Which water depth had the biggest difference in survival rates for embryos with uv-b protection versus embryos without uv-b protection? (a) 0 cm(b) 100 cm(c) 50 cm(d) 10 cm

10 cm

Explanation:

The water at 10 cm has the biggest survival rate for the embryos with ultraviolet B protection as compared to that of embryo which are not protected by UV-B.

Ultraviolet rays can be very harmful as it can reach the fetus but due to some particles present in water the intensity of UV-B becomes attenuated below 10 cm of water.

So, the correct answer is 10 cm.

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
