Coal mining produces not only air pollution but solid waste; ash and flue - gas desulferization sludge ( look it up ), which contains toxic arsenic and radioactive uranium among other heavy metals. Water becomes polluted with these harmful substances through mountain top removal mining and so underwater creatures are poisoned and plants absorb deadly substances and die, which also contributes to the aquatic organisms death as the plants may have been a food source.
Answer:
the answer would probably be 75%
Explanation:
If you do a punnet square it will show the results.
Through analysis of ice cores, scientists learn about glacial-interglacial cycles, changing atmospheric carbon dioxide levels, and climate stability over the last 10,000 years. Many ice cores have been drilled in Antarctica.
Answer:
"A protein's specific shape determines its function. If the three-dimensional structure of the protein is altered because of a change in the structure of the amino acids, the protein becomes denatured and does not perform its function as expected."
Explanation:
Just finished my research, I hope the answer above can help you
Answer:
recombinant DNA
A strand of DNA formed by splicing DNA from 2 different organisms is called recombinant DNA
Explanation:
Using the techniques of recombinant DNA technology, certain enzymes known as restriction enzymes capable of cleaving double stranded DNA in the plasmid of bacteria genomes (other organisms like eukaryotes can also be used) are used to obtain specific sequences of DNA bearing desirable traits in the both organisms.
Once the two DNA fragments have been obtained, another enzyme known as DNA ligase is used to seal the point of splicing, thereby constructing a single DNA from the two organisms.
This single DNA is known as Recombinant DNA
