Answer:
That is administered and controlled
Step-by-step explanation:
A variable is the condition or a product that may vary without the influence of any investigator. Such variables can be found abundantly in our daily lives, ranging from air to sunlight. Controlling such variables ensures the limitation of their influence on the outcome of an experiment. In connection to this experiment, the variables that are controlled are the mineral content in the water, the amount of bacteria food, the amount of light and the the constant temperature of 20 degrees C.
If not administered or these variables controlled, the experiment would not clearly explain the impact of caffeine on the heart beat of the water fleas as other variables may have influenced it. Thus variables are controlled to study the singular impact of any agent or effect.
<u>In the process of translation, the statement stands correct and applies are as follows:</u>
- The ribosome has two sub-units that work together.
- Amino acids are joined by peptide bonds.
- Each tRNA brings in exactly one amino acid that corresponds to the anti-codon.
- The order of the amino acids is determined by the mRNA which is transcribed from DNA.
Answer: Options A, B, C, and E
<u>Explanation:</u>
In the process of translation, ribosomes are the structural unit where the translation is being performed and it has the two sub-units which enact together the translational process.
Any two amino acids are bonded together by peptide bond and tRNA brings one amino acid at a time which corresponds to the anti codon. The order of amino acids is determined by mRNA transcribed from the DNA, and not from the ribosome. Thereby, all given options are correct except the option D.
4. nucleoid region
Bacterial cell's do not have a nucleus; their DNA is found in this region.
It should be a short-day plant because it grows in the winter.
