It can't be lysosome or peroxisome..so, it should be spherosome, I guess

c) litter 

That explains how I missed it. Ah, no, ANY tip is better than no tip, and yours kinda made sense to me too (I'm not trying to flatter you, please :P)

How to solve assertion-reason type questions?

Okay, so the pattern is:
A - if both assertion & reason are right and reason the correct explanation for assertion
B - if A & R are right, but R is not the correct explanation for A
C - if A is right, but R is wrong
D - if both A & R are wrong.

While solving these questions, it's easy when the answer's C or D. But when it comes to choosing between A and B, i.e. when both Assertion & Reason are correct, I seem to be getting it wrong

My method of solving this type was to add "because" at the end of assertion and continue with the Reason to see if it makes sense.

Eg: A: Restriction endonucleases are also called molecular scissors or chemical scalpels.    
R: They attach themselves between the same two bases on the opposite strands and cause a break in two.

So, Restriction endonucleases are also called molecular scissors or chemical scalpels, because they attach themselves between the same two bases on the opposite strands and cause a break in two, which makes sense, so A is the right option.

However, while solving the following:

1. A: The branch of science which deals with the study of living organisms is called Biology
R: Living organisms always have cellular organisation, which may be unicellular or multcellular

My answer = B.   Given solution = A

2. A: The genetic material in Tobacco mosaic virus is RNA.
R: RNA is a type of nucleic acid.

My ans. - B        Given - A

3. A: The sum total of anabolic and catabolic activities is called metabolism.
R: Organisms with positive metabolism remain healthy.

Mine- B... Given - A

4. A: Night blindness is due to deficiency of vitamin A
R: Actually, the term vitamin means vital minerals.

My ans. = B           Given = A

These are just a few of the many questions I got wrong. So how am I supposed to go about solving these? And even in these specific examples, I cannot understand how the second sentence can be the reason of the first. Any help would be really appreciated.

Are admissions to KMC only by Manipal UGET, or can we get in through COMED-K UGET as well?

Awesome forum: Thank you SO much for all the great input!

1) To recall which side of the heart carries what type of blood --> "LORD" (Left Oxygenated, Right Deoxygenated)

2) Taxonomic Hierarchies --> King Philip Cried Out, "For Goodness' Sake!" (Kingdom, Phylum, Class, Order, Family, Genus, Species."

3) Purines - Since the word is short, so they're double ring molecules. (Adenine, Guanine)

Whereas, Pyrimidines - long word, single ring. (Cytosine, Thymine, Uracil)

[Also, "Crazy Glue":
Strongest bonds are between Cytosine and Guanine, strong like Crazy Glue (3 H-bonds), whereas the A=T only have 2 H-bonds. - not by me]

4) Trisomy Eighteen = Edward's Syndrome

Then mnemonics created by others and I find helpful

5) PROlactin stimulates the mammary glands to PROduce milk.
      Oxytocin stimulates the mammary glands to Ooze (release) milk.

6) Directions of pCO2 and HCO3 according to pH

ROME:
Respiratory= Opposite:
· pH is high, PCO2 is down (Alkalosis).
· pH is low, PCO2 is up (Acidosis).
Metabolic= Equal:
· pH is high, HCO3 is high (Alkalosis).
· pH is low, HCO3 is low (Acidosis).

7) Hepatitis: transmission routes:

"Vowels are bowels":
Hepatitis A and E transmitted by fecal-oral route.

8 ) Hemoglobin binding curve: causes of shift to the right = CADET
CO2
Acid
2,3-DPG (aka 2,3 BPG)
Exercise
Temperature

9)Types of blotting:

"SN0W DR0P":
· Match up the 1st word letter with 2nd word letter:
Southern=DNA
Northern=RNA
Western=Protein

10) Effects of Basophils & Eosinophils on allergy:

Basophils are "Bad-o-phils" because they contribute to our allergic reactions.
Eosinophils are "Easy-on-me-phils" because they counteract our allergic reactions.

That's it for now. Keep 'em coming!

 It's just another term for Water potential, technically speaking

 If the principle chain contains 2 or more multiple bonds, numbering is done in such a way that the multiple bonds get the lowest set of locants.

Therefore, here, pent-3-en-1-yne is preferred over pent-2-en-4-yne

Yep, it's true! Here's the official statement:

Wonder what the difficulty level of the mains would be =/?

Are NRI students eligible to attempt JIPMER 2010 entrance exam (for MBBS)? Or is it restricted to those students who completed their eleventh & twelfth grades in India only? [I'm am NOT asking if there's a separate NRI quota, but whether we can write the exam as part of the general category?]--Thank you
