The process is slow but it releases energy..http://www2.uni-siegen.de/~pci/versuche/english/v44-3.html
Is the ans C?

Two hetrogyzygous with recessive r and dominant R characteristics r crossed: Rr x Rr
Offspring's genotype will be RR, Rr, Rr, rr (try it with a punit square)
Now the question is What is the probability that one of the offspring produced will show recessive characteristic as homozygous (rr). Through the punit square we know that this is possible (Infact 100% possible) so the probability is 1 (full possibility)
hope u get it now

may/june 2007 question 3 what is the answer and why?
is it A? (chemistry)

hi,
i will explain it, even more just in case
every reaction needs an activation energy and so we have to burn the magnesium first in order to start the reaction, however when the reaction starts it will then release energy (exothermic) also note that the energy released is more than the energy given at the start and so it is exothermic.

how did you guys find the exam?

i got the cross too!!! ok so you mean the question is that after the cross one should show homozygous characteristic and we are getting one !! that is why the probabililty is 100% thanx so nice of you

can someone tell me what a lag phase, log phase, and the other phases are that occur in a graph that shows the growth of a population
