Answer:
Explanation:
Actually it was the experimental results of other scientists. The main stems of the theory was the indivisibility of small spheres (his image) that represented the elements he knew which reacted with other elements.
They seemed to give the same ratios in reactions (definite proportions) and multiple whole number ratios. Look up Lavoisier.
Answer:
People giving antibiotics to food animals are required to follow a "withdrawal time" after treatment. The withdrawal time is a waiting period after treatment that gives the animal time to reduce the concentration of the drug in its body, and therefore in the meat (or milk or eggs) the animal produces.
Answer:Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. ... On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes.
Explanation:
Answer:
Ecological succession happens when new life takes over an environment. ... Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment
Ecological restoration aims to recreate, initiate, or accelerate the recovery of an ecosystem that has been disturbed. Disturbances are environmental changes that alter ecosystem structure and function. Common disturbances include logging, damming rivers, intense grazing, hurricanes, floods, and fire
Secondary succession is usually faster than primary succession because soil and nutrients are already present due to 'normalization' by previous pioneer species, and because roots, seeds and other biotic organisms may still be present within the substrate
