What charge do humans have?

What charge do humans have? Resting cells are negatively charged on the inside, while the outside environment is more positively charged. This is due to a slight imbalance between positive and negative ions inside and outside the cell. Cells can achieve this charge separation by allowing charged ions to flow in and out through the […]

What comes first in trace conditioning?

What comes first in trace conditioning? a procedure in classical conditioning in which a conditioned stimulus and an unconditioned stimulus are separated by a constant interval (called the trace interval), with the conditioned stimulus presented first. What is the difference between forward conditioning and backward conditioning? Forward conditioning: Occurs when the neutral stimulus (NS) appears […]

Why is surface topography important?

Why is surface topography important? Surface topography refers to both the profile shape and the surface roughness (including the waviness and the asperity or the finish). Surface topography affects the film thickness to roughness ratio and the lubrication regime. These interactions become more important as the thickness-to-roughness ratio reduces. What is topography material? The topography […]

Why is Feb only 28 days?

Why is Feb only 28 days? This is because of simple mathematical fact: the sum of any even amount (12 months) of odd numbers will always equal an even number—and he wanted the total to be odd. So Numa chose February, a month that would be host to Roman rituals honoring the dead, as the […]

You will be able to provide in one platelet donation what would normally be collected from up to five whole blood donations. In fact, some platelet donations yield enough platelets for two […]

How do you know seafloor spreading?

How do you know seafloor spreading? Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. What is the oldest seafloor? […]
