Answer:
It is "The opening of flask is pointed in an unsafe direction"
Explanation:
The students were there in the lab to perform practical without obeying the safety rules. The most reasonable basis for teacher's warning here, in this case, is the flask which is pointed in an unsafe direction. It is not specified whether the flask is containing any chemical or not but even if it is empty, it might just fall and break and create injury to anyone present in the lab because, the students are also not wearing proper laboratory wear in accordance to the safety rules which include lab coats, gloves, eyewear, etc. Also, some Students have not tied their hair and more importantly the flasks carrying liquids are not labeled. All of these things might end up in a critical situation for which the teacher warned students about it all.
Answer:
No.This is because the amount of the chlorophyll; ls not a limiting factor of photosynthesis.
Explanation:
Generally the three factors are regarded as the limiting factors of photosynthesis.These are the CO2 concentration,light intensity,and temperature.Fluctuations in the availability of these factors affects the rate of photosynthesis.
When the rate of a chemical reaction depends on a lot of reactions for its progress.The rate of this reaction is determined or limited by the slowest in the reactions. This series of reactions govern this chemical reactions are the limiting factors. The one that is slowing down the rate of the reaction is said to limit it.
in the case of photosynthesis, a decrease in the amount of CO2,but no change in the amount of other factors would affect the rate of photosynthesis. This is applicable to other factors fluctuation too ,which limits the rate of photosynthesis
A) it must be human or e) its gametes must have 23 chromosomes
C.
The blood fluid contains less water, which will cause the water to go into the cells and make them swell up.
The best thing to do is this:
the subjects in the experimental group should be given large, daily dose of vitamin C while the control group subjects should be given a daily dose of sugar pills that are disguised as vitamin C.
The research can then observe the differences between the two groups.
