You examine a population of dividing cells with an electron microscope, and you see a large, floppy, circular string near the ce

nter of the cell that seems to be tangled with another floppy circular string. Deducing that the strings are the replicating DNA of the cell, you determine that the cell is a prokaryote and is undergoing _______.

Answer:

Binary fission

Explanation:

Prokaryotic cells do not have a nucleus. Binary fission is one of the methods of asexual reproduction in them. During the process, replication of circular DNA begins at the origin of replication and continues as the replication is bidirectional and the enzymes synthesize DNA in both directions.

As the replication comes to an end, the cell appear to have two circular DNA molecules entangled with each other. The septum grows towards the inner side as the chromosomes move toward opposite ends of the cell. This is followed by the formation of septum completely through the cell center, to make two separate cell chambers.

galben [10]

DNA in prokaryotes frees in the cytoplasm, while in eukaryotes (like humans) DNA is in the nucleus.

Human DNA is found in the cells that make up your tissues and organs: nerve cells, liver cells (liver), skin cells ... They are extremely numerous, more than 50 000 billion and have very diversified functions! Most of our cells are microscopic (20 to 30 micrometers) and contain an even smaller nucleus structure.

Each nucleus contains the genetic material of the cell, the chromosomes.

Mitochondrial DNA can also be found in mitochondria, but mitochondria are much smaller than nuclear DNA.

all plants give out oxygen during day and carbon dioxide during night. Do you agree with this statement. Give reason
Citrus2011 [14]

This statement is incomplete.

"All plants give out oxygen during day and carbon dioxide during night"

Explanation :

Photosynthesis occurs only during day time.

During this time oxygen is produced . Some oxygen is used for respiration and rest of oxygen is diffused out into air.

Carbon dioxide produced during day time by respiration is used in photosynthesis.

But at night time, no photosynthesis occurs  and hence no oxygen is produced oxygen from air diffuses into leaves to carry out respiration and carbon dioxide produced by respiration diffuses out into air.

Hence Respiration occurs day and night .. Hence Carbon dioxide  is emitted  all the time....

The description of a cell's energy process is listed below.
PSYCHO15rus [73]

Answer:

The correct answer is c aerobic respiration

Explanation:

The process glycolysis,TCA cycle and electron transport chain are additionally called Aerobic respiration.

              Glycolysis occurs in the cytoplasm and deals with the catabolism or break down of glucose in a sequence of enzyme catalyzed steps to form pyruvate and ATP.

          TCA cycle occurs in Mitocondria.This metabolic process helps in the formataion of ATP along with the  oxidation of glucose to generate CO2 and H2O.
