Many flowering plants coevolve with specific pollinators. The Madagascar orchid has a 12-inch floral tube and is a reliable nectar source for the Hawk moth, which has a correspondingly long proboscis (tongue). Which statement most accurately describes how coevolution might have occurred for the Hawk moth and Madagascar orchid shown here?

Natural selection would favor orchids with nectar tubes just long enough to for an insect with pollen to make contact. Hawkmoths whose tongue could reach the deep tubes wouldn't be more fit.

Explanation:

Natural selection is a process whereby the better fitted or adaptive varieties of species in populations are selected by environmental pressure. This is a never ending process in nature since some environmental factors keeps on changing all the time.

Just like the the above example, the different proboscis parts are modified for different ways of feeding for both organisms which favours orchids which has nectar tubes which a just long enough for an insect with a pollen to make contact while at the other end, Hawkmoths whose tongues could not reach would not be more fit and at this cause or rate, could easily fade away or evolve.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
