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:
D. Animals burrow tunnels into the ground
Explanation:
In this scenario we have interaction between the biosphere and the geosphere. The biosphere is represented by all of the living organisms on the planet Earth. The geosphere is represented by all of the crust on the planet Earth. The animals are living organisms, thus they are part of the biosphere, and by doing an activity in the ground, in this case burrowing tunnels, they interact with the geosphere, so we have an interaction between the biosphere and the geosphere.
The answer to this should be C.
Answer:
C Intergovernmental Panel on Climate Change
Explanation:
The Intergovernmental Panel on Climate Change (IPCC) is an intergovernmental body of the United Nations that is dedicated to providing the world with objective, scientific information relevant to understanding the scientific basis of the risk of human-induced climate change
