Answer:
According to the diagram shown, the section of DNA used to make the mRNA strand is known as a gene (option 2).
Explanation:
Gene consists of a DNA fragment that codes for the synthesis of a specific protein that defines the structural or functional trait of a living being.
When DNA is transcribed into mRNA, each section of transcribed DNA is part of a gene. The information travels to ribosomes in the cytoplasm where protein synthesis occurs.
A complete DNA molecule forms a chromosome, which contains the genes with information to define specific traits of a species.
The other options are not correct because:
<em> 1.Carbohydrate is a biomolecule that is not involved in the genetic process.
</em>
<em> 3. Ribosome is where protein synthesis occurs.
</em>
<em> 4. Chromosome is the complete DNA molecule.</em>
Greenhouse gases arise naturally, and are part of the make-up of our atmosphere. Earths conditions are just right to allow life, including us, to flourish. Part of what makes Earth so amenable is the naturally-arising greenhouse effect, which keeps the planet at a friendly 15 °C (59 °F) on average. But in the last century or so, humans have been interfering with the energy balance of the planet, mainly through the burning of fossil fuels that give off additional carbon dioxide into the air. The level of carbon dioxide in Earth’s atmosphere has been rising consistently for decades and traps extra heat near the surface of the Earth, causing temperatures to rise.
The correct option is C.
Scanning electron microscope is a type of microscope that uses beams of electrons that are reflected to form images to scan the surfaces of mounted biological specimens. High resolution, three dimensional images can be obtained via the reflected beam of electrons. Thus, the electron scanning microscope is the perfect microscope for examining the contours on the surface of a bacterial cell.
