Answer:
c) Ribosomes on the rough endoplasmic reticulum; Golgi apparatus
Explanation:
Endoplasmic reticulum, a member of endomembrane system. If it contains ribosomes on their surface, they are called Rough Endoplasmic Reticulum (RER). RER is the site for protein synthesis.
Newly formed protein undergoes modification, one such modification is the addition of carbohydrate side chains to form glycoprotein. The protein then moves to the Golgi for modification.
Well C or A would work because both are polite so yeah
1. substrate
2. active site
3. reaction
The energy came from the sun.
The sun increase the temperature on every water surface on the earth which make it transform from liquid to gas, and eventually from cloud.
When the clound condensed, it will fall on top of the geological surface in the form of rain and some of it will fallen to the river and eventually came back to the sea to complete the cycle.
