Why are streak plates used the test minerals?

A. They show you the silicon content of the minerals
B. They show you the colors of the impurities in the mineral
C. They show you the true color of the minerals

Answers

Answer: c

Explanation: correct answer

Streak plates are used to test minerals because they show you the color of the mineral in powdered form. So, the correct option is C.

What are Streak plates?

Small pieces of unglazed glass or porcelain are known as streak plates, and they are used in mineralogy to assess the streak color of a mineral. They are usually a few inches in length and about an inch in width.

The streak of a mineral is its color after it has been ground into a fine powder and rubbed across a streak plate. Because some minerals have recognizable colors that differ from their actual color, it can be helpful to identify them.For example, hematite is a dark brown mineral with bright red streaks. You can differentiate hematite from other dark brown minerals by looking at the color of the streaks.

Therefore, the correct option is C.

Several factors were important for the extinction of mammoths to mastodons, and natural selection of the elephant, mainly the ecosystem they lived in and the search for food.

What are the differences between the mammoth and the elephant?

The mammoth is an animal that was once extinct and belonged to the genus Mammuthus and the family Elephantidae which included the proboscidians. Elephants differ from mammoths in that mammoths had their bodies covered with hair. Also, elephants are slightly smaller than mammoths.

What are the differences between the mastodon and the elephant?

Both were herbivores, but the mastodons had conical-shaped teeth designed to crush leaves and branches more easily. Mammoths had rough molars, allowing them to cut through vegetation and graze like modern elephants.

Whit this information, we can conclude that several factors were important for the extinction of mammoths to mastodons, and natural selection of the elephant, mainly the ecosystem they lived in and the search for food.

A space where water from various sources drains is called a watershed. The water from streams and rivers gets drained to a common outlet. The answer should be blank 1 factors, blank 2 human and blank 3 is food web.

What is a watershed?

A watershed is a section of drainage basin or "sheds" water into a particular body of water.

A watershed exists for every body of water. Rainfall and snowmelt are channeled into streams and rivers by watersheds.

These smaller bodies of water drain into larger bodies of water, such as lakes, bays, and oceans.

Abiotic and biotic factors enter and flow through the watershed. These can include plants, small microorganisms, soil, small rocks, and so on.

Human impacts have an impact on the food chain because activities such as deforestation, industrial emissions, and fuel combustion cause environmental changes that harm animals and plants in the ecosystem.

The food web depicts the energy flow in an ecosystem from producers to consumers and represents how energy is passed from plants to consumers as well as their interdependence.

Thus, it can be concluded that the blanks are factors, human and food web respectively.

c. glucose, energy

Answers

Answer:

C. glucose, energy

Explanation:

Glucose is ‘raw material’ in cellular respiration. It passes through the glycolysis cycle, in the cytoplasm of the cell. This occurs in virtually all cells. In eukaryotic cells, with mitochondria, the product of glycolysis (usually pyruvate) is channeled to the organelle and pass through the Citric acid /Krebs cycle that produces even more ATPs than glycolysis.

The degree to which chromatin is compacted greatly affects its accessibility for transcription, and thus, gene expression.

What is Transcription?

This is the process which involves copying a segment of DNA into RNA in organisms.

When chromatin is condensed, DNA becomes less accessible for transcription factors and vice versa which was why it was chosen as the most appropriate choice.
