The insects in the order Odonata, including the dragonflies and damselflies, begin life as wingless aquatic nymphs and only later in life emerge as sexually mature, winged adults. If an evolutionary change produced a dragonfly that reached maturity while still in the aquatic stage, this would be an example of .

Pedomorphosis

Explanation:

Pedomorphosis is a type of evolutionary change that occurs when features or traits that are usually common with the juveniles or larval of an ancestral organisms, become displaced by the adult traits or features in the descendants of that organism. This can either be as a result of slowing down or the acceleration of the physiological development of the organism.

The dragon fly that is produced, which shows features of adult development at its aquatic stage, is an example of Pedomorphosis.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
