What does the breakdown of rhodopsin cause?
The breakdown of rhodopsin causes activation of the visual signaling pathway in response to light. This ultimately leads to the generation of electrical signals that are transmitted to the brain for image processing and vision.
What happens to the comets tail as it passes the sun?
As a comet approaches the Sun, the heat causes ice and other volatile substances within the comet to vaporize. This forms a glowing coma (a cloud of gas and dust) around the solid nucleus of the comet. The solar wind then pushes this gas and dust away from the Sun, forming a tail that can stretch for millions of kilometers in the opposite direction of the Sun.
If the nucleus of a radium-226 atom is unstable what causes the nucleus to spontaneously decay?
Instability is due to a certain ratio between neutrons and protons in the atomic nucleus.
What is a thing of event that causes a response or reaction?
stimulus
What causes arterioles to dilate in response to increased sympathetic tone?
Increased sympathetic tone leads to the release of norepinephrine, which binds to alpha-1 adrenergic receptors on arteriolar smooth muscle. This binding initiates a signaling cascade that ultimately results in the relaxation of the smooth muscle, causing the arterioles to dilate.
What does the breakdown of rhodopsin cause?
The breakdown of rhodopsin causes activation of the visual signaling pathway in response to light. This ultimately leads to the generation of electrical signals that are transmitted to the brain for image processing and vision.
What is the difference between a positive and negative response in biology?
A positive response is when a response happens to a stimuli, and this response causes more of the stimuli to happen. A negative response is when a response happens because of a stimuli, and the response stops the continuation of the stimuli.
What is a factor that causes a response?
A stimulus is a factor that causes a response in an organism.
What causes responses?
a stimulus causes a response
What is up- regulation and down- regulation and what causes them?
Up-regulation refers to the increase in the number or sensitivity of receptors in response to a decrease in signaling molecules, leading to increased cell responsiveness. Down-regulation is the opposite, where the number or sensitivity of receptors decreases in response to an excess of signaling molecules, thus reducing cell responsiveness. These changes are typically caused by fluctuations in the levels of signaling molecules or prolonged exposure to a stimulus.
What the difference between reaction and response?
A reaction is what happens to the body when a stimulus is applied, a response is what happens next; i.e a stimulus illicits a reaction which illicits a respose. For example, glucose in the blood (a stimulus) causes the pancreas to release insulin (a reaction), which in turn causes the cells to take up glucose from the blood (a response).
What causes the immune response?
an antigen
What is anything that causes a response?
A stimulus.
What are the causes of decay?
An unstable nucleus, which can be caused by:excess of neutronsshortage of neutronsmetastable excited state of nucleus
What is a change in the environment that causes a. Response?
stimulus
What are the causes of non-sampling errors?
non response, in accurate response and selection bias
Is the action that causes a response?
Yes, an action is typically the stimulus that triggers a response in a system or organism. In the context of cause and effect, the action is what instigates the reaction or outcome.
