3. According to your toxicity pyramid which of the organisms is going to be affected the most by the pesticide? Explain why. 4. If this organism dies (from question 3), what might the secondary effects be on Uncle Bob’s garden? 5. When the pesticide was passed from the roses to the aphids to the dragonfly or restless fly catcher, was it moving up the food chain or down the food chain? 6. What happened to the insecticide concentration as it went from roses to restless fly catcher? Would this happen all the time or only sometimes? 7. What would happen if you the restless fly catcher ate more than one dragonfly? 8. Do you think that all birds that eat from the same garden have the same insecticide concentration? Why or why not? 9. Write a letter (on the next page) to Uncle Bob explaining the dangers of using pesticide X in his garden. Make sure to explain "biological magnification" to get your point across.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.

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

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
