Answer:
Newton's three laws of motion are examples of laws in physical science. A scientific law states what always happens but not why it happens. Scientific theories answer “why” questions.
Explanation:
The salt solution (brine) is a <span> hypertonic solution. It means that there is a higher concentration of dissolved salts outside of the cell, and a lower concentration of water than the cell. If the concentration difference is too great, the microorganisms cannot survive because the cells will be dehydrated and soon die, </span>
Answer/Explanation:
<u>Darwin's</u> <u>theory </u>of evolution refers to how the characteristics and features of a species can change over time. The process of evolution occurs due to <u>natural selection</u>. Natural selection is the mechanism by which organisms that have inherited beneficial traits are more likely to survive and undergo <u>successful reproduction</u>, meaning that variation is passed on to the next generation.
For example, in a species that suffers from overpopulation, organisms will likely have to compete for food and might <u>struggle to survive.</u> However, if a random change in the DNA sequence occurs, it could provide a beneficial effect to an organism that makes it more likely to find food and outcompete others. This makes that individual more likely to survive and reach mating age. This i<u>nheritable variation</u> could then be passed on to that individual's offspring.
