why do we see different phases of the moon.
Answer:
The Moon itself does not generate light; it is lit up by the Sun. As the Moon orbits the Earth, the portion of illuminated Moon that we see changes – giving rise to the phases of the Moon. ...

In addition to carbon dioxide, what other two ingredients does a plant need for photosynthesis? ( A: water and sunlight B: Sunlight and soil C: sunlight and oxygen D: water and 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.
What is photosynthesis?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.

What happens to salt water and fresh water when you try to mix them.
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.

Describe: What happens to a hydrogen atom in an acid when the acid is dissolved in water?
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.

Explanation:
Answer:
The soil that provides nutrients for vegetation in ecosystems is also affected by deforestation. ...

An ecosystem is defined as
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.
What is topography?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.
