Explanation:

Answer:

matter into oil. (Another word for this kind of oil is petroleum.) Given enough pressure, organic matter can also become natural gas. Heat and pressure are the two main forces that transform organic matter into fossil fuels.

Explanation:

Petroleum is used to make gasoline, an important product in our everyday lives. It is also processed and part of thousands of different items, including tires, refrigerators, life jackets, and anesthetics.

The geological conditions that would eventually create petroleum formed millions of years ago, when plants, algae, and plankton drifted in oceans and shallow seas. These organisms sank to the seafloor at the end of their life cycle. Over time, they were buried and crushed under millions of tons of sediment and even more layers of plant debris. With more heat, time, and pressure, the kerogen underwent a process called catagenesis, and transformed into hydrocarbons. Hydrocarbons are simply chemicals made up of hydrogen and carbon. Different combinations of heat and pressure can create different forms of hydrocarbons. Some other examples are coal, peat, and natural gas.

Oil comes in the category of petroleum and matter into the oil. Given enough pressure, organic matter can also become natural gas. Heat and pressure are the two main forces that transform organic matter into fossil fuels.

A fossil fuel has been  hydrogen containing material found naturally in the earth's crust from the remaining portion of dead plants and animals that has to be extracted and burned as a fuel.

Fossil are natural source of energy, it has been made from decomposition of the plants and animals. Fossil fuels has been found in earth's crust and contains carbon and hydrogen which could gives energy while burning. Natural gas usually found in pockets above oil deposits. It has also found where natural oil has to be found.

Coal, oil and natural gas are best examples of fossil fuels. Coal has a material usually found in sedimentary rock deposits where rock and plants has to be buried from long time. Oil has originally found as a solid material between layers of sedimentary rocks, like shale. This material has heated and converted into a gasoline.

Therefore, Oil comes in the category of petroleum and matter into the oil. Given enough pressure, organic matter can also become natural gas. Heat and pressure are the two main forces that transform organic matter into fossil fuels.

Answer:

I will!

Explanation:

to determine the related age of different rocks geologists start with the assumption that unless something has happened in the sequence of sedimentary rock layers the newer Rock layers will be on top of the older ones this is called the rule of superposition with absolute age dating you get a real age and actual years

Answer:

Geologic time uses the layers of rock to describe the relationships of events and their sequence in chronological order over the history of Earth. The layering is a result of the buildup of tiny bits of rock, sediment, or lava cooling at the surface over many years. Think of it like a stack of pancakes—the bottom layer is the one that was placed first and therefore is the oldest. The sediments that create the layers of Earth are stacked one on top of the other.

Answer:

Explanation:

A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.[1] These collisions happen on scales of millions to tens of millions of years and can lead to volcanism, earthquakes, orogenesis, destruction of lithosphere, and deformation. Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types.

Plate tectonics is driven by convection cells in the mantle. Convection cells are the result of heat generated by radioactive decay of elements in the mantle escaping to the surface and the return of cool materials from the surface to the mantle.[2] These convection cells bring hot mantle material to the surface along spreading centers creating new crust. As this new crust is pushed away from the spreading center by the formation of newer crust, it cools, thins, and becomes denser. Subduction begins when this dense crust converges with less dense crust. The force of gravity helps drive the subducting slab into the mantle.[3] As the relatively cool subducting slab sinks deeper into the mantle, it is heated, causing hydrous minerals to break down. This releases water into the hotter asthenosphere, which leads to partial melting of asthenosphere and volcanism. Both dehydration and partial melting occurs along the 1,000 °C (1,830 °F) isotherm, generally at depths of 65 to 130 km (40 to 81 mi).[4][5]

Some lithospheric plates consist of both continental and oceanic lithosphere. In some instances, initial convergence with another plate will destroy oceanic lithosphere, leading to convergence of two continental plates. Neither continental plate will subduct. It is likely that the plate may break along the boundary of continental and oceanic crust. Seismic tomography reveals pieces of lithosphere that have broken off during convergence

Explanation:

Chloroplasts are organelles that conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water in plant and algal cells. 

A chloroplast is an organelle inside the cells of plants and certain green growth that is the site of photosynthesis.

Chloroplasts permit plants to catch the energy of the Sun in energy-rich atoms. The cell dividers permit plants to have unbending designs as fluctuated as wood trunks and flexible leaves, and vacuoles permit plant cells to change size.

Explanation:

As Earth cooled, an atmosphere formed mainly from gases spewed from volcanoes. It included hydrogen sulfide, methane, and ten to 200 times as much carbon dioxide as today's atmosphere. After about half a billion years, Earth's surface cooled and solidified enough for water to collect on it.

Oxygen plays a critical role in respiration, the energy-producing chemistry that drives the metabolisms of most living things. We humans, along with many other creatures, need oxygen in the air we breathe to stay alive. Oxygen is generated during photosynthesis by plants and many types of microbes.

Answer:

Ocean currents bring nutrient-rich water into coastal regions.

Explanation:

About 70 percent of our planet is covered by water. The earth has been declared a "blue planet" because it looks blue from space. About 96 percent of this water is the sea or salt water, made up of the ocean that covers the Earth.

Within these oceans, there are many different types of habitats or environments inhabited by plants and animals, from the freezing of polar ice to tropical coral reefs. Most marine life is found in coastal habitats.

Carbohydrates.

Explanation:

It is carbohydrates because they are the good source of energy . When carbohydrates are consumed it's digestion starts from the mouth, from chewing and it mixes with saliva from the salivary gland. As it is broken down the chemical energy unlock in it is released into the body which is absorbed by the cells for cellular metabolic activities. They turns into energy as soon as they are ingested and they energy powers the brain and the whole body.

Examples of carbohydrates are wheat, whole grains, rice, bread e.t.c.

Answer:

DNA technology is very beneficial in the criminal and civil justice system, methods such as fingerprinting are used very often when trying to find a person behind a crime. This technology has also improved our use of medicine. One way is breeding plants to create more options of curing diseases by using adding nutrients and minerals. Lastly, DNA is used to grow crops that have a lot more nutrients and minerals that are added from other plants.

Explanation:

Characterization, or ''typing," of deoxyribonucleic acid (DNA) for purposes of criminal investigation can be thought of as an extension of the forensic typing of blood that has been common for more than 50 years; it is actually an extension from the typing of proteins that are coded for by DNA to the typing of DNA itself. Genetically determined variation in proteins is the basis of blood groups, tissue types, and serum protein types. Developments in molecular genetics have made it possible to study the person-to-person differences in parts of DNA that are not involved in coding for proteins, and it is primarily these differences that are used in forensic applications of DNA typing to personal identification. DNA typing can be a powerful adjunct to forensic science. The method was first used in casework in 1985 in the United Kingdom and first used in the United States by commercial laboratories in late 1986 and by the Federal Bureau of Investigation (FBI) in 1988.

DNA typing has great potential benefits for criminal and civil justice; however, because of the possibilities for its misuse or abuse, important questions have been raised about reliability, validity, and confidentiality. By the summer of 1989, the scientific, legal, and forensic communities were calling for an examination of the issues by the National Research Council of the National Academy of Sciences. As a response, the Committee on DNA Technology in Forensic Science was formed; its first meeting was held in January 1990. The committee was to address the general applicability and appropriateness of the use of DNA technology in forensic science, the need to develop standards for data collection and analysis, aspects of the

technology, management of DNA typing data, and legal, societal, and ethical issues surrounding DNA typing. The techniques of DNA typing are fruits of the revolution in molecular biology that is yielding an explosion of information about human genetics. The highly personal and sensitive information that can be generated by DNA typing requires strict confidentiality and careful attention to the security of data.

Answer: Bacterium inhaled from air alongside oxygen can be isolated by mucous membranes and eliminated by multiple immune defenses of the respiratory system.

Explanation:

The respiratory system consists of cilia and mucous membranes which lines the inner surfaces. These surfaces are made up of goblet cells which secrets a layer of sticky mucus. When microorganisms such as bacteria is inhaled along with oxygen, the viscosity and acidity of the sticky mucus inhibits microbial attachment to the underlying cells. The beating of cilia propels the mucus with any trapped bacteria towards the epiglottis where it is swallowed. This process of elimination prevents bacteria from further invading the lower respiratory tract.

Multiple immune defenses of the respiratory system includes:

--> mucosa associated lymphoid tissue (MALT): these includes adenoids and tonsils.

--> lysozyme

--> Surfactants

--> defensin (antimicrobial peptides)

--> alveolar macrophages

The activities of the multiple immune defenses of the respiratory system helps in the isolation and elimination of inhaled bacterium.

Explanation:

If further increase in temperature occurs, it leads to decrease the substrate concentration because with very high temperature the enzyme is unable to perform its function. If the temperature is in optimum range, the enzyme produces more substrate due to favorable environment while on the other hand, if the temperature is below or above the optimum range so the enzyme can't perform its function properly and the substrate produce in small concentration.
