Answer:
One stated possible negative effect of a warming trend on earth is that the polar ice caps could melt.
Explanation:
Specification on how this will have a negative impact on the living environment is that it will cause sea levels to rise this is negative because: tsunamis will become more severe and damaging to land. Rain storms will have severe floods then what we have now.
Hope this helps.
Answer: knowing that the number of adenine will be always equal to the number of thymine.
Explanation:On the basis of base pairing rule, the purine bases bonds with the pyrimidine bases. This takes place as the configurations of pyrimidine and purine bases permit formation of hydrogen bonding between the two.
The base pairing rule suggests that the pairing of adenine takes place only with thymine and pairing of guanine takes place only with cytosine. Two hydrogen bonds are produced between an adenine and thymine base pair, while three hydrogen bonds are produced between a guanine and cytosine base pair.
I think the answer is due to ph. levels in the soil
<span>The lac operon has three genes that encode for proteins that break down lactose into galactose and glucose. When there is no lactose around, it wouldn't make sense for the prokaryote to make these proteins as it would be a waste of energy. So, when there is no lasctose around, the lac repressor binds the operator region of the operon, which inhibits RNA polymerase's ability to bind and start gene expression. However, when lactose is available, it binds to the lac repressor and deactivates it via allosteric inhibition. Once the lac repressor is gone, the genes can be transcribed into mRNA which can be translated into proteins which can go and break down the lactose. </span>
