The doppler effect changes the wavelength of the light emitted, depending upon whether source is moving away or coming towards the detector.
DNA sequencing suggests that among the green algae, the Stonewort are most closely related to land plants.
<h3>
What is DNA Sequencing ?</h3>
DNA Sequencing is a technique to determine the bases, nucleic acid sequence in the DNA. It is important to know the functions of genes, coding and non-coding part of proteins, identify the diseases, effectiveness of drug delivery etc.
<h3>
What is Land plants and Stonewort ?</h3>
Stonewort is commonly known as Chara . It is a freshwater green algae which comes from the Charophyta division. Fossils of Charophytes shows that Stonewort is a type of algae which is 470 million years old.
Thus from the above conclusion we can say that DNA sequencing suggests that among the green algae, the Stonewort are most closely related to land plants.

Answer:
Plate has all the essential nutrients that is required by the bacteria.
Explanation:
Bacteria grows on the plate, which indicates that the plate has all the essential nutrients that is required by the bacteria. Bacteria needs a type of media for its growth which contains all the necessary items which plays a key role in its growth and development. This plate has a media that contains food which the bacteria use for its growth and development so that's why we can say that plate has all the essential nutrients that is required by the bacteria.
Answer:
The correct answer is - temperature, pH, substrate concentration.
Explanation:
Various factors affect the rate of enzymatic reaction such as pH, temperature, substrate concentration, availability of activators or inhibitors in the reactions, and enzyme concentration.
Temperature: Temperature affects the rate of the enzyme-catalyzed reactions. Like most of the reactions with an increase in temperature rate of enzymatic reaction also rises up to a maximum level and then declines if the temperature continues to increase as enzyme denatures after a particular temperature.
pH: Similar to the temperature pH also increases the rate of reaction up to a maximum level and then declines the rate as every enzyme acts only at an optimum pH range.
Substrate concentration: If the substrate concentration is increased gradually while the concentration enzyme remains constant, the rate of reaction will increase until it reaches a maximum.
