Make a table comparing and contrasting solids, liquids, and gases.
Please help
Answer:
I cant really do that but I will give u the material to make a table
Explanation:
Solid is the state of matter in which the substance has a definite shape and volume. Liquid is the state in which the substance takes the shape of its container but has a definite volume.Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy.

Explanation:
a scientific belief that was accepted centuries ago, but has since been disproved. How does it support the use of the term "scientific theory" instead of "scientific fact?"
Answer:
In the past was believed that species were fixed entities
Explanation:
Before Darwin's evolutionary theory (in which all living things arise through descendants with modification), Linnaeus had proposed that species were immutable entities. Although it was an erroneous concept, this belief enabled the development of a system for classifying and naming organisms. Indeed, Linnaeus is nowadays recognized as the father of taxonomy to create this system. This example shows that scientific knowledge is not based on factual information, but it is a process that progressively increases our understanding of the real world.

Which function do the stomata perform in photosynthesis?(1 point)
Answer:
They are pores surrounded by specialized parenchymatic cells, called guard cells. Stomata have two main functions, namely they allow for gas exchange acting as an entryway for carbon dioxide (CO2) and releasing the Oxygen (O2) that we breath. The other main function is regulating water movement through transpiration.
The stomata performs the function of absorbing and releasing gases in the process of photosynthesis.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

Nitrogen gas is more abundant in our atmosphere than oxygen! However, nitrogen needs to be converted into different forms to be used by many organisms. Bacteria are highly involved in this! Describe the role of (A) bacteria fixing nitrogen as they live symbiotically with some plant species, (B) nitrifying bacteria, and (C) denitrifying bacteria in the nitrogen cycle.
Explanation:
(A)role of nittogen fixing bacteria
=Nitrogen-fixing bacteria, microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle.
B)role of nitrifying bacteria
=Nitrifying bacteria convert the most reduced form of soil nitrogen, ammonia, into its most oxidized form, nitrate. In itself, this is important for soil ecosystem function, in controlling losses of soil nitrogen through leaching and denitrification of nitrate.
C)role of denitrifying bacteria
=Denitrifying bacteria converts nitrates back to nitrogen gas.
I WILL GIVE BRAINLIEST TO WHOEVER ANSWERS CORRECTLY FIRST . The image below depicts Earth's ozone levels from 2016. The darker portion indicates the lowest level of ozone.
Which of the following statements is true?
A. Thinning ozone levels in the atmosphere only affect the North Pole.
B. Thinning ozone levels in the atmosphere contribute to changes in bird migration patterns.
C. Thinning ozone levels in the atmosphere always accelerate the rate of photosynthesis in plant life.
D. Thinning ozone levels in the atmosphere may lead to increased exposure to ultraviolet radiation at the Earth's surface.
Answer:A
Explanation:
Ozone acts as a protective sheet above the earth's atmosphere which trap the hazard UV rays from sun. Therefore, the a depletion in the ozone layer causes increased exposure to UV radiation. Thus option D is correct.
What is ozone?Ozone is O₃, formed by the reaction of nascent oxygen with the atmospheric dioxygen. Chemically it is a toxic gas and highly reactive. An umbrella like layer of ozone gas is present in the stratosphere of the atmosphere.
This ozone layer protect us from ultraviolet radiation from sun. The UV rays are extremely dangerous which causes skin burn, head ache, respiratory and reproductive problems and even cancer.
Ozone is capable of trapping these uv rays without reaching to earth surface. Hence, a depletion in ozone layer increase the exposure to UV-rays.

imagine you are volunteering in a 1 st grade classroom. The students recently learned about the water cycle. One student raises her hand and asks, “I heard that elements like carbon can cycle too. How does carbon cycle? Is it like how water cycles?” How would you explain the cycling of carbon to this 1 st grade class? Keep in mind that the students have likely not taken an advanced science course yet!
Answer:
In carbon cycle, carbondioxide gas is present in the atmosphere. This carbondioxide gas is taken inside by the plant body through stomata and made food from it. When this food is eaten by animals, this carbon is transferred to their bodies. During breathing, carbondioxide gas is removed from animal body and the carbondioxide gas again goes to the atmosphere.
Explanation:
Answer:
The carbon cycle is similar to the water cycle!
Explanation:
The water cycle shows us that water on Earth isn't destroyed or created, it simply moves around in different forms. Carbon is like that too, but except becoming droplets and clouds it passes through stages where it can exist in the ground as things like coal and be burnt where it will then move into the atmosphere as a gas, until eventually that gas is used to grow a plant. Eventually, that plant will be eaten by an animal, and when that animal dies it goes into the ground once again. Hence, the carbon is always there, just going throughout the planet in different forms.

How does the attraction between the particles of a liquid relate to the
temperature at which the liquid changes state?
A. Weak attractions mean the liquid boils at a higher temperature.
B. Strong attractions mean the liquid freezes at a lower temperature.
C. Weak attractions mean the liquid freezes at a lower temperature.
D. Strong attractions mean the liquid boils at a lower temperature.
Answer:
C
Explanation:
C
The attraction between particles of liquid relating to the temperature at which liquid changes state are weak attractions meaning the liquid freezes at a lower temperature.
What is the relation between temperature and force of attraction?As the temperature increases of a liquid, the kinetic energy of the molecules increases to an extent where it can overcome the inter-molecular forces of attraction and as a result of which viscosity of liquid decreases and it can flow more easily.
When liquid changes state to solid at lower temperatures the forces of attraction are weakened to an extent to which state of matter changes from liquid to solid.During the process of transition from liquid to solid as temperature is lowered there is a decrease in viscosity of liquid .
