In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.

AveGali [126]

Answer:

During the method of photosynthesis, daylight is employed to convert water and dioxide into aldohexose and gas. light-weight reactions convert the energy in daylight into the energy of ATP and NADPH.

a) In the bright daylight, the Calvin cycle happens within the stroma. throughout the Calvin cycle, the products ATP and NADPH are accustomed convert molecules of carbonic acid gas into high-energy sugars.

b)In the darkness, the Calvin cycle conjointly happens within the stroma. throughout the Calvin cycle, the products ATP and NADPH are used to convert molecules of CO2 into high-energy sugars.

c) There will be a decrease in the products ATP and NADPH if the plants are unbroken within the dark for a protracted time and also the Calvin cycle can't be continued.

A bacterium that you isolated from pond water appears to use light for energy. Based upon this information, you inoculate the or
FinnZ [79.3K]

The question is incomplete as it does not have the options which are:

  • there was no sulfur compound added to the medium, that could be used as an electron donor.
  • no oxygen was added to the medium so the organism died.
  • there is some inhibitory chemical that is preventing the growth of the bacterium.
  • you were using the wrong type of sunlight as the energy source for the bacterium.

Answer:

There was no sulfur compound added to the medium, that could be used as an electron donor.

Explanation:

In the given question, the bacteria which are found in the pond uses light energy to use carbon dioxide and form the glucose molecule. These bacteria are known as phototrophic bacteria.

The process of photosynthesis requires an electron donor and an electron acceptor to use molecule.

The organism when provided the light and carbon dioxide artificially in a culture, the bacteria were not able to grow. The reason for this could be accounted as that there was no electron donor found in the media like sulfur which could donate the electron during the chain reaction.

Thus, the selected option is correct.
