Grade 10 Coordinated Science Quiz

1

In which order does the signal for the reflex arc travel?

1

In the lighting circuit in a house, how are lamps usually connected, and what is one reason for this?

1

When the voltage of the supply is reduced, the voltage across the resistor decreases

4

What factors can effect the resistance of a piece of wire?

5

1

The change in blood glucose concentration can be detected by organ A. If it releases hormone B into the blood, hormone B will convert glucose to glycogen and the concentration of glucose in the blood will decrease. If it releases hormone C into the blood, hormone C will stimulate organ D to convert glycogen to glucose and the blood glucose concentration will increase.

NAME ORGAN A AND HORMONES B AND C

2

Why is glucose converted to glycogen rather than just kept as glucose in the cells

3
