Answer: the factors that increase cardiac output include:

--> Nervous stimulation and

--> Hypertrophy of the heart.

Explanation:

Cardiac output can be defined as the quantity of blood pumped into the aorta each minute by the heart. This is also the quantity of blood that flows through the circulation. There are factors that can cause increased cardiac output or that can lead to a hypereffective heart. They are:

--> NERVOUS STIMULATION: The combination of sympathetic stimulation and parasympathetic inhibition does two things to increase the pumping effectiveness or cardiac output of the heart. These include:

• it greatly increase the heart rate from the normal level of 72 beats/mum up to 180 to 200 beats /mom.

• it increases the strength of heart contraction, which is called increased contractility to twice it's normal strength.

--> HYPERTROPHY OF THE HEART: A long term increased workload, but not so much excess load that it damages the heart, causes the heart muscle to increase in mass and contractile strength in the same way that heavy exercise causes skeletal muscles to hypertrophy. This effect of increased muscle mass of the heart, allows the heart to pump much greater than usual amounts of cardiac output.

In an ionic compound, the attraction between actions and _________ hold the compound together
Nady [450]
Answer: 
            The correct option in blank is anion.

Explanation:
                  Ionic compound is formed by the transfer of electron from one atom to another atom. When an electropositve atom lose an electron it form cation, whereas as anion is formed when an atom gain an electron. These actions and anions then attract each other and form an ionic compound.
I hope it will help you.

Example:
              The formation of NaCl is best example of ionic compound. Na has one electron in its outer most shell which can easily be removed to form Na+, while Cl has seven electron in its outer most shell so it can easily gain an electron lost by Na to form Cl-. Then these ions attract each other and form NaCl as shown in the figure.

Which is the most efficient way to avoid DNA mutations from UV radiation?
Natasha_Volkova [10]

The most effective way to prevent DNA mutation from UV radiation is: (C.) Avoid UV radiation by wearing sunscreen.

Mutation is the change in the normal sequence of DNA. The agents that induce these mutations are called mutagens. The mutations can be harmful as they can hamper the normal functioning of the living body. Some mutations however do not cause any significant changes and they are therefore called silent mutations.

Sunscreen is a a cream or liquid applied to the skin that prevents the harmful radiations of the sun to enter the body. They protect from the sun's UV-A and UV-B radiations.
