Answer:
B. They have a single small nucleus.
Explanation:
The presence of large nucleus is a characteristic feature of cells that frequently undergo cell division. Cancer cells are characterized by uncontrolled continuous cell division even when the new cells are not required by the body.
This leads to the formation of benign or metastatic tumors. To undergo continuous cell division, the cancer cells have a large nucleus. The nucleus of the cancer cells is mostly hyperchromatic and distinct due to higher nuclear to cytoplasmic ratio. It allows these cells to exhibit the uncontrolled cell division.
Answer: A would be the correct answer. Making observations would include scientists exploring the world around them
Explanation:
If the side of the triangle is ' S ', then . . .
-- Base of the triangle = S
-- Height of the triangle = 1/2 S √3
-- Area = 1/2 (base) (height) = (S² √3) / 4
-- Perimeter = 3 S
Area / Perimeter (numerical) = [ (S² √3) / 4 ] / 3 S
That ugly thing becomes <em>S √3 / 12 </em> .
Seismicity along divergent plate boundaries is concentrated along rocky areas away from the rift zones.
An oceanic ridge marks divergent plate boundaries in the ocean basins. It is broad, fractured swell with a total length of 70,000 km. Basaltic volcanism and shallow earth quakes are concentrated along the rift zone at the ridge crest. The ridge's characteristics depend upon the spreading rate.
