Answer:
The validity of data, claims, hypotheses, and observations.
Explanation:
Making an argument and discussion over the scientific arguments are considered important to the scientific method. 
The argument should be made in a way that it should check the validity of the hypothesis. The scientist who has to make an argument should consider various steps of scientific method like hypothesis which should predict the explanation of the natural phenomenon.
The person should consider the validity of the data whether it supports the hypothesis or not and observation of the experiment.
Thus, the selected option is the correct answer.
 
        
             
        
        
        
Answer:
Parasympathetic nervous system effects are slow or inhibit function, where is sympathetic, is responsible for the intense physical activity.
Explanation:
The autonomic nervous system or ANS is divided into 2 distinct systems on the basis of their effects- the parasympathetic nervous system and the sympathetic nervous system.
 Both of these have opposite actions on the functions that they maintain.
The sympathetic nervous system regulates the body for a high level of physical activity and also known as fight or flight. It fasts the functions of the body according to the situation.
The parasympathetic nervous system is having the opposite effect of the sympathetic nervous system slows high energy functions and relaxes the body.  
Thus, the comparison of these nervous systems is mention above. 
 
        
                    
             
        
        
        
Solución: El problema indica que se le están suministrando 700 calorías de calor, eso quiere decir que Delta Q será positivo, por otra parte nos dice que al sistema se le aplicará un trabajo de 900 Joules, aquí el signo de Delta W tendrá que ser negativo, puesto que se la están aplicando al sistema.
Sabiendo ese análisis podemos dar solución al problema de la siguiente forma:
        
             
        
        
        
Answer:
0.1
Explanation:
The Net Reproduction per individual per unit time (r) can be calculated as (births-deaths)/population size
Given that:
 Population size of mice = 1,000; Birth = 500; Death = 400,
Net reproduction rate (r) = (births-deaths)/population size
r = (500 – 400)/1000
r = 100/1000
r = 0.1
The Net reproduction per individual per unit time (r) is 0.1
