1. ### Sex linked diseases and lyonization in females

Suppose, there's a disease "D", which is an X-linked, dominant disease. Now, there's a female who possesses the allele for this disease in one of her two X chromosomes. (XDX) It's easy to say that since the allele for the disease is dominant, she'll suffer from it. Now, it's a well known fact...
2. ### Course of the Optic Nerve

We had a class on optic nerve today. Our teacher said that the optic nerve "originates" from the retina, and continues up till the commencement of the optic chiasma, and is, approximately, 4 cm long. My question is, Why is it considered to be a cranial nerve when it does not even originate...
3. ### Question related to molarity

No. I'm in high school. So, I don't know much about that. What specific situations are you talking about? .
4. ### Question related to molarity

Ammonia gas is passed into water, yielding a solution of density 0.93 g/cm^3 and containing 18.6% NH3 by weight. The mass of NH3 per cc of the solution is 1) 0.17 2) 0.51 3) 0.34 4) 0.68 I solved it using the molarity equation. Molarity = 10xd/MM where, x - % by weight d - density MM -...
5. ### Convex lenses

Ahh! I got it! Power is inversely related to focal length. Now, because the combination is "more" converging (more power), its focal length will be less. :headbang: I think it's correct now. Thanks! :oldsmile:
6. ### Convex lenses

Homework Statement A thin double convex lens of focal length f is broken down into two halves at the axis. The two haves are then combined, as shown in the figure. What will be the focal length for the arrangements...
7. ### Relative stability of ortho and para isomers

Generally, in organic reactions, the para isomer is found to be more stable (as it is symmetrical) because of which it is produced in greater amount than the ortho isomer. However, there are some exceptions also, for example, in some reactions the less sterically hindered ortho isomer is...
8. ### Dipole in an external electric field

The direction of the resultant of A x B is just opposite to that of B x A...
9. ### Dipole in an external electric field

Homework Statement Why isn't the expression for torque on a dipole kept in an external electric field ExP? Why is it PxE? No such indication has been given in any of the derivations, that it is mandatory for it to be PxE, so why can't it be ExP? 2. The attempt at a solution Is it all about...
10. ### Kirchhoff's Loop Rule Problem.

So, the mistake lies in that "assumption" itself. It messed everything up. Thanks a lot!
11. ### Kirchhoff's Loop Rule Problem.

What would have happened if there was a question with the same circuit diagram and a cell with emf (E) 12 V was present there?
