If you need to clarify the directions for a lab activity, what should you do?
a. contact your instructor.
b. find a new way to do the lab.
c. perform an internet search for .
d. skip over the steps you don't understand

Option A, Contact your instructor.

Explanation:

A lab instructor has in depth knowledge and understanding of all lab activities. He/she has years of experience in guiding students regarding the successful conduction of lab activities.

In case if any student has any doubt regarding any lab activity, he/she must consult with the lab instructor only. Also, all lab activities require avoiding some common mistakes which are done by most of the students when they do the test/experiment for the first time. An instructor is aware of these common mistakes and thus he/she can guide better than all

Thus, option A is correct.

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
