Answer:
B. Triazine-resistant weeds were more likely to survive and reproduce
Explanation:
According to darwin's theory of evolution, variation is already present in some members of a population and this variation lets them survive in the adverse condition and those who do not have that variation which helps in survival are lost with time.
So as before using triazine herbicide the major population of the weed were not resistant to this herbicide so in the first few years the nonresistant weeds were lost and only resistant weed which was very less in number survived.
So after several years these resistant weeds reproduced and transferred their gene to their offsprings and became predominant in the field. Therefore the correct answer is B.
false
Explanation:
no because there is 2 hydrogen and 2 oxygen
that would be hydrogen peroxide but water is H2O
Answer:
I think C option ✔️ ✔️ correct
If the totaling of bromine to cis-cinnamic acid uses the
same mechanism or device as the addition to trans-cinnamic acid, addition of
bromine only transpires on the top (syn) and not the bottommost face (anti). Therefore,
bromine added to cis-cinnamic only adds to the same face (syn addition) as a
result producing only threo dibromides.
