Do you have a photo of the problem? :)
Answer:
Symbiosis is a close relationship between two species in which at least one species benefits. For the other species, the relationship may be positive, negative, or neutral. There are three basic types of symbiosis: mutualism, commensalism, and parasitism! Hope this helps! you can simplify this answer!
Explanation:
<u>Answer</u> :- Step 1 Receptors (sense organs, muscles, glands, etc.) receive stimuli from the environment or from inside your body.
Step 2 The central nervous system processes information received from the peripheral nervous system.
Step 3 The central nervous system sends out the processed information to the peripheral nervous system.
Step 4 The peripheral nervous system sends a message to the body part that needs to respond so you can react appropriately to the stimulus.
<u>Explanation</u>:-
- There are two different parts of the nervous sytem-the peripheral nervous system (PNS) and the central nervous sytem (CNS).
- The <em>CNS</em> consists of the brain and the spinal cord .
- The <em>PNS</em> consists of all the nerves that lie outside the CNS.
- The main function of the PNS is to gather information from the <em>sensory receptors</em> located in our body and convey this information to the central nervous system.
- The CNS collects this information from the PNS and then interprets it. The interpreted information is then relayed back to the body parts via the PNS to perform the appropriate action.
D. communication
<span>The neuron, a cell
that composes the nervous system. For example a brain, an organ composed
of thousands of neural fibers and glial cells that performs many
important organismic functions.
Neurons are specialised cells that
have dendrites, axons and terminal buttons that sends and receives
stimuli from the environment and transduces it into a meaningful
information and understand the complexities which the brain now
functions. </span>
Pyramid biomass
<span>Pyramid biomass shows how energy are passed at
each tropics level and it is a graphical representation that shows the extents of
biomass per unit area at different tropic level with an ecological system. Also,
biomass is the food available for the next tropic level in a food chain and
they can be used as a source of renewable energy. </span>
