Urethra

 

[funky brat]

It was rectum,anus is the end part,and since it was a bit above it was rectum.I made a silly mistake though too,labelled the sperm ducts seminiferous tubes,even though i knew they were sperm ducts....

But don't you think they'll just consider both anus and rectum correct? :/

But don't you think they'll just consider both anus and rectum correct? :/

If i recall correctly,there was a similar past paper question where in ms they stated rectum(R Anus) or vice versa.Anywho it was above the anus so it had to be rectum,but lets hope for the best.

I think so.I said they may not reach very far or may not be carried at all,and less time means less pollen given out which reduces chances of pollination

[Dream.Eater]

Hi
Can anyone explain to me the logic of part iv of the question. The ms has given a confusing answer....

 

[asadalam]

plz hepl in this simple logic

X=2,8,5 means it has a valency of -3 (8-5=3)
Y=2,8,7 means it has a valency of -1 (8-1=7)

We will exchange valencies
Answer will be A XY3

This is a concept. Since the temperature is constant, the Ek will remain constant, and since there is a change in state, the Ep changes

 

[Abdul Hanan]

inshallah

 

[Dream.Eater]

plz hepl in this simple logic

Ans to that is A since X forms X3- and Y would be Y- so cross the charges you get XY3

 

[Dream.Eater]

This is a concept. up to now e the temperature is constant, the Ek will remain constant, and since there is a change in state, the Ep changes

Wow..never thought abt that. Thanks a lot bro!!
How were the exams upto now?
