The given case is an example of reflex action.
The reflex action is an instant involuntary response to a stimuli, which can cause damage. The reflex action takes place through the processing of message through a reflex arc, this reflex arc lack the involvement of brain and the processing of the stimulus takes place in the spinal cord.
In this case, the sensory receptors detects the stimuli and transfer the message to the relay neuron present in the spinal cord through the sensory neuron. The relay neuron transfer the action message to the effector muscles present at the site of stimulus with the help of motor neurons.
Given below is a block diagram of reflex action.
It is an everyday life theory because it is a prediction. Molly doesn't know if she will be the best singer, but can assume that she will be because of her mother She hasn't experimented yet, so, therefore, her theory can't be supported by evidence.
Answer:
able to move using specialized structures
Explanation:
Animal like protists have ability to move with short cilia and flagella. And they get energy from other source. Explanation: Euglena can moves through flagella and can produced its own food.
lol thanks.
(3) carbon, hydrogen, oxygen, and nitrogen
The individual bacteria would appear larger under the magnification of 40X. Thus, the correct option is A.
<h3>What is Magnification?</h3>
Magnification may be defined as the power of a microscope to deliver an image of an entity at a scale larger and sometimes smaller than its genuine size.
Bacillus subtilis is a distinct germ, that is rod-shaped in structure and is Gram-positive. Under the 40X microscope, it looks as rough, opaque, fuzzy white, or narrowly yellow with irregular edges.
The size of the entity or any object under the microscope of 40X magnification is 5mm, while the of the entity or any object under the microscope of 10X magnification is 1-2mm.
Therefore, it is well described above.
