The correct answer is option (C) One student measures liquids for the experiment by holding the flask up at eye level. The other student measures liquids for the experiment while the flask sits on the table. Measuring liquids by holding the flask at eye level is the greatest amount of error in the experiment.
When liquid is being measured in a flask, the liquid shows a curve downwards which is called the meniscus. For measuring the transparent liquids, the lower meniscus touching the graduation of the should be considered and for measuring the colored liquids, the upper meniscus touching the graduation of the flask should be considered. When, the measurement is done by holding the flask at eye level there is always an error as it should be kept on a flat surface and measured by eyes directly leveling with the liquid. This gives a correct measurement which was done by the other student. Thus, one student measuring the liquid by holding the flask at eye level will have a wrong measurement and the other student measuring the liquid while the flask sits on the table gives the correct measurement and the results of the experiment will vary.
As photosynthesis is a process that requires sunlight, the rate of this process will be 0 in a room without any light.
However, even if the dark room has very little light, it may still not be enough for photosynthesis to occur. This process requires certain levels of sunlight.
Answer:
Its is a lysosomal storage disease!
Explanation:
<u>Hurler syndrome:-</u> is also known as mucopolysaccharidosis-I .
It Is due to the mutation on chromosome 4 .
There is a lack of of enzyme called alpha-L-iduronidase.This enzyme is present in lysosomes
It causes accumulation of mucopolysaccharides because of the absent of the enzyme in the lysosome
<u>Hunter syndrome:- </u>is also known as mucopolysaccharidosis-II
It occurs due to mutation in iduronate-2-sulfatase (IDS) gene.It is an X-linked disease
