Attractions between particles hold the particles of liquids and solids close together.
Why is the attraction that particles have for each other not enough to keep gas
particles close together?
Answer:
Kinetic energy is needed to overcome the force of attraction between particles of the same substance. In solids, particles don't have enough kinetic energy to overcome the force of attraction between them. The particles are packed closely together and cannot move around

Compare the particle model of light to the wave model of light
The wave model treats light as an electromagnetic wave. The particle model treat lights as if it were made of protons. The model could not explain the photoelectric effect, the color of hot objects, and the emission spectra.
What is the flow of the energy in the food chain?The flow of energy takes pace from producers → primary consumers→secondary consumers→ tertiary consumers. Primary consumers are the organisms that depends on producers for their energy needs. They are usually herbivores.
These organism lies at the second tropic level as the first level consists of producers. Some examples of primary consumers are rabbit, grasshopper, rats, et cetera.
Therefore, The wave model treats light as an electromagnetic wave. The particle model treat lights as if it were made of protons. The model could not explain the photoelectric effect, the color of hot objects, and the emission spectra.

Answer:
i would say negitive
Explanation: its a bad effect on life.
Answer:
Negative
Explanation:
The mutation that causes color blindness is negative for many reasons. First off, not being able to see color can cause you to not be able to do certain things in life. For example driving, if you can't see the correct colors to know when to stop or go, you can't safely drive. There are also some jobs where colors are important. Such as jobs that have to do with fixing colored wire. It's also bad because of how it takes away one of our senses and holds us back from seeing things and completeness. People who are colorblind can not truly experience the world like a person who can see color can.

How far does the sun’s corona extend into space?
A) 2,000 kilometers
B) 4,600 kilometers
C) 1.5 million kilometers
D) millions of kilometers
Answer:
D) millions of kilometers
Explanation:
The sun's corona extends million of kilometers into space from the sun outward.
The corona of the sun is one of the layers of the sun with blistering plasma extending into the space. It extends several million of kilometers away into the solar system. This layer has a whooping temperature of about 2-5million degree Celsius.
It is the light and energy conveyed through the corona that furnishes all the planets with radiant energy.
The following are sources of Earth's internal heat energy EXCEPT
a. Decay of radioactive isotopes
b. Primordial heat
c. pressure from overlying layers
d. Sun’s energy
The sun's energy is not a source of Earth's internal heat. So the correct option is D.
What is the earth's internal heat?
Nobody has even gotten close to directly examining the interior of the Earth. So there is disagreement among geophysicists as to how heated the Earth's core is. However, the speed at which earthquake waves, sometimes known as "seismic waves," move may reveal a lot to scientists about the composition of the Earth.
The solidity, liquidity, or partial solidity of these materials can also be determined using seismic data. Laboratory results, meanwhile, show what pressures and temperatures the materials inside the Earth should melt at.
The temperature of the Earth's core is thought to be between 5,000 and 7,000 degrees Celsius based on this information. That is far colder than the sun's inside, yet roughly as heated as the sun's surface.
Although the amount of heat created inside the Earth is immense, the amount of heat energy received from the sun is around 5,000 times stronger. The weather is influenced by the sun's heat, which ultimately leads to erosion. It is so paradoxical that although the heat of the Earth creates mountains, the energy of the sun gradually breaks them down again.
Therefore the correct option is D.

Which is a description of the Paleozoic era?
A. The rise of life
B. The age of the dinosaurs
C. The hottest era
D. The era of humans
Answer:
The rise of life
Explanation:
A.P.E.X.
A description of the Paleozoic era is A. The rise of life.
What is the Paleozoic era?The Paleozoic Era was a geological era that spanned from about 541 to 252 million years ago. It is often referred to as the "Age of Invertebrates" because it was during this time that the first major diversification of animal life occurred, and most of the animal life was invertebrates.
This era also saw the emergence of fish, amphibians, reptiles, and the first land plants. The Paleozoic Era ended with the largest mass extinction in Earth's history, known as the Permian-Triassic extinction event, which wiped out about 96% of marine species and 70% of terrestrial species.
The Paleozoic Era is a geologic era that began about 541 million years ago and lasted until about 252 million years ago. During this era, there were several major events that shaped the Earth's history and led to the evolution of new life forms:
During the early part of the Paleozoic Era, there was a sudden burst of new life forms, including many of the major groups of animals that we know today. This is known as the Cambrian explosion.
Therefore, A) Paleozoic era, is the correct answer.

Answer:
This question is incomplete but the completed question is below
The Nature Conservancy is an organization that protects a variety of habitats around the world. A project this organization would probably support is one that
(1) uses endangered animals for medical research
(2) protects the biodiversity of areas for future generations
(3) alters habitats for industry and housing
(4) prevents animal species from migrating to other habitats
The correct answer is (2)
Explanation:
Protecting habitats (which is the main "support" of this organization) will have to do with ensuring organisms live and are comfortable in the natural habitat they are found without or protected from "transgression" by humans and other possible biotic and even abiotic factors. Since, different organisms will normally live together in a community in order to "satisfy" the food chain and survive, this organization will most likely support projects involving the protection of biodiversity in different areas of communities of organisms for these organisms' future generations.
