D. photosynthetic decomposers
Answer:
Protein Synthesis
Explanation:
DNA transcribes information into the RNA of the nucleus. Transcription is making copies of information from DNA and applying that information into a new format. The RNA first stays in the nucleus and then travels to the ribosome on the rough endoplasmic reticulum through the cytoplasm. Here the translation of RNA done. The information the DNA which was copied onto the RNA during transcription is translated into a sequence of amino acids in this stage. In the next step, the amino acid chains, or polypeptides, are constructed in the correct sequence to form proteins.
After synthesis of protein, a part of the rough endoplasmic reticulum takes off and separates to form a protein-filled vesicle. Then this vesicle travel to the Golgi complex where the protein is modified if needed and then repackaged into a new vesicle. The vesicles then carry out the protein to another organelle where it will be used within the cell or to the plasma membrane for secretion purposes.
Answer:
6,500 mL
Explanation:
We are asked to find the total volume of air that effectively entered to the alveoli in one minute so that oxygen could be exchanged for carbon dioxide and leave the body through exhalation.
The problem says that the normal breathing rate is 10 breaths per minute, and for each breathe it takes 800 mL of air. But not all air enters the alveoli because it says there are 150 mL that are not effectively used by the alveoli. Therefore, the net amount of air used in each breathe is 800 ml - 150mL, giving us a total amount of 650 mL of air.
Now that we have the net amount of air for each breathe, we have to multiply it by the total breaths a body makes in one minute. In this case, the breathing rate is 10 breaths/min.
So, to obtain the final answer we just need to multiply the amount of net air per breathe (650 mL) times the number of breathes in one minute (10 breathes); that is 650 mL/breath x 10 breaths and gives us 6,500 mL.
