Noooo!! Just have it in mind there are some people with higher marks, upper grades than this.. Don't just sit down. I wish you best of lucks.

Congrat bro, i pray it won't be a waste.

I glorify God. I just checked my score, i got 283. Gutted I couldn't meet my aim, 300+. Perhaps I couldn't meet felix00. I'm waiting for the Gurus in the house.

Congrat felix00, all round success IN JESUS NAME.

The way the question were fair, repeated and most candidates bragging of high score is making me uneasy. Surely they won't send our actual score, i hope to be among the lucky ones.

felix00:
dilute ba(no3)2 was added to acidify an unknown sol, which forms white PPT with AgNo3 which is soluble in NH3. the unknown solution contains

C) so3^2-
D) No-

This came out today.

Felix00 please do tell us when you get the result, the time difference the medium (phone or email). Thank you.

Please who wrote utme today? Please do notify us when you get your result.

A since voltage is the same just use p=v2/R and v is same so it will be p1R1=p2R2 and pi/p2=R2/R1

Hmmmmmm! More like P inversely proportional to R ba? But please How did you get the hint of their having equal voltage. Because they are in Parallel?

More likely A, sex-linked only affect X-chromosome. I don't think it's possible with father and son XY.

I'm not sure of my answer. But I know the pituitary is the master gland and the pancreas doesn't stimulate............its just an insulin production site.

Stanley what's the correct answer?

You could be right, biology is a very scary subjects to me with the twists and turns. We have to be sure.

I checked various past questions, i checked Pre-degree outlets it's not in order with my note, what would you pick if you were to find it on the hot seat??

Red blood cell, is it destroyed in the Liver or spleen?

Optimist1998:
Pituitary gland

Wtf! I couldn't find any line about this in my text.

ColdSweat:
A. Convergent evolution

Optimist1998:
like coldsweat said..... its convergent.

ColdSweat:
A. Convergent evolution

Past question says No!

I decided to share this, i missed it at first sight.
As water is cooled from 10°C to 2°C, its density A. Increases B. Decreases C. First decreases and then increases D. First increases and then decreases.

My camera couldn't cover it all.
**The wings of a bat and those of a bird are examples of A. Convergent evolution B. Coevolution C. Continous variation D. Divergent evolution. 2011 Q50.

Optimist1998:
Divergent evolution: Different species of an organism arise from one father/ancestor.
Convergent evolution: Similar organisms but completely different ancestors. For example We look alike but we're actually from different parents. we only look the same because we occupy similar habitats--planet earth.
Hope you get the picture?

Thank you, the past question chooses something different from my note, so I had to ask. However, I'm viewing in a way of body structure. For instance a toad can respire through it skin while pisces respire through the gills. In short it's entirely two different structure that serves the same function. I suggest this is convergent but past question says NO!. What do you think?

Optimist1998:
After how many weeks I've finally finished that insipid book . I don't think I can remember any thing apart from Tayo and Vanessa offcourse

Hahaha.. I'm not alone.

It seems felix00 and Nuel25846 opinion on the mock exam contradict.

Please I would very much like it if anyone explain to me ; convergent & divergent evolution.

Continue..

The novel seem like a burden to me, too many things to commit to memory.

felix00:
I think for it to serve as a wateva mirror it must be enlarged and erect.. So there is only one spot u get dat kind of combo I.E btw the pole and principal focus of the mirror.

You're right. Between F & P the Image is formed behind the mirror. Hence, it is
—Virtual.
—Since it is virtual, it must be erect. &
—Magnified.

Genius101:
using R=ut got 0.8m

Range?? I didn't think to that at first. The "horizontal" made it clearer.

Optimist1998:
You mustn't forget that water and steam are two different states of matter, so if you're referring to water; ice is less dense than water--> the reason why ice cubes will float in your cup of water. Steam is the least dense of them all.
The answer to that question is A.

Option A, for volume to decrease it means corresponding increase in density. With what you've explained density in decreasing order would be water➡ice➡steam. Is that it?

Optimist1998:
Steam occupies a larger volume when compared to ice. Since it has more volume, density would be lesser than ice.
Density= mass/volume
more volume less density
Higher density lower volume.
Ice has less volume more density than steam
Have you seen ice floating on steam before?
You should ask the author this question

Thank you the point he made is, ice float on water cos of it's lower density; higher volume. Please check the past question year '97 Q25. What answer do you get?

Hello! I need help my physics textbook wan spoil my life, one says ice has more volume; less density than steam the other book contradicts. Anyone??

So, we have many OAU pharmacy aspirants here? I'm Nervous already.

Since molecules make up matter (solid, liquid or gases) D is most appropriate I think.
