What is an 'Exoskeleton'?

• The hard skin of an insect made of proteins and minerals.

• A hard, protective outer covering made primarily of chitin.

• An outer skeleton made from microscopic metals.

What is a Proboscis used for?

• It is used to grind down food due to small mouth- parts in the Proboscis.

• It is used to catch prey in a lasso-like manner.

• It is used to suck liquids such as Nectar or Blood.

What are Spiracles?

• Spiracles are the part of the respiratory system of insects.

• A Spiracle is an eye of an insect.

Ants and termites are known as _ insects because they live in large groups.

A combination of the Head and Thorax is called the _ . Which is distinct to Arachnids.

What is the difference between Speed and Velocity?

• Speed is faster than velocity.

• Velocity includes direction, while speed doesn't.

• Speed is measured in meters, while velocity is measured in seconds.

• Velocity is always greater than Speed.

What is Newton's first law of motion?

• An object at rest will move on its own.

• Force is equal to Mass times Velocity.

• An object at rest will remain at rest, While an object in motion will continue to move unless acted upon by an external force.

• Gravity only affects objects on Earth.

What is the formula for calculating force?

• Force = Mass/Velocity

• Force = Mass × Acceleration

• Force = Velocity/Time

• Force = Distance × Time

• 40m/s

• 50m/s

• 60m/s

• 800m/s

What type of energy is associated with motion?

• Potential Energy

• Thermal Energy

• Kinetic Energy

• Electrical Energy
