Answer:
A- making an observation and asking a question
Explanation:
Scientific method is the set of basic norms that must be followed for the production of knowledge that has the rigor of science, that is, it is a method used for research and proof of a given content. The part of the scientific method being shown in the question above is "making an observation and asking a question", because the question shows that the forest engineer wondered why a forest had mature hemlock and very few young hemlock, so that If an engineer could ask this question, he would have had to observe this before.
Explanation:
if solute is 43% inside the cell then water is 57% (100%-43% = 57%)
outside; 100% - 60% = 40% water
it is hypertonic because water concentration is high inside the cell than outside, hence water flows to the outside of the cell.

Explanation:
Coelacanth is a special type of fish called lobfin. It is significant in evolution because it is a missing link between fishes and the amphibians. They evolved into the first amphibians that lived on both land and water. These were the ancestors of modern day frogs and salamanders.
Coelacanths are important for understanding the transition from water to land. Coelacanths were thought to be the ancestors of tetrapods a four-legged, land-living animals, but recent discovery of the coelacanth genome suggests that lungfish are actually more closely related to tetrapods.
