Answer:
"Energy flows in one direction, matter recycles."
Explanation:
Matter "returns" to the environment by the deutucators. Energy comes from the sun and is transmitted to higher trophic structures.
Answer:
Thymidine dimers is likely to be repair as soon as it is originated but if left unrepaired then it causes frame shift mutations.
Explanation:
In case of Bacterium if UV irradiation induces covalent linkage of two thymidine present adjacently to each other or on a single strand to make thymidine dimers.
These either excised via DNA repair enzyme like Endonuclease V and the proof reading activity of DNA polymerase I enzyme help in incorporation of nucleotide by taking the unmutated original strand as a template.
These dimers if not excised before second round of replication than the sequence of newly synthesized strand will be altered. As DNA polymerase III enzyme read thymidine dimers as single thymidine nucleotide and incorporate only 1 adenine in the newly synthesizing complementary strand which results in frame shift mutations
It is the mutation in which reading frame of codons is shifted or altered due to deletion or addition of a single nucleotide.
The answer is a stem cell. there is the unspecialized cell that generates or capable of renewing themselves through cell generation. Stem cells are important for living organisms for many reasons. In the 3- to 5-day-old embryo, called a blastocyst<span>, the inner cells give rise to the entire body of the organism, including all of the many specialized cell types and organs such as the heart, lungs, skin, sperm, eggs and other tissues.</span>
Pathophysiology is a sub discipline of physiology that deals with the study of mechanisms of disease. Pathology describes the abnormal or undesired conditions while pathophysiology entails explaining the physiological processes or mechanisms where such conditions develop and progress. It is a physiology of abnormal state that is normally followed by a disease or a syndrome.
