Lake Victoria in East Africa is home to many species of fish called cichlids. In 1954, the predatory Nile perch was introduced to Lake Victoria. The Nile perch became the dominant fish species in the lake by the mid-1980s. The number of cichlid species in the lake decreased as the Nile perch population increased. The perch preyed heavily on cichlid species that fed on algae and debris on the bottom of the lake. Algae in the lake increased, the oxygen levels decreased. The surface area of the gills of some cichlid species has increased in just over 20 years. Increase in Gill Surface Area in Some Lake Victoria Cichlids

Which statement explains the increase in gill surface area seen in some of Lake Victoria's cichlids?

Increased gill surface area has allowed the cichlids to change their diet and avoid competing with the Nile perch.

Increased gill surface area allowed the cichlids to be camouflaged and avoid being eaten by the Nile perch.

Increased gill surface area has allowed the cichlids to leave Lake Victoria and establish populations in nearby bodies of water.

Increased gill surface area has allowed the cichlids to better absorb the limited oxygen in the water.

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
