Answer:
C) Water will move out of the cell.
Explanation:
In microbial growth experiments, when a bacterium is placed in a Petri dish with a solution that contains dissolved salt (NaCl) - a hypertonic solution -, the result will lead to the <u>dehydration and shrinking of the bacterial cell</u>.
This condition will eventually cause the rupture of the cell, resulting in the diffuse of H20 molecules from the plasma membrane, that is, the water moving out of the cell.
The answer is; Formation of sea ice increases the salinity of the oceans
When ice form in water, this water is ‘osmotically isolated’ (in solid form) hence making liquid water become lesser in quantity than before. Since the number of dissolved salts remain more or less the same and the liquid water in which it is dissolved has reduced, then the water becomes more concentrated (because they are now more ppm of salts in each cubic amount of the water).
Answer:
Biology is the science that studies life, but what exactly is life? This may sound like a silly question with an obvious response, but it is not always easy to define life. For example, a branch of biology called virology studies viruses, which exhibit some of the characteristics of living entities but lack others. It turns out that although viruses can attack living organisms, cause diseases, and even reproduce, they do not meet the criteria that biologists use to define life. Consequently, virologists are not biologists, strictly speaking. Similarly, some biologists study the early molecular evolution that gave rise to life; since the events that preceded life are not biological events, these scientists are also excluded from biology in the strict sense of the term.
Explanation:
This would be a crowbar. If you have trouble understand this, just visualize what happens when you pry the lid of a box open with a crowbar. You push one end down, and the other end goes up.
