Answer:
All of these environmental disturbances use such energy present within the ecosystem to survive and reproduce. In order to conserve the health of the environment, the best thing that can be done is finding ways to reuse the energy as much as we can such as recycling cardboards or tin cans. Other ways would be to lower use of carbon emitting cars and have more conservation awareness.
Answer:
They pick up oxygen from the lungs and drop off oxygen to the cells through the capillaries
Answer:
Just took this - it is: by observing cellular respiration under the absence of light.
Explanation:
Answer:
The correct answer is "proteins in which isoleucine is inserted at some positions normally occupied by leucine".
Explanation:
The missing options of this question are:
A. proteins in which leucine is inserted at some positions normally occupied by isoleucine.
B. proteins in which isoleucine is inserted at some positions normally occupied by leucine.
C. no abnormal proteins, because the ribosomal translation machinery will recognize the inappropriately activated tRNAs and exclude them from the translation process.
D. no proteins, because the inappropriately activated tRNAs will block translation
The correct answer is option B. "proteins in which isoleucine is inserted at some positions normally occupied by leucine".
In normal conditions, the enzyme leucyl-tRNA synthetase attaches one leucine amino acid to leucyl-tRNA as part of synthesis of proteins that have one or more leucine residues in their sequences. Since the enzyme of this mutant strain of bacteria mistakenly attaches isoleucine to leucyl-tRNA 10% of the time, approximately 10% of all the proteins that normally have leucine residues will going to have isoleucine. Therefore, These bacteria will synthesize proteins in which isoleucine is inserted at some positions normally occupied by leucine.
