What is the most significant difference between freshwater aquatic ecosystems and marine ecosystems?​

Answers

Answer 1

Answer:

main difference between freshwater and marine life is the habitat they come from in the wild. Freshwater fish live in streams, rivers and lakes that have salinity of less than 0.05 percent. Depending on the species, fish can survive in temperatures ranging from 5 and 24 degrees Celsius

Explanation:

Answer 2

An aquatic ecosystem derives its identity from the interaction between its watery environment and the living organisms that inhabit it. The two types of aquatic ecosystems are freshwater and marine, and the main difference is the salinity concentration.

below.

Answers

The water , the dirt, and the sun

The abiotic factors that are present in the image are the light from the sun, the air, the mountain, the water, etc., as abiotic substances, also known as abiotic factors, are non-living components of an ecosystem.

What are abiotic factors?

Abiotic substances include physical and chemical factors that affect the ecosystem, such as water, air, light, temperature, soil, nutrients, minerals, etc, where as water is an abiotic substance and is essential for many cellular processes and regulating body temperature, light is necessary for photosynthesis, which is the process that allows plants to produce energy from sunlight, and temperature is important because it affects the metabolic rate of organisms, and extreme temperatures can cause stress or even death.

Hence, the abiotic factors that are present in the image are the light from the sun, the air, the mountain, the water, etc.

Label all of the components of this DNA structure with the following terms: Phosphate sugar backbone, nitrogenous base, hydrogen bonds.

Answers

Answer:

Phosphate sugar backbone:                                                                                              

The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

Nitrogenous base:                                                                                              

Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.

Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine.

Purines on the other hand make 5-sided and 6-sided rings. Examples of purines are Guanine and Adenine.

The nitrogen bases are helped together through hydrogen bonds.

Hydrogen Bonds:

A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

Answers

Down below

Explanation:

I would modify seismograph resources by requesting reports from earthquake stations that felt the tremors.  I would then use the reports and look at the arrival time of the p waves and the s waves.  If a station recorded the s waves arriving much quicker than the others, I can safely say that the epicenter was in that area.  From there, I can request reports in that area and use the triangulation method to pinpoint the exact location.

How does the ocean interact with land and air?

Answers

Answer:

Explanation:

One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.

The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.

Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents. Currents are movements of ocean water in a continuous flow, created largely by surface winds but also partly by temperature and salinity gradients, Earth’s rotation, and tides. Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.

Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.

#4

Explanation:

just did the test

U-shaped valley include action of glaciers, form in mountainous region, and wider as well as more gradual base. V-shaped valley is formed by strong streams, erosive, and deeper than they are wide.

What is a valley?

Valleys are low-lying areas of land that have been eroded and washed away by the combined elements of gravity, water, and ice. Some dangle, while others are feeble. They are all in the shape of a "U" or "V."

Humongous frames of snow and ice slowly creep downhill, seeking the least resistance. As the glaciers seep, they start picking up rocks and grind away at the valley floor and sides, forming a "U" and transforming the "V" into a "U." When the glacier melts, it leaves a U-shaped valley where the snow flowed.

U-shaped valleys are formed by glaciers, have a wider and more gradual base, and are found in mountainous areas. Strong, erosive streams form a V-shaped valley that is deeper than it is wide.

Thus, V-shaped valley include options 1, 2, and 4. U-shaped valley is 3, 5, and 6.

Amoeba moves by an arm-like structure emerging from its body and contains microtubules within the arms. Euglena is flagellated microorganism moving by flagella.

Paramecium is an aquatic unicellular microorganism having special whip like structure called cilia which moves it in back forth. Ciliary bodies are like oars to move in a direction.
