Answer:
D) (CH2O)n, where n can be 3-7
Explanation:
Monosaccharides are the simplest carbohydrate that has a formula of (CH2O)n where n at least have to be 3. Since its the simplest form, monosaccharides can't be broken down into smaller carbohydrates.
If the number of n is less than 3, it won't become monosaccharides. A molecule with CH2O formula is called an aldehyde. That is why option C is wrong. The answer will be option D
Well, DNA is just a big recipe for all kinds of proteins. So your DNA will determine what proteins are made in each organism. There can be slight differences in the recipes - for example all humans have the recipe for hair, but our recipes are just a bit different - thus the different hair colors we all have.
It is true that rock layers can be correlated to each other by using fossils and matching layers.
This is because these rocks have similar, if not the same layers, which can easily be determined by the fossils that may appear on them and just using them to match the layers to see if they can correlate.
Answer: C. i. potential, ii. kinetic, iii. potential and kinetic
Explanation: Potential energy is the energy that is possessed or exhibited by an object or a body that is static or stable. THE FORMULA FOR POTENTIAL ENERGY IS P.E = MASS OF AN OBJECT* HEIGHT * FORCE OF GRAVITY
Kinetic energy is the energy of an object or a body that is in motion or it is moving from one point to another.
THE FORMULAR FOR KINETIC ENERGY IS 1/2*MASS OF AN OBJECT *VELOCITY OF THE OBJECT SQUARE.
