How does water help living things? Check all that apply.
Triss [41]
Hey there!

The answers would be

A. reproduction
B. temperature regulation
C. oxygen transportation
D. heat absorption
E. nutrient reproduction or ALL OF THE ABOVE

Water keeps all of your organs and cells functioning properly including the reproductive cells (egg, sperm) and reproductive organs (brain, ovaries, uterus, testes, thyroid). It also naturally flushes out toxins in the body. For men, semen production and semen volume can be reduced by not drinking enough water.

Water is intricately involved in numerous functions of the body including the transport of oxygen, nutrients and waste products into and out of the cells.

Water has a high heat capacity (an ability to absorb heat) because for water to increase in temperature, water molecules must be made to move faster within the water; doing this requires breaking hydrogen bonds (the H2 in H2O) and the breaking of hydrogen bonds absorbs heat.

Living organisms need water to survive. Other organisms require water to break down food molecules or generate energy during the respiration process. Water also helps many organisms regulate metabolism and dissolves compounds going into or out of the body.

Hope this helps!

the function a(b) relates The area of a trapezoid with a given height of 12 and one base length of 9 with the length of its othe
gtnhenbr [62]
Solving for b, we have the equation A(b)=12*(b+9)/2 - we cancel out 12 and the 1/2 to get 6(b+9)=A(b) and get 6b+54=A(b). Subtract 54 from both sides to get 6b=A(b)-54 and divide both sides by 6 to get b=A(b)/6-9 = A

Answer: 3¼ hours

Step-by-step explanation:

Number of hours used in baking = 2¾ hours

Number of hours used in cleaning up the kitchen = ½ hour

Therefore, the time used in the kitchen will be the addition of the time used in baking plus the time used in cleaning the kitchen which will be:

= 2¾ + ½

= 2 3/4 + 2/4

= 2 5/4

= 2 + 1¼

= 3¼ hours

Therefore, 3¼ hours was used in the kitchen.
