Answer:
B) a signal-recognition particle that brings ribosomes to a receptor protein in the ER membrane.
Explanation:
Each synthesized protein has to be targeted to the specific location and transported to that location. There are two possible ways for that transport: post-translational transport or co-translational transport.
• Co-translational transport occurs during the process of translation, and proteins transported this way are proteins bound for organelles in the endomembrane system (such as the ER, Golgi apparatus, and lysosome), plasma membrane proteins or proteins for the exterior of the cell. They have an amino sequence called a signal peptide which sends them to ER first.
• Proteins that do not have a signal peptide stay in the cytosol so, their transport is after the translation (post-translational).
Answer:
D. as an arrangement of four chemical bases
Explanation:
Our DNA is made up of 4 chemical bases (adenine, thymine, guanine, cytosine).
Answer:
I think B
Explanation:
Because it is not a physical weathering example, it is not based on the weather it is based on a growing plant.
Choice "C" In an Endothermic Reaction, a reactant is taking energy (in this case sunlight).
I hope this helped you!

Describe how phloem is affected if the leaves start to die off. (3 points) The phloem is effected by the deprivation of water from the disease of the tree, as a result the metabolism of the plant will shift down ward causing the phloem to decrease due to the dying of the leaves.
