Answer:
The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others. Small molecules that are nonpolar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.

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.
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.

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

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.
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..

Suppose a dam was built that prevented melted snow from reaching streams and rivers below a series of mountains. How may this affect the water cycle?
Answer:
The water may not fall for a while because the water that dosen't go down the stream won't be able to evaporate. So rain clouds won't form in that area.

A solution of sodium iodide is added to a solution of potassium nitrate to make a potassium iodide precipitate and a sodium nitrate solution?
Key Words
KNO3
NaNO3
KI
NaI
Answer:
NaNO3
Explanation:
Sorry If its incorrect
The addition of a solution of sodium iodide and potassium nitrate has been the displacement reaction.
