<span>The answer is C. This is because the discovery of
the cell and its organelles began with the discovery of the microscope in the
17th century. As powerful microscopes were developed over time, the
cell organelle become discover-able by different scientists. As other developments emerged, they enabled tagging of
elements, hence monitoring of biochemical pathways also became possible.</span>

Answer:
Some examples of important nonliving things in an ecosystem are sunlight, temperature, water, air, wind, rocks, and soil. Living things grow, change, produce waste, reproduce, and die. These living things interact with the nonliving things around them such as sunlight, temperature, water, and soil.
Explanation:
Nonliving factors determine what living things can be supported in an ecosystem. The living creatures in a habitat affect the nonliving elements within the community. For example, plants can affect soil chemistry or certain algae can influence water chemistry.
I would go with D, speaker. A poem is written by an author, but the author isn't always the speaker.
Answer:
y = 
Explanation:
3x + 5y - 15 = 0
So we want to get it in the form y = mx + b
Subtract 5y from both sides;
3x - 15 = -5y OR -5y = 3x - 15
Divide both sides by -5
y =
