Answer:
- <u>Medullary hormones</u>: the epineprhin and the norepineprhin. <u>Five different effects that these hormones produce are:</u> increase heart rate, produce cardiac muscle contraction, elevate blood preasure, increase breathing, dicrease digestive activity, increase metabolic rate. 
- <u>The most important mineralocorticoid secreted by the adrenal cortex: </u>aldosterone.
- <u>Actions of the aldosterone: 1. </u>Conserves sodioum ions and water in kidneys. 2. Excrete potasium ions 3. Conserves H2O.
Explanation:
The epineprhin and norepineprhin are the most important medullary hormons. They are so important because of the functions that they have. They are responsable for the increase of heart rate and if it´s movement, along with digestive and metabolic activity.
Thanks to the aldosterone which is the most important secreted minaralocoricoid, kidneys conserve water and sodium and eliminate posatium.
 
        
             
        
        
        
Answer:
the answer is Newton's third and Second law
Explanation:
Newton's second law tells us that the force that is generated on a body is proportional to the acceleration it acquires.
F= M*A
at lower mass greater acceleration
 Newton's third law explains that for each force that acts on a body, it performs a force of equal intensity and direction but in the opposite direction to the body than gender.

Answer:
To determine the effect of toxin binding, you perform a Competitive Binding Experiment
Explanation:
Competitive binding experiments are very relevant when matters relating to cellular and or molecular toxicity are concerned.
 They are used to determine the binding of a single concentration of labeled ligand in the presence of various concentrations of unlabeled ligand. 
They are important because:
1. Validate a direct binding assay
2. Confirm whether or not a drug binds to the receptor
3. determine and explore how low-affinity drugs and receptors interact and it's resultant effects
