Which of the following best describes the relationship between atmospheric
CO2 levels and global temperature
1. CO2 and global temperature have
fluctuated over the past 800,000 years,
with periods of high CO2 correlating with
higher global temperature
2. Both CO2 and global temperature have
stayed relatively stable over the past
800,000 years
3. There has been fluctuation in both CO2 and
global temperature over the past 800.000. 4. CO2 and global temperature has fluctuated over the past 800,000 years, with periods of high CO2 correlating with lower global temperature

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

i think its white blood cells

i hope this

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
