why cant male bees be genetically identical?
View attachment 12913

Because they develop from eggs. Even though the eggs are unfertilised, since the eggs are made by meiosis, you have genetic variation and none of the eggs are same, and therefore neither are the male bees.

sucrose is a reducing sugar right? so how would u xplain this, the ans is AView attachment 12919

Sucrose is NOT a reducing sugar; however, after it is hydrolyzed, it produces glucose and fructose. Both of which are reducing sugars.

Nibz Irfan1995

Yes, it is. So?

The one without the centriole should be a correct option. So it's either A or C.
Diploid is 8.
Answer C.

 

[XPFMember]

Yes, it is. So?

oops sorry...i saw it wrongly and i thought the correct option had a no for cellwall sorryyy

I don't see what is confusing you. They are also saying that the cell wall is present. What is confusing me is that they are saying there are no centrioles???? During metaphase, the centrioles are the one which produce the spindle fibres, no?

It's HIV. Mary Jones give an example of Zidovudine and says, "(e.g. zidovudine is similar to the nucleotide that contains the base thymine). Zidovudine binds to the viral enzyme reverse transcriptase and blocks its action. This stops the replication of the viral genetic material and leads to an increase in some of the body's lymphocytes."

No, not in plant cells.

plants do not contain centrioles i forgot that fact...and plus i mistakenly saw the wrong option...and thought that the correct answer states there's no cell wall..my mistake

just hope paper goes welll inshaAllah...
2 hours stilll ....

jazakAllah khairen @everyone for helping...
