<h2>Dinoflagellates thrive in bahia fosforescente</h2>
Explanation:
- Dinoflagellate, are one-celled aquatic organisms having two dissimilar flagella.
- It has a characteristics of both plants and animals.
- Most of the dinoflagellates are marine, but some live in freshwater habitats.
- Bahia fosforescente is one of the phosphorescent bays where millions of glowing marine dwellers such as dinoflagellates cause the lake to glow a bright blue in night.
- Dinoflagellates has the characteristics of Bioluminescence which they use it as a defense mechanism.
- During night, due to the bioluminescence of dinoflagellates,water can have an appearance of sparkling light.
- Dinoflagellates takes their nutrients from marine organisms, thus they grow or develop well in bahia fosforescente.
Answer: movement is always voluntary
Explanation:
Muscles are contractile:
- Contractility is the ability of muscle cells to forcefully shorten. Think of having the ability to flex a muscle.
Muscles are excitable:
- Excitable tissue can conduct or transmit electrical impulses. Basically, it can react to stimulus, which may be delivered from a motor neuron or a hormone. For example, the hormone epinephrine helps muscles to produce force.
Muscles respond to stimulus:
- well since muscles are an excitable tissue, they can react to stimulus. (see answer above)
————————
Muscle movement is NOT always voluntary:
- Some muscle movement is voluntary, which means it is under conscious control. For example, a person decides to open a book and read. Other movements are involuntary, meaning they are not under conscious control, such as the contraction of your pupil in bright light, breathing, blinking, your heart beating, etc.
- Therefore, the correct answer is:
movement is always voluntary
