The correct answer is: The vasomotor center would increase sympathetic output to arterial smooth muscle to increase TPR.
Baroreceptors are mechanoreceptors (sensors or modified nerve endings) found in the blood vessels and their function is to detect the change in blood pressure and participate in the regulation of it (so that proper blood pressure can be maintained). The action of baroreceptors or baroreflex works as a negative feedback loop: when the blood pressure is decreased, baroreflex activation also decreases (baroreceptors are active even at normal blood pressures) and causes heart rate to increase.
Decreased blood pressure leads to lower baroreceptor “firing” which then results in an increase in sympathetic stimulation of the heart and sympathetic stimulation of the peripheral vessels, resulting in vasoconstriction. As a result blood pressure increase.
Answer:
Lynhenykus Monodactylus is an extinct species of dinosaurs with its origin from Mongolia, also it is one digit possessing dinosaurs, not belonging to the avian group.
Explanation:
Structurally, this type of dinosaurs is small, only some feet in length and is of very light weight. It belongs to the genus namely alvarezsauroid. The typical characteristics of their body is presence of single big sized second digit with forelimbs very short. The digit though large in size but is not so strong enough. They are believed to be insectivorous, thus using its large digit to attack its prey.
One type of density change is mass over volume.
