list two of your favorite foods. Then, explain how the sun's energy helped make those foods available to you
puteri [66]
Pizza - The sun's energy helped make the pizza because the various ingredients required sunlight, either directly, or indirectly. For example, the cheese is made from cow's milk, and the cow's milk comes from a cow who eats grass (presumably), and the grass feeds off of the sun's energy through photosynthesis. Thus, the cheese is indirectly made with sunlight. Also, the grains used to create the flour used to make the dough used sunlight to grow. Finally, the tomato sauce is made from tomatoes, which are a plant that required sunlight to grow.

I only did one example, but I hope you can make another one with the information I provided yourself! Good luck. :)

harkovskaia [24]

Answer:

Perichondrium

Explanation:

Elastic cartilage (like hyaline cartilage) has chondrocytes located in lacunae and the tissue is surrounded by a perichondrium. The perichondrium (Figure 7–2) is a sheath of dense connective tissue that surrounds cartilage in most places, forming an interface between the cartilage and the tissues supported by the cartilage. The perichondrium harbors the blood supply serving the cartilage and a small neural component. Articular cartilage, which covers the ends of bones in movable joints and which erodes in the course of arthritic degeneration, lacks perichondrium.

Now suppose a stream has a high volume but a low gradient. How might the
Alecsey [184]

The stream has a high volume but a low gradient will run through small rocks and small valley. It slowly runs all over the area. Even though it is low gradient its volume is high so it craves the area and then it changes the land.

<u>Explanation:</u>

  • Low gradient streams are less forced but it is wider as it slowly flows through the land. As it is separated from the high gradient stream.
  • Then it finds its path and creates it. It will slowly eradicate the soil or land or rock which present in its path.
  • Day by day the flow of large quantity of water will change the position of the land.
  • Before reaching the sea, it will cover up the river.
