Answer:

Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.

Cells have an organelle known as 'mitochondria' which has ATP molecules in it. These ATP molecules generates energy for the cell to function properly.

Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy.

This process is called 'cellular respiration'.

The process is happens in all the cells in our body.

Oxygen is used to oxidize food, main oxidized food is sugar(glucose).

Green
Red
Blue

The term Green Revolution, a movement that was initiated by agronomist Norman Bourlag, is used today to identify the increase in food production of agricultural origin, starting in 1960.

the strategies that led to the increase in agricultural production and food availability that characterized this revolution were:

Planting and cultivation of products resistant to pests and climatic changes, such as rice, wheat and corn.
The introduction of machinery and instruments to facilitate crops.
The design of efficient irrigation systems.
The use of chemical products to favor agricultural activity, such as fertilizers and pesticides.

The Green Revolution began in the United States, and its success allowed other countries to adopt its techniques.

What indication is shown when Benedict's solution changing from blue to orange when heated?. . A. the presence of reducing sugar

svlad2 [7]

Benedict's solution is used in the laboratory experiments to detect the presence of reducing sugars or monosaccharides in a sample. Benedict reagent's colour change from blue to orange indicates that the test is positive confirms the presence of reducing sugars. One very important example of the use of Benedict's solution is in the diagnosis of Diabetes by detection of the presence of reducing sugars in a urine sample.

What macromolecules in the plasma membrane are most directly responsible for transporting large.

andre [41]

Answer:

Proteins

Explanation:

There are proteins in the membrane that have channels for large polar molecules to move into or out of the cell since the plasma membrane is made of a phospholipid bilayer where the inside is non polar. This means large polar molecules need help from proteins to cross the plasma membrane.
