Osmosis is the specific movement of solvent molecules through a semi-permeable membrane, while diffusion is the general movement of particles from high to low concentration in any medium.
Osmosis and diffusion are both fundamental processes of passive transport. Osmosis is a subset of diffusion that specifically involves the movement of solvent molecules, usually water, through a semi-permeable membrane to equalize solute concentrations on both sides of the membrane. It's essential in processes like maintaining cell turgidity.
On the other hand, diffusion encompasses the broader concept of particles, including solutes and gases, spreading out from areas of high concentration to low concentration. It occurs in various environments, not limited to membranes, and is vital for processes like gas exchange in respiration and the distribution of nutrients in cells.

Answer:
Adenosine triphosphate (ATP) is an essential biomolecule that stores and provides chemical energy in living organisms. It acts as a "currency" for energy transfer within cells. Let's break down its structure and function:
1. Structure: ATP is composed of three main components:
a. Adenine base: It's a nitrogen-containing molecule that serves as a building block of nucleotides.
b. Ribose sugar: This is a five-carbon sugar molecule that is bonded to the adenine base.
c. Phosphate groups: ATP has three phosphate groups attached to the ribose sugar.
2. Energy Storage: The energy in ATP is stored in the bonds between the phosphate groups. These bonds are high-energy bonds, meaning they contain a lot of potential energy.
3. Energy Release: When the cell needs energy, ATP can be hydrolyzed, or broken down, by removing one phosphate group. This results in the formation of adenosine diphosphate (ADP) and an inorganic phosphate molecule. The breaking of this bond releases energy that can be used by the cell for various processes.
4. Recycling ATP: ADP can be further hydrolyzed to form adenosine monophosphate (AMP) by removing another phosphate group, but this reaction releases less energy compared to the conversion of ATP to ADP. ATP can be regenerated by adding a phosphate group back to ADP through a process called phosphorylation. This recycling process allows ATP to continuously provide energy within the cell.
To summarize, ATP is a molecule that stores and provides chemical energy in cells. It consists of an adenine base, ribose sugar, and three phosphate groups. Energy is released when ATP is converted to ADP by breaking the bond between the second and third phosphate groups. ADP can be further converted to AMP, but with less energy release. Through phosphorylation, ADP can be converted back to ATP, ensuring a continuous supply of energy for cellular process

A.)in the reverse direction of the strip of magnetized rock next to it
B.)to match the polarity of the strip of magnetized rock next to it
C.)according to Earth’s existing magnetic field
D.)in the reverse direction of Earth’s existing magnetic field
Answer: C.)according to Earth’s existing magnetic field
Explanation:
Earth acts as a huge bar magnet. It has strong magnetic field due to presence of molten iron and nickle present in its outer core. A magnetic object acquires magnetic properties when placed in a magnetic field for a while.
Basalt is a volcanic rock. It is formed due to rapid cooling of lava on the surface of Earth. It contains iron oxides, iron-titanium oxides. Because of these oxides, Basalt can acquire strong magnetic properties. The domains align in the same direction as the Earth's magnetic field.
Thus, when new basalt forms along mid-ocean ridges, it becomes magnetized C.) according to Earth’s existing magnetic field
