WHAT IS units in chemistry? Chemistry primarily uses five of the base units: the mole for amount, the kilogram for mass, the meter for length, the second for time, and the kelvin for temperature. The degree Celsius (oC) is also commonly used for temperature. What is the formula to convert kg to lbs? 1 Kilogram […]
Why are unit tests useless?
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 different stimuli?
What are the different stimuli? excited by three types of stimuli—mechanical, thermal, and chemical; some endings respond primarily to one type of stimulation, whereas other endings can detect all types. Chemical substances produced by the body that excite pain receptors include bradykinin, serotonin, and histamine. What are some examples of stimuli? Stimuli include: Irritants. Sights. […]
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 number is used in forced convection?
Which number is used in forced convection? The parameter of importance in forced convection is the Péclet number, which is the ratio of advection (movement by currents) and diffusion (movement from high to low concentrations) of heat. When the Peclet number is much greater than unity (1), advection dominates diffusion. What is the primary driving […]
What is the name of K+ ion?
What is the name of K+ ion? potassium Why is potassium K+? The name is derived from the english word potash. The chemical symbol K comes from kalium, the Mediaeval Latin for potash, which may have derived from the arabic word qali, meaning alkali. What is the symbol for beryllium? Be Is Potassium a negative […]
