The average size of a cell in the human body is 100 µm, or 100 micrometers.
Answer:
B
Explanation:
because Transpiration is an important part of the water cycle.
What polar bears do to keep their temperature at a steady pace in cold temperatures is that they eat enough food to have a steady source and supply/constant amount of fat. Fat acts as an insulating agent and bears have plenty of it. This also explain why a lot of other animals who live in very cold climates have a lot of fat on their bodies.
Answer:
The mass of salt water is 390 grams
Explanation:
To calculate the mass of salt water, we use the equation:
\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}Density of substance=
Volume of substance
Mass of substance
Density of salt water = 1.30g/cm^31.30g/cm
3
Volume of salt water = 300 mL = 300cm^3300cm
3
(Conversion factor: 1mL=1cm^31mL=1cm
3
)
Putting values in above equation, we get:
\begin{gathered}1.30g/cm^3=\frac{\text{Mass of salt water}}{300cm^3}\\\\\text{Mass of salt water}=(1.30g/cm^3\times 300cm^3)=390g\end{gathered}
1.30g/cm
