You're conducting an experiment to determine the effect of different wavelengths of light on the absorption of carbon dioxide as an indicator of the rate of photosynthesis in aquatic ecosystems. If the rate of photosynthesis increases, the amount of carbon dioxide in the environment will decrease, and vice versa. Small aquatic plants are placed into three containers of water mixed with carbon dioxide. Container A is placed under normal sunlight, B under green light, and C under red light. The containers are observed for a 24-hour period. Carbon dioxide absorption is an appropriate indicator of photosynthesis because:.A) CO2 is needed to complete the light reactions.B) The energy in CO2 is used to produce ATP and NADPH.C) Plants produce oxygen gas by splitting CO2.D) CO2 is needed to produce sugars in the Calvin cycle.

The preferable option will be - D.

D. CO₂ is needed to produce sugars in the Calvin cycle.

Explanation:

We know that CO₂ is the prime element for photosynthesis. CO₂ is the only source that supplies carbons in this process. With the help of  CO₂, water, light, minerals, and chlorophyll, six-carbon glucose is formed. This glucose is converted to starch and is stored in fruits or in the parts of plants for further use.

Solution:

We do you include a start and stop dna sequence in the cut sequence because  mutation either exchanging a Purine with another Purine, Pyrimidin with another Pyrimidin, or completely exchanging a Purine with a Pyrimidin or vice versa. Point- or Frameshift-Mutation. To cut DNA into smaller segments, nucleases are used. They do thisby taking the phosphodiester bonds' hydrolysis and catalyzing it. A gene is a DNA molecule which determines an inheritable trait. There are also two types of genes. -Recesive (rare) -Dominant (common) An example would be.. Blue Eyes are considered recesive. Brown Eyes are dominant. (rare) (common)

Changes in a DNA sequence of a single gene is called a point mutation. These mutations can be harmful or not to the organism.

I. New DNA segments can be inserted. II. New DNA segments can be substituted. III. DNA segments can be deleted

This is the required answer.
