Explanation:

Lake Tahoe in Devada suffered from a severe eutrophication damage until control and remediation activities were carried out. Option C is correct.

The term eutrophication refers to the biological process produced in water by an oversupply of nutrients or organic matter.

Human pollutive activities are closely related to this artifical eutrophication and, in several cases, are the cause.

Nutrients, mainly compounded with nitrogen or phosphorous, favor phytoplankton multiplication, especially cyanobacteria. Primary productivity enhances due to the sharp increase in these microscopic organisms.

The overgrowth impedes light reach deeper areas, affecting the biota living there. Sedimentation is caused by the death of plants and algae that sink to the bottom. These sediments rich in organic matter suffer decomposition in the presence of oxygen.

When oxygen disappears, anaerobic bacteria act and produce fermentation.

Both processes, phytoplankton overgrowth on the surface and fermentation on the bottom, originate toxic compounds that damage the animals.

Animals die, creating more sediments in the bottom where there are anaerobic conditions.

Decomposition and fermentation processes increase, producing a bad smell.

This whole cycle continues as long as cyanobacteria are present.

Among the main human activities responsible for eutrophication we can mention tourism, agriculture and the cattle industry, and the lack of controlled organic waste treatment.

This what occurred in the Lake Tahoe, in Devada, after the impact caused by tourism, deforestation, and the cattle industry.

This lake suffered from a severe eutrophication damage until control and remediation activities were carried out.

The correct option is C.  Lake Tahoe in Devada.

Answer:

Index fossils are fossils of organisms that lived during only one short period of time. A layer rock with an index fossil in it is close in age to another layer of rock with the same type of index fossil in it. Even though rock layers are of different regions, index fossils indicates that the layers are close in age.

Answer

C02 is produced in the body.

Explanation:

Every tissue in the body utilize oxygen for its metabolic activities and excrete carbondioxide.Every tissue is supplied by blood. Blood transports oxygen from heart to the tissues used for metabolic activity.Tissue produces carbondioxide as a result of metabolism.Blood transports back carbondioxide from tissues to lungs to expel it out from the body. Inside the lungs, CO2 from blood vessels diffuse into lung tissue (simple diffusion) and then lungs exhale it. That'why there is additional percentage of carbondioxide in the exhaled air.

   NASA's Artemis program has a goal of landing humans on the moon in 2025 to begin building a base camp. This long-term human presence on the lunar surface will help NASA prepare for human space exploration missions of greater distance and duration, including an eventual crewed flight to Mars. Space can help us prepare the feutre Space exploration allows us to prove or disprove scientific theories developed on Earth. Studying the solar system, for example, has brought us insights into such phenomena as gravity, the magnetosphere, the atmosphere, fluid dynamics and the geological evolution of other planets. That has led to the development of various technologies that feed back into the economy and improve our lives on Earth. Without space programs, we wouldn't have GPS, accurate weather prediction, solar cells, or the ultraviolet filters in sunglasses and cameras.

Explanation:

There hope it helps Also you could've done a little bit of resheerch skimmed a cupple sights to get an idea on what to wright about then go from there  its just an idea thoe

We have learned more about gravity, the magnetosphere, the atmosphere, fluid dynamics, and the geological evolution of other planets, for instance, through studying the solar system. This sparked the creation of numerous technologies that benefit the economy and enhance life on Earth.

In 2025, astronauts will be sent to the moon as part of NASA's Artemis mission to begin creating a base camp. This prolonged human presence on the moon's surface will help NASA get ready for longer-duration human space flight missions, such a possible crewed trip to Mars.

Additionally, you could have done some research by scanning a few websites to get an idea of what to write about before moving on from there.

Therefore, We wouldn't have GPS, precise weather forecasting, solar cells, or ultraviolet filters in eyeglasses and cameras without space missions. We can prepare the feutre by using space. We can use space travel to support or refute scientific hypotheses that were formed on Earth.
