Through secretory pathway or cytosolic protein through cytosolic pathway.
The cytosol consists mostly of water, dissolved ions, small molecules, and large water-soluble molecules (such as proteins). The majority of these non-protein molecules have a molecular mass of less than 300 Da. Membrane proteins are inserted into the endoplasmic reticulum (ER) by two highly conserved parallel pathways. The well-studied co-translational pathway uses signal recognition particle (SRP) and its receptor for targeting and the SEC61 translocation for membrane integration.
However, mRNAs that encode cytosolic proteins can also be translated by ER-bound ribosomes. Thus, a large fraction of the proteome can be translated by ER-associated ribosomes. Such a diverse and selective translation of mRNAs redefines this ubiquitous organelle as a primary site of proteome synthesis in the cell.

Answer:
Nitrogen is a constituent element and is part of many compounds in plants.
Explanation:
Nitrogen is a building block and there is no process in plants that is not affected by nitrogen.
If there is not enough nitrogen in the soil, the growth decreases, the leaves are yellow, pale green, chlorosis occurs, the root is removed, its branching is reduced, the yield and quality of fruits are reduced.
Answer:
Which of the following is true of the composition of all materials?
All materials are made up of smaller parts that cannot be seen without magnification
Explanation:
Material composition entails smaller parts that made up of such materials which are embedded in it. it could be chemical, addictive, which are not seen
C it will be c because earth has water
Answer:
C. At least five mass-extinction events have occurred during the last 500 million years.
Explanation:
- The history of mass extinct is related to the five mass extinctions that are caused over by the 350 million years n which many species have disappeared in there short geologic time.
- A massive extinction is caused in the Permian Triassic extinction event i.e about 250 mn years ago which on an estimate has killed 90% of the species.
- The Cretaceous–Paleogene extinction event that occurred over 66 million years ago is known to have wiped out the dinosaurs and many other species.
