The cyanobacteria changed the composition of the earth’s atmosphere by evolving oxygen in what is referred to as the Great Oxygenation Event. This also allowed the ozone to be formed and block off most of the UV rays that are destructive to genetic material. Life was, therefore, also able to exist on land other than in water.
The right answer is A.
Lactic fermentation is a catabolic process, a fermentation, having as a starting point glycolysis, which produces an acid, lactic acid used to reoxidize NADH to NAD+, and by the way it produces energy in form of ATP.
In other words, lactic acid fermentation is a biological process by which sugars such as glucose, fructose, and sucrose are converted into cellular energy and metabolic byproduct, lactate. It is a lactic ferment that intervenes.
Answer: i would say the independent variable is the soil and the control variable is the seed because it stays the same in all of them to better understand the experiment while the dependent variable is the fertilizer.
Explanation: i am not completely sure but maybe someone else can also answer to verify it first
Answer:
The vision remains unaffected.
Explanation:
Rods and cones are two types of photo receptor cells present in the organism. Cone cell helps in the visualization of color whereas rod cells are involved in the light intensity.
The cat was stuck in the neighbor's cellar with enough food and water. The cat was stuck in the basement with pitch-black but this does not affect the vision of cat. Cats are nocturnal animals and has large amount of rod cells that enable them to see at night. Thus, her vision remains unaffected.
