Where:

p² = frequency of the homozygous dominant allele
2pq = frequency of the heterozygous allele
q² = frequency of the homozygous recessive allele

2. Population Growth Rate:

The formula to calculate population growth is:

ΔN/Δt = rN

Where:

ΔN/Δt = change in population size over time
r = per capita growth rate
N = population size

3. Photosynthesis Equation:

The general formula for photosynthesis is:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

This represents how plants convert carbon dioxide and water into glucose and oxygen, using light energy.

4. Cellular Respiration Equation:

The chemical equation for cellular respiration is:

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (ATP)

This equation explains how glucose and oxygen are used to produce carbon dioxide, water, and energy in the form of ATP.

5. Mitochondrial Efficiency:

The efficiency of ATP production is calculated using:

% efficiency = (Energy used in ATP production / Total energy released) × 100

This formula helps quantify how much energy from glucose is used to generate ATP in cellular respiration.
