The circulatory and respiratory systems work together to provide cells with oxygen and nutrients and remove waste products such

as carbon dioxide. When you need more oxygen, how does the circulatory system respond?
More blood is sent to the lungs and less to the rest of the body.

The blood vessels to the arms and legs constrict to conserve oxygen

Blood moves more slowly through the organs to carry away more wastes.

The heart beats faster to match the rise in breathing rate.

What are the characteristic of solute plssss po​
valentina_108 [34]

Solute is the substance that dissolves

  • Solute is a minor component
  • Solvent is a major component
  • Solutions is a mixture where the solute is uniformly distributed in the solvent.
  • Solution  is homogeneous mixture that contains particles the size of a typical ion or small molecule.
  • The mass of the solute dissolved per unit volume of solvent is called Concentration
  • Solubility is The concentration of a saturated solution
  • Solutes lower the freezing point and raise the boiling point of a solvent.
  • Saturated Solution is a solution in which no more solid can be dissolved
  • Unsaturated Solution is solution in which more solid can be dissolved
  • Precipitate is a solid that crystallizes out of a saturated solution as it is cooled.

what are structures without a present-day function called? a. homologous c. vestigial b. analogous d. extinct
Lesechka [4]
C. Vestigial. 

A vestigial structure example in out bodies is the Appendix. We don't really need it, it just kind of "hangs out" in our bodies. We evolved to not need it. 

I hope this helped! Let me know if it did not! 
I hope you have a fantastical day!!!XD

A circle with circumference \blue{8}8start color #6495ed, 8, end color #6495ed has an arc with a 288^\circ288
vivado [14]

Answer:

The arc is 6.4 units long.

Explanation:

For a circle of radius R, the circumference is given by:

C = 2*pi*R

If we have a section of this circle defined by an angle θ (such that this section makes an arc), the length of that arc is:

A = (θ/360°)*2*pi*R

and 2*pi*R is the circumference, then we can write the length of the arc as:

A = (θ/360°)*C

qsIn this case, we know that the circumference is equal to 8 units, and the arc has an angle of 288°

Then the length of that arc is:

A = (288°/360°)*C = (288°/360°)*8 = 6.4

The arc is 6.4 units long.
