Answer:
D. If an earthworm is given a choice, it will move toward darkness rather than light.
Explanation:
A hypothesis must be a declarative statement that can be tested. That is the only one that follows the guidelines for a good hypothesis.
Weathering and erosion are similar in that they both work together to change and shape the Earth's surface. While weathering breaks rock and earth down, erosion is the displacement of the pieces and particles of rock and earth.
These three species are distantly related and share a common ancestor
The correct answer is A - leaves that close when touched.
The Venus flytrap is a type of flowering plant that is best known for its unique adaptation to trap live insects using a trap.
The trap is made up of two hinged lobes at the end of each leaf, with hair like projections called trichomes that cause the lobes to snap shut when prey comes into contact with them.
This type of movement is called thigmonasty which is a non directional plant response to being touched.
1. Evaporation is the escape of water molecules from their liquid phase to gas phase that go up into the atmosphere. Evaporation can occur anywhere where open liquid water is exposed to sunlight or any other source of energy. Transpiration, on the other hand, is the loss of water (by evaporation) from plants through the stomata. Evaporation and transpiration move water from the biosphere to the atmosphere.
2. Condensation is the return of water molecules from gaseous phase (vapor) back to liquid form. Precipitation, on the other hand, is the coming down of condensed water from the atmosphere to the earth (biosphere), which is a significant part of the water cycle.
3. Exchange pool is the pool from (or approximate amount) which water or other elements are shared (back and forth) between different spheres (such as biosphere, atmosphere, and hydrosphere) in a cycle. A reservoir on the other hand is analogous to a ‘container’ that holds large masses of water or other elements such as a lake and the atmosphere.
4. The answer is No. because, today’s waters, due to increased pollution from industrialization that spews a lot of pullutans into the atmphere, ae contamiated. The water that precipitates is tainted by gases such as sulphuric dioxide tha makes it acidic. The water also gets polluted by other pollutants in the atmpshre and biosphere and hence become a health risk to animals and humans that drink it.
