okie...forget the ratio...we see that the grandparents are normal so there genotype is either TT or Tt...it should be Tt cuz when offsprings are showing 'abnormality' it means that by crossing we should get tt which is ONLY possible when the grandparents are Tt and Tt. get it?
Sorry for bothering.. i know am asking a lot of questions. The question says that normal individuals are indicated by white symbols.. but the grand-parents are indicated by black symbols, showing that they have a defect. So how does it make them heterozygous, since they have an abnormality??
Grand parents are black! Check it out below..it's completely fine...i don't mind
grandparents are normal..they are white not black
The small intestine will absorb all the sugar from food and hence, blood vessel B will have the greatest concentration of sugar!
thanks please answer the other one
The removal of urea from the blood is not excretion, but a process of filtration carried out by the kidneys! By definition, excretion is the removal of waste products from the body (As in, out of the body). So the only answer here is the removal of undigested food from the anus (C). Hope this helped..
i know but in the mark scheme it is the removal of urea from kidney
Oh yeah.. I was wrong! Did some research now.. removal of undigested food from the anus is egestion. Removal of urea from the blood is excretion coz urea is a waste product. Thank u for clarification btw, I would've gt it wrong tomorrow!
Thx so much!!!!
thank you also very muchOh yeah.. I was wrong! Did some research now.. removal of undigested food from the anus is egestion. Removal of urea from the blood is excretion coz urea is a waste product. Thank u for clarification btw, I would've gt it wrong tomorrow!
Water will diffuse through the potato into the concentrated sugar solution. This is because osmosis/diffusion occurs from a region of high concentration to a region of lower concentration (down the concentration gradient). Hence, the water will move into the concentrated sugar solution (since there are more water molecules outside the potato) and its level will decrease while the level of sugar soln will increase. So the answer here is C..Assalamulaikum ppl,
