Can start a fire( rubbing to rocks together) and friction is used when you hit the brakes on a car( the pad pushes down on the tire). Good luck!

Friction is useful for walking. We would never stop going. We would constantly be slipping. and clothes would be very difficult

It is also useful for grabbing. Imagine trying to grab an oiled up phone. It would slip out of your hands! Everything would be  like that without friction

Compare the thickness of the right and left ventricles. Which ventricle is thicker the right or left. Explain the difference.
zepelin [54]

Answer:

When comparing the thickness of the heart's ventricles, the left one is thicker than the right one, because it must generate more pressure to pump blood throughout the body.

Explanation:

In the human heart, the right ventricle is in charge of pumping the blood to the lungs —initiating the minor circuit of the circulation— while the left ventricle is in charge of pumping the blood to the whole body.

To fulfill its function, each ventricle has a specific thickness in its walls, the left one being thicker than the right one.

  • <em>The </em><em>right ventricle</em><em> is a chamber that handles more volume than pressure, and its walls are thinner because it does not require much pressure to pump the blood to the lungs. </em>
  • <em>The </em><em>left ventricle has a thicker muscular wall </em><em>because it is a chamber that must generate a high pumping pressure, so its contraction force must be greater. </em>

The structure of the myocardium in the heart is what allows each chamber to fulfill its function adequately.

Fdsci 101 what general trend do you observe relative to the masses of these species? question 3 options: all species basically h
Alexandra [31]

The third and last option is correct.


Species in the past (referring to dinosaurs) were more massive.

\bf~CO_{2} levels where higher in the past, which meant that plants prospered during that time since they had a easy access to food. That contributes to the fact that herbivores could grow bigger because there was more food. Which in turn, increases the size of early carnivores which eat bigger herbivores.




Hope it helped,


Happy homework/ study/ exam!
