NEED HELP ASAP, WILL GIVE BRAINLY

Biology
1 answer:
Bingel [31]3 years ago
5 0

Answer:

4. (answered below); 5. 66.2; 6. (answered below)

Explanation:

4. The individual's heart rate increased because the individual needs more oxygen supplied to their muscles so the heart has to pump the oxygenated blood through the body at a faster rate.

5. Take average of the number of the pulse before exercise:

(68 + 70 + 54 + 64 + 75) / 5 = 66.2

6. Different individuals are different sizes and are in different states of health. An individual who is more physically fit will have a slower rate rate because their heart muscle is "exercised" or worked more and pumps blood more efficiently.

<em>between </em><em>an </em><em>animal</em><em> </em><em>cell </em><em>and </em><em>a </em><em>plant </em><em>cell </em><em>there </em><em>are </em><em>some </em><em>parts </em><em>that</em><em> </em><em>are </em><em>similar</em><em> </em><em>and </em><em>carry </em><em>out </em><em>the </em><em>same </em><em>function </em><em>like:</em>

<em>both </em><em>have </em><em>a </em><em>cell </em><em>membrane</em><em> </em><em>which </em><em>selects </em><em>what </em><em>goes </em><em>in </em><em>the </em><em>cell.</em>

<em>both </em><em>have </em><em>cytoplasm</em><em> </em><em>which </em><em>holds </em><em>the </em><em>protoplasm(</em><em>the </em><em>living</em><em> </em><em>part </em><em>of </em><em>the </em><em>cell)</em>
