Answer:
A
Explanation:
Before exchange, it is expected that the capillaries (that have deoxygenated blood) will have more carbon dioxide while the lungs will have more oxygen. This allows for oxygen to diffuse into the capillaries while carbon dioxide diffused into the lungs during the exchange.
Answer:
RER is involved in protein synthesis, folding, transport and modification.
Explanation:
The Endoplasmic Reticulum is an organnelle found in eukaryotic cells. They are of two types; Rough Endoplasmic Reticulum and Smooth Endoplasmic Reticulum, so named based on the appearance of their surface. The Rough Endoplasmic Reticulum (RER) obtains it rough appearance from the membrane bound ribosomes attached to it.
Due to the ribosomes that attach to them during protein synthesis, their function is very much associated with protein synthesis. They are primarily involved in protein production, which would either remain in their lumen for further modification/processing called Glycosylation (adding sugar to proteins to form glycoproteins) or be transported through secretory vesicles to the Golgi apparatus. They also fold this proteins in their inner membrane structure called cisternae.

Answer:
Primary Consumer Definition. A primary consumer is an organism that feeds on primary producers. ... Primary consumers are usually herbivores that feed on autotrophic plants, which produce their own food through photosynthesis.
