Answer:
Blood capillaries
Explanation:
The walls of capillaries are just one cell thick. Capillaries therefore allow the exchange of molecules between the blood and the body's cells - molecules can diffuse across their walls. This exchange of molecules is not possible across the walls of other types of blood vessel.
Answer:
See explanation
Explanation:
Recall that;
Speed = Distance/time
Distance = Speed * time
Speed = 200 km/h
Time = 4 hours
Distance = 200 km/h * 4 hours = 800 kilometres
Displacement has to do with distance covered in a specified direction, in this case, the direction is towards Zambales.
Hence, the displacement is 800 kilometres towards Zambales.
