[20pts] Hi, can someone help me with these two questions?

Answer:

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:

First graph.

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.

Explanation:

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.

They typically consist of several steps in the treatment process. These include: (1) Collection ; (2) Screening and Straining ; (3) Chemical Addition ; (4) Coagulation and Flocculation ; (5) Sedimentation and Clarification ; (6) Filtration ; (7) Disinfection ; (8) Storage ; (9) and finally Distribution.

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:

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:

The answer is C.

Explanation:

Atmosphere includes oxygen, nitrogen, and ozone. So, the correct option is (C).

An atmosphere is defined as the gas layer or layers of gases covering a planet that are held together by the gravity of the planetary body. A planet maintains an atmosphere when gravity is high and the temperature of the atmosphere is low.

It is made up of layers of gases like oxygen, nitrogen, and ozone that surround a planet or other celestial body. Earth's atmosphere is composed of approximately 78% nitrogen, 21% oxygen, and one percent other gases.

Earth's atmosphere extends up to 10,000 kilometers above the surface of the planet. After which the atmosphere merges into space.

Thus, atmosphere includes oxygen, nitrogen, and ozone. So, the correct option is (C).

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.

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.

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.
