Why are unit tests useless? Unit tests ossify the internal structure of the code. All the unit tests are suddenly rendered useless. Some test code may be reused but all in all the entire test suite has to be rewritten. This means that unit tests increase maintenance liabilities because they are less resilient against code […]
What happens if the brain does not maintain homeostasis?
What happens if the brain does not maintain homeostasis? What happens if there’s disruption? If homeostasis is disrupted, it must be controlled or a disease/disorder may result. Your body systems work together to maintain balance. If that balance is shifted or disrupted and homeostasis is not maintained, the results may not allow normal functioning of […]
What are the four principles of stratigraphy?
What are the four principles of stratigraphy? Steno’s laws of stratigraphy describe the patterns in which rock layers are deposited. The four laws are the law of superposition, law of original horizontality, law of cross-cutting relationships, and law of lateral continuity. Nicolaus Steno was a 17th-century Danish geologist. Which kind of unconformity is probably the […]
What are the three roles of bacteria?
What are the three roles of bacteria? In summary, bacteria are single-celled microbes without a nucleus. Bacteria play many roles in our ecosystem. Bacteria are decomposers which break down dead material and recycle it. They also can be producers, making food from sunlight, such as photosynthetic bacteria, or chemicals, such as chemosynthetic bacteria. What are […]
Does the Earth accelerate towards you?
Does the Earth accelerate towards you? Earth accelerates towards you So the mass of the Earth relative to you is incredibly large. From Newton’s second law of motion we know that for a given force on an object the acceleration reduces as the mass of the object increases. However the Earth still accelerates towards you […]
Can I lock my bike to a street sign?
Can I lock my bike to a street sign? Street signs are placed in the right of way. So even if it’s on someone’s private property, it’s still public (government) property. You pay taxes, you vote… use the sign as long as you don’t deface, damage, or otherwise obscure it’s message, you should be good. […]
What is an investigation that is controlled?
What is an investigation that is controlled? A controlled experiment is a scientific test that is directly manipulated by a scientist, in order to test a single variable at a time. This group is referred to as the control group, and allows for comparison with the other group, known as the experimental group. What are […]
Which organ system is responsible for obtaining oxygen?
Which organ system is responsible for obtaining oxygen? The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. It consists of the nose, larynx, trachea, diaphragm, bronchi, and lungs. How […]
Which best explains why one laser beam might appear?
Which best explains why one laser beam might appear? Answer: One laser beam might appear blue and another laser beam might appear red because each laser beam is made up of one specific wavelength of light. Explanation : This means that laser light emits light of single frequency or wavelength. That’s why one laser beam […]
