1. Polymer refers to a lengthened, chain-like molecule comprising repeated units associated end to end.
2. Ceramic refers to a hard, brittle, corrosion and heat tolerant substance formed by administering a non-metallic mixture of minerals to intense heat.
3. Thermoset refers to the plastics, which exhibit low elongations and cannot get recycled again.
4. Thermoplastic refers to the plastics, which exhibit high elongations and can be recycled.
5. Crystal refers to the solid form originating from the organization of ions, atoms, or molecules in precise patterns of geometry.
6. Composite refers to a carbon fiber entrenched in a polymer resin matrix.
Answer:
Understanding the carbon cycle and how it behaves requires that we think of it as a complex dynamic system with components of the system interacting with each other in often unpredictable and emergent ways. A change in one part of a complex system can often cause a myriad of changes in other parts of the system. The Amazon forest ecosystem is a good example of a complex ecosystem currently undergoing changes.
Your teacher got this question from a website, serc.carleton.edu
Answer:
Anaerobic respiration
Explanation:
As rightly stated in this question, cells of all living organism synthesize ATP via the process of cellular respiration. Cellular respiration, however, occurs in stages starting with GLYCOLYSIS, which breaks down glucose to form PYRUVATE.
The metabolism of pyruvate in subsequent steps depends on whether the respiration process is occuring with or without oxygen. Without oxygen, pyruvate is metabolized in a process called ANAEROBIC RESPIRATION. Anaerobic respiration employs other molecules asides OXYGEN for last electron acceptor.
The statement that is true for asexual reproduction is :
D. Genetic information from a single parent is copied and passed on to form offspring with the same genetic information
The offspring that had different genetic information from its parents usually came from sexual reproduction , in which two parents contribute several different genetics
Answer:
A natural selection
D Plate techtonics
Explanation:
Movement of the plates over Earth’s surface is termed plate tectonics. Plates move at a rate of a few centimeters a year, about the same rate fingernails grow.
The idea that organisms can evolve by micro and macro evolution is a fact. However there is no definite factor to what produces evolution.
Natural Selection is a theory because it is backed by observable evidence but is not considered the definite cause as to why organisms can evolve due to surrounding debate
