Answer:
pyroclastic flow is a fast moving current of hot gas and volcanic matter that flows along the ground away from a volcano at high velocities.
Hotspot is volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle
caldera-a large volcanic crater, especially one formed by a major eruption leading to the collapse of the mouth of the volcano.
tephra-rock fragments and particles ejected by a volcanic eruption
epicenter-the central point of something, typically a difficult or unpleasant situation
fault-an extended break in a body of rock, marked by the relative displacement and discontinuity of strata on either side of a particular surface
surface waves- mechanical wave that propagates along the interface between differing media
body waves-A body wave is a seismic wave that moves through the interior of the earth, as opposed to surface waves that travel near the earth's surface. P and S waves are body waves.
sorry if this doesnt help
Answer:
sieve-tube elements, companion cells
Explanation:
Sieve-tube elements and companion cells are responsible for the movement of photosynthes through a plant.
The sieve tube elements are shorter (almost organelle-free) living cells, placed end to end, forming the sieve tubes. Their transverse cell walls are called sieve plaques that make connections between cells and through openings called sieves establish the connection between the cytoplasm of adjacent cells. Each sieve is coated with calose (glucose polymer), which in winter can completely clog the vessel and then dissolve in spring. When infections occur or the vessel is parasitized, it can also be clogged with callose.
Companion cells are specialized parenchymal cells, which contain all the components that exist in living cells, including the nucleus, are the cells most closely linked to the sieved tube element. The Screened Tube Element and its companion cells are related in development, are derived from the same mother cell, and have several cytoplasmic connections to each other. Due to the many connections, the potential function of the companion cells is to release substances into the sieved tube element and, when the nucleus is absent, to include information molecules, proteins and ATP. When a screened element dies, its companion cells also die, which is a demonstration of this interdependence.
Which combination of characteristics in a population would provide the greatest potential for evolutionary change?
a. large population, few mutations
b. small population, many mutations
c. small population, few mutations
Small population, many mutations are the combination of characteristics in a population would provide the greatest potential for evolutionary change.
b. small population, many mutations
<u>Explanation:</u>
Stabilizing selection in development is a kind of common choice that supports the normal people in a populace. In little, reproductively detached populaces, extraordinary conditions exist that can create fast changes in quality frequencies absolutely autonomous of transformation and normal determination.
Natural Selection prompts a transformation change when a few people with specific qualities in a populace have higher endurance and regenerative rate than others and give these inheritable hereditary highlights to their posterity. The power of Natural Selection aside, populace size is as yet a factor to be considered.
Seed plants have an evolutionary advantage for several reasons. For one, the seeds can disperse easily. Furthermore, seeds can time their germination. For example, some seeds only germinate when they experience a period of being frozen.
