The purpose of this lab was to investigate whether veins affect photosynthesis rate. It was predicted that having veins would decrease the rate because chloroplast might be less frequent due to the vascular tissue. For this experiment‚ 4 groups were set up: veins and no veins in CO2 solution‚ and veins and no veins in distilled water‚ the distilled water groups served as controls. These 4 groups were placed under a light bulb in order for photosynthesis to occur. No disks experience movement in the

Introduction In this lab‚ I looked at how exercise affects a person’s heart rate (BPM)‚ systolic pressure‚ diastolic pressure‚ and Mean Arterial Pressure (MAP). Heart rate is measured by beats per minute while systolic and diastolic pressure are measured by millimeters of Mercury.

We found out that heart rate and systolic pressure were highest right after and during exercise‚ while diastolic pressure and
