1. The forelimbs of the human, cat, whale, and bat contain homologous bones. The upper part has one bone, the lower part has two parallel bones, and the lowest part has a
number of small bones that can slide past one another. The butterfly wing contains no
bones.
A. Compare the structure and FUNCTION of the cat forelimb with the bat forelimb. Analyze
and evaluate the evidence for or against a common ancestor among these animals.
Indicate whether these are homologous or analogous structures.

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

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
