Answer: Energy transfer is the movement of energy from one location to another. Energy transformation is when energy changes from one type to another. While energy can be transferred or transformed, the total energy always remains the same.
Answer:
C. The cells in these two areas have different functions.
Explanation:
The plant tissues are classified into three major systems: vascular, epidermic, and root systems. The vascular system is formed by tissues referred to as xylem and phloem. The epidermis is composed of superficial tissues that cover plant organs (i.e., leaves, stem, roots, etc). Finally, the root system is formed by tissues whose function is to supply to other plant tissues and store nutrients. Moreover, the plant tissues are also classified into meristematic and permanent tissues. In this case, it is reasonable to suppose that structurally different plant cells that are located at different areas of the plant will have distinct functions.
Answer:
C. Osmosis
Explanation:
Osmosis is the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane. Osmosis is a very useful for moving materials in and out of the cell.
Solutions are mixtures of solutes and solvents. The main aim of osmosis is for all the mixture part to be uniform and the solvent equally dispersed to all the part of the solution.
Osmosis is controlled to a large extent by concentration gradient.
Diffusion on the otherhand is the movement of molecules of a substance from one position to another.
Facilitated diffusion and active transport are just mechanisms for transport within a cell or a body.
Answer:
In most trees, the area just under the bark layer contains moisture in the form of sap and water. And since water is a better electrical conductor than wood, lightning striking a tree tends to travel just underneath the bark.
Answer:Just because two dogs complement each other in physical appearance does not mean they will complement each other when comparing pedigrees. As spoken so well by my mentor, breeding is an art. When doing a breeding, stick to the breed standard, and strive for perfection
