The phase of cell division in which chromatin condenses into chromosomes is ____ A. anaphase B. metaphase C. prophase D. telopha
Lady_Fox [76]

Answer:

C (Prophase)

Explanation:

All cells undergo division in order to produce more daughter cells. Cell division occurs immediately after the interphase, which is a resting and preparatory phase for mitosis or cell division. Prior to cell division, the DNA is found to be coiled around histone proteins to form a structure called CHROMATIN. The process of cell division occurs in four phases; Prophase, Metaphase, Anaphase, and Telophase.

In the Prophase stage, which is the first stage of mitosis, this Chromatin begins to condense or becomes compact by undergoing further coiling into a visible X-shaped structure called CHROMOSOME. This shape of the chromosome is as a result of the replication into sister chromatids that occurred in the S-phase of interphase.

What accounts for the movement of water up the veins of a tall tree?
stiv31 [10]
First of all, the cohesive and adhesive properties of the water molecules fascilitate this. Water molecules stick together and with the walls of the vessels, creating a column of water which doesn t break easily. Moreover the xylem vessels of the tree are very narrow increasing the pressure. Finally, transpiration is taking place as water from the leaves evaporate, thus a continuous osmotic gradient is being created, causing water to be drawn up the tree

Prokaryotic DNA is enclosed within a nucleus, while eukaryotic DNA is not.<br>O True<br>O False​
blagie [28]

Answer:

False

Explanation:

Prokaryotes do not have a nucleus.

This means their DNA is not enclosed in a nucleus and instead is in the cytoplasm.

On the other hand, eukaryotes have nuclei, so their DNA is enclosed within a nucleus.

So, this statement is false.
