A viral outbreak in a city needs to be traced to its source. How can wastewater be used to trace the viral outbreak?
O it can be collected at different locations in the city and tested for the virus.
O It can be treated at all locations to prevent viral spread in drinking water.
O It can go through ozonation and chlorination to prevent virus spread.
Viral outbreaks are spread through wastewater treatment facilities

Answers

Answer:

a

Explanation:

it a

The wastewater can be used to trace the viral outbreak by going through ozonation and chlorination to prevent virus spread. The correct option is C.

What is ozonation of water?

One of the most powerful oxidants is ozone, a gas composed of three oxygen atoms (O3).

Ozonation is a type of advanced oxidation process that produces highly reactive oxygen species capable of attacking a wide range of organic compounds as well as all microorganisms.

Drinking water purification processes include chlorination and ozonation.

The primary distinction between chlorination and ozonation is that chlorination uses chlorine to disinfect drinking water, whereas ozonation uses ozone to disinfect drinking water.

When compared to chlorination, ozone has a higher disinfection effectiveness against bacteria and viruses.

Furthermore, the oxidizing properties can reduce the concentration of iron, manganese, and sulfur, as well as reduce or eliminate taste and odor issues.

Thus, the correct option is C.

What is homeostasis?

The state of constant internal, physical, and chemical conditions maintained by living systems is known as homeostasis.

This is the state of the organism's optimal functioning, and it includes many different factors, such as core temperature and adequate fluid, being kept even within those pre-set limits.

Homeostasis is the state of balance within all physical systems required for a body to function properly and survive.

The nervous system and nucleus functions the same, as the nervous system makes control and co-ordination with whole body, nucleus also controls all cell's activities.

Digestive system works by breaking down the food and making it into its simplest form, just like that lysosomes also bears digestive enzymes.

Just like respiratory system produces energy by oxidation of food, mitochondria also provides energy to cell by generation of ATP.

The integumentary system is the protection layer of the body that prevents outside material to come inside or vice versa, just like cell membrane of the cell.

describe the uptake and movement of water from the soil to the leaves​

Answers

Answer:

After traveling from the roots to stems through the xylem, water enters leaves via petiole (i.e., the leaf stalk) xylem that branches off from that in the stem. Once water leaves the xylem, it moves across the bundle sheath cells surrounding the veins.1-Water is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. 3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.Plant water uptake, or transpiration, represents the process by which water in soil is drawn into plants and returned in gaseous form to the atmosphere through leaf stomata.Water transport also occurs at the cellular level, as individual cells absorb and release water, and pass it along to neighboring cells. Water enters and leaves cells through osmosis, the passive diffusion of water across a membrane.Most of the water that a plant takes in enters through the root hairs.

Answers

Answer:The geosphere consists of the core, mantle and crust of the Earth.

The atmosphere contains all of the Earth’s air and is divided into troposphere, stratosphere, mesosphere, thermosphere and ionosphere.

The hydrosphere contains all of the solid, liquid and gaseous water on Earth, extending from the depths of the sea to the upper reaches of the troposphere where water is found. Ninety-seven percent of the hydrosphere is found in salty oceans, and the remainder is found as vapor or droplets in the atmosphere and as liquid in ground water, lakes, rivers, glaciers and snowfields.

The biosphere is the collection of all Earth’s life forms, distributed in major life zones known as biomes: tundra, boreal forest, temperate deciduous forest, temperate grassland, desert, savannah, tropical rainforest, chaparral, freshwater, and marine.

[1] Although the four systems have their unique identities, there is substantial interaction between them. Environmental scientists study the effects of events in one sphere on the other spheres. For example, a volcanic eruption in the geosphere may cause profound direct and indirect effects on the hydrosphere, atmosphere and biosphere as follows:

Example 1 (Volcano) On May 18, 1980, Mount Saint Helens, in the state of Washington, erupted. This event altered the surrounding environment, and provided scientists with an opportunity to study the effects of volcanic eruptions on the geosphere, hydrosphere, atmosphere and biosphere. Such studies are vital because volcanic eruptions will continue to occur, and will have increasing impact on humans as people continue to settle lands closer to dormant volcanoes. The following are but a few of the myriad of interactions resulting from a volcanic eruption.

Volcano >> geosphere >> atmosphere >> hydrosphere >> biosphere

Volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. These particles serve as nuclei for the formation of water droplets (hydrosphere). Rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere). Particulate matter in the air (atmosphere) falls out, initially smothering plants (biosphere), but ultimately enriching the soil (geosphere) and thereby stimulating plant growth (biosphere).

Volcano >> geosphere >> hydrosphere >> biosphere

Volcanoes (events in the geosphere) may release a substantial amount of hot lava (geosphere), which causes mountain glaciers (hydrosphere) to melt. Mudflows (geosphere) and flooding may occur downstream from volcanoes and may inundate streamside communities (biosphere).

Volcano >> geosphere >> atmosphere >> biosphere >> geosphere

Volcanoes (events of the geosphere) release a large amount of carbon dioxide (atmosphere), the raw material for sugar production in plants (biosphere). This may increase photosynthetic production and eventually increase the amount of biomass, which, after a very long time, forms coal and oil deposits (geosphere).

Volcano >> complex interactions

Volcanoes (geosphere) may emit large quantities of sulfur dioxide (atmosphere). When atmospheric sulfur dioxide combines with water (hydrosphere), sulfuric and sulfurous acid form. Rain (hydrosphere) may bring these acids to the Earth, acidifying soils (geosphere), lakes and rivers (hydrosphere). Acidic water leaches nutrients from the soil (geosphere) into the water table (hydrosphere), making the soil less fertile for plants (biosphere), and the subterranean water supply (hydrosphere) less potable for humans (biosphere). Acid rain falling on lakes and streams reduces the pH of the water (hydrosphere), which may result in a decrease in phytoplankton and zooplankton growth (biosphere). If photosynthesis is reduced, atmospheric concentrations of carbon dioxide can build up and stimulate global warming (atmosphere) which may contribute to increased melting of glaciers (hydrosphere)

Explanation:

Both the mining and burning of fossil fuels are interactions between geosphere and biosphere which damages the atmosphere. Thus, correct option is B.

What is atmosphere?

The atmosphere contains air which is a blanket of gases that surrounds the planet- Earth and the gases that we breathe. The atmosphere is held in the position near the Earth surface by gravitational attraction. A barometer is an instrument used to measure the air pressure. Argon, oxygen and nitrogen are some of the main gases which constitutes the atmosphere.

The geosphere of Earth consists of core, mantle and crust of the planet. The atmosphere consists of all Earth's air, gases and it is divided into different zones on the basis of height i.e., troposphere, stratosphere, mesosphere, thermosphere and ionosphere.

The atmosphere provides geosphere, all the heat and energy required for the breakdown of rock and erosion. The biosphere of Earth receives all the gases, heat, energy, and sunlight from the atmosphere.

Therefore, correct option is B.
