Answer:
- transport nutrients into the cell that cannot otherwise cross the phospholipid bilayer
- transport wastes out of the cell that cannot otherwise cross the cell membrane
Explanation:
Cell membrane integral proteins especially trans-membrane proteins facilitate and regulate the movement of particular molecules across the cell membrane. Examples of these molecules are glucose and sodium ions. These molecules are either charged and cannot pass through the hydrophobic lipid layer of the cell membrane and/or are too large to pass through the cell membrane pores (like the aquaporins).Other types of cell membrane proteins are peripheral proteins. Collectively these proteins can have several other functions include cell signaling, enzymatic activity, cell-to-cell recognition , and etcetera.
The taiga biome is sometimes called a coniferous forest. This is because it is home to many coniferous trees such as pine, spruce, fir, and hemlock.
Taiga biomes are found between 50 and 60 degrees north latitudes. The taiga is the largest land biome on Earth, covering over 15 percent of the Earth's land. A large area of taiga is located in the northernmost forests across Europe, Asia, and North America. The taiga generally has two seasons. The summers are short, moist, and warm. The winters are long, cold, and dry. Most precipitation is in the form of snow, though rain does occur during the summer. Most animals in the tundra hibernate or migrate during the winter. Hawks, bears, foxes, wolves, deer, bats, and chipmunks can be found in the taiga.
