Explain how clearing forest by cutting and burning trees contributes to climate change

Answers

By cutting down trees you are reducing the number of CO2 that is consumed by trees. Trees consume CO2 to conduct photosynthesis and turn it into O2 which is released. kept a result of the CO2, more heat is contained within the atmosphere because CO2 is a heavier gas and heat has a harder time escaping from it. Hope this helps! :-)
If they cut all of the trees down and burn them. The climate will change by animals dieing because they dont have anny food water or a home to live in so they will die out or migrate somewere else.

Which type of RNA carries the genetic information from DNA to the site of protein synthesis?

Answers


The type of RNA that carries genetic information to the site of protein synthesis is messenger RNA or mRNA in short.

The first step for this to occur takes place in the nucleus of the cell in a process called transcription. In this process, the genetic information for the synthesis of a particular protein is copied onto mRNA, in a triplet base format and it is in code,

mRNA then leaves the nucleus and enters into the cytoplasm of the cell where it attaches itself to a ribosome. A ribosome is the site where proteins are synthesized and is also nicknamed the "work bench" of the cell.

Another type of RNA called tRNA then reads the coded information on the attached mRNA and recognizes a triplet of bases on it and decodes the information. This process is called translation. tRNA then fetches the amino acid that corresponds to that triplet of bases from the cytoplasm and into the ribosome where the amino acid is linked to others to form a chain and  thus a protein.

Which of the following is a mode of reproduction that is incapable of producing clones? A). budding in hydra B). fragmentation in algae C). runners in strawberry plants D). cross-pollination in corn plants

Answers

I think the correct answer from the choices listed above is option D. Cross-pollination in corn plants is the mode of reproduction that is incapable of producing clones. With this reproduction, the result varies widely and the resulting plant is not the same variety of the parent plant.
