In a recent experiment, anti-bacterial hand sanitizer was compared to hand soap. students washed their hands using the sanitizer or soap and warm water for two minutes; then they dried their hands with a paper towel. the standard of comparison was rubbing hands vigorously for 2 minutes in warm water, without any soap or sanitizer, and then drying with a paper towel. the sanitizer advertisement claimed to kill bacteria more effectively than any soap. after washing, hands were swabbed and then the swab applied to a culture plate and incubated. finally, the bacterial cultures were counted and recorded in the data table. what would be a valid conclusion to draw from this data? a) all methods are effective in killing bacteria. b) both soap brands out perform hand sanitizer in killing bacteria. c) warm water is as effective as soap or sanitizer in killing bacteria. d) hand sanitizer is more effective than either soap in killing bacteria.

explanation:

carbon can form so many different compounds not just with oxygen

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.

looks like the answer is     c     to me!

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
