Answer:
Physical property is defined as the property of a substance which can be measured without changing its chemical identity. Physical properties are observable properties of a substance. In other words, physical properties can be measured by watching, listening, feel, touch or smell.
Some examples of physical property are: Hard, soft, color, odor, and luster etcetera.
 
        
             
        
        
        
Answer:  
A trans membrane protein is a type of integral protein that is found in the entire cell membrane and the membrane protein is attached to the cell membrane.
Many trans membrane proteins functions as channel or gateway which allows the transport of the specific materials which cannot be transported through other means.
The other materials which cannot be transferred by simple diffusion, osmosis or other means is transported by the trans membrane proteins.
 
        
             
        
        
        
Water be included in the model as a reactant and a product
<u>Explanation:</u>
- Reactants are the one that react together in a chemical equation. The product is the result formed due to the chemical reaction occurring between the reactants. 
- For example if natural gas is burnt the methane and the oxygen are the reactants. The product produced due to the chemical reaction is Carbon dioxide and water as the product. 
- For the production of ADP water acts with ATP to reduce Triphosphate to diphosphate. In this, it is the reactant and in chemical reaction the bonds are broken between the atoms and new bonds are produced between the products.
 
        
             
        
        
        
Gene editing. 
Gene editing, is based 
on a the CRISPR-Cas9 technology. It allows researchers to customize a
living organism’s genetic sequence by making very specific changes to its DNA.
Gene editing has a wide array of applications, being used for the genetic
modification of crop plants and animals.
