Answer: c. I want to improve my grades by working a lot harder than last year.
Explanation:
The answer c) would be the best goal for her because in that way after improving her grades by working harder she will see and decide which technique is best for her good grades.
Other options in the question can be harmful to her goals because they can make pressure on her and demotivate her. She must try first to work harder than the last year and in that way, she will see how she can set the new goal.
Answer:
The false statement is-Our body has no mechanism to stabilize free radicals.
Explanation:
Free radicals are the atoms produced in the cell mainly due to oxidative stress. For example, oxygen splits into an atom having an unpaired electron. So these atoms having unpaired electrons are called free radicals.
Free radicals are responsible for damaging DNA and causing cancers in the body. In our cells antioxidants are present which checks the presence of free radicals in the cell.
They stop the free radicals chain reaction and eliminate the free radicals in the cell by giving an electron to free radicals without getting destabilized. Therefore our bodies have a mechanism to fight with free radicals.
In a sample of double-stranded DNA, if the nitrogenous base guanine is 19%, then the nitrogenous base adenine will be 31%
Explanation:
In a double-stranded DNA, the four nitrogenous bases bind and pair together. The purine bases guanine (G) and adenine (A) pair with pyramidine bases cytosine (C) and thymine (T) respectively. The pairing will be between G-C and A-T bases.
According to Chargaff’s Rule, the percentage of each nitrogenous base will be equal in a pair. So the percentage of G will be equal to percentage of C and the percentage of A will be equal to percentage of T.
So if the guanine percentage is 19%, then applying Chargaff’s rule, cytosine will also be 19%
The remaining 68% will be shared with the adenine and thymine pair, of which adenine will be of 31% according to Chargaff’s rule.
