As mean arterial pressure increases, <u>the frequency of action potentials from the </u><u>baroreceptors</u><u> increases,</u> informing the medulla oblongata that blood pressure has indeed increased.

  • Special receptors called baroreceptors monitor variations in your blood pressure.
  • The aorta and carotid sinus both contain significant baroreceptors. The walls of the arteries stretch when the blood pressure in the aorta or carotid sinus rises, stimulating an increase in baroreceptor activity.
  • Action potentials are more quickly fired when baroreceptors are activated, with the speed being inversely correlated with the mechanical stretch.
  • The brain interprets the information that the baroreceptors send as a rise in blood pressure.
  • The blood vessels, heart, and kidneys are just a few of the bodily organs that get signals from the brain to lower blood pressure.

Diffusion, Osmosis and Enzymes
Nana76 [90]

The given statements can be matched as following:

a)The diffusion of water from a high concentration to a low concentration  - Osmosis

b)Lowers the amount of energy needed to perform chemical reactions - Enzymes

c)When you breath O2 passes into your blood stream while CO2 passes out of your blood stream -Simple Diffusion

d)Involved with, but does not become a part of chemical reactions -Enzymes

e)Small molecules with no charge can move through semi-permeable membranes by this process- Simple Diffusion

Explanation:

a) Osmosis is generally defined as the process by which water is transported from a region of Higher concentration to the region of Lower concentration.

b) Enzymes are well known to reduce the amount of energy required or needed for a chemical reaction to take place.

c)The process by which oxygen passes through our blood stream and carbondioxide passes through the other is known as simple diffusion process.

d) Enzymes are ones that actively gets involved in the chemical reaction but they will never become a part of that chemical reaction.

e) Diffusion is the process by which very small molecules that carries no charge moves through semi permeable membrane.

PolarNik [594]

<u>Answer:</u> The correct answer is Option C.

<u>Explanation:</u>

Precision refers to the closeness of two or more measurements to each other.

For Example: If you weigh a given substance five times and you get 3.2 kg each time. Then the measurement is very precise.  

Accuracy refers to the closeness of a measured value to a standard or known value.

For Example: If the mass of a substance is 32 kg and one person weighed 31 kg and another person weighed 29 kg. Then, the weight measured by first person is more accurate.

According to the question:

Mass weighed by Mary = 10.00 g

Mass weighed by Tommy = 10 g

As, mass weighed by Mary is reported upto 2 decimal places. Thus, it is more precise.

Hence, the correct answer is Option C.
