Answer: The simplest way is to determine if a strain is mutant is observing morphology, growth rate, double time, etc but it is accurate if you can prove if the strain is deficient in one aminoacid or can't metabolize lactose, etc.
Explanation: A wildtype strain functions normally, for example, can metabolize as a carbon source, glucose, lactose and other sugars, can synthesize all the aminoacids requered for protein synthesis, etc. If a strain suffers a mutation and it is inheritable, the strain become a mutant. Since several mutations can be silent ones, only those that interfere with a process, can be assesed easyly.
For example, if you have several strains and put them in a lactose medium, but some of them cannot growth means that are lactose mutants. Those strains could carry a mutation in genes that encode lactose degrading enzymes or in regulatory genes of the lac operon, etc.
Moraines are made of till. They form when a glacier stays in one place for a long time and deposits a pile of till, then it retreats and leaves a moraine.
There was no life on Earth for the first billion years because the atmosphere was not suitable for life. Earth's first atmosphere had lots of water vapor but had almost no oxygen. Later, frequent volcanic eruptions put several different gases into the air.
Answer:
The correct answer is - Physics
Explanation:
Physics is the branch of science that is an organized study of matter, motion, light, energy, and its behavior in time and space. All these states in the observable universe and their effect is studied in detail in physics.
Physics is one of the basic and fundamental disciplines of science like biology, chemistry. Many other streams or filed of science are based on physics such as chemistry, oceanography, seismology, and astronomy.
Thus, the correct answer is - Physics
