Question 6 of 10 Human volunteers who were coughing and sneezing participated in a clinical
study of a new drug. The volunteers were randomly divided into three groups
and treated as follows:
Group
Experimental
Group
Control
Group #1
Control
Group #2
New drug
Yes
NO
NO
Orange juice
Yes
Yes
No
Bed rest
Nyes
Yos
Yes
What was the purpose of control group #2?
O A. To determine if bed rest is the best way to get well
OB. To eliminate orange juice as a possible cause for the new drug's
effects
O C. To determine if the new drug was a possible method for getting
well
D. To eliminate bed rest as a possible cause for the new drug's
effects

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

it's false. hope i .
