Answer:

Explanation:

In 1976, The Viking 1 and Viking 2 probes landed on Mars. For six years they transmitted fascinating panoramic views of the red and rocky soil of Mars back to Earth. Twenty years passed before a third probe landed on Mars. In 1997, the Pathfinder probe landed a miniature vehicle named Sojourner on the planet. The probes operated for three months and sent back large amounts of data on the Martian environment. At the same time, the Mars global surveyor probe was placed in orbit to take an overall portrait of the planet. It supplied hundreds of thousands of bits of information, especially on climatic variations.

Answer:

Viking 1 and Viking 2 probes transmitted panoramic views of the red and rocky soils back to Earth after six years later. The Pathfinder probe sent back large amounts of data of the environment especially about climatic variations in only three months. You can tell the technology was very different between these two because of how long it took for each probe to gather data.

Answer:

Epithelial cells are the protective cells. They form the outer covering of the body surface which protects the body from any external danger.Cuboidal epithelial cells, as their name suggests, are shaped like cubes. These are typically found in tissues that secrete or absorb substances, such as in the kidneys and glands. Columnar epithelial cells are long and thin, like columns. These are usually found in places that secrete mucus such as the stomach.

Answer:Cellular respiration in plants and animals involve chemical reactions with oxygen that release stored energy. ... Plants, algae, and many microorganisms use the energy from light, carbon dioxide from the atmosphere, and water to make sugars (food) through the process of photosynthesis, which also releases oxygen.

Explanation:

hope it helps :)

The role of photosynthesis and cellular respiration in the cycling of matter and the flow of energy through the ecosystem is the following:

The fundamental energy source of all ecosystems is the Sun, which sends a large amount of energy to Earth in the form of light and heat.

The various green plants use energy from the sun, water and nutrients from the soil, and carbon dioxide from the air to produce organic matter.

The process by which light is used as an energy source to transform CO2 into organic compounds essential for life is called photosynthesis.

The manufactured organic matter is used by the photosynthetic organisms themselves for the maintenance of their vital processes through cellular respiration.

Energy, once solar energy is transformed by producers into chemical energy by making organic matter in photosynthesis, is transmitted along with matter.

In each transfer of energy, between the different types of organisms there is a release of energy to the environment, in the form of heat.

On the contrary, matter flows cyclically, chemical elements are transferred between living beings and in the physical environment of each ecosystem.

Therefore, we can conclude that the role of photosynthesis in the cycling of matter and the flow of energy through the ecosystem is to produce the transformation not only of inorganic into organic matter, but also of light energy into chemical binding energy, oxygen is released as a waste product and is used by most organisms for cellular respiration.

Explanation: Have a blessed day hopefully this helped!

Answer:

Explanation:

It would take 50 years to return to atmospheric CO2 levels from the year 1800. I know this because I set the fossil fuel usage to 0 and proceeded to simulate 50 years and that’s when the atmospheric CO2 levels returned to 600 GtC.

As per observation It could take 50 years to go back to atmospheric CO2 degrees from the yr 1800.

Each year, there has been no extrade in the quantity of CO2 withinside the ecosystem because of soil and land plants. coal also can be the answer.

Since 2000, the worldwide atmospheric carbon dioxide quantity has grown with the aid of using 43.5ppm, an growth of 12 percent. The contemporary-day document of atmospheric carbon dioxide degrees commenced with observations recorded at Mauna Loa Observatory in Hawaii.

Thus it is well explained.

The five categories of adaptations are migration, hibernation, dormancy, camouflage, astivation.

The term migration has been defined as when the birds, animals, or human beings leaves the native place and move towards a new place due to weather or other physical condition is known as migration. Generally, when it is too much cold the birds of that particular area migrated to the place where they found suitable temperature for their survival.

The stage of dormancy is the stage when seed gets closed and not able to germinate as it closes its outer wall. The term hibernation is defined as the particular time period in which the organism hybernate himself for a period of time when the weather or the outer environment is not safe, or fit for his survival.Generally, when it is too much cold the birds of that particular area migrated to the place where they found suitable temperature for their survival.

Answer:

All these chemicals are primary causes of pollution. Although, only one isn't an air pollutant. Which would make my best Guess C. Nitrate

Explanation:

A. Methane Is the main component in gas and oil. Oil companies have been responsible for polluting our air with about seven million tons of methane per year.

B. Nitrogen gas in general is one of the main air pollutions. otherwise know as Nitrogen dioxide.

C. Nitrates are found in ground waters and transfers into the soils surrounding said waters. Nitrates commonly are a cause of death in infants when drinking tab water or eating crops grown from nitrate infected soils. Adults aren't nearly as infected by this.

D. Carbon Dioxide is a greenhouse gas that pollutes our air and has been a main cause of global warming.

I'm at a loss for answering this question since all of these are polluting our earth in some way. The only way I can think to answer this is that all but one are air pollutants. So maybe the one that is not a air pollutant is the correct answer. My best guess is C. Nitrate

Explanation:

improved water habitats for human recreation

When two oxygen atoms get close to each other, the attractions from the nucleus of both atoms attract the outer electrons.

A negatively charged subatomic particle known as an electron can either be free or attached to an atom (not bound).  The nucleus of an atom is made up of electrons, protons, and neutrons together.

The positive charge of a proton balances the negative charge of an electron. An atom is in a neutral condition when it has the same number of protons and electrons.

There are several ways in which electrons differ from the other particles. They are substantially less massive, exist outside of the nucleus, and show both wave- and particle-like properties.

Therefore, When two oxygen atoms get close to each other, the attractions from the nucleus of both atoms attract the outer electrons.
