IN ENGLISH
As we know, the strength of wood is different in each direction (i.e. tangential vs radial). Other factors that can influence the strength of a given piece of wood include: specific gravity, moisture content, knots, and slope of grain.
IN RUSSIAN (на русском)
Как мы знаем, прочность древесины в каждом направлении разная (т.е. тангенциальная и радиальная). Другие факторы, которые могут повлиять на прочность данного куска дерева, включают: удельный вес, влажность.

Explanation:
The compound that is a metabolic intermediate of the light-independent reactions in photosynthesis is explained as 3-PGA.
Not sure what you mean by 2 and 3, but sugars such as these use a lot of carbon and hydrogen!
Cellular respiration is the process by which cells obtain energy from glucose. It can be represented by a chemical reaction which, when balanced, obeys the Law of Conservation of Matter:
C6H1206 + 6O2 ---- 6CO2 + 6H2O
Th number of atoms of reactants equals the number of atoms of products:
six carbon atoms, 12 hydrogen atoms, 18 oxygen atoms
No atoms are created or destroyed in this process, they're just rearranged into different molecules.
We often hear the term "burn" to describe glucose being used by living things for energy. When a substance burns, matter is conserved. It might seem like the burned substance is completely consumed because the products, CO2 and water, are both produced in the gaseous form and are colorless and invisible. The French chemist Antoine Lavoisier was the first to show that mass is conserved in chemical reactions by carrying out combustion reactions in a closed system and capturing the gaseous products.
