How does the action og wind affect a rock appearance<br>​
Leona [35]
Wind causes the lifting and transport of lighter particles from a dry soil, leaving behind a surface of coarse grained sand and rocks. The removed particles will be transported to another region where they may form sand dunes on a beach or in a desert. Wind erosion is referred to as eolian erosion. Differences in atmospheric pressure will cause the motion of air that can erode surface material when velocities are high enough to move particles.

Explain the importance of independent and dependent variables in an experiment.
ddd [48]

Answer: Independent variable is what is being modified, it is important to compare it to your control group, (which is the original).

Dependent variable is what is being measured, to compare it to the control group to see if your hypothesis works or not.

Bob wanted to take a mint with a mint drop, and he wanted to measure if it can make his breath fresher, but he also wanted to take it with a regular mint to see which is the freshest breath.

Zielflug [23.3K]

Enzymes are classified and named according to the<u> types of reactions they catalyze.</u>

Explanation:

According to the International Union of Biochemistry and Molecular Biology nomenclature of enzyme classification, enzymes are classified depending upon the reactions they catalyze and how the reaction transforms the substrate and forms new products.

Based on the reactions:

Addition reaction (removal of a water molecule): hydrases or hydrolases like esterases, nucleases etc

Electron transfer reaction: Oxidases and dehydrogenases

Radical transfer reaction: Transglycosidases, transaminases, etc

Splitting or C-C bond formation: Desmolases

Structural or geometrical change: Isomerases

Hydrolysis of phosphate bonds to join molecules: Ligases
