Glucose is broken down in different ways both in the presence and in the absence of oxygen.Using the table for reference, which reaction precedes each member of the reaction set in column one?
Reaction set Preceded by
glycolysis A
Krebs cycle B
ETS C
lactic acid fermentation D


A.
A. photosynthesis in plants
B. glycolysis
C. glycolysis
D. Krebs cycle


B.
A. glycolysis
B. Krebs cycle
C. photosynthesis in plants
D. glycolysis


C.
A. glycolysis
B. Krebs cycle
C. glycolysis
D. Krebs cycle


D.
A. photosynthesis in plants
B. glycolysis
C. Krebs cycle
D. glycolysis

Answers

Answer 1
Answer: For the given reaction set:

Glycolysis (A) 
Krebs cycle (B) 
ETS (C) 
lactic acid fermentation (D)

Each of the elements of the reaction set is preceded by corresponding elements of set D which consists of:

A. photosynthesis in plants
B. glycolysis
C. Krebs cycle
D. glycolysis

To summarize the order of the reactions:

photosynthesis in plants > glycolysis > Kreb's cycle (aerobic respiration) or lactic acid fermentation (anaerobic respiration) > Electron Transport Chain (ETC)

Aerobic respiration: 
Photosynthesis produces glucose, which is used in glycolysis. Glycolysis produces ATP, NADH, and pyruvate. Pyruvate is then used in the Kreb's cycle to produce NADH, FADH2, ATP, and CO2. The ETC then uses the NADH and FADH2 to produce energy.

Anaerobic respiration:
The same process is followed until glycolysis. The pyruvate produced from glycolysis is used in the lactic acid fermentation process to produce lactic acid.
Answer 2
Answer:

Correct answer is

A. NAD+

B. ATP

C. Pyruvic Acid, ATP, NADH

D. ATP, FADH2, NADH

which ecoregion of Texas is most likely to be affected by wind erosion ?f. East Texas Piney Woods G. rolling plains H. Blackland prairies J .Gulf Coast prairies and marshes

Answers

Answer:

Option D. Gulf Coast Prairies and Marshes ecoregion

Explanation:

On the south east coast of texas, the Gulf Coast Prairies and Marshes ecoregion are located. The topography consists of plain flat land and the elevation is low. The soil type is mainly sandy and the vegetation near the coast is sparse. Thus, strong winds such as hurricanes and storm will carry away the  looses sandy soil and lead to beach erosion thereby destroying habitats for animals such as turtles, pelicans etc.

Hence, option D is correct.

Final answer:

The 'Rolling Plains' ecoregion of Texas is the most susceptible to wind erosion due to its grassland ecology and the nature of its sandy and loamy soils.

Explanation:

In the state of Texas, the ecoregion most likely to be affected by wind erosion would be the G. rolling plains. This area is predominantly comprised of grasslands, which lack the root structures and vegetation density of other regions like forests to hold the soil firmly in place. Therefore, they are more susceptible to the wind's forces. The sandy and loamy soils found in this ecoregion also contribute to vulnerability as they are lighter and more easily picked up by wind. Unlike these grasslands, regions like East Texas Piney Woods and Gulf Coast prairies and marshes have more vegetation coverage, minimizing the possibility of wind erosion.

Which carbohydrate provides energy for cows but only dietary fiber for humans?

Answers

Answer:

cellulose

Explanation:

cow eats grass mainly but not human.

Due to this reason, cow has cellulase enzyme that helps for digestion of grass which is not present i human.

So, cellulose is the carbohydrate present in cow bu absent in human.
