Considering the following;
I. Heat is not readily available to all living cells.
II. Heat at excessive amounts denatures proteins.
III. Heat does not provide the activation energy for their reactions.
IV. When a critical temperature is reached, proteins no longer function
Answer;
I and IV
Explanation;
Living cells cannot use heat to provide the activation energy for biochemical reactions because heat is not readily available to all living cells and also when a critical temperature is reached, proteins no longer function.
Too much heat can kill an organism by rendering its organelles, cells, tissues and organs permanently inoperable and un-salvageable. The same process can be observed in tissues at low temperatures, and is the cause of frostbite. This is because enzymes are denatured by high temperature and inactivated by low.
Ammonia is well known as a weak base it can also be known as a extremely weak acid
In this case, the plot 1 is very rich in the single species; it is dominated by a particular species, which occupy 95% share. While in the plot 2 are rich in the number of species, it has 5 species occupying 20% share.
In comparative analysis, it is seen the plot 1 is rich in species, but diversity is very less. While, plot 2 is rich in the diversity of species, as 5 different species are present, but it is not rich in a particular species.
Hence, compared with plot 1, plot 2 has greater species diversity and lower species richness.
It would take 31 codons to code for a protein that contains 30 AA
Answer:
The advantage and disadvantage of UV exposure is listed below
Explanation:
Advantage
Ultraviolet radiation is used as sterilizing agent before culturing a bacteria of fungi in an autoclave.
Disadvantage
Ultraviolet radiation exposure can cause DNA damage by the formation of cyclobutane ring between two adjacent thymine residues known as thymidine dimers along a DNA strand.
Ultraviotel exposure can cause skin cancer.
