Rachel Carson was one of the first ecologists to warn against the widespread use of pesticides and other potential mutagens and toxins. How might the presence
of a chemical mutagen in the environment affect the genetic makeup and size of
a population over time?

Explanation:

chel Carson was born just over 100 years ago in 1907. ... 1. Silent Spring was directed against the chemical industry and its production of deadly pesticides. ... “the elimination of the use of persistent toxic pesticides should be the goal”—as ... chemicals has shifted from cancer and the potential for genetic

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

c is the correct answer!
