<span>This happens because the proteins for the ER (proteins for secretion) are translocated into the ER during their synthesis (translation) on membrane-bound ribosomes and this is called cotranslational translocation. Proteins that are destined for the ER are marked with the signal sequence (signal peptide) at the amino terminus of the growing polypeptide chain. The signal is a series of hydrophobic amino acids, usually found near the N-terminus of the protein. and it’s recognized by a protein complex called signal-recognition particle (SRP), which takes the ribosome to the ER.</span>
Producers, because they start the chain and the top most level finishes it.
Depends on what mountain you are on
If you are on Everest, then the amount of effective oxygen available would be 6.9% (0 altitude would be 20.9)
that is why anyone should always bring oxygen tanks when climbing a high mountain
Explanation:
Each part of your digestive system helps to move food and liquid through your GI track, break food and liquid into smaller parts, or both. Once foods are broken into small enough parts, your body can absorb and move the nutrients to where they are needed. Your large intestine absorbs water, and the waste products of digestion become stool.
