how many molecules are in 2fe203

Answers

Answer 1

Answer:

2 molecules.

Explanation:

In 2Fe203, there are two molecules because Fe203 is a molecule which is  made up of two atoms i.e. iron and oxygen atom. In one molecules of Fe203, there are 5 atoms so in 2 molecules of Fe203, there are 10 atoms. The digit present in front or to the left side shows number of molecules so that's why we can say that there are only two molecules in 2Fe203. The name of this molecule is iron oxide.

The relationship between bacteria and legumes that results in nitrogen is best described as _______.
a.
parasitic
b.
mutualistic
c.
commensalistic
d.
none of the above

Answers

The answer is b. Mutualistic

The relationship between bacteria and legumes that results in nitrogen is best described as mutualistic.

WHAT IS MUTUALISM?

Mutualism is the type of association between two organisms in which both parties benefit from one another.

An example of mutualism is the relationship between bacteria and leguminous plants.

Leguminous plants provide shelter for the bacteria while bacteria help the plant to fix atmospheric nitrogen.

Therefore, the relationship between bacteria and legumes that results in nitrogen is best described as mutualistic.

1. Compact, complex animals have internal exchange surfaces that are extensively branched or folded, providing a large _____________.
2. In the _____________, nutrients are absorbed across the many fingerlike projections of the lining of the intestine.
3. In the _____________, oxygen and carbon dioxide are exchanged across the epithelial linings of sacs at the tips of tiny air tubes.
4. In the _____________, wastes are removed from the blood across the epithelial linings of excretory tubes.
5. The _____________ transports materials between the exchange surfaces of other organ systems and body cells.
6. Body cells are bathed in _______________, and exchange between body cells and the blood takes place through this fluid.

Answers

Answer:

1.) Surface area

2.) Digestive system

3.) Respiratory system

4.) Urinary system

5.) Circulatory system

6.) Interstitial fluid

Explanation:

In higher complex animals, such as the vertebrates, the internal exchange surfaces are modified in such a way to facilitate the transfer of materials from cell to cell in the body. As animal size increases, diffusion distances increase and the ratio of surface area to volume drops. Larger organisms have had to evolve specialized systems that are made up of structures that provides a large surface area for internal exchange of materials. Examples of these systems include:

--> DIGESTIVE SYSTEM: The fingerlike projections of the lining of the intestine provide a large surface area for the absorption of nutrients.

--> RESPIRATORY SYSTEM: This ends with a sac called the alveolar sac. The anatomical arrangement of capillaries and alveoli produces a very large surface area that is available for gas exchange.

--> URINARY SYSTEM: wastes are easily removed from the blood across the epithelial linings of excretory tubes.

--> CIRCULATORY SYSTEM: transports materials between the exchange surfaces of other organ systems and body cells. An example is seen in the relationship between the alveoli and the capillaries surrounding it.

For any exchange of materials to occur between cells the fluid known as the INTERSTITIAL FLUID which fills the intercellular spaces allows dissolved materials to be exchanged between body cells and the blood

How did the polar bears get their white fur?A.Bears have various alleles for fur color ranging from dark to light. Those bears with the lighter fur had a better chance of survival in the biome, so they lived and reproduced passing on their light colored gene to their offspring. As generations passed, white fur became more common.B.As a polar bear grows up, its fur gradually gets lighter, so by the time they are a teenager, they have fully white fur and are then best suited to survive in their environment.C.Polar Bears migrated from the Pacific Northwest up to the Tundra and Arctic because they knew that they would have a better chance of surviving in this cold region.

How is a person exposed to toxins? Explain each. (There are three ways to be exposed to toxic substances.

Answers

Answer:

Three ways to be exposed to toxic substances:

1. Inhalation - Inhalation is when we are breathing something into our lungs. For example, a firefighter may ingest toxic gasses and chemicals when entering a burning house.

2. Ingestion - Ingestion is when we are taking something by mouth. If someone eats a piece of cheese that is expired, they will most likely get food poisoning.

3. Skin contact - Skin contact is when a substance is in direct contact with our skin. For example, if someone spills an acidic substance on their arm during science class, this is considered a toxin and they may get a painful chemical burn.
