The U.S. is a leader in agriculture and food globally. In the last 150 years, technologies and innovations in the production, transportation, and retailing of food have developed economic growth at home and provided affordable food to the of people of the world.
What is the role of globalization in agriculture?Globalization has developed agricultural production and resulted it in growing much faster compared to the ones in the past.
Before the fast growth was around over 3 percent per year. Now at this time, it is 4 to 6 percent.
However, these increased rates of growth involve a particular change in its composition.
Thus, it can be concluded that globalization helped billions of people to overcome extreme poverty and improved their lives.

based on the data, what can you infer about the relative pH of the stomach?
The pH of stomach is important as it helps to induce the digestive enzyme called pepsin. The presence of HCL i.e., hydrochloric acids in stomach results in the pH of stomach to become acidic which range from 1.5 to 6.5 values.
What is the pH level of stomach?When the bolus enters the stomach, it aids the release of gastric juice having enzymes, mucous and HCL.
The upper and lower parts of stomach have varying pH values. Upper part has a pH of 4−6.5, while the lower part is with a pH of 1.5−4.0 which is highly acidic due to HCL.
Thus, the relative pH of stomach is acidic ranging from value 1.5 to 6.5.

which of the following organelles are found in plant cells but not animal cells
Answer:
The plant cells have cell wall, plastids, chloroplasts. These organelles are NOT present in animal cells.
Life system: cyanobacteria begin photosynthesis and produce oxygen. Earth system: free oxygen reacts with rocks (axidation), resulting in increased rates of weathering for soil
production. Life system: land plants evolve and take root in terrestrial soil.
O Life system: cyanobacteria begin photosynthesis and produce oxygen. Earth system: free oxygen reacts with all available dissolved iron in the ocean. Life system: mass extinction
event of anaerobic organisms occurs from buildup of oxygen in the ocean.
• Earth system: oxygen moves from the ocean to the atmosphere through gas exchange. Earth system: free oxygen reacts with incoming solar radiation to form ozone. Earth system:
ozone collects in the stratosphere to form the protective ozone layer.
O Earth system: molten Earth forms into layers based on density and pull of gravity. Earth system: Earth cooled, and the water vapor in the atmosphere condensed and created the
oceans. Life system: cyanobacteria evolved.
The cyanobacteria were already there without the oxygen, so that rules out A, and a lot of prokaryotes were anaerobic, so that rules out Finally, Photosynthesis does not require oxygen. Instead, Oxygen is a waste product of it.
What is photosynthesis?Photosynthesis is a process that occurs in the chloroplast organelle of plant cells. The typical light reaction of photosynthesis takes place inside the thylakoid membrane of the chloroplast. The chief reactants such as water and carbon dioxide participate in the reaction. The water gets oxidized in the reaction to release oxygen as a product. The carbon dioxide gets reduced.
Thus, Photosynthesis is a process that occurs in the chloroplast organelle of plant cells

Answer:
Not all the energy is passed from one level of the food chain to the next. About 90 per cent of energy may be lost as heat (released during respiration), through movement, or in materials that the consumer does not digest. The energy stored in undigested materials can be transferred to decomposers.

chromosomes from blood drawn from a five-day-old baby appears to have slight facial deformities and has been diagnosed with an atrial heart defect
Answer:
A congenital heart defect (CHD) is a heart problem that a baby has at birth. It is caused by abnormal formation of the heart during growth in the womb. In most cases, when a baby is born with a congenital heart defect, there is no known reason for it. Some types of congenital heart defects can be linked to an abnormality in the number of a baby’s chromosomes. They may be linked to single gene defects. Or they may be linked to environmental factors. In most cases, there is no clear cause that can be found for the heart defect. They are often thought to be caused by many factors. The factors are usually both genes and the environment. This means that genes from both parents plus unknown environmental factors lead to the problem.

How do geologists study direct evidence of Earth’s interior?
by collecting drill core samples of Earth’s crust
by measuring seismic wave activity
by analyzing how living things survive
by recording changes in climate patterns
Answer: A
Explanation: E2022
Geologists study direct evidence of Earth's interior by measuring seismic wave activity, which is the second option, as the seismic waves are waves of energy that travel through the earth's interior.
What are seismic waves?Geologists use various techniques to study the Earth's interior, but one of the most important is the measurement of seismic wave activity. Seismic waves are generated by various sources, such as earthquakes, volcanic eruptions, and human-made explosions. The waves travel through the earth's interior and can be detected by seismic instruments such as seismometers. Seismic waves come in two main types: body waves and surface waves. Body waves are waves that propagate through the earth's interior, while surface waves travel along the earth's surface. Body waves are further divided into two types: P-waves and S-waves.
Hence, geologists study direct evidence of Earth's interior by measuring seismic wave activity, which is the second option.

C. Most ingested food molecules are large.
D. To prevent disorders of the intestine.
1. Why is most food digested?
C. Most ingested food molecules are large.
Food is digested to break down big particles of food into smaller ones so that the absorption process takes place more efficiently.
Answer:

In one cubic meter of the ocean, photosynthetic plankton produce 80,000 calories of energy each year. How many calories of energy are available in the bodies of the creatures that eat that plankton?
Select one:
a.

b.

8000 calories of energy are available in the bodies of the creatures that eat that plankton. Details about calories can be found below.
How to calculate energy available?In a natural habitat, living organisms feed on one another to derive energy needed for their metabolic activities.
However, only 10% of energy available is transferred to the organism because 90% (most) of the energy is used for the organism's metabolism.
According to this question, in one cubic meter of the ocean, photosynthetic plankton produce 80,000 calories of energy each year.
Therefore, 10/100 × 80,000 calories = 8,000 calories of energy are available in the bodies of the creatures that eat that plankton.
