Can the wing of butterfly and the wing of a bat be considered homologous organs? Why or why not?..
The wings of a butterfly, and the wings of a bat cannot be considered as homologous organs because they have different basic designs even though they perform similar functions, they are therefore...

Artificial selection to obtain cows yielding higher milk output represents : (1) Directional as it pushes the mean of the character in one direction
The correct answer is (1) Artificial selection to obtain cow yielding higher milk output will shift the peak to one direction, so this represents an example of Directional selection. In stabilizing...

How would you account for the following: (i) Cr^2+ is reducing in nature while with the same d-orbital configuration (d^4) Mn^3+
(i) Cr2+ is reducing as its configuration changes from d4 to d3, a more stable half filled t2g configuration while Mn3+ is oxidising as Mn3+ to Mn2+results a more stable...

Is the energy of an electron in 2s orbital same as of that in 2p orbital? Why?
No, the energy depends upon (n+l) values in an atom. Hence 2p orbital has greater energy than 2s.

Why is CO2 a linear molecule while SO2 a non-linear molecule?
In SO2 molecule there are two bond pairs and one lone pair of electron .Due to repulsion by lone pair its bond angle decreases from 120° to 119.5° hence it...

Distinguish between bonding molecular orbital and anti-bonding molecular orbital.
(i)The bonding molecular orbital has lower energy and hence greater stability than the corresponding antibonding molecular orbital. (ii) Just as the electron probability distribution around a nucleus in an atom is...
