Examples of kingdom monera may include blue-green algae - Cyanobacteria and E.coli. Archaea includes halophiles and methanogens.

Kingdom may be defined as the second highest taxonomic rank, just below the domain. Kingdoms are divided into smaller groups called phyla. It is a taxonomic rank that is composed of smaller groups called phyla.

Examples of kingdom Protista may include Amoeba, paramecium, and euglena. Examples of the kingdom Fungi may include yeasts, molds, mushrooms, puffballs, and smuts. Kingdom Plantae includes green, brown, and red algae, liverworts, mosses, ferns, and seed plants with or without flowers.

While the kingdom Animalia is a diverse kingdom that includes invertebrates like snails and sea anemones, and vertebrates like humans and dolphins. They range in size from microscopic rotifers to 100-foot-long blue whales.

Therefore, examples of each kingdom may be significantly mentioned above distinctively.

Answer:

When dissolved in water, acids donate hydrogen ions (H+). Hydrogen ions are hydrogen atoms that have lost an electron and now have just a proton, giving them a positive electrical charge. ... The H+ ions in the acid join with and are neutralized by the OH- ions of the base to form H2O.

Answer:

Ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. It contains biotic or living, parts, as well as abiotic factors, or nonliving parts.

An ecosystem is defined as a location where a bubble of life is created by the interaction of plants, animals, and other species with the weather, topography, and other factors.

Topography is defined as the investigation of surface characteristics and shapes. In order to describe the shape of the terrain, topographic features are particular points, lines, and areas that correspond to local differential qualities of the surface of the terrain.

A self-sustaining unit of living creatures (plants, animals, and decomposers) and their non-living surroundings is called an ecosystem (air, water and soil). Examples: Aquatic plants and animals that dwell in pond water make up the aquatic portion of an ecosystem known as a pond. A biome is a group of associated ecosystems.

Thus, an ecosystem is defined as a location where a bubble of life is created by the interaction of plants, animals, and other species with the weather, topography, and other factors.

Answer:

the lighter fresh water rises up and over the salt water

Explanation:

this is because the salt water is denser

Answer:

When trying to mix fresh/salt water it leads to variable and dynamic chemical conditions, especially salinity because fresh water flowing into the estuary is less salty and less dense than water from the ocean, it often floats on top of the heavier seawater.

Explanation: Science/Chemistry

In addition to carbon dioxide, water and sunlight are the two ingredients that a plant need for photosynthesis. Therefore, the correct option is option A.

Green plants along with certain other organisms convert sunlight into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis by green plants to change moisture, carbon dioxide, plus minerals into oxygen- and energy-rich organic molecules.

It is impossible to overstate the role that photosynthesis plays in sustaining life on Earth. There'd soon be food or even other organic materials on Earth if photosynthesis stopped. The majority of life would vanish, and eventually, the atmosphere of Earth would contain almost no gaseous oxygen. In addition to carbon dioxide, water and sunlight are the two ingredients that a plant need for photosynthesis.

Therefore, the correct option is option A.

Answer:

In heavily deforested areas, soil erosion and nutrient runoff are common after a rainfall. Soil erosion tends to be greater in drier, more mountainous areas, where there is less vegetation to prevent the movement of soil and to absorb the nutrients

Explanation:

Answer:

The soil that provides nutrients for vegetation in ecosystems is also affected by deforestation. ... Some of the carbon dioxide released into the atmosphere comes from dead vegetation that decomposes in the ground. In heavily deforested areas, soil erosion and nutrient runoff are common after a rainfall.

The size of Jupiter is much larger than Earth, meaning it's gravitational pull is stronger. The mass of Jupiter is 318 times bigger than Earth. In order to calculate the gravitational force between two objects with masses of m1 and m2 , the equation is: where G is the gravitational constant (6.67E-11 m3 s-2 kg-1), r is the distance between the two objects, and F is the magnitude of the force between the objects.Every object in space exerts a gravitational pull on every other, and so gravity influences the paths taken by everything traveling through space. It is the glue that holds together entire galaxies. It keeps planets in orbit. It makes it possible to use human-made satellites and to go to and return from the Moon.
