Baroreflex is a reflex triggered when a baroreceptor is stimulated. In the human body, baroreceptors are found in the carotid sinuses and the sinus of the aorta. These receptors are stimulated during changes in blood pressure. Baroreceptors are sensitive to the stretching of blood vessels.
As blood pressure rises, baroreceptors transmit nerve impulses to the vasomotor center of the medulla oblongata, which is then inhibited. This results in vasodilatation of the blood vessels to reduce blood pressure.
Answer:
Dinoflagellates
Explanation:
Protists are unicellular eukaryotes and dinoflagellates is a protist that is responsible for causing annual Florida red tides. When a large amount of dinoflagellates accumulates in the ocean they make the sea color red which is also called an algal bloom.
They also secrete a toxin that kills lots of aquatic animals. They are also toxic to other creatures like birds, humans. They come together to reproduce in a definite area therefore they accumulate together in large amounts causing red tides annually. Therefore the correct answer is dinoflagellates.
Muscle fibers can be divided into two general categories: Category I, which is sluggish, and Type II, which is quick.There are three primary fiber types in type II, which is further divided into type IIA (oxidative) and type IIX (glycolytic).These fibers exhibit comparatively unique features in terms of metabolism, contractility, and motor units.
