Answer:
The correct option is<em> D) Models are not the "real thing" so it will never correctly represent the system in all respects.</em>
Explanation:
Scientific modelling can be described as a representation of the scientific theories or concepts in a way that can be better understood. Scientific models makes it easier to understand what physical, chemical or mechanical activity is taking place. Even mathematical representation comes under scientific modelling.
As models are not the real, hence they cannot be considered to be perfectly accurate. A model can never mark up to the complexity of nature.
Answer:
Amino acids are organic compounds that combine to form proteins. Amino acids and proteins are the building blocks of life. When proteins are digested or broken down, amino acids are left. The human body uses amino acids to make proteins to help the body: Break down food.
Answer:
Due to structure of engine.
Explanation:
Cars and trucks today powered by petroleum products because of their engine which only works when the petroleum products are used. When the petroleum products are burn in the engine, it produces small blasts which moves the piston and as a result the wheels of the car also start movement. Petroleum products are economically cheap due to its higher availability on the earth, easily available to the people, can be easily transported are the factors that make us use of petroleum products.
Answer:
The process occurring in Box A is Glycolysis
Explanation:
Glycolysis is the pathway by which glucose, a six-carbon molecule is oxidized to molecules of pyruvate, a three-carbon molecule with the release of ATP and electrons which are carried by NADH molecules.
The process occurs in the cytoplasm of cells and requires 10 glycolytic enzymes.
The pyruvate molecules from glycolysis is first oxidized to acetyl-CoA and carbon dioxide molecules. The acetyl-CoA molecules enter the citric acid cycle occurring in the mitochondria and are used up in the production of ATP, CO2, and electrons carried by NADH and FADH2.
The electrons carried by NADH and FADH2 from glycolysis and citric acid cycle are used in the oxidative phosphorylation pathway occurring inside the mitochondrion for transformation of oxygen molecules into water molecules with release of ATP.
C. cells . are the basic units of life
