Answer: Earthquakes, volcanic activity, mountain-building, and oceanic trench formation
Answer:
All living things are made of cells
Cells form from previously existing cells
Explanation:
According to the Cell Theory, all forms of life are composed of one or more cells, whereby cells are the fundamental building blocks in all living organisms. All cells are composed of inorganic molecules (e.g., water) and carbon-based organic molecules (e.g., carbohydrates, lipids, nucleic acids, etc). All the new cells arise from the division of pre-existing cells. Louis Pasteur showed cells would only grow in broth if they are exposed to air (oxygen), thus refuting the idea of spontaneous generation. In multicellular eukaryotic organisms, these cells can be organized in tissues, organs and organ systems.
Answer: B) Light to Mechanical Energy
Explanation:
Answer:
With a warm front, boundary between warm and cold air is more gradual than that of a cold front, which allows warm air to slowly rise and clouds to spread out into gloomy, overcast stratus clouds. Precipitation ahead of a warm front typically forms into a large shield of steady rain or snow.
Answer:
E
Explanation:
A mutation that confers phenotypic benefits to individuals or a group of individuals would be considered a beneficial mutation.
<em>Mutation involves a sudden change to the gene coding sequence of the DNA. It can occur as a result of substitution, duplication, deletion, inversion, insertion, etc of purine or pyrimidine bases of the DNA.</em>
<u>These changes can be harmful, beneficial, or neutral to individuals. Those that have neutral effects in individuals are also called silent mutations.</u>
In the case of a duplication causing trichomatic vision in humans, it represents a form of beneficial mutation because it enables humans to be able to distinguish between red, green, and blue colors. The ability to distinguish among these colors improves the quality of life of humans.
