The right options are;

1. amount of nitrogen, oxygen, and other elements dissolved in water.

2.wetlands.

The nutrient availability of aquatic ecosystems is the amount of nitrogen, oxygen, and other elements dissolved in the water.

Nutrients are chemical elements, and sources of nourishment that are important to the development of plant and animal life. In healthy aquatic ecosystems such as rivers, nutrients are required for the growth of the organisms in the entire aquatic ecosystem. The most common nutrients in aquatic ecosystems include oxygen, nitrogen, and phosphorus.

A wetland is an ecosystem that is covered by shallow water, either periodically or permanently. Wetlands usually emerge from underground sources in mountains or hills.

Bogs get their water from precipitation, so they don't have many nutrients. Marsh plants are adapted to waterlogged soil Swamps have plants like trees and shrubs. Rivers always have flowing currents and pick up sediment as they flow. Lakes are bodies of water on land.  Wetlands act as filters for nutrients and pollutants dissolved in the water. Estuaries are wetland regions where freshwater rivers mix with ocean water.

Explanation:

A wetland is a biome which has both water and land that are intermixed in various ways. According to the type of the wetland, the ecosystem differs.

Bogs: Wetland with water from precipitation and no inflow or outflow of surface or ground water.  

Soil: Acidic, infertile with less nutrient content

Vegetation: Acid-loving plants

Swamps: Forest wetlands near rivers and lakes.

Soil: well draining, mineral soil

Vegetation: Trees and bushes. Swamps are classified according to the vegetation, like coniferous swamp, hardwood swamp, shrub swamp etc

Marsh: Wetlands mostly inundated with water leading to waterlogged soil  

Soil: Organic and mineral soil

Vegetation: Hydrophytic plants adapted to waterlogged soil

Estuaries: Wetland regions enclosed by land one side where fresh water mixes with saline ocean water.  

Soil: Saline alkaline soil

Vegetation: Mangrove trees

Rivers and lakes are water bodies that form a part of wetlands.  

Rivers are flowing water bodies which flows through water current and picks up sediments as it flows.

Lakes are stationary water bodies that are enclosed by land mass on all its sides.

The wetlands act as a natural filter and receive all the sediments, pollutants etc which are dissolved in water and carried by the rivers and other water sources.

No significant difference between mean and Expected value

Step-by-step explanation:

Hypothesis

H0 : u = 77.5

H1: u is not equal to 77.5

Alpha = 0.05

Mean = Σxi/n

= 77.09+75.37+72.42+76.84+77.84, +76.69+78.03+74.96+77.54+76.09+81.12+75.75/12

= 919.74/12

= 76.645

We get the variance s² = xi² -n(barx)²/n-1

= 77.09²+75.37²...75.75²-12(76.645)²/11

When we solve this out

We get 4.3486818182

T test = barx - u/(s/√n)

= (76.645-77.5)/√4.3486818182/12

= -1.420293

T critical = Tn-1, alpha/2

= 2.200985

The test statistic is less than 2.201 so we accept the null hypothesis at 0.05 level of significance. And then conclude that there is No significant difference between mean and Expected value.

a.  both support a large number of plants and animals adapted for aquatic living

Explanation:

The freshwater and the marine ecosystem are home to a large number of fora fauna and consist of diverse species that feed and survive on the characteristic of its water bodies. Some need saline while others need freshwater systems. Global warming hazardous to both and thus both of these water systems are in constant change.

The correct answer is b. ocean and freshwater system conditions generally remain constant throughout the year. This is not true because they are very different. For examples, freshwater rivers can completely freeze during the winter while oceans can't freeze completely, not even a bit. Also, the animals inside have completely different body structures to fight these changes.

Answer and explanation: This is a Robinson map of the world. The Robinson projection was created in 1963 by the geographer Arthur Robinson. The projection seeks to balance different types of distortion. The projection isn't perfect, but it is considered more visually appealing than others. It balances small distortions of area, shape, distance, and direction.
