ANSWER
Both flowing plants and animal pollinators are incredibly diverse. One reason for this diversity is the close
relationship they have with one another. Over many years, some flowers and pollinators have influenced each
other's evolution. Today, when flower-pollinator pairs have traits that work very well together, it's a sign
this kind of evolution may have happened.
Ring species.
When there are neighbouring populations that can interbreed with each other while only two of those populations cannot breed between them, we are standing before a ring species. In the case of Larus gulls what is observed is that several of these species can interbreed, but it comes to two of them that are incompatible - they are probably to<span> distantly related to interbreed. It is considered, that this species may be connected to each other in a line of derivation and is both ends on that line that are incompatible.</span>
Answer:
Hydrogen bond: It is a type of bond which exist between hydrogen atom and other atom having high value of electronegativity. Those atoms having high electronegativity values has the capability to attract the shared pair of electron towards itself. Hydrogen atom have very low value of electronegativity, so the shared pair of electron goes farther from it and nearer to high electronegative atom such as oxygen in water molecule. This bond is very weak than covalent bond.
It is not true bond due to weak force of attraction between atoms.
Rushing, fatigue, distractions and complacency are HUMAN FACTORS medical errors.
