Water at about 4°c (39°f) is more dense than water at 0°c (32°f). why would the living organisms in the lake die if the water at the freezing point was denser than the water at 4°c?

the water would freeze across the surface of the lake, blocking sunlight necessary for photosynthesis.
the water would freeze across the surface of the lake, blocking the dissolving of oxygen and nutrients.
the freezing water would sink before it could freeze, preventing the lake water from freezing.
the freezing water would sink to the bottom and freeze the lake water from the bottom up.

The answer is D

Explanation:

Just got it right. Trust me its not A.

it should be briana that has it 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
