When Jacob is running, his heart beats 23 times in 10 seconds. What is Jacob's heart rate in beats per minute (bpm) while runnin
2 answers:
Answer:
138 bpm
Explanation:
A minute has 60 seconds. You have 23 beats in 10 seconds. You could do a simple multiplication by 6 to get to the 60 seconds you need or you could say:
23 beats .......... 10 seconds
x beats .......... 60 seconds
x = 138 bpm
I think you got the point. Desires time is 6 times larger, so is the number of beats.

Compound microscope
<h3>Further explanation</h3>In 1665, Robert Hooke used a compound microscope to observe cells. Hooke observes the cell walls of dead plants (in the form of cork) when they appear under a microscope. He named it the cell because it looked similar to a cellula or small room inhabited by monks.
Development of microscopy:
- 1590: Hans and Zacharias Janssen, as Dutch lens grinders, mounted two lenses in a tube to produce the first compound microscope.
- 1660: Robert Hooke published <em>Micrographia</em>, containing detailed observations of biological materials made with the best compound microscope.
- 1676: Anton van Leeuwenhoek was the first person to observe a live cell under a microscope, i.e., the algae Spirogyra.
- 1931: Ernst Ruska constructed the first electron microscope. With the invention of the electron microscope, many infectious agents smaller than bacteria could be seen.
Until now, we can see how important the use of microscopes, especially in microbiology, that is the study of microorganisms.
