Answer:
The below options will complete the question
Select one:
a. Gap repair synthesis
b. Mismatch repair
c. Direct repair
d. Nucleotide excision repair
Our answer is surely A.
a. Gap repair synthesis
Explanation:
Alleles of gene B differ by 6 bps and are seeming close to each other among the 1123 bp within the particular gene, favouring the gap repair synthesis.
In the gap repair synthesis, a double stranded break is formed at a homologous chromosome with a small part of the gene or the 6 bps of the recessive allele
being digested away.
Strand invasion and a D-loop formation is followed by the new region being occupied by the dominant B allele to yielding dominant B allele in both chromosomes.
The gap repair synthesis allows the 6bps to be converted to the dominant B from the recessive b when in proximity/being close together.
Answer:
D. A hurricane carries ocean water across the coast and damages houses of people.
Explanation:
This question is looking for a statement that shows the interaction of an atmosphere, hydrosphere and biosphere. Firstly, atmosphere refers to the layer of the air that surrounds the earth i.e it pertains to air. Hydrosphere refers to the part of the earth occupied by water bodies e.g sea, river, ocean etc. i.e. it pertains to water.
Biosphere is the part of the earth that has to do with life i.e. it pertains to living organisms e.g plant, animal, human etc.
Based on the definition of each component, option D truly shows the relationship/interaction of the three components mentioned. That is, A hurricane (represent part of the atmosphere because it has to do with air) carries ocean water (represents hydrosphere because it involves water body) across the coast and damages houses of people (represents biosphere because it talks about living humans).
Answer:
Catalytic hydrogenation is treatment with hydrogen in the presence of a catalyst such as nickel, palladium or platinum. Catalysts are required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures. Hydrogenation reduces double and triple bonds in hydrocarbons.
