A student conducts an experiment to see how music affects plant growth. The student obtains four identical plants. Each one is p

otted in the same type of soil and receives the same amount of sunlight and water each day. Plant A listens to classical music for three hours each day. Plant B listens to rock music for three hours each day. Plant C listens to country music for three hours each day. Plant D does not listen to any music at all.
13. Based on the experiment in the scenario, which visual aid would be most helpful in showing the change in the plants' heights over time?

Answer:

Plant A listens to classical music for three hours each day

Explanation:

  • Music affect plant growth of plants through the vibrations that it creates to the sound waves.Classical music causes more pressure to the sound waves causing vigorous vibrations  which is picked up by the plants speeding up the protoplasmic movement in the cells.
  • The vibrations causes movement of  the plant cells which speed up growth of the plants by stimulating the plants to produce more nutrients enabling them to germinate having more leaves,greater in size and other improved characteristics which means the plant's genetic chromosomes were changed.  
  • Also in the soil  is able to produce good fungi and bacteria encouraging better root development due to healthy vines resulting to vigorous growth and better fruit.
  • Moreover the plants are able to receive special attention and care from the farmer thus enhancing faster growth.

Answer:

The correct answer is the kind of music each plant listens to.

Explanation:

A variable refers to any condition or element whose value gets modifies in an experiment. A variable can take place in distinct quantities or types, and three kinds of variable, that is, dependent, independent, and controlled can be witnessed in an experiment. In the experiment mentioned, the kind of music each plant is listening to is the variable.  

It is an independent variable whose value is modifying as it prevails in distinct kinds and it is the one that the student is using to witness its effect on the growth of the plant. In the experiment, this variable that differs also generate distinct effects or outcomes.

How might you alter a trna so that it inserts an alanine into a polypeptide for which a lysine is coded?
castortr0y [4]
TRNA stands for transfer-RNA which is used in the process of protein synthesis or translation. tRNA is a unique clover leaf like structure that has 4 arms- amino acid acceptor site (acceptor arm), D loop, T psi C loop and anticodon loop. It also has a small variable loop. The anticodon loop consists of a sequence of 3 bases that is complementary to the 3 bases present of mRNA to be translated. A tRNA for alanine will have an anticodon for alanine while a tRNA for lysine will have an anticodon for lysine. For a tRNA to insert an alanine in place of lysine in a forming peptide, the anticodon and the amino acid acceptor site should be altered so that it accepts lysine in place of alanine and add it to the growing polypeptide.
