Hello!!
In the human digestive system, food enters the mouth and mechanical digestion of the food starts by the action of mastication (chewing), a form of mechanical digestion, and the wetting contact of saliva.
hope this helps!!

Explanation:
Answer: Equation for photosynthesis is carbon dioxide + water + sunlight→ Glucose + oxygen
In light dependent reactions, energy in form of solar energy is absorbed and converted to chemical energy.
Explanation: During photosynthesis, sunlight is absorbed by the light absorbing pigment called chlorophyll. The absorbed solar energy is converted into chemical energy using carbon dioxide and water as the starting materials with the release of oxygen. The equation is 6 CO2 + 6 H2O + solar energy --> C6H12O6 + 6O2.
Photosynthetic reactions are made up of two parts: the light dependent reactions and the carbon fixation reactions. In the light dependent reactions, chlorophyll and other photosynthetic pigments absorb light energy from the sun and conserve it as ATP and NADPH with a simultaneous release of oxygen. The carbon fixation reactions are driven by the products of the light dependent reactions.
Although the operation of natural selection requires that genotypes differ in fitness, for some geneticists it seems easier to understand natural selection than fitness. Partly this reflects the fact that the word “fitness” has been used to mean subtly different things. Here I distinguish among these meanings (e.g., individual versus absolute versus relative fitness) and explain how evolutionary geneticists use fitness to predict changes in the genetic composition
