Answer::-
B. Water and nutrients absorbed by roots to the stem and leaves.
Xylem constitutes of the complex tissues and plays the role of conducting tissue for water and minerals from root to the stem and leaves (shoot).
Our most distant predecessor is Australopithecine who lived about up to 3 million years ago. Then homo habilis and homo erectus evolved, but they have been living more less at the sime time - it's unsure which of them was the first one (it was about 2.5 million years ago). Homo sapiens appeared about 200 thosuand years ago.
Answer:
The membrane protein would remain in Golgi complex and would not be targeted to plasma membrane.
Explanation:
Proteins are synthesized at the surface of the rough endoplasmic reticulum. Endoplasmic reticulum and Golgi complex coordinate for protein targeting. Proteins formed on the rough ER are packed in transport vesicles that bud off from the surface of rough endoplasmic reticulum and fuse with cis-cisternae of the Golgi complex. Once inside the lumen of the Golgi complex, the proteins are being modified and folded.
The membrane proteins are again packed in vesicles that bud off from the trans-cisternae of Golgi complex and fuse with the plasma membrane to release the proteins. In the presence of the drug that disrupts protein targeting at the trans-face of the Golgi complex, the membrane protein would not be transported to the membrane and would remain in the Golgi complex only.
