C.all answers are sources of error
D. Lap equipment is not always identical (they can vary)
E.people observe things slightly differently and can make mistakes
Answer:
The correct answer is option C. all answers are sources of error.
Explanation:
The major source of error in any scientific experiment includes instrumental error which means that instruments or lab equipment are not accurate or calibrated properly or not able to determine the experiment.
It also includes a human or manual error in observing experiment observation or analyzing or calculating the results. Evolutionary errors are also one of the major sources of error that include humidity, temperature, wind, or light.

Calculate the rate of photosynthesis(mm/hr) for Elodea if when measuring net photosynthesis, the water level moved up 5 min and, when measuring cellular respiration it took 20 minutes for the water level to move down 1mm.
63mm/hr
57mm/hr
67mm/hr
61mm/hr
52mm/hr
Answer:
Net photosynthesis- 3mm/20min- 1.5mm/10min
Cellular respiration- 1mm/15min- 0.66mm/10min
Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)
Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr
As we are measuring rate of photosynthesis in hr ,we should multiply gross photosynthesis with 6 (as we measured gross photosynthesis for 10 min).

A) It is composed of proteins and carbohydrates
B) It has the same permeability to all substances found inside or outside the cell.
C) It is a double protein layer that doesn't allow things to pass through it.
D) It selectively regulates passage of materials into and out of the cell..
D) It selectively regulates passage of materials into and out of the cell.
The plasma membrane in a living plant cell is composed of a double lipid layer that gives it hydrophobic character and acts as a semi- permeable barrier. The partial permeability of the substances allows regulating the passage of substances from and to the interior of the cell. At the level of the plasma membrane there are several mechanisms and transport to allow the entry of substances needed for the cell or the output of synthesized products or metabolic waste, thus regulating the passage of substance in a selective way.They keep toxic substances out of the cell.They contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products.Therefore, correct option is D)
