Phloem cell

Nerve Cell

What is this cell and how does its structure enable its function ? *

3 points

Contains lots of mitochondria to enable quick movement

Is branched to connect to other cells

Is bi concave to enable greater surface area for gas exchange

Nerve cell

Red blood cell

Phloem cell

Has a large surface area to enable water to be drawn in via Osmosis

Has a sheath of fat to insulate the electrical impulse

Root hair cell

Skin cell

Is long to cover more distance in the body

Contains no nucleus to maximise Oxygen molecule uptake

Xylem cell

Required

What is the equation for magnification? *

1 point

Image size = Actual size / Magnification

Actual size = Magnification / Image size

Image size = Actual size x Magnification

Actual size = Image size x Magnification

If an object has a KE of 500 Joules, and has a mass of 10kg, what is its velocity? *

0 points

5 m/s

10 m/s

50 m/s

500 m/s

Which of these are adaptations of plant root hair cells? *

1 point

Large surface area

Green colour

What is the correct equation for calculating Kinetic Energy *

1 point

Kinetic energy = ½ x mass x velocity2

Kinetic energy = ½ x mass x distance2

Kinetic energy = ½ x force x velocity2

Kinetic energy = 1/4 x mass x velocity2

Kinetic energy = ½ x weight x velocity2

Kinetic energy is energy an object has due to motion. It depends on two variables: (tick all that apply) *

2 points

Velocity (N/kg)

Mass (kg)

Speed (km/hr)

Speed (m/h)

Weight (kg)

Mass (N)

Weight (N)

Velocity (m/s)
