Aliyah found a tarnished silver dollar and recalled that tarnish results when metals react with oxygen or sulfur compounds in the air. She polished the silver dollar to remove the tarnish until it was shiny again. She also polished a copper bracelet and a gold ring. What physical property of these metals makes them shiny?

Answers

Answer 1

Answer:

LUSTER

Explanation:

Answer 2

The physical property of the metals that make them shiny is called Luster. Therefore, Aliyah was able to polish the metals like silver, copper, and gold.

What is luster?

Luster is one of the important physical properties of the metals, which refers to the way light is reflected from the surface of the metal. In the context of metal, luster refers to the shininess or brightness of the metal surface.

The luster of a metal ranges from dull to very shiny and can influence the perceived value of the metal as well as its suitability for various applications.

The luster of a metal can be affected by factors such as surface roughness, impurities, and exposure to environmental conditions such as corrosion and oxidation.

The treatment of a metal surface, such as polishing and plating, can also impact the luster of a metal.

General intelligence, commonly referred to as the “g factor,” is a wide mental capacity that affects how well on cognitive ability tests a person does. Thus, option B is correct.

What is general intelligence?

It is possible to describe general intelligence as a construct made up of various cognitive skills. These skills enable people to learn new things and resolve issues.

Underlying specialized mental talents in domains like verbal, spatial, numerical, mechanical, and mechanical abilities is this general mental capacity.

It is hypothesized that general intelligence influences how well people perform on all cognitive tasks.

You can relate general intellect to athletic ability. A person may be an exceptional runner, but this does not automatically make them a great figure skater.

Therefore, Dr. Ron supports the notion of general intelligence.

Water is essential for life. Its special properties make water the single most important molecule in plant life. Which of the following properties of water enables it to move from the roots to the leaves of plants?

Answers

Answer:

Because water exhibits cohesive behavior.

Explanation:

Cohesive behavior can be explained as a behavior where molecules are attracted to each other.

And this means that,  water molecules are attracted to each  other because of their cohesive behavior. This makes them to be  attracted to other substances, such as the walls of the xylem of plants.

In this case, it is believed that the water molecules behave this  way because they are polar, that is, there is an electronegativity difference between the bonded atoms. And this enables it to move from the roots to the leaves of the plants.

Various cultures designate racial categories differently, and they often base these categories on very different traits. For example, some cultures use nose shape as one of the defining traits for a racial group. Other cultures do not use nose shape in defining racial groups, but use hair color instead. Conduct a survey in person on your campus, via social media accounts online, or among your friends and family. Ask at least 20 people what five traits they think are most important when distinguishing racial groups. Document the responses, and then review the data. Did every person use the same traits? What do differences in racial classification such as these suggest about the universality of race and racial groupings?

Answers

Answer:

In the clarification segment below, the definition of the query has been mentioned.

Explanation:

This shows that perhaps the distinctions between individuals living in a culture or geographical region are often based on ethnicity and ethnic groupings. A single population belonging to a specific geographical region has been shown to possess many characteristics, including hair texture, individual capacity for heat resistance, and food taste. Throughout certain races or ethnic groups, these similar traits bring them together. The young government corresponding to a certain race is often asked to follow the custom adopted by those belonging to a certain particular demographic. It is assumed that persons belonging to that same race follow these rituals mostly to solve difficulties they have experienced personally due to errors perpetrated by certain ancestors.
