What is an example of human movement? There are seven basic movements the human body can perform and all other exercises are merely variations of these seven: Pull, Push, Squat, Lunge, Hinge, Rotation and Gait. These motions focus on recruiting multiple muscle groups, making them efficient for those using time as an excuse not to […]
Is the presence of dissolved oxygen in water good or bad?
Is the presence of dissolved oxygen in water good or bad? Adequate dissolved oxygen is necessary for good water quality. As dissolved oxygen levels in water drop below 5.0 mg/l, aquatic life is put under stress. The lower the concentration, the greater the stress. Oxygen levels that remain below 1-2 mg/l for a few hours […]
What is the comparison between two numbers?
What is the comparison between two numbers? In math, to compare means to examine the differences between numbers, quantities or values to decide if it is greater than, smaller than or equal to another quantity. Here, for instance, we are comparing numbers. Why do we use comparison? Compare & Contrast acts as a practical and […]

How does removing a neutron change the mass?
How does removing a neutron change the mass? Neutrons do not carry an electrical charge so adding or removing them from the nucleus does not change the electrical charge of the nucleus. It does, however, change the mass of the nucleus. Adding or removing neutrons from the nucleus are how isotopes are created. Does Mercury […]
What is Heisenberg uncertainty principle describe it with example?
What is Heisenberg uncertainty principle describe it with example? The Heisenberg Uncertainty Principle states that it is impossible to determine simultaneously both the position and the velocity of a particle. The detection of an electron, for example, would be made by way of its interaction with photons of light. This reflected photon causes a change […]

Are beta rays harmful?
Are beta rays harmful? Beta particles are capable of penetrating the skin and causing radiation damage, such as skin burns. As with alpha emitters, beta emitters are most hazardous when they are inhaled or swallowed or absorbed into the blood stream through wounds. Gamma rays and X-rays: Gamma rays and X-rays are penetrating. How do […]
Is C-O more polar than Oh?
Is C-O more polar than Oh? Since ketones lack an OH, they are incapable of intermolecular hydrogen bonding. Another way to think about it is that there is a bigger electronegativity difference between O and H rather than between O and C, so the alcohol is more polar. Is C-CL more polar than CO? As […]
