What conclusions can we draw from the lab about photosynthesis and cellular
GuDViN [60]

Answer:

Carbon dioxide and oxygen are recycled through photosynthesis and cellular

respiration forever unless something interrupts.

Explanation:

Photosynthesis and cellular respiration are two distinct and opposite metabolical processes undergone by living cells. They are opposite processes because one utilizes the products of the other as reactants.

Photosynthesis is a unique process to autotrophic organisms like plants. It is the process whereby plants synthesize their food in form of organic molecules (glucose) by combining Carbondioxide (CO2) and water (H2O) in the presence of sunlight.

The overall equation of photosynthesis is as follows:

6CO2 + 6H2O ------> C6H12O6+ 6O2

On the other hand, cellular respiration is the process whereby living cells obtain energy (ATP) by breaking down food molecules (glucose) using oxygen to produce carbondioxide (CO2) and water as products. The overall equation is:

C6H12O6 + 602 -----> 6CO2 + 6H2O

Based on the lab experiments, it can be concluded that Carbon dioxide and oxygen are recycled through photosynthesis and cellular

respiration because photosynthesis recycles/reuses the products of cellular respiration, which are C02 and H2O while cellular respiration recycles/reuses the products of photosynthesis, which are C6H12O6 and O2. This process occurs naturally in the environment and will continue to do so unless something interupts.

Option B is incorrect because light energy from the sun powers photosynthesis while option C is incorrect because photosynthesis transforms light energy to chemical energy while cellular respiration transforms chemical energy to thermal energy.

What effect might obesity have on blood pressure? Does obesity alone cause a person to be at risk for high blood pressure? What
Ugo [173]

Answer:

obesity increases blood pressure

Explanation:

This is because the high fat percentage in the body has lead to a build up of fat on the inside of arteries and this makes them thinner. the heart has to pump harder to get the blood around the body and through these, now smaller arteries. therefore yes having diabetes does increase blood pressure.

other factors which increase blood pressure are high stress levels, smoking, anxiety.
