Answer: Option B.
Polar covalent bonding.
Explanation:
Hydrogen bonding or polar covalent bonding exist between water molecules. Water have one oxygen molecules that is electronegative and two hydrogen molecules that is slightly electropositive. Two hydrogen atoms are covalently bonded to one oxygen atom. In covalent bonding, there is sharing of electrons between atoms. In water, there is unequal sharing of electron between oxygen atom and hydrogen atoms. Oxygen atom tend to attract more electrons that hydrogen atoms, which make water a polar molecule.
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:
Genus
Explanation:
In the scientific name "Panthera tigris", Panthera is the name of the genus and the "tigris" is the name of the species. Similarly in the name "Panthera leo", the name "Panthera" denotes the genus while "leo" is the species. This means that the tiger and lion belong to the same genus. They both belong to the genus "Panthera".
Though the species of the tiger is "tigris" and that of the lion is "leo". Both are the species of the same genus since the genus includes closely related species. The members of these different species can not interbreed but share some common features as they belong to the same genus.
Answer:
Hurricanes generate strong winds that can completely defoliate forest canopies and cause dramatic structural changes in wooded ecosystems. Animals can either be killed by hurricanes or impacted indirectly through changes in habitat and food availability caused by high winds, storm surge, and intense rainfall.
