Answer: Their supporting structure would be most likely the MUSCULOSKELETAL SYSTEM of the multicellular organisms.
Explanation:
The musculoskeletal system found in multicellular organisms are made up of structures which provides support, protection and allows for various movements. These structures include:
--> Muscles
--> Cartilage
--> Ligaments
--> Tendons and
--> Joints
Furthermore, Microtubules and microfilaments are the major components of cytoskeleton. They are the structures that gives a cell it's shape and helps organise it's parts. As described in the question, they are elongated structures that cross the cell, giving SUPPORT to the cell, and carries organelles and objects throughout the cell.
Therefore, since the Microfilaments and Microtubules provides support and shape at the cellular level it can be most likened to the musculoskeletal system of multicellular organisms which performs the same functions.
Answer:
When a neuron fires and its electric charge travels down the axon, causing neurotransmitters to be released by the neuron's terminal buttons, an <u>action potential</u> occurs.
Explanation:
An action potential, commonly termed as impulse, can be described as messages which are transferred in electrical form. Action potential are caused due to different electric charges. An action potential is generated by a stimulus which causes transfer of sodium ions into the axons resulting in depolarization of the neuron. To overcome this, potassium ion will enter the cell and an action potential will be generated.
The action potential causes release of the neurotransmitters so that signal messages could be transferred.
Hi, I believe the right answer is letter C, ‘it’s low in carbohydrates‘. In fact , salmon and butter contain no fiber, but salmon is high in protein and contains both vitamin B12 and iron.
