Answer:
Xylem and phloem
Explanation:
Xylem and phloem are the conducting tissues of the vascular strands. Their main role is in the transportation of food, minerals, and water. Xylem is the tissue which is responsible for the transport of water in plants while the phloem is responsible for the transfer of food and nutrients in the plant.
I think the answer would be B but none of them are great. Continental drift is the gradual movement of our land masses. Knowing this we can eliminate option D because it identifies buildings as a cause. A and C both discuss climate change which is not a product of continents moving. The elimination leaves option B however because these changes would occur gradually, it is unlikely that species would become invasive.

Answer:
d. smooth endoplasmic reticulum
Explanation:
Organelles are structures found in inside the cell which carries out a specific function. Types of organelles include endoplasmic reticulum, Golgi body, ribosomes, nucleus etc. The function in the question is protein synthesis.
Ribosomes are the sites of protein synthesis in the cell of living organisms.
- The nucleus is involved in the synthesis of protein because it directs all the cellular processes in a cell including protein synthesis.
- Rough endoplasmic reticulum (RER) is a type of endoplasmic reticulum whose surface is attached to by ribosomes, hence, giving it its rough surface. Since ribosomes (organelle for protein synthesis) are attached to the RER, the RER are involved in protein synthesis.
- Golgi bodies are organelles that functions to package, process and sorted the proteins produced in the ribosomes.
- The smooth endoplasmic reticulum (SER) are NOT involved in the synthesis of protein because they have no ribosomes attached to their surface. Instead, they are involved in lipid synthesis.
