Alli and her classmates want to know which species of oak produces the acorns that squirrels prefer. which possible procedure is likely to produce the most reliable results?
work together to observe where one squirrel spends most of its time, and record which acorns it buries for one hour, repeating daily for two weeks.
dig up and identify each type of acorn buried under one tree at the end of each day for a three-week period.
divide up and observe squirrels in ten locations for two hours, then dig up and identify each type of acorn buried by squirrels, repeating daily for two weeks.
observe and record the number of squirrels that approach each species of tree in a specific location for one hour each day for two days.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

✿   this landform has a high elevation and a high relief

✿   this landform is a mountain

cuz he is really really short, assuming an unorthodox and inherently unlucky configuration of elevator buttons…
