Erik remembered that his
science teacher had told him that an explosion in space could not really be heard. Why
is this so?

Answers

Answer:

Because space is a vacuum, gases released into space expand very quickly, and as they expand their density decreases. So say you were in a spaceship in the middle of a big space battle and a nearby ship exploded. The exploding ship would release gases and technically sound could travel along with them

. Compare: Compare the human and animal samples (human and mouse skin; human and worm neurons; human and fly muscle; human and frog blood). A. In general, are there any major differences that you can see? Explain.

Answers

Answer:

The epidermis which is the outermost layer of the skin vary when comparison is made between a human and animal skin.

Human skin has a thicker epidermis while Animals have a thinner epidermis.

The difference between human and insect muscles is that insect have mainly striated muscles which are primarily made of sarcomeres while animals have both the smooth and striated muscles.

The blood is different in humans and frog as humans red blood cells don’t have a nucleus while that of frogs have a nucleus in the red blood cells.

Human beings have very specific differences from other animals, due to their physical and biological constitution.

Based on this, we can answer the above question as follows:

Human skin and mouse skin are different in that human skin has seven layers, while mouse skin has between 10 to 20 layers.A worm has 302 neurons, while a human being has about 86 billion neurons.The fly has muscles adapted to flight, which allows these muscles to be rigid, resistant, and striated. On the other hand, human muscles are less rigid, are not adapted to flight, and can be smooth or striated.Human blood goes through a double circulation type and is of the complete type, while the frog's circulation is of the incomplete type, as it allows the mixture rich in oxygen with the blood rich in carbon dioxide.

Could you have identified any of the minerals after having described only a few, rather than all, of the properties you tested? If so, give an example.

Answers

Answer:

Unfortunately, you can rarely identify a mineral only by its color. Sometimes, different minerals are the same color. For example, you might find a mineral that is a gold color, and so think it is gold. But it might actually be pyrite, or “fool's gold,” which is made of iron and sulfide.
