Answer:
-1.9mL/min
Explanation:
The rate of O₂ production can be calculated by the formula
= ( Final volume - initial volume)/time(min).
From the graph provided and attached below, the rate of O₂ production or rate of photosynthesis at light intensity of 8 is about 3.75 mL/min.
The rate of O₂ production is taken as the rate of photosynthesis. It is expected to progressively increase from light intensity 0 as light intensity increases. However, at very high light intensity, the rate slows down as water becomes limiting and the stomata closes in order to conserve water.
Question in order
Experiment 2: Respiration in the Dark
Calculate the volume change for respiration in the dark. As you already saw from earlier questions,
oxygen production is fairly constant. You will not need to calculate the individual volume changes.
Just subtract the original volume at 00:00:00 from the final reading at 00:02:00. Record your answer
for use in a later question.
<em>Note: depending on when you started the timer there is a range of possible answers. Pick the answer that is closest to this</em>
What was the volume change for respiration in the dark?
Correct answer:
-1.9 mL/min
Answer:
The correct answer would be large NA
The resolution of a microscope is defined as its ability to distinguish two closely placed points as different entities.
The NA or numerical aperture of an objective is defined as the ability of a microscope to gather light.
NA determines the resolving power of the microscope that is, the higher the NA the higher will be the resolving power of the microscope.
However, the total resolution of any microscope also depends upon the NA of the substage condenser.
Answer: B). CO₂
Cellular respiration is the process of conversion of food energy (glucose) into chemical energy (ATP). Oxygen and glucose are the reactants in the chemical reaction of this process and carbon dioxide and water are the products.
Exchanging oxygen and carbondioxide between air and lungs because it just involves breathing system but everything else involves hormones.........
HOPE IT HELPS !!!
Answer:
C. It is driven by natural processes like rock weathering and nitrogen fixation.
Explanation:
It has been discovered that eutrophication occurs through a gradual increase in the deposition of phosphorus and nitrogen and other plants nutrients in the water bodies.
This will allow the maximum growth of algae on the surface of the water.
It has been discovered that eutrophication is not good for the water bodies. This is because, the excess growth of algae on the surface of the water will prevent the sunlight from penetrating the water, thereby preventing the plants inside the water from making use of the sunlight to carryout photosynthesis. Also, it will prevent oxygen from entering, thereby depriving the organisms in the water from having the necessary oxygen needed for respiration.
