Explanation:
First during protein synthesis, transcription occurs in the nucleus, followed by translation within ribosomes. Then, newly synthesized proteins enter endoplasmic reticulum where they undergo folding and modification. Next, within the golgi body, the proteins are tagged; after,they are finally parceled into lysosomes. Finally, they can be exported out of the cell to fulfill various functions.
Further Explanation:
The endoplasmic reticulum is a membrane system within the cytoplasm that extends from the outer nuclear membrane. Apart from increasing the surface area within the cell, this continuous system also carries out protein folding, synthesis and transport. In the endoplasmic reticulum or ER, some sections called the smooth ER, do not contain ribosomes, and may contain lipids, enzymes, and other proteins. Other sections bound to ribosomes, are called the rough Er. As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen. The proteins undergo major modifications and are packed into vesicles.
Golgi bodies are flat, disk-like membranous regions. Proteins traverse the organelle by first having their vesicles bind to the cis face or receiving end. Like a post office, the golgi complex, or golgi body recognizes specific signal sequences, targets and further modifies and packages these compounds into lysosomes for delivery to their final destination. Proteins here undergo peptide processing and glycosylation

Answer:
Image result for What are the pathways of the carbon cycle?
The organic pathway of the carbon cycle moves carbon from the atmosphere, through producers and other organisms in ecosystems, and back to the atmosphere. The geological pathway moves carbon from the atmosphere, through the ocean to rocks and the mantle, and back to the atmosphere

Answer:
C) They are part of a community
Explanation:
A community represents the sum total of populations of different species present together in an area or ecosystem. In a community, the organisms of these different species may benefit or harm each other and exhibit little or more interdependence. In the given example, beer, insects, ants, chipmunks represent the organisms of different species that are present together in a habitat. They interact with each other in various ways. For instance, the bear is a predator of insects.
Answer:
