Circadian rhythms ....its just behavior that is repeated over 24 hours
Well, ask yourself, "Do I try hard enough?" "Was it the best I could do?" And well if the answer is yes, then you have nothing to stress out about too much. Maybe talk to your teacher and ask for extra credit. Get tutoring. Talk to a guidance counselor. If none of that helps, well then you're just not the best at the subject, but just try your best. In the future, you won't even remember about all those grades! Coming from a 6th grader, the beginning of the year was super hard. I'm not the best at math, but I'm very good at Language Arts. Everyone has their own weaknesses and strengths. Don't worry about it.
Answer:A
Explanation:
It absorbs carbon dioxide
Answer:
Aldehyde has C=O bonded to atleast one H atom while Ketone has C=O bonded to two carbon atoms
Aldehyde - galactose, glucose, glyceraldehyde, fructose
Ketone - Trioses, Tetroses, Pentoses, Hexoses
Explanation:
Similarity
Both the aldehyde and ketone have C=O group
Difference
In aldehye the C=O group require atleast one hydrogen atom or the functional group in aldehyde is -CHO
while in ketone the function group is C=O only that is bonded to two carbon atoms.
Example
Aldehyde - galactose, glucose, glyceraldehyde, fructose
Ketone - Trioses, Tetroses, Pentoses, Hexoses
It's both! Scientists really can't agree on it.
