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.

Some limiting factors that the Orca population experienced while in captivity include food and dissolved oxygen.
<h3>What is Limiting factor?</h3>
This refers to any variable or factor in the environment which limits the population expansion of a given species.
In the case of Orca they are present in the sea and need food and dissolved oxygen to survive which is why it acts as a limiting factor due to their absence causing a decline in population.

Answer:
Explanation:
Positive phototropism is growth toward a light source, and negative phototropism is growth away from a light source. ... Sunflowers are a great example of positive phototropism, because not only do their stems curve toward the light but their flowers turn to face the sunlight as well.
