Answer the following question given this paragraph: Veins are made primarily of xylem and phloem. They transport water and minerals to the cells of leaves and carry away dissolved sugar. Q: What are xylem and phloem responsible for transporting to the cells of leaves? A:
****
A: water and minerals

Answer the following question given this paragraph: Two species may often interact with each other and have a close relationship. Examples include flowers and the animals that pollinate them. When one of the two species evolves new traits, the other species may evolve matching traits. This is called coevolution . You can see an example of this in Figure below . The very long beak of this hummingbird co-evolved with the tubular flowers it pollinates. Only this species of hummingbird can reach nectar deep in the flowers. Q: What is it called when two species evolve matching traits? A:
OPTIONS:
- Allopatric speciation
- interconnection
- spontaneous mutation
- coevolution
coevolution

Answer the following question given this paragraph: The cytosol is the jelly-like material in which the contents of the cell are suspended. Q: What is the jelly-like material in which the contents of the cell are suspended? A:
OPTIONS:
- jam
- cortisol
- mitochondrial
- cytosol

Answer: cytosol

- roots
- flowers
Answer: flowers

Problem: OPTIONS:
- absorbs extracellular materials
- repels extracellular materials
- destroys extracellular materials
- provides a barrier
Q: Answer the following question given this paragraph: CHAPTER REVIEW 3.1 The Cell Membrane The cell membrane provides a barrier around the cell, separating its internal components from the extracellular environment. It is composed of a phospholipid bilayer, with hydrophobic internal lipid "tails" and hydrophilic external phosphate "heads. " Various membrane proteins are scattered throughout the bilayer, both inserted within it and attached to it peripherally. The cell membrane is selectively permeable, allowing only a limited number of materials to diffuse through its lipid bilayer. All materials that cross the membrane do so using passive (non energy-requiring) or active (energy-requiring) transport processes. During passive transport, materials move by simple diffusion or by facilitated diffusion through the membrane, down their concentration gradient. Water passes through the membrane in a diffusion process called osmosis. During active transport, energy is expended to assist material movement across the membrane in a direction against their concentration gradient. Active transport may take place with the help of protein pumps or through the use of vesicles. Q: How does a cell's membrane keep extracellular materials from mixing with it's internal components? A:
Answer:
provides a barrier
