25. according to the national institute of health, shock happens when blood pressure drops and blood and oxygen flow decreases to your organs and tissues. causes of shock include internal or external bleeding, dehydration, burns, or severe vomiting and/or diarrhea. all of these involve the loss of large amounts of body fluids. shock often accompanies injury.

why would the loss of large amounts of body fluids result in low blood pressure?

a. it will decrease blood volume, increasing the flow rate of blood.
b. it will increase blood volume, increasing the flow rate of blood.
c. it will decrease blood volume, reducing the flow rate of blood.
d. it will increase blood volume, reducing the flow rate of blood.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
