I'm wondering, is a cat smarter than a dog? i mean if you train the dog maybe. but without training?

Well, you have to be a bit more specific. Dog brains among breeds vary in size and capability. Dogs have roughly the same intelligence as raccoons and lions. Meanwhile, the average house cat compares to a bear in intelligence. All in all, some dogs are more intelligent than cats. However, I used to have a cat that could literally communicate through hand gestures and understand us, so it doesn't apply to every dog or every cat.

The answer is constant.

Glucose, also called grape sugar, blood sugar or corn sugar, is among the simplest and one of the primary naturally occurring sugars. produced naturally by plants as the primary photosynthesis product, it is heavily used by living beings as a main energy source and is necessary for cellular respiration. chemically, it is a monosaccharide carbohydrate and serves as a building block for complex sugars like starch.
