Answer:
A. cell walls
Explanation:
Plants have cell walls but animals dont.
If each side is 0.1 feet extra,
The volume will be 5.1*2.1*1.1= about 11.781.

Kinetic energy is the energy of motion.
The formula for kinetic energy is given as
KE = (0.5) m v²
where m = mass of object , v = speed of object.
an object having some speed and mass will have kinetic energy while an object at rest will not have any kinetic energy since the speed of object at rest is zero.
Since at rest speed is zero. an object has kinetic energy only when it is in motion.
The object D is made up of material Lead. The correct option is D.
<h3>What is specific heat?</h3>
The specific heat is the amount of heat required to change the temperature by 1°C. It is denoted by C.
Two 1-kg objects, C and D, increase in temperature by the same amount, but the thermal energy transfer of object C is greater than the thermal energy transfer of object D. The object C has a specific heat of 235 J/kg-K.
Q = m C ΔT
Qc > Qd
The energy transfer is proportional to specific heat.
Specific heat of D must be less. The possible material with specific heat less than the given value is for Lead material.
Thus, the correct option is D.
