gasoline
natural gas
Answers
Answer:
Yes, the answer is wood.
Explanation:
Wood is a natural material and is subject to variations in composition and moisture content. Therefore the energy from burning it or gasifying it would likewise be variable.

why photosynthesis is known as the pathway for energy
Answers
Answer:
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die. It transforms light to chemical energy.
that's why it's called the pathway to energy.

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.

based on the data, what can you infer about the relative pH of the stomach?
Answers
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.

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
Answers
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.
