I need a partner!! Pls help Plan an investigation to examine how heart rate changes during and after an exercise is performed for two different periods of time.

How does heart rate change during and after an exercise is performed for two different
periods of time?

In the space below, develop a hypothesis that will test the question.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )

geologic time scale (for gradpoint) =)
