what is a fossil fern providing evidence the continents once were joined (science)
Lets say a plant native to greenland is in canada (fossilized against canada's shore line) it's proof that at one moment they where actually connecting. <3
Animal remains (of one animal) found on two different continents.
please in the name of god help me guys.
1. D: the ability to cause a change or do work
The others dont make sense for energy.
2. C: Lamp
A lamp uses the electric current to light up a room, or area.
3. B: foil will bend away
The same charges repel each other that is why a magnet is repelled by the same pole of another magnet.
4. A: Sound
You can’t hear light or any of the other options.
5. A: gravity
Gravity is a force of nature that pulls on everything.
6. C: static electricity
The opposite charges stick to each other, a battery again is an example of this.
7. B: a copper nail
Metal is one of the best electric conductors.
8. C: closed circuit
This is because if a circuit is closed the electricity flows through perfectly but for example an open one would not work or it would leak energy.
Hope this helps
Students are planning an investigation into the distribution of charges in insulators and conductors. They know that charges can be transferred by conduction, induction, and friction. What materials and tests would they need to choose in order to identify conductors and insulators using conduction, induction, and friction?
A. Students need to choose metals and nonmetals. They would need to perform tests where materials are only touching non-charged objects, but not coming into the electric field of charged objects.
B. Students need to choose only metals. They would need to perform tests that include the touching of materials to charged objects, materials within the electric field range of
charged objects, and use some sort of force to cause friction to occur with materials.
C. Students need to choose metals and nonmetals. They would need to perform tests that include touching of materials to charged objects, materials within the electric field range of charged objects, and use some sort of force to cause friction to occur with materials.
D. Students need to choose only nonmetals. They would need to perform tests that include the touching of materials to charged objects, materials within the electric field range of charged objects, and use some sort of force to cause friction to occur on materials.
¨selective breeding should be more tightly restricted¨- do you agree or disagree with this statement and whyyyyyyyyyyyyy¨
Answer:
disa gree animals should be aloud to mate with another animal of the same breed freely
Explanation:
What two factors could the students change to investigate how to increase and decrease the magnetic force between the paperclip and the magnet?
A. Students could use a heavier retort stand and thicker string.
B. Students could change the color of the rock and the paperclip they are using.
C. Students could change the position of the clamp to move the magnet father away
from the paperclip.
D. Students could move the magnet further away from the paperclip and use a more
powerful magnet instead of a bar magnet.

what characteristic of a wave is related to the intensity of loudness of a sound?
1. Amplitude
2. Frequency
3. Wavelength
Th characteristic of a wave related to the intensity of loudness of a sound is amplitude. Amplitude is a measure of the intensity of waves.
What is amplitude of a wave ?Amplitude of a transverse wave is the height to the crest or trough from the base line. Amplitude of a wave is directly proportional to its frequency. Amplitude is measure of intensity of the wave.
Sound waves are longitudinal waves. Longitudinal waves are composed of compressions and rarefactions. The amplitude of a sound wave is the distance between the particles in compressions.
Amplitude is a frequency depended factor. As the frequency increases, amplitude of the wave also increases, making the wave energetic and sound louder. Hence, option 1 is correct.
Find more on amplitude:

To investigate absorption, Hector cuts two rectangles from five different-colored sheets of construction paper. He then staples three sides of each pair of rectangles to make a pocket and inserts a thermometer into each.
He takes the thermometers in the construction paper pockets outside, where it is clear and sunny. The initial temperature of each thermometer is 22°C. The image shows the thermometers after being outside for 15 minutes.
A thermometer in black paper reads 38 degrees Celsius, a thermometer in white paper reads 24 degrees Celsius, a thermometer in green paper reads 29 degrees Celsius, a thermometer in red paper reads 31 degrees Celsius, and a thermometer in blue paper reads 33 degrees Celsius.
Complete Hector's table by recording the final temperature and calculating the temperature change for each thermometer.
