Chelcy10:
yea, thumbs up, it's option A, cos d gene dat determines sex is found in d Y chromoson in d female. So sex-linked character can not be transfered directly frm father 2 son.

The male chromosome is XY while female chromosome is XX,the males can inherit sex linked characters only from their mothers.

Obinnau: I heard that its hard for them to admit non indegenes into Med skul, also I don't know if its conducive for learning.

dnt worry abt the admission,just pray to God abt it,am sure he wil answer u.

A,D,D,C,A.Hi all. Also a medical aspirant.

U are welcum,u scored 4/5,u missed number 4,it is pale green.NICE TRY.@daviyd

If u can continue lyk diz 4 d next 20 dayz,u guyz will be 65% ready 4 d exam.let me drop some questions.The drying agent 4 ammonia is...............which gas law is equal 2 work done.Double fertilization occurs in...............d reverse of esterification is..............d ores 4 tin and aluminiun is

Prince adebayo: U are welcum,u scored 4/5,u missed number 4,it is pale green.NICE TRY.@daviyd

yes,because H2S is a reducing agent and reduces the Fe3+ to Fe2+.... Silly me :-D

aliandro: If u can continue lyk diz 4 d next 20 dayz,u guyz will be 65% ready 4 d exam.let me drop some questions.The drying agent 4 ammonia is...............which gas law is equal 2 work done.Double fertilization occurs in...............d reverse of esterification is..............d ores 4 tin and aluminiun is

CaO,Boyle's law,flowering plants,hydrolysis, cassiterite or tin stone (SnO2)and bauxite Al2O3

i what u all 2 hav faith dis yr is ours

Is there anyone that choose unilorin or unilag

larri: ADBBA

u scored 4/5,number 1 is B.

endur4long: i what u all 2 hav faith dis yr is ours

yeah,our time has come

Prince adebayo: u scored 4/5,number 1 is B.

I think number 4 is low pressure and high VOLTAGE.... Please explain number five for me. God bless you. BTW,what school did u opt for?

Daviyd: I think number 4 is low pressure and high VOLTAGE.... Please explain number five for me. God bless you. BTW,what school did u opt for?

yeah,it is high voltage and low pressure but dat is hw it is in my physics past question.

Daviyd: I think number 4 is low pressure and high VOLTAGE.... Please explain number five for me. God bless you. BTW,what school did u opt for?

forward bias is a type of battery connection in a PN junction in which the +ve terminal of battery is connected to the P type semiconductor nd vice versa,the layer btw the P and N is d depletion layer which wil narrow or reduce.

Daviyd: I think number 4 is low pressure and high VOLTAGE.... Please explain number five for me. God bless you. BTW,what school did u opt for?

Hello guys,pls i need help with dis question.I'm confused with the answer being b or c.Pls anyone that answers it should do so with a little explanation.Thanks. Which of the following is involved in secondary thickening in plants? A. Collenchyma and xylem cells. B. Vascular cambium and collenchyma cells.C. Vascular cambium and collenchyma cells. D. Cork cambium and sclerenchyma.

I think its D.
REASON: Cambium is a tissue which gives rise to secondary growth in older dicot roots. Sclerenchyma is made of dead cells in which the cell walls are heavily thickened.
So I think dis two are involved in the secondary thickening of plants.

Is this question frm jamb 2012 biology? If so,sumtin is wrong wit the option c,the answer is option 'C' vascular cambium and cork cambium,the parenchyma,sclerenchyma and collenchyma cells are found in d cortex for strengthening the stem,cambium is for secondary growth/thickening.

Prince adebayo: The male chromosome is XY while female chromosome is XX,the males can inherit sex linked characters only from their mothers.

Tnx brother, I must av thought it dsame as in some aves and insecta group, where females has XY and male XX.

I support ur ansa though I failed it last year. Guys what was ur score last year? Mine was 224?

nice thread.. hope to get more questions...i rep AAU

Kk.Thanks guys,rilly grateful

Prince adebayo: OAU nd u?

UNIZIK. Back to the question does the depletion layer widen when its reverse biased?

Daviyd: UNIZIK. Back to the question does the depletion layer widen when its reverse biased?

Yeah

Obinnau: I support ur ansa though I failed it last year. Guys what was ur score last year? Mine was 224?

I thought as much. Mine was 236. Back then I felt so angry and cheated. But in retrospect,I even wonder how I made up to that. What school did u opt for?
