Answer:

Aquaculture

Explanation: Its is the practice of culturing of aquatic life

Aquaculture is  technology have allowed for the raising and harvesting of fish for commercial sale.

The farmer's attempts to speed up and improve the growth of aquaculture species are what define aquaculture as a form of farming.

Aquaculture is the process of increasing populations of freshwater, brackish water, and saltwater species in artificial or semi-natural conditions, in contrast to commercial fishing, which also entails catching wild fish.

In contrast to fishing, these methods enable the selective expansion of production of the species that humans desire the most.

In coastal areas, the main potential threats to marine health are poisons, dregs, and overflow. The health of the marine ecosystem offshore is also assessed.

A natural researcher may be necessary, for example, to take into account the impact of an oil slick or other compound risk in the sea. In order to see concerns like the substance cosmetics of residue, the effect of disintegration, and the impact of digging sea bottoms on the marine condition, natural researchers also study the benthic conditions on the sea floor.

Answer:

1) Weathering, Erosion, Disposition

2) Physical weathering is the breakdown of large rocks into fragments by physical forces; the chemical composition of the rock is not changed. Chemical weathering is the breakdown of rock by chemical reactions; the chemical composition is changed.

3) The four forces of erosion are water, wind, gravity, and glaciers.

4) Because the velocity of the river slows down a great deal when it reaches the large body of water, the sediment that the river was carrying is deposited along the mouth of the large body of water.

--------------------------------------------------------------------------------------------------------

Abrasion: Abrasion is the breaking down and wearing away of rock material by the mechanical action of another rock. Three agents of physical weathering that cause abrasion are moving water, wind, and gravity. Also, rocks suspended in thence of a glacier can cause abrasion of other rocks on Earth's surface. This would be a prime example of physical weathering, or mechanical weathering.

----------------------------------------------------------------------------------------------------------

Acid Precipitation: Acid rain causes less erosion than normal rainwater does. Rainwater can break down rocks by dissolving minerals in the rocks. Acid rain is rainwater that is more acidic than normal rainwater. Acid rain can also dissolve the minerals in rocks faster than normal rainwater can. This is chemical weathering.

--------------------------------------------------------------------------------------------------------

Animal actions: Animal and plant mobility is a factor in biological weathering. For instance, a plant may grow in a gap in a rock and, as its roots spread, cause the fracture to expand. A rabbit may also burrow into a crack in a rock, making it wider and eventually separating the rock. This is an example of physical weathering.

---------------------------------------------------------------------------------------------------------

Ice wedging: Ice wedging ,sometimes known as frost wedging ,can also cause rocks to break apart. Ice wedging causes cracks in rocks to expand as water seeps in and the water freezes and expands opening the crack further. Rocks formed under pressure deep within earth can become exposed at the surface. This is physical weathering

----------------------------------------------------------------------------------------------------------

Oxidation: Oxidation is another kind of chemical weathering. It occurs when oxygen from air dissolves in water and combines with chemicals in the rocks to form oxides. if the rock contains a lot of iron, then oxidation produces a brown material called iron oxide. This looks like rust on the rock.

Weathering is the chemical and mechanical breakdown of exposed rock. The chemical changes alter the minerals and make them softer, and mechanical weathering physically breaks rock into smaller and smaller pieces.

Erosion is the REMOVAL of those chemically and mechanically softer and broken pieces of rock from their original locations, by gravity, water, ice or wind. Erosion is transport (and as a result, fresh unaltered rock is exposed to wind, water and weather, and THAT becomes weathered in turn). The material being transported is ‘sediment’: sand, silt, mud and gravel.

Deposition is when the weathered and eroded (transported) material is dropped and settles down elsewhere, forming a ‘deposit’ of transported rock material.

If this deposit remains undisturbed long enough, and is buried by enough arriving material, it will eventually go through compaction and chemical reactions forming cement between the grains - thus resulting in a brand new, sedimentary rock.

Weathering, erosion, transport, deposition, compaction and cementation are part of the ‘rock cycle’.

Let’s start with basalt that form at mid ocean spreading centers. At mid ocean spreading centers rock material from the earth’s mantle continuously melts due to continuous decreasing in pressure from the oceanic crust spreading at this point. The molten rock quickly cools at the earth’s surface and forms rock known as basalt that makes up the oceanic crust all over the world. The newly produced oceanic crust rock slowly moves towards a boundary with a continental crust where the oceanic crust subducts beneath the continental crust due to the oceanic crust having a higher density than the continental crust. This is where things get a bit more interesting.

Answer for Q1: C. burn hazardous wastes

Answer for Q2: B. buried in a special landfill

Answer for Q3: A. radioactive

Incinerators are used to burn hazardous wastes. Incinerators can help to reduce the risk of exposure to hazardous wastes by destroying harmful substances and reducing the volume of waste materials. Hence option C is correct.

Incinerators are facilities designed to burn waste materials at high temperatures, typically ranging from 800°C to 1200°C. They are used to dispose of various types of waste materials, including hazardous wastes, medical wastes, and municipal solid wastes.

The primary purpose of incinerators is to reduce the volume of waste materials and to destroy any harmful pollutants or pathogens that may be present in the waste.

When waste materials are burned at high temperatures, the organic matter is converted into ash and gases, which are released into the atmosphere or captured and treated before release.

Incineration is often used for hazardous wastes, which are defined as wastes that are potentially harmful to human health or the environment. These wastes can include chemicals, solvents, pesticides, batteries, and other materials that are toxic, corrosive, flammable, or reactive.

Hazardous wastes must be handled and disposed of carefully to minimize the risk of exposure to humans and the environment.

Hence option C burn hazardous wastes is correct.

The particles of the substance initially had high Kinetic Energy.​

Gas particles move quickly in all directions and regularly collide with one another and the container's side. The particles gather kinetic energy and accelerate as the temperature rises. The particles' real average speed is influenced by their mass and temperature.

In liquids, particles are quite close together and move with random motion throughout the container. Due to the closer proximity of the particles, collisions between them happen more frequently than in gases even if particles are moving quickly in all directions.

Environmental factors often influence traits independently of genes. But not always. Sometimes the environment changes a gene—either its DNA sequence or its activity level. Either of these effects can change the proteins that are made from a gene, which in turn affects traits.

Answer:

d isotope concentration

Explanation:

A fossil can be defined as the mineral impression or remains of living organisms such as plants and animals that are prehistoric in nature.

Isotopes can be defined as the atom of an element that has the same number of protons but different number of neutrons. This ultimately implies that, the isotopes of an element have the same atomic number (number of protons) but different atomic.

We can accurately determine the age of a rock or fossil by measuring its isotope concentration. This can be achieved through the use of radiometric dating.

In Science, this process is known as absolute dating and it can be defined as a process used to accurately determine the age of a rock or fossil by measuring the decay of isotopes associated with the rock or within the fossils.

Hence, these informations when properly obtained is used to determine the age of a rock or fossil because the parent material decays into a stable daughter elements at a constant decay rate.

Answer:

Due to different pigments.

Explanation:

The multicellular algae are red, green and brown because of the presence of pigments. The red algae are red in colour because of the presence of the phycoerythrin which is a type of pigment. This pigment reflects red light due to already presence in its body and absorbs blue light that is necessary for photosynthesis process. The brown algae contain fucoxanthin pigment and green algae contain xanthophylls pigments that are responsible for its colour so we can conclude that these different types of pigments are responsible for the different colour of algae.

The picture indicates the structure of RNA because it has URACIL.

Ribonucleic acid (RNA) is a nucleic acid that is present in all living cells that has similarities in structure to DNA. Unlike DNA, RNA is often single-stranded. An RNA molecule is made of alternating phosphate groups and sugar ribose, as compared to the deoxyribose that is found in DNA. Uracil is the nitrogenous base that is present in RNA.

It is made up of nucleotides which are ribose sugars that are attached to nitrogenous bases and phosphate groups. Nitrogenous bases such as adenine, guanine, uracil, and cytosine are present in them. RNA is mostly present in single-stranded, but there are special RNA viruses that have double-stranded.

The scale of the model is 1:25,000. So, the correct option is B.

Scale models are used to represent things or places at a smaller, more manageable size while maintaining proportionality. They are often employed in many different disciplines including geography, engineering and architecture.

By comparing the length of the model to the length of the actual river, one can estimate the scale of the model.

The scale can be determined by dividing the length of the actual river by the length of the model, where the model is 1 m long and the actual river is 25,000 m long:

Scale = Length of actual river / Length of model

Scale = 25,000 m / 1 m = 25,000

Therefore, the scale of the model is 1:25,000. So, the correct option is B.
