Answer:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
Explanation:
Answer:
Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch
why are proteins considered polymers but liquids not?
Explanation:
Why are proteins considered polymers but lipids not? Lipids do not align with the definition of a polymer. Proteins are made of long chains of monomers that result in a product with new properties, but lipids are macromolecules that are in fact not made up of tiny components that make up a chain.

The statement best summarizes the role of households in the flow of goods is households exchange money for products in resource markets. Thus, option C is correct.
Who are the consumers among households?The final consumers of the goods and services produced by the businesses are the households. According to their tastes and preferences, they create demand in the market. The businesses supplied and produced goods in response to customer demand. As a result, a nation's production line is determined by its households.
To run a business, workers are needed, and business owners, managers, and employees also have families. In return for labor, the business pays wages, which increase household income.
Therefore, A company's output may fall somewhere in the middle of these two ideas. A landscaping company, for instance, might offer a homeowner a service and sell them a tree as a product.

The majority of marine organisms are found in coastal regions, rather than the open
ocean. Which of the following best explains why?
O Salinity is usually much higher in coastal regions.
O Temperatures are cooler in coastal regions.
OOcean currents bring nutrient-rich water into coastal regions.
OThe shallow waters of coastal regions provide less Oxygen.
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.
Describe how a bacterium inhaled on air alongside oxygen can be isolated by the respiratory system
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:
What are convergent boundaries?
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
what's hydrotropism?
Explanation:
Hydrotropism is a plant's growth response in which the direction of growth is determined by a stimulus or gradient in water concentration. An example of positive hydrotropism is the growth of plant roots towards higher relative humidity level.

A. There is a 50% chance of having round, yellow peas
B. There is no chance of having round, yellow peas
C. There is a 100% chance of having round, green peas
D. There is no chance of having any wrinkled, green peas
Answer:
D, there's no chance of having any wrinkled, green peas
In the given scenario, there is no chance of having any wrinkled, green peas. The correct option is D.
What is dominant and recessive characters?When a trait has two different forms at the gene level, dominant and recessive traits exist. The dominant trait is the trait that first appears or is visibly expressed in the organism.
The recessive trait is one that is present at the gene level but is masked and does not manifest itself in the organism.
A trait that is expressed only when the genotype is homozygous; a trait that is masked by other inherited traits but persists in a population among heterozygous genotypes.
Dominant inheritance refers to the inheritance of traits that are typically passed vertically from parent to child, with both the parent and the child affected by the trait or disorder associated with that gene.
In the given image, there is no recessive alleles, all are in combination with the dominant one, so it is not possible to have wrinkled, green peas.
Thus, the correct option is D.

How did Charles Darwin use the concept of density dependent factors in his Theory of Evolution
Answer:
Density-dependent factors are defined as the biological factors which are utilized by the population as a resource for example- food and shelter. Charles Darwin uses the concept of density-dependent factors in his Theory of Evolution to show how it affects population growth and mortality.
Charles Darwin used factors like competition, predation, and parasitism in his Theory of Evolution. He explained that habitats are limited by space and resource availability, and only the fittest organism will survive the competition.
Predator-prey relationships create density-dependent limiting factors and balance the ecosystem with limited organisms. If predators will increase in an ecosystem it will decrease the population of prey and after a certain time there will be a shortage of food as they are limited resources.

Because molecules will move from one side to another to come to an equilibrium, or balance of concentration, the _________________________moves from side B to side A, so the water level on side A goes _____________________________.
Answer:
Water, up
Explanation:
In the process of movement water in the diffusion of water the net movement of water goes from higher concentration to the low concentration area. The movement of water move form one side to other side until it reaches an equilibrium and the level of water on the other side goes up.
Hence, the water molecule will move from from side B to side A until it reaches equilibrium and the water level on side A goes up.

What were the sources of gases in Earth's early atmosphere?
Where did oxygen come from? Why is oxygen so important for life on Earth?
How did the first oceans form?
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.
Fossil fuels, such as coal and oil, get their names because they form from fossilized organisms trapped under extreme
pressure and heat from the center of Earth. Explain how the model shows the requirements for fossil fuel formation.
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.
What is 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.
