As the model is a easy description to  show the structure or working of an object  system or concept, as it has some advantages  and weaknesses too which are.

<u>ADVANTAGES:</u>  

it allows scientists to analyse and simplify complex system,input can be changed and  outcomes can be observed without waiting  for the actual event,and last but not the least  results can be shown to the scientists an to  the public.

<u>WEAKNESSES: </u>

they may not be accurate as climate models are highly complex  in number of factors and accuracy is lost in  the process of oversimplification, they depend on the expertise  of the people making them,and different people expound them  in different ways.

Answer:

See the answer below

Explanation:

First, let us look at the complete equation of respiration:

C_6H_1_2O_6 + 6O_2 -->6CO_2 + 6H_2O

The respective number of each atom in the reactants and the products can be filled in the table thus:

Types of atom   Number of atom in reactants   Number of atom in products

Carbon                                6                                                    6

Hydrogen                            12                                                   12

Oxygen                               18                                                    18

<em>The total number of each atom in the reactants is equal to the total number in the products. Hence, the calculation confirms the law of conservation of matter that says that matters can neither be created nor destroyed, but can be converted from one form to another in a course of a reaction. </em>

All these belong to the second line of defense except
babunello [35]

Answer:

Option D, Gastric Juices

Explanation:

The second line of defense is a non specific defense mechanism in which no specific individual is targeted but all invaders are killed in general way. Some common mode of second line of defense are - Phagocytic cells (white blood cells), inflammatory responses, macrophage system etc. The second line of defense comes into action when the invader has surpassed the first line of defense which include either physical barrier like skin, mucous membrane, hair, cilia etc. or chemical barriers like gastric juices, saliva, Hyaluronic acid etc.

Hence, gastric juice does not belong to second line of defense.

Thus, option D is correct.
