Answer:
The binding of chemical messengers to receptors often results in a shape change, which affects receptor function.
Explanation:
Binding of specific chemical messengers to the corresponding receptors of target cells brings about change in the shape of the receptors. This structural change in the receptor results in the generation of the desired response. It reflects how the form and specific configuration of substances or biomolecules affect their functions.
For example, binding of neurotransmitters to the receptors present on neurons opens the associated ligand-gated ion channels to allow the movement of specific ions through it. In the absence of bound ligand, these channels are present in a closed conformation.
Answer:
The characteristics that best describe SIADH is the ones explains below
Explanation:
(SIADH) or known as syndrome of inappropriate secretion of antidiuretic hormone is a disorder of impaired water excretion caused by the inability to suppress the secretion of antidiuretic hormone.
The characteristics that best describe SIADH is: Fluid retention, serum hypoosmolality, dilutional hyponatremia, and concentrated urine with normal intravascular volume
.
Hydrocarbons is the simplest organic compound mad by hydrogen and carbon
Answer:
As the type of investigation is not discussed, lets answer the question generally.
Explanation:
One of the properties of water is that water in the form of ice is less dense as compared to water liquid water. This property of water lets fishes survive in conditions when the temperature is freezing.
The hydrogen bonds in water make the water turn into a vast, honeycomb structure when the temperature is below 4 degrees Celsius. This causes the ice to float on water and the fishes can stay alive in the liquid water underneath the ice.
