The correct matches are:
Birds - A
Dinosaurs - B
Amphibians - C
Corals - D
Trilobites - E
By the statements presented, we have the situation where the trilobites are the oldest of the species, thus they will be on the bottom layer. The corals are second ones that emerged, so they will be found in the second bottom layer, and after them come the amphibians that will be found in the third layer. The dinosaurs evolved after the amphibians, so since they are younger than them, they will be located in the second layer from the top, with the birds evolving from the later dinosaurs and being the youngest, they will be found in the top layer.
The answer is true! sorry if it's a bit late!!
Answer:
D
Explanation:
Double the first equation. Write the second below it. Rearrange the second.
2x - 20 = - 4y
<u>-2x -16= +4y</u> Add.
- 36 = 0
There is no solution to this pair of equations.
Answer:
Low Frequency, Long Wavelength, and Low Energy Transfer
Explanation:
Radio waves are on the larger(and lower frequency) side of the electromagnetic spectrum. These longer wavelengths mean that radio waves have a lower frequency because it takes longer for larger waves to travel. Therefore, less radio waves can travel a certain distance in a minute than a wave of a shorter wavelenght(and therefore lower frequency). Radio waves are considered a low-energy transfer wave. This is because they can be used in most environments for communication, air-traffic control, and broadcasting with little to no harm to the organisms around them. Even though radio waves can be found all around us, because they don't carry much energy, we aren't harmed by the radio waves.
