Answer:

B. introns; exons

Explanation:

Related genes from different organism usually translate to proteins of indispensable functions. This means that the proteins must be similar in terms of amino acids produced. Therefore the coding region must be highly conserved. These can be found in the introns. Conversely, exons are not a part of the coding sequence and therefore not required for translation. These sequences may be less conserved.

Answer:

1.2The main processes involved in the movement of water between the different reservoirs are evaporation, condensation, transport, precipitation, runoff (water runoff from the ground surface), infiltration and transpiration

3.The large surface of the oceans (about 70 percent of the earth's surface is covered by oceans) favors the occurrence of large-scale evaporation. On a global scale, the same amount of water that is evaporated returns to Earth as precipitation. This however varies geographically

4.Earth from Space Although the engine of the cycle is the solar energy that originates the evaporation of liquid water, and therefore its passage into the atmosphere, the role of gravity is also fundamental, thanks to which precipitation falls and continental waters return to the oceans

5.The water cycle is powered by solar energy. The sun heats the surface of the ocean and other surface waters, which evaporates liquid water and sublimates ice, converting it directly from a solid to a gas. These sun-driven processes move water into the atmosphere in the form of water vapor

Hox genes: control which amino acids get plugged into polypeptide chains. control the development of language in humans. appear
o-na [289]

<u>Answer</u>: Appear to function in similar ways across diverse groups of organisms.

<u>Explanation</u>:

  • The <em>hox</em> genes are a subset of homeotic genes.
  • The function of the hox genes is to control the development of the body plan of an individual during the embryonic stage.
  • Thus, the basic body form of an organism is laid down with the help of these genes.
  • <em>These genes are present in many different species from fruit fly to mice to humans</em>.
  • The reason that they are present in different organisms is that there was a common ancestor that possessed the hox gene cluster and then the genes were passed on to different vertebrates. However, the slight changes that have occurred in these genes are due to duplication events.

Charra [1.4K]

Answer:

The correct answer for the given question is (D) radioactive DNA is found inside the infected cell and radioactive protein was found in the medium outside the cell. This demonstrates that DNA carries virus genetic information.

Explanation:

Harshey and chase conducted an experiment on bacteriophage in 1951 the bacteriophages that are used are responsible for infecting bacteria. they found that genes are not made up of protein but DNA.

This is an experiment that used the method known as isotope labeling. They tag DNA with Phosphorus and protein with sulfur as the coat of bacteriophages are also made up of protein. They found out the DNA of bacteriophages is inserted into bacteria while the protein coat remains outside in the medium. It means that only DNA is what transfer not the protein.
