Answer:
In anaerobic respiration, one molecule of glucose is broken down into two molecules of ethanol (in yeast) or lactic acid (in muscle cells) with a net gain of two molecules of ATP (adenosine triphosphate).
Two molecules of carbon dioxide are released as the byproduct.
It helps in regenerating the NAD⁺ lost in the process of glycolysis.
The overall process is termed as fermentation.
Lactic acid fermentation is catalyzed by the enzyme lactate dehydrogenase and alcohol (ethanol) fermentation is a two-step process which is catalyzed by pyruvate decarboxylase and alcohol dehydrogenase.
Answer:
Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
Hope it helped u if yes mark me BRAINLIEST!
Tysm!
Answer:
breathing allows the exchange between 2 gases: oxygen and carbon dioxide. Gas exchange occurs in millions of lung alveoli and the capillaries that surround them
Explanation:
B. sand – silt – clay
C. silt – sand – clay
D. silt – clay – sand
The size of the sediments from the smallest to the largest is clay followed by silt and then sand.
It refers to the relative particle size composition of the soil. In the soil, the particle size composition refers to the percentage of the mineral matter by weight in each fraction. On the basis of the International Society of the Soil Science, the size of the various types of soils are:
Thus, the correct order of sediment size from smallest to largest will be clay-silt-sand.

clay - silt - sand the answer is correct I took the test and sand-silt-clay is wrong
B) evolution and human development
C) how the physical world functions
D) the possibility of time travel
Answer:
The correct answer is option C, how the physical world functions
Explanation:
Einstein theories were quite fascinating and revealed some concepts which have changed the way science was studied. For example the theory of relativity explained the behavior of an object in space and time (concept of four dimensional). His theory of relativity introduced the “absolute” frame of reference according to which whenever some quantity is measured be it velocity, momentum etc. it is in reference to some thing.
This absolute reference do not apply to the speed of light and also nothing is faster than the speed of light. Like wise his theories changed the perception of scientist/scholars with respect to the existing scientific theories as well as the future theories to be discovered.
