Answer:
3: A device that uses radioactive fluid to determine the active areas of the brain
Explanation:
A positron emission tomography (PET) scan is an imaging test that helps reveal how your tissues and organs are functioning. A PET scan uses a radioactive drug (tracer) to show this activity. This scan can sometimes detect disease before it shows up on other imaging tests.
Depending on the type of exam, the radiotracer is injected, swallowed or inhaled as a gas. It eventually accumulates in the area of the body under examination. A special camera or imaging device detects radioactive emissions from the radiotracer. The camera or device produces pictures and provides molecular information.
The general formula for calculating the net value is this
net = gross - deductions
The deduction is the respiratory rate
The net primary productivity is given
Solving for the gross primary productivity
gross = 2000 + 1000
gross = 3000 <span>mg c/m2/day</span>
Answer:
villi is used and is very imp as it has structure like finger type which help for increase in surface area for more absorption and less wastage of water/minerals
Answer:
Stage two: carbon fixation
The ATP is broken down to release energy which is used to combine hydrogen (from the light reactions) with carbon dioxide to produce sugar. The reactions of carbon fixation are controlled by specific enzymes.
