One of the major functions of erythrocytes (also known as red blood cells) is to carry blood gases such as oxygen and carbon dioxide around the body. Red blood cells contain the pigment haemoglobin which binds to oxygen and carries it around the body, releasing it and allowing the process of aerobic respiration. 
        
             
        
        
        
Low blood pressure may cause the net hydrostatic pressure of a capillary 
to be less than normal resulting in decreased net filtration pressure.
<h3>What is Pressure?</h3>
This is force applied to a body per unit area and it can be calculated by the 
following below:
Pressure = Force/Area
When the net hydrostatic pressure of a capillary is less than normal, the 
glomerular blood hydrostatic pressure (GBHP) decreases thereby resulting 
in a corresponding decrease in net filtration pressure.

Answer:
It is a definition of demand characteristics. 
Explanation:
The term demand characteristics originated in Martin Orne's work as the test group understood what was the investigation and acted consequently. Thus, the way an experiment is built may lead participants to answer unconsciously to what they believe the researcher wants. When the participants form a notion of where the experiment is heading, they probably behave accordingly. One way to avoid the effects of demand characteristics on research is to use deception and guide participant to act more naturally as they cannot guess the purpose of the experiment.
 
        
                    
             
        
        
        
Answer:
 When water is boiled water molecules changed into vapors when these vapors condensed water changed into liquid.
So it is reversible reaction.
Explanation:
Water molecules are connected through the hydrogen bonding. When water is boiled the kinetic energy of water molecules increased and point is reached when kinetic energy is so high and water molecules overcome the external pressure and escape from the surface. Thus water molecules convert into vapors.
In case of cooling process extra energy is released. Vapors becomes cooled and kinetic energy decreased vapors are changed into liquid state.
 When water is boiled water molecules changed into vapors when these vapors condensed water changed into liquid.
So it is reversible reaction.
 
        
                    
             
        
        
        
Answer:
1 and 4
Explanation:
Streptobacilli are linked together in chains, the bacterium is gram positive and   the generally rod-shape. The genus could be aerobic ( required oxygen for their growth), falcultative anaerobe (in the absence of oxygen, they can switch to fermentation).
