Models can be used to predict or explain events is the statements accurately describe models in science.
Explanation:
- Scientific modeling is also known as a scientific activity. The aim of the modeling can understand easier, define, quantify, visualize. Scientific knowledge gives a common knowledge to everyone.
- Normally, Science is a subject which cannot clearly explain moreover it is to be interpreted. 
- There are different types of models present some of them are mathematical models, graphical models, operational models, etc.
- Scientific models are increasing in the fields of science education and Philosophy of education.
 
 
        
             
        
        
        
Answer:
The correct answer would be - 1. group 2.period 3. less 4. more
Explanation:
elements that have a place with same group contains same number of valence electrons. Thus, they will in general show comparable chemiccal properties.  
At the point when we move over a period at that point number of electrons get added to a similar shell. Therefore, there will be no expansion in size of elements.  
Additionally, metals are the elements that have a place with group 1, 2 and d-block group are otherwise called metals. Metallic character of elements diminishes when we move left to directly in a periodic table.  
As most responsive metals are put on the left half of occasional table.  
Since, size of elements increases on descending the groups. Along these lines, a elements can lose its valence electrons due to the less forrce of ttaraction between valence electrons and its neucleus. 
 
        
             
        
        
        
Biological Organisms: Living things that are capable of reacting to stimuli, reproduction, growth, and homeostasis. Organisms are classified by taxonomy into specified groups such as the multicellular animals, plants, and fungi; or unicellular microorganisms such as a protists, bacteria, and archaea.
