If thymidine dimers created by UV irradiation persist until DNA replication, DNA polymerase is likely to make a mistake reading
marishachu [46]

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.

Under which conditions do most types of cells function at optimal levels
Scrat [10]

Explanation:

Cells maintain a constant internal environment; this process called homeostasis, ensures that cells obtain an optimal environment in which they can best function.

The endocrine system involves chemical signalling via the secretion of molecules called hormones into extracellular fluid. They bind to chemical receptors in order to cause specific changes in target cells, these lead to changes in the body's internal environment called homeostasis.

It includes the thyroid, parathyroid, pituitary, pineal and adrenal glands along with other regions. The bone, adipose tissue, heart, pancreas and liver are a few of the regions of the body which show endocrine function. The brain, or control center functions to receive and process the information from the receptor. Effectors receive the control center's command and illicits a response in the form of a feedback loop, that may oppose or enhance the stimulus.

Further Explanation:

During homeostasis the body maintains a constant internal balance in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis. Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.

For example, cells within the human body function at an optimal temperature between 97°F (36.1°C)  and 99°F (37.2°C). This is due to the optimal temperature requirement of the enzymes within the human body, which requires this specific range to obtain activation energy.

Em 2015, os países e a população global se reuniram para decidirem sobre novos caminhos, melhorando a vida das pessoas em todos
aliya0001 [1]

Answer:

O principal objetivo da prática 12 é reduzir as perdas e usar os recursos naturais de maneira adequada.

Explanation:

Consumo sustentável significa que o uso dos recursos naturais é muito eficiente para evitar a poluição do meio ambiente. recicle o material usado e use-o novamente para reduzir o custo e também a poluição que ocorre durante sua fabricação. Use materiais que não agridam o meio ambiente e reduzam o uso de combustíveis fósseis. Reduzir perdas de alimentos e também evitar perdas que ocorrem após a colheita da colheita, a fim de fornecer mais alimentos para a população existente. O resultado esperado com a prática número 12 para um consumo mais sustentável pela população global é que mais alimentos e recursos estejam disponíveis para a população existente. população.
