A scientist wants to test whether the pH, salinity, and temperature of seawater impacts coral development. He sets up an experim
romanna [79]

The conclusion that coral does not grow well in conditions with high salt is invalid because (B)  The experiment changes more than one variable at once.

In these aquariums, only one condition needs to be varied at a time to study its effect. To study the condition with high salt, the temperature and pH needs needs to be kept fixed at a particular value whilst varying the salinity from normal to low to high.

Which of the following statements correctly describe(s) the relationship between the classes of hormones and their behavior or f
balandron [24]

The correct answers are:

• How soluble the hormone is in water. Depending on is it hydrophilic or hydrophobic. For example steroid hormones (derived from lipids) are hydrophobic, meaning that are insoluble in water so they must have transport protein for the blood transport.

• whether the hormone will be able to move through the cell membrane. Hormones derived from lipids are able to pass through the membrane because are able to diffuse through the lipid bilayer. Hydrophilic hormones (from amino acids) are unable to diffuse through the lipid bilayer

• whether the hormone interacts with receptors on the cell membrane.  

• whether the hormone interacts with receptors inside the cell

Hormones that diffuse freely through the membrane have internal receptors. Others have cell membrane receptors.
