Answer:
The answer is 3:2
Explanation:
A cubic cell has 6 sides
= 6 side²
= 6 × 4²
= 6 × 16
= 96 mm²
Volume of a cubic cell
= side³
= 4³
= 64 mm³
The ratio of the surface area to volume of imaginary cubic cell is therefore:
= 96/64
= 3/2
= 3:2

Its function is to provide rigidity and turgidity. It also stores proteins, food, etc.
Thunderstorms
Layers of warm, moist air rise in a strong updraft to cooler areas of the atmosphere, whereupon thunderstorms form. At that location, the updraft's moisture condenses to create imposing cumulonimbus clouds and, eventually, precipitation.
Thunderstorm development requires three basic components: moisture, an unstable atmosphere, and a method to get the atmosphere moving. To create thunderstorm clouds and precipitation, moisture is required.
The warm air cools and condenses as it ascends, generating tiny water droplets. When there is sufficient instability in the atmosphere, warm air rises swiftly, and the water vapor condenses quickly to form cumulonimbus clouds. Usually, it takes less than an hour for these cumulonimbus clouds to form.

The answer is responsiveness.
Answer:
A myosin head bound to actin
Explanation:
Cross bridge cycling explains the sliding filament theory according to which thin and thick filament slide against each other for muscle contraction. The two myosin heads extend form the thick filament. One myosin head has binding site for ATP and other head has binding site for actin from thin filament.
When myosin head binds to actin a cross bridge is formed. When ATP binds to the other head the bridge dissociates. Actin binding site is free and myosin tries to bind with other actin during which ATP is hydrolysed into ADP and Pi. Myosin along with the ADP and free Pi successfully binds to another actin molecule. The cross bridge formed generates a powerful force and ADP and Pi are displaced from it. The cross bridge is now free again for binding of next ATP molecule and the cycle continues.
