Identify the 2 major groups of enzymes that make the redox reactions possible: Describe their role in these reactions.
adell [148]

Answer:Enzymes that makes redox reactions possible in a biochemical process includes those that help to catalyze the transfer of electrons, atoms, or functional groups.

Explanation:

Here are some class categories of these enzymes and their roles ;

• Oxidoreductases - Transfer of electrons (hydride ions or H atoms)

• Transferases - Group- transfer reactions

• Hydrolases - Hydrolysis reactions (transfer of functional groups to water)

• Lyases - Addition of groups to double bonds, or formation of double bonds by removal of groups Transfer of groups within molecules to yield isomeric forms

• Isomerases - Formation of C-C, C-S, C--0, and C-N bonds by condensation reactions coupled to ATP cleavage

The above are however classified, given code numbers, and assigned names according to the type of transfer reaction, the group donor, and the group acceptor.

Artyom0805 [142]

Answer:

The right matching of the scenario in the question are as follows:

1. OBSERVATION: Josh noticed that Julie ordered extra hot peppers and added hot sauce to her food  

2. QUESTION: Josh wondered how to cook spicy Mexican food.

3.  HYPOTHESIS: Josh decided jalapenos would be a good ingredient to add spice to the recipe.

4.  EXPERIMENT: After chopping the jalapenos, he slowly added some to the enchilada filling, tasting as he went until he thought it was spicy enough.  

5. RESULTS: Julie thought the enchiladas were delicious and exactly the right level of spice.  

6. CONCLUSION: Josh determined that since Julie liked the meal, adding jalapenos to the recipe was a good way to make it spicy.

Explanation:

Scientific method is an organized steps of procedures that scientists used to study and gather knowledge about different phenomenons. The systematic steps of scientific method start with observation, the observed phenomenon usually make a scientist to ask questions that he doesn't have an answer to. This will prompt him to formulate an hypothesis and set up an experiment to see if his hypothesis is true or not. The result he obtains from the experiment will determine the type of conclusion he will make about his earlier observation. By following these steps, scientists usually obtain useful  information that bring progress and advancement to humanity.

Why Do You Think Soil Erosion Increased Over Time ?
Firdavs [7]
Because Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away. Activities that remove vegetation, disturb the ground, or allow the ground to dry are activities that increase erosion.
