Answer:
Barroreceptors are specific type of receptors that are present within the membrane or wells of the blood vessels and monitor the changes occur in blood pressure.
The major and important barroreceptors are located in carotid sinus and the aorta for detecting fluctuation in the blood pressure. If blood pressure falls these receptors firing rate decreases and barroceptors reflexes act to increase heart rate in order to restore blood pressure in an individual.
Thus, the correct answer would be - increasing heart rate.
Scientists
can also glimpse the awful effects of Alzheimer's disease when they look at
brain tissue beneath the microscope:
Alzheimer's tissue has numerous fewer nerve
cells and synapses than a well brain.
<span>
<span>Plaques, unusual
clusters of protein particle, which are construct up between nerve cells.</span>
</span>
<span>
<span><span>Dead and dying nerve cells contain tangles,</span> which
are produce of twisted strands of a further protein.</span>
</span>
<span>Scientists
are not absolutely sure what causes cell death and tissue deficiency in the
Alzheimer's brain, but plaques and tangles are key suspects.</span>
The sun's endothermic or exothermic energy has a different, but distinct actions with Earth, which makes them suitable for each other. With the sun's endothermic energy, Photosynthesis occurs in plants, it helps plants absorb heat energy from the sunlight, which lets the plants convert carbon into oxygen and glucose. While the exothermic energy, causes rain. It lets the condensation process of water vapor release energy in the form of heat, which causes rainfall.
