When Jacob is running, his heart beats 23 times in 10 seconds. What is Jacob's heart rate in beats per minute (bpm) while running? 135 bpm
136 bpm
137 bpm
138 bpm

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.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
