Traditionally, veterinarians have waited until cats are at least 6 months old before neutering them. But research shows that healthy kittens can be safely neutered at 6 weeks, or as soon as they weigh 2 pounds.Referred to as early-age, pediatric, or pre-pubertal spay/neuter, the procedure eliminates any chance of an âoops litter,â since female cats can become pregnant as young as 4 months of age.raditionally, veterinarians have waited until cats are at least 6 months old before neutering them.

Carbohydrates are the most abundant class of organic compounds found in living organisms. They originate as products of photosynthesis, an endothermic reductive condensation of carbon dioxide requiring light energy and the pigment chlorophyll. As noted here, the formulas of many carbohydrates can be written as carbon hydrates, Cn(H2O)n, hence their name. The carbohydrates are a major source of metabolic energy, both for plants and for animals that depend on plants for food.
Photosynthesis and cellular respiration are complementary reactions. Cellular respiration is the process by which most cells make energy. The products of photosynthesis, oxygen and glucose, are the reactants of the cellular respiration reaction.In turn, the products of cellular respiration, carbon dioxide and water, are the reactants in photosynthesis.ave.

Green plants, algae and some bacteria can perform photosynthesis and are responsible for oxygenating the Earth's atmosphere.
