1. Cell starts into mitosis phase of the cell cycle.

2. Helicase begins to break the hydrogen bonds between the nitrogen bases. (The double helix has to be unwound in order to expose the nucleotides)

3. DNA polymerase attach the free-floating nucleotides to the exposed nitrogen bases. (this allows a new DNA strand to be made on the existing one)

4. Free floating nucleotides pair up with exposed nitrogen bases (this is what really builds the new strand, based around the template strand)

5. Two new molecules of DNA are created

Statements:

Adenine

Cytosine (Car in the Garage, Apple in a Tree is a good trick to know how they pair)

DNA

Replication

Double helix

what is the significance of diffusion and osmosis in living organism ?give one example in support of your answer​
olasank [31]

Answer:

Diffusion is the process in which molecules and ions move from a region of high concentration to low concentration. Its also how cells transport waste out of the cell and nutrients into it hence being very crucial. Diffusion also occurs without the expenditure of extra energy using a procedure known as passive transport. (Osmosis is a form of diffusion but deals with water exclusively).

Examples of where diffusion is important;

In the intestines - Digested food molecules such as amino acids and glucose move down the concentration gradient from the intestine into the bloodstream. Wastes such as carbon dioxide or urea travel via diffusion from the body's cells to the bloodstream.

Osmosis plays a major role in living organisms. It aids in the transportation of nutrients from cells to cells and also helps to remove the waste's metabolic products from the cell. The purification of blood in the kidneys is also dependent on the process of osmosis.

Why salivary amylase is active in the mouth, but becomes inactive in the stomach?
Cerrena [4.2K]
It becomes inactive in the stomach because of the stomach having a MUCH greater PH level then the mouth. It is typically 1.0-2.0 in the Stomach which is extremely acidic which causes it to change shape and therefore inactive.

When roots take up mineral ions, they are built up against their concentration gradient. both anion and cation transport utilize
attashe74 [19]
I believe the answer is B, primary active transport. Root hair cells in plant use active transport to absorb mineral ions such as nitrates from the soil. The concentrations of minerals in the soil are lower in the soil than in within the root hair cell, therefore the transport will be against the concentration gradient which does not favor diffusion, therefore the pant has to use active transport.
