Many people decided to move from more rural areas that offered land and space for farming to cities that had factories and offered job opportunities
<u>ANSWER:</u>
The statement "the extreme pressure and freezing temperatures of the deep ocean make it dangerous to send humans to the greatest ocean depths" best explains why scientists depend on submersibles to study ocean features .
<u>EXPLANATION:</u>
- The oceans are so vast and deep that humans cannot withstand the pressure in depths.
- Submersibles are developed in such a manner that they can travel to the deepest parts of the ocean and study ocean life.
- Submersibles are vehicles that have the capability to carry humans as well to the deep ocean floors or these can be controlled in an automatic manner.
- The submersibles are provided with tools and technologies that can record ocean floor features and make their study possible.
Answer:
Viruses can replicate inside cells, while bacteria release toxins to destroy cells.
Explanation:
Viruses and bacteria are both considered microorganisms that can be pathogens. Bacteria are singled celled organisms, where as viruses are non-cellular. Therefore, viruses are sometimes considered non-living, or "on the edge of life"
Viruses consist of (at the minimum) a genome surrounded by a protein coat. To replicate, they have to insert their genome into a host cell. This is another reason they are sometimes considered non living.
In contrast, bacteria can release toxins but do not replicate inside cells.
Therefore, the answer is viruses can replicate inside cells, while bacteria release toxins to destroy cells.
