Functional Group
Molecules are chemicals. A particular chemical posses a characteristic feature of forming an unique product when it undergoes chemical reaction along with another chemical. So to identify the chemical "A", one may use chemical "B" or "X" to react with chemial "A" to identify the formation of a product "AB" or "AX". This may many times evident by changes in color.
The cell wall is a common feature to prokaryotic and plant cells.
no
Auricle is the external feature of ear that contains the helix and lobule.
Enzymes are specific: -they only speed up one type of reaction. -they will work over and over and over again until they've been denatured. -you can denature an enzyme with: heat, acid and base. -the structure of an enzyme determines its job.
The feature of an enzyme that determines its chemical process it aids is it's shape. This can be compared to a lock and key. Where an enzyme, as the key, must have a certain structure or multi-dimensional shape that matches a specific section of the substrate, the compound or substance that undergoes the change.
Yes.

The difference between chemical compounds and simple mixtures is that chemical compounds feature two or more atoms that are chemically bonded together. The elements in the chemical compound cannot be separated by "non-chemical" means; physicalmethods won't separate them. Mixtures can be separated without using chemical methods. Let's look at an example with iron and iodine. If we mix iron and iodine, the iron can be "sorted out" from the iodine with a magnet. The magnetic iron particles will be attracted to the magnet, and the iodine will not. That's because the two elements are not bonded together in the mixture; they're just "mixed" together. In the compound iron iodide, however, the iron atoms are bonded to iodine atoms. A magnet cannot be used to separate the two substances in the chemical compound we know as iron iodide. Only a chemical reaction can divide the molecules into their elemental constituents.
The compound DC motor has the advantage of both, constant speed feature of the shunt motor and the capability to handle high starting torque feature of series motor.
The major factor that determines the metabolic rate is the amount of lean body tissue. A feature of the basal metabolic rate is pregnancy increases the BMR.
The websites that feature chemical equations are Khan Academy and 'Chemistry 4 Kidz'. These two websites are the best websites for learning chemistry the fun way.
