Answer:
B)Prophase,Metaphase,Anaphase,Telephase
Explanation:
Prophase:At this stage,the chromatin threads condense to form distinct chromosomes, long and thin at first,later become shorter and fatter. Nucleolus disappears, nuclear membrane disintegrates, series of spindle (protein) fibres are formed spanning the cell from end to end.
Metaphase:Here, Chromosomes migrate to the central plain of the cells and arrange themselves round the equator of the spindle, attached by centromeres to be 'spindle fibres' microtubule.
Chromatids of each chromosome move slightly apart at the centromere regions,the sister chromatids being oriented towards opposite poles
Anaphase: Chromatids belonging to each chromosome part company and move towards opposite poles of the spindle, probably by a pull from the spindle fibres attached to the centromere which shortens.
Telephase: Chromatids reach the polar ends of the spindle and become densely packed together. Cell divide into two. Spindle fibres break down, centrioles replicate. Nuclear membrane is re-formed. Nucleolus reappears. Chromosomes gradually uncoil and return to their original thread-like form i.e, Chromatin threads.
B. An Experiment, Mainly because a hypothesis is a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation. A prediction is a <span>prophecy, And an observation is something that isn't full proven but opinioned. Therefore leaving B. An Experiment The only logical answer above. </span>
Answer:
Answer is 3. Hope this helps!
Explanation:
Answer:
D
Explanation:
it basically sums up A and B and seems the most likely
D is the answer because carbondioxide and oxygen are both needed for plants or green plants to survive.
I hope it helped
