What is the difference between diffusion and facilitate diffusion
Answer:
Diffusion is the passage of molecules from a high-concentration region of the molecule to a lower-concentration area of the molecule.
Facilitated diffusion is the passage of a molecule with the assistance of a protein channel or carrier from a region of high concentration to an area of lower concentration.

How does Islands formed?Oceanic islands are those islands which rise to the surface of land from the floors of the ocean basins. Continental islands are simply the unsubmerged parts of continental shelf which are entirely surrounded by water from all the sides. Many of the larger islands of the world are of the continental type only.
As volcanoes erupt, they build up different layers of lava which may eventually break the water surface. When the tops of these volcanoes appear above the water level, an island is formed. While the volcano is still beneath the ocean surface, it is known as a seamount. Oceanic islands can form from the different types of volcanoes.

Answer:
Catalase
Explanation:
Catalase is an enzyme that speeds up the breakdown of hydrogen peroxide into water (H2O) and oxygen gas (O2).
A catalyst is a substance that lowers the activation energy required for a chemical reaction, and therefore increases the rate of the reaction without being used up in the process.

Put the steps of DNA Replication in the correct order
Answer: Initiation Elongation and termination
Explanation:
There are three main steps to DNA replication: initiation, elongation, and termination. In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands.
The correct order for DNA replication is B, A, C and D.
During DNA replication, first the DNA double helix break down the middle part between base pairs. The enzyme DNA polymerase moves along the exposed strands and adds complementary nucleotides to each nucleotide in each existing strand.
After that a complementary strand is produced for each of the two strands of the original double helix. Thus two new identical DNA molecules have been produced and the replication process is finally completed.
