How is an image formed by a plane mirror?
A) Light bounces off of the mirror and then appears to come from in front of the mirror.
B) Light passes through the mirror and then appears to come from behind the mirror.
C) Light passes through the mirror and then appears to come from in front of the mirror.
D) Light bounces off of the mirror and then appears to come from behind the mirror.

Answers

Answer:Light bounces off of the mirror and then appears to come from behind the mirror.

Explanation:Plane mirrors form images that are virtual, upright and the same size and shape as the object it is reflecting.

When rays of light from the object hits a plane mirror they bounces off the mirror,that is they undergo reflection, and appear to originate from behind the mirror, resulting to the formation of a virtual image.

The image formed appears to be behind the plane in which the mirror lies. A virtual image is an image that is formed at a location from which the rays of light appear to come from. The image can not be formed on a screen..

B - Let’s say for example you put 2 penguins onto Antarctica and then you put 2 giraffes onto the same place. Giraffes have very soft skin and can’t tolerate the cold and basically need warmth to live. They also cannot get their primary food source which are leaves, the environment matters a lot and the penguins would flourish as they would be made for fishing in the ice cold water.

Alfred Wegener proposed the theory of continental drift around 1912. Which of these components of his theory is now known to be FALSE?
Select one:

a. Similar plants and animals live on continents separated by oceans.

b. All existing continents were once joined into a supercontinent.

c. The boundaries of many neighboring continents fit together.

d. The Moon’s gravity and Earth’s spin can move the continents.

Answers

It should be D because
- A is true. There are fossils that have been found in in different places but separated by oceans
- B is true because of Pangea
- C is true because Pangea was broken into chunks that make up our earth today

The component of Alfred Wegener's theory that is known to be false is as follows:

The Moon’s gravity and Earth’s spin can move the continents.

Thus, the correct option for this question is D.

What is continental drift?

Continental drift may be defined as the process of the gradual movement of continents as the result of the motion of tectonic plates. It is a type of hypothesis that illustrates that the Earth's continents have migrated over geologic time with respect to each other.

This theory by Alfred Wegener demonstrates that similar kinds of plants and animals live on continents separated by oceans. According to him, all existing continents were once joined into a supercontinent known as Pangea. The boundaries of many neighboring continents fit together due to the gradual splitting of Pangea.

Therefore, the Moon’s gravity and Earth’s spin can move the continents is the component of Alfred Wegener's theory that is known to be false. Thus, the correct option for this question is D.

Answers

Answer:

NaNO3

Explanation:

Sorry If its incorrect

The addition of a solution of sodium iodide and potassium nitrate has been the displacement reaction.

The reaction has resulted in the formation of the precipitate of Potassium iodide and Sodium nitrate.

The chemical equation for the reaction can be:

[tex]\rm NaI\;+\;KNO_3\;\rightarrow\;NaNO_3\;+\;KI[/tex]

The reaction has been an exothermic reaction with the formation of the pale yellow precipitate of the potassium iodide.

Out of all the planets in the solar system, Earth is the only planet that scientists can study in detail. Atmospheric scientists can measure minute by minute atmospheric conditions (weather) from ground level to the “edge of space” by use of surface instruments and space vehicles. Geologists not only can detail surface features and how they change over time, but also can deduce Earth's structure to its very center. The division of Earth's interior into a core, mantle, and crust structure sets the context for how we study the other similar planets.

Describe how sound waves travel through a solid, liquid, and gas. Why does it move differently through these different mediums?

Answers

Answer:

Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster. Sound travels most slowly through gases because the molecules of a gas are farthest apart.

Other Causes of Extinction

In addition to habitat destruction, other human-caused problems are also threatening many species. These include issues associated with climate change, pollution, and over-population.

Climax Community

A climax community is the end result of ecological succession. The climax community is a stable balance of all organisms in an ecosystem, and will remain stable unless a disaster strikes.

Invasive Species

As we have learned earlier in the unit, invasive or non-native species can also change an ecosystem.

When invasive species enter an ecosystem they change that ecosystem's dynamic and cause a disruption to the flow.

Habitat Destruction

Your habitat can be altered, and you can easily adapt. Most people live in a few different places and go to a number of different schools throughout their life. But a plant or animal may not be able to adapt to a changed habitat.

Humans often destroy the habitats of other organisms. Habitat destruction can cause the extinction of species.

Extinction is the complete disappearance of a species. Once a species is extinct, it can never recover.

Human Activity

It's important to note that human activity has the greatest impact on the amount and quality of wildlife habitat in many areas of the world. Wildlife habitat can be destroyed or its quality diminished as a result of urban growth, agricultural practices, pollution, or habitat destruction.

People can also have a positive impact on wildlife populations through improvement and protection of habitat or ecosystems. Planting trees and shrubs and providing sources of food and water in individual yards is one way people can help wildlife.
