The blood the reaches the cells from the capillaries food and O2 pass to cells, CO2 and wastes
pass to blood. The rest of the choices do not answer the question above.
Determining if an object will float or sink is based on the density of the object and also the density of the solution, the lower the density, more likely the object is to float, and if the density is higher, therefore the object is heavier and it will sink. In our question we have ebony wood with a density of 1.2, the only possible layer that this material can float is on Chloroform, that has a higher density, therefore the answer is letter A
Answer:
Explanation:
Hello there!
In this case, for this units conversion problem, it turns out necessary to write the equivalence statement for liters and quarts as follows:
1 qt = 0.946353 L
Thus, the conversion set up turns out to be:
Next, we convert to microliters as follows:
Regards!
Answer:
Explanation:
It is a physical change .
If we start from 10 atm of pressure and - 40 celsius of temperature to 20 atm of pressure and 70 celsius of temperature , it is a change in which pressure increases and temperature also increases that means heat is added up to the gas . If we cool the gas we can retrieve its earlier pressure and temperature .
So it is a physical change . In physical change , we can retrieve the old position by simple means.
