Under normal temperature and pressure conditions, what type of rock could be formed from the weathering and erosion of metamorphic rock?
Sedimentary rock
The type of rock formed by the erosion and weathering of any type of rock is sedimentary rock. The smaller pieces broken off, or "sediments", come together to form the new, sedimentary rock.
The remora has a front dorsal fin that acts like a suction cup. It uses this fin to attach to whales, sharks, or rays and eat the scraps their hosts leave behind. What type of relationship is this?
It is an example of commensalism because the remora benefits from the food scraps while the shark, in this case, is neither helped or harmed.
If you put a straw into a glass of water, the straw looks to be bent, although nothing has really happened to the straw. The term that describes this property of light is
Refraction
What is the difference between repetition and replication?
Repetition is when you repeat the same thing (multiple trials)
Replication is when someone copies what the other did (doing someone else's experiment)
The crucial difference between relative dating and absolute dating is that
relative dating gives age compared to other nearby objects while absolute dating always gives a numerical age.
Suppose orange beetles and green beetles live in the same environment. Green beetles are harder to see on leaves, so birds eat primarily orange beetles. According to the theory of natural selection, in the future orange beetles will
decrease in population until they possibly become extinct.
According to the process of natural selection, since the birds are eating mainly orange beetles, the orange beetles will not be able to reproduce at the same rate as the green beetles, and they will decrease in population until they possibly become extinct.. Over time, there will be only green beetles as the birds eat the more visible, orange beetles.
Infrared, Visible light, Ultraviolet
What is the difference between scientific theories and scientific laws?
Scientific theories explain.
Scientific laws describe/tell.
What is the action force responsible for seafloor spreading?
The intrusion of magma forced up toward the ocean ridge.
Convection currents in the asthenosphere forces hot, less dense magma upward toward the crust. The action of the magma pushes apart the crust at the ridge and the magma fills in the gap that has been created as the sea floor spreads.
Which type of cell is created during meiosis?
Meiosis creates sperm cells and egg cells, which are also called gametes. Mitosis creates skin, liver, and blood cells, which are also called somatic cells.
Meiosis creates 4 different daughter cells. Mitosis creates 2 identical daughter cells.
Consider the Sun and Earth as a single system. How does the law of conservation of energy apply to this system?
All the energy that reaches Earth from the Sun was originally contained within the Sun’s atoms.
The law of conservation of energy tells us that energy can neither be created nor destroyed. The energy that reaches Earth from the Sun has to come from somewhere. All the energy that reaches Earth from the Sun was originally contained within the Sun’s atoms.
Distinguish the independent variable from the dependent variable.
The independent variable is the change the scientist does (the cause).
The dependent variable is what is being measured, or the results (the effect).
Explain what happen at each type of plate boundaries:
Convergent
Divergent
Transform
Convergent: Plates move towards each other.
1. ocean ocean- subduction, undersea volcano, volcanic island
2. ocean continent- subduction, ocean basin/ ocean trench, volcano
3. continent continent- mountains
Divergent: Plates move away from each other.
rift valley
midocean ridge
Transform: Plates slip past each other.
earthquake
During cell division, or mitosis, an exact duplicate of the original cell is produced. The instructions for cell division are found in the __________ in the __________.
chromosomes: nucleus
The instructions for cell division are found in the chromosomes in the nucleus Before a new cell is formed, the DNA in the chromosomes replicates, or makes a new copy. Then each new cell gets a copy.
Explain the 3 types of heat transfer.
Conduction- heat transfer through direct contact or touch.
Convection- Heat transfer through cycles. Hot air rises, cold air drops.
Radiation- heat transfer through electromagnetic waves.
Sara and Juan conducted an experiment to test which soil would be BEST for growing plants. They used sand, silt, and clay. They also made a mixture of soil using equal parts of sand, silt, and clay. They planted bean seeds in four pots and placed the pots in the sunlight. They watered the pots every day and tracked the seed germination and plant growth. At the end of the experiment, the seed in the pot of silt grew fastest.
Which conclusion can be drawn from the experiment?
Silt is the best type of soil for growing bean seeds.
During the rock cycle, ______________ follows erosion.
Deposition
Weathering breaks material into sediments. Erosion (takes it) carries the sediments. Deposition drops off the sediments. Cementation glues the sediments to form the sedimentary rock.
Magma and lava cools to form igneous rock.
Heat and pressure forms metamorphic rock.
This black dog has the genotype of BB for fur color. The black dog mates and has puppies with a solid white dog. The white dog has the genotype bb. What is the probability that this match will produce puppies that are also white?
0%. A dominant genotype, BB, crossed with the recessive, bb, produces offspring with the genotype Bb. Bb is also a genotype for black fur. Remember, black is dominant.
Based on the data in the table, what can we reasonably conclude about the speed of sound through various materials?
Material |speed of sound in m/s
air | 331
helium | 972
tap water | 1493
sea water |1533
aluminum | 5100
The speed of sound is higher in solids than in liquids.
The table suggest that the speed of sound is higher in solids than in liquids. Aluminum is the only solid and its speed of sound is significantly higher than the rest of them. Light travels faster in gases than solids.
