What is the adaptive advantage of an earthworm's response to light and moisture?

Because earthworms are sensitive to light, they usually spend their days in the ground or in leaf litter. This sensitivity is an advantage to them because, if they spent their days in the sunlight, they would dehydrate and die.

In a conditioning experiment what behavioral state is reached when the stimulus no longer evokes a response?
Denying the expected reward for response to a stimulus will eventually result in the "extinction" of the conditioned behavioral response.
An animal is an immediate automatic response to an external stimulus?
An animal's immediate automatic response to an external stimulus will vary depending on the circumstance. When the external environment is stimulated there is a response that is triggered.

What characteristic describes a long term response to the environment?
adaptation
What is a response that feeds back to reverse the changes caused by the original stimulus?
Negative feedback is the response to changes in stimuli that reverts the change back to the normal stimuli.
What is an example of an adaptive response?
A response to adapt to a situation...for example fear could create an adaptive response to "fight or flee", or could paralyze the person into inaction.
Specific immunological response?
adaptive immune response
Is Adaptive response is the accommodation of an individual organism to its environment?
True
What mobilizes the adaptive defenses and provokes an immune response?
Antigens
Is the adaptive value of the spinal reflex due to speed of response?
Yes.
What part of the adaptive immune response involves B cells?
Humoral
Explain why the ability to rapidly degrade mRNA can be an adaptive advantage for prokaryotes?
Prokaryotic mRNA molecules are degraded by enzymes after only a few minutes . Thus bacteria can quickly alter patterns of protein synthesis in response to environmental changes.
What is the full form of AMR?
1) Adaptive Multi-Rate 2) American Medical Response
Which cell of the immune system is absolutely required for an adaptive immune response?
T helper cells
What are examples of an organisms responding to there environment?
The earthworms have a layer of film on their body to help them retain moisture to live in the soil. There response to touch helps the worm protect themselves, find food, and also to find mates.
What is innate defenses mean?
recognizes all antigens ( anything that induces a specific and adaptive immune response)
What is adaptive thermogenesis?
Adaptive Thermogenesis: This can be defined as the regulated production of heat in response to environmental changes in temperature and diet, resulting in metabolic inefficiency. For example, shivering when we are cold uses energy and this is an example of adaptive thermogenesis. (Alexander Bowring 24 / 04 / 2008)
