the same mass as the initial one, as mass doesn't change in physical processes.
Have a nice day!
Answer:
The correct option is <u><em>D) These advancements are very expensive and not available to everyone.</em></u>
Explanation:
Consider the statement A. It states that the new technological advances uses renewable sources of energy. This is a positive aspect as the energy can be renewed and replaced. The corn from which this energy is derived can be produced over and over again. Hence, this is a positive aspect, not a negative aspect.
Consider statement B. This statement tells us that the new technological advances will not result in warming the Earth's atmosphere by greenhouse effect. Hence, it is a positive aspect.
Consider statement C. It states that the new technological advances will lead to lesser pollution. Hence, it is a positive aspect.
<u><em>Now, consider statement D. It is a drawback because technological advances are too expensive to be used by many people. Hence, it is a negative aspect.</em></u>
