Blank 2) ears
Eyes use light waves that are perceived on the retina and it then converted into electric potential in the optic nerve and sent to the brain to see.
Ears are funnels that transfer sound waves to the hammer and anvil and the mechanical energy is sent to the cochlea where hair cells move to sense sound.</span>
This question is incomplete. The question gives a choice between four skulls: A, B, C and D. The skulls are compared in a table for: Cranium/face area ratio, face angle and foramen magnum ratio.
The cranium/face area ratio relates to the size of the cranium relative to the rest of the skull, and we would expect this ratio to be fairly large for a human. The face angle relates to human faces in relation to primate faces, which are less protruded forwards (i.e., we have relatively flat faces), and the foramen magnum is the hole in the base of the skull through which the spinal column connects to the skull. In bipeds, we would expect this hole to be fairly equally distant from the back of the skull to the front of the skull, so this ratio would be closer to 1. Based on this information and the ratios given in the table, I would say that skull B is most likely a human skull.
I am sorry if this below does not help i tryed my best Most states east of the Mississippi River and the states of Missouri, Arkansas and Louisiana are located in the temperate rain forest biome, which is characterized by cold winters and warm, humid summers. Most of the Midwest is within the grasslands, which has a semi-arid climate with warm to hot summers.
Areas in and around the Rocky Mountains are in the alpine biome. Parts of California, Nevada and Arizona are in the desert biome. Oregon, Washington and southern Alaska are within the taiga biome, which features long, severe winters, and short, humid summers. Northern Alaska is a tundra, with long, dark winters that are especially cold. Hawaii is within the tropical rain forest biome, which is warm throughout the year with brief periods of reduced rain.
The combination of chemical reactions through which an organism builds up or breaks down materials is called metabolism. I believe.
