What is the relationship between light intensity and gas production?
balandron [24]

Answer:

As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity. However, at sufficiently high levels of light intensity, the rate oxygen evolution remains constant.

What is mixed-acid fermentation? how is methyl red used to determine if a microbe has undergone mixed-acid fermentation?
Vika [28.1K]

Mixed Acid Fermentation is a biological process by which a six carbon sugar is converted into complex mixture of acids. It is an example of anaerobic fermentation reaction which is commonly seen in bacteria.

The fermentation produces lactate, acetate, succinate, formate, ethanol, H_{2} and CO_{2} and their formation depends upon the presence of certain key enzymes in the bacterium.

The Methyl Red test is used in detecting occurring of mixed acid fermentation pathway when glucose is provided to microbes by using ph indicator. If the fermentation pathway has taken place, the mixture of acids will make the solution very acidic and causes red color change. The Methyl Red test belongs to the group called as IMViC tests.

Identify and describe three chemical processes that weather rock
BartSMP [9]
These three (3) chemical reactions include Hydrolysis, Carbonation, and Oxidation. 

• Hydrolysis is a chemical reaction caused by the water in which water responds with the rock and changes the size and chemical arrangement of the minerals that reduces opposition to weathering. 

• Carbonation is an involvement of water with carbon dioxide to create carbonic acid. It appears when the rock minerals respond with fragile carbonic acid made when water associates with carbon dioxide in the air that deeds on the rock by breaching and disbanding the mineral substances. 

• Oxidation is recognized as rusting, a procedure whereby the rock minerals misplace one or more ions or atoms in the occurrence of oxygen. Once minerals in the rock rust it will develop less opposition to weathering. The oxygen associates with other constituents via oxidation method given that rise to ion or atom lose.
