Matter is defined by Lucretius as a primordial entity free of void and decay; they are the atoms that create entities. Atoms and primordial entities are synonymous with each other: the solidity of matter is called “procreant atoms, matter, seeds of things, or primal bodies, as primal to the world” (107-108). Lucretius uses all these words, emphasizing the simplicity of his philosophy. This simplicity is explained as he declares: “primal bodies are solid, without a void” (596). Because he believes that all entities are composed of primal bodies and a void, the primal body must be free of any void, thus giving substance to the object. He declares that entities are composed: “partly primal germs of things, and partly unions deriving from the primal germs” (566-567). This definition states that all matter consists of atoms, which, when combined, form molecules. Molecules, as defined by science, are the “unions” of atoms. This scientific principal is further explained: “So primal germs have solid singleness, which tightly packed and closely

5) List the three common states of matter in order of highest potential to lowest.

What is matter? Matter is the substance of which any physical object is composed of. Matter takes up space and has mass. Matter can actually undergo lots of changes either chemically or physically. During chemical changes, matter’s chemical composition changes. Bonds between atoms are broken and created to form new molecules! For an example, a rusting iron nail. When a iron nail is exposed to oxygen it transforms into rust, this ability to react is the chemical property/change. During physical changes, matter’s composition does not change. Something in the matter might seem or look different, but the atoms are still link up the same.

Matter is often defined as mass that can be physically observed by the senses, it can be measured scientifically and is tangible , it could be said the material world unlike aspects of social worlds is less abstract and easier to define, for example a building which comprises of bricks, wood, metal and other materials built into a specific shape compared to a community which can relate to people of the same place or shared values or interests or all. That is not to say that matter just is, it too can have agency and varying meanings dependent upon the

The message of the Millennium Ecosystem Assessment’s Governing Board is that human impacts on this resilient natural world are so unprecedented and extensive that we crossed the line into unsustainable consumption some time ago and are now depleting ecosystem capital stock instead of living off its sustainable goods and services.

The article discussed the changes in many habitats due to anthropogenic activity. Anthropogenic is an adjective that describes changes in nature due to the people. Next, this article discussed climate change and the impact that it is having on species like clams, and fish due to ocean temperatures rising. The article also addressed carbon dating of fossils to look for cause of extinctions. Human development and agriculture have had a tremendous impact on the population of many species that are terrestrial. Deforestation is a big problem that has caused a decline in the bird species. Commercial fishing in many areas has led to a decline in fish populations. Furthermore this article

2) When water freezes there are additional hydrogens bonds formed between molecules and those molecules become slow.

2. Fill in the blanks: Matter cannot be created or destroyed. Water, carbon, nitrogen, and oxygen must be recycled somehow in the environment, which also ensures that we do not use up or lose these essential materials.

What is the difference between a threatened species, an endangered species, and an extinct species?

is the genetic material of all organisms, it is the molecule of life and it

E) The number of bacteria would decrease due to a decrease in the temperature of the water.

The world warmed by about 0.7°C in the 20th century. Every year in this century has been warmer than all but one in the last century (1998). If carbon-dioxide levels were magically to stabilize where they are now (almost 390 parts per million, 40% more than before the industrial revolution) the world would probably warm by a further half a degree or so as the ocean, which is slow to change its temperature, caught up. But CO2 levels continue to rise. All this affect the ice pack in the Arctic. As temperature rises, ice melts. This causes many problems.

In aborginal languages, tho goana is called “bungarra”. In other central Australian language they are called “Tinka”. The specific name gouldi is latenised form of the name of the scientist who first described this species, English ornithologist John Gould.

States of matter are the distinct forms that different phases of matter take on. Historically, the distinction is made based on qualitative differences in bulk properties. Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter maintains a fixed volume but adapts to the shape of its container; and gas is the state in which matter expands to occupy whatever volume is available.

Matter is defined as anything that occupies space and can be perceived by one or more senses; a physical body, a physical substance, or the universe as a whole. There are four distinct states of matter: solids, liquids, gases, and plasma. There are other states of matter such as Bose-Einstein condensates and neutron degenerate matter, but those states can only be found under extreme conditions.
