Answer:

-heat

Explanation:

Radiation happens when heat moves as energy waves, called infrared waves, directly from its source to something else. This is how the heat from the Sun gets to Earth. In fact, all hot things radiate heat to cooler things. When the heat waves hits the cooler thing, they make the molecules of the cooler object speed up.

Good luck!!

Answer:

Explanation:

Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection. Heat can be transmitted through empty space by thermal radiation often called infrared radiation. This is a type electromagnetic radiation .

Some homeostatic imbalances cause a variable that is normally controlled by negative feedback to be abnormally controlled by pos

tigry1 [53]

Answer:

True

Explanation:

Some deviations from normal homeostasis activate the positive feedback loops to control the conditions which are otherwise regulated by negative feedback mechanisms.

For example, the blood levels of respiratory gases and H+ ions are regulated by a negative feedback system via chemoreceptors. The increased partial pressure of carbon dioxide gas and lowered pH or lowered partial pressure of oxygen in the blood are sense by central and peripheral chemoreceptors which in turn activate the neurons of the dorsal respiratory group (DRG).

The activated DRG triggers an increased in the rate and depth of the breathing to facilitate the inhalation of more oxygen and exhalation of CO2 to restore the normal levels.

However, hypocapnia inactivates the chemoreceptors and does not allow negative feedback to restore the normal CO2 levels in the blood.

Under such conditions, the positive feedback loop stimulates the DRG neurons more strongly in response to the increased partial pressure of CO2 above the normal levels than when the partial pressure of oxygen falls below the normal level. These dangerously lowered oxygen levels may also cause fainting.

What type of tissue is the left ventricle made of? <br> please i need this asap

Marianna [84]

Answer:

Cardiac muscle tissue is a type of tissue due to which left ventricle is formed.

Explanation:

Heart is a main organ of human body due to its function. Its main function is pumping of blood to the lungs and to all parts of the body. For this pumping, special type of tissues are required which has the property of elasticity. Cardiac muscles tissue has the property of contraction and relaxation. Cardiac muscles tissue is also called myocardium.

Viruses acquire an envelope during the maturation step of a cell's viral infection?

Flura [38]

It depends on which virus you are referring to specifically. Viruses come in many shapes and types; their variations are tremendous.

For HIV and Influenza, viruses acquire their envelops after maturation, during the budding off or detachment stage from the host cell.

Hope this helps! :)
