Measurements of the amount of dna per nucleus were taken on a large number of cells from a growing fungus. the measured dna levels ranged from 3 to 6 picograms per nucleus. one nucleus had 5 picograms of dna. what stage of the cell cycle was this nucleus in

G2

Explanation:

The nucleus shown in the question above is at the G2 stage of the cell cycle.

The G2 phase occurs during the end of the S phase and the beginning of mitosis. During this phase, protein synthesis initiated in the G1 phase continues, there is also the duplication of centrioles and all cytoplasmic organelles. The cell increases in size and volume indicating that the dividing process is about to happen. In addition, at that moment it is possible to visualize that the measured levels of DNA varied from 3 to 6 picograms per nucleus.

i'd say that the moon rock is about 2.2 billion years old.

i think a) betsy can donate only blood to mark is correct because, mark and betsy have the same blood type. whereas nobody else has b+ blood so betsy can't donate to them.
