Answer:
Check down
Explanation:
Gymnosperms, like angiosperms (the flowering plants), differ from seedless plants (like mosses and ferns) in not requiring water for sperm to swim in to reach the egg. This means that the movement of pollen (male gamete) to ovule (female gamete) in seed plants relies on airborne transport, not water transport.
Answer:
The correct answer is option 1. "Amplitude".
Explanation:
Waves of sound have different properties, among them amplitude is the one that determines the loudness or volume of the sound. The amplitude is the height of the wave, measured in meters, or in other word the maximum displacement of the sound's particle from its position of equilibrium. If a dolphin calling sounds louder because of the background noise, the waves of the sound that the dolphin produces would have a higher amplitude.
His discoveries on the islands were paramount to the development of his Theory of Evolution by Natural Selection.
On the islands, Charles Darwin discovered several species of finches.
Thanks to his close observations, he discovered that the different species of finches varied from island to island.
Fossils can give information about past environmental conditions by showing the type of animal they belonged to. If a scientist found a whale fossil in a desert, he/she could assume that the desert was once an ocean as whales only live in oceans. If someone found a fossil of a lizard that inhabited trees, in the middle of the ocean, then he/she could assume that the ocean didn't exist at one point and instead, there might have been a forest in it's place.

The pipettes can basically be characterized into five grades. these grades includes the serological, disposable, repeat, single channel and multi-channel pipette. The guidelines for the usage of each of these pipettes differ. However, some instructions are common, such as the control of the flow of liquid. The index finger is used for the purpose of controlling the flow of the liquid from the pipette.
Hence, the answer is 'index finger'.
