Answers

Coal, petroleum, and oil are energy solutions that release pollution into the air. 

Answer:

The correct answers are coal, petrolium and oil.

Explanation:

  • Coal is a fossil fuel that highly contributes to climatic change, polluting not only air but also water and the soil. By burning it, its gases contribute to increase the greenhouse effect and consequently producing global heat. This is affecting all forms of life that depend on these resources, including human beings. Thermal factories of coal for electricity production are the responsible source of CO, CO₂, SO₂ and NOₓ release. During the coal combustion process, several particles are released to air, polluting and being the cause of smog and acid rain. To produce only one tone of energy, coal emits 3.5 tones of CO₂, which is 1.5 more times than gas and 1.3 more times than petroleum CO₂ emission. In spite of its reduced use in the last years, coal is still the principal fuel used by thermal, refineries, chemical, and still work industries.  It is also very important to mention that this production is the cause of the destruction of several species´ habitats and ecosystems that surround the mines.  
  • Petroleum pollution is produced by its accidental or intended release in the environment, which produces adverse effects on all forms of life, directly or indirectly. This contamination involves all the operations related to hydrocarbon extraction and its transport, driving to a gradual environment deterioration, affecting soil, water, air, flora, and fauna.  The areas occupied by the petroleum extraction installations affect the whole ground surface that ends in a completely degraded place. In superficial water sources, petroleum split and other wastes produce a decrease in oxygen, available solids, organic and inorganic substances. Underground water is affected by an increase in salinity by contamination. Ocean water is affected by conducts break in the bottom, or by ship splits. The air ais affected by gas emissions such as CO and CO₂.
  • Oil is also a huge contaminator and it generates a dangerous waste that is very harmful to the environment. Its elimination by incineration or split provokes huge pollution problems in the air, water, and ground. In water, it produces an impermeable film that impedes gas exchange and causes suffocation in the living forms that inhabit there. Only one oil liter contaminates one million liters of water. But if the oil is burned it generates nocive gases that are very toxic because of their content in plumb, chloride, phosphorus, sulfur, among others. Only 5 oil liters burned might contaminate 1 million cm³ of air.  

The major light absorbing pigment in green plant photosynthesis isA)
rhodophyll.
B)
chlorophyll.
C)
cytochrome a.
D)
cytochrome c.

Answers

Chlorophyll is the major light absorbing pigment in green plant photosynthesis. the correct option in regards to the given question is option "B". For the process of photosynthesis it is important for a plant to absorb heat from sunlight to make glucose and water. The absorption of heat from sunlight is done by the chlorophyll present in the leaves. Without the presence of this green pigment in the leaves, the plants would never be able to absorb sunlight and this will ultimately lead to the death of the plant.
I think the answer would be, B. Chlorophyll

How do parasites serve as a density-dependent limiting factor

Answers

Parasites can limit the growth of a population. They take nourishment from their hosts, often weakening them and causing disease or death.
As the population of parasites grow, the population of their hosts tend to decrease.

What evidence suggests the continents were once all together but then drifted apart?

Answers

Answer: The evidences suggesting that the continents were once all together are as follows-

  1. Most of the edges or the boundaries of the continents perfectly matches with the nearby continents.
  2. Similar fossil assemblages has been found in different continents.
  3. Similar rocks have been found at different continents, and also similar age has been observed.
  4. Plate tectonic theory confirmed that all continents earlier were together.
Similar types of rocks in places, same species of animals with slight different evolutions to adapt to climate, the landmasses actually look like they fit together, etc..

When you squeeze lime juice onto sliced avocado or drip orange juice over your sliced apples, you are using citric acid as a competitive inhibitor to prevent oxygen from binding to the active site of polyphenol oxidase (PPO), the enzyme that causes fruit to turn brown.Which model best shows this inhibition?

Answers

Answer:

The correct model is attached as the image.

Explanation:

In this model, there is large green circular in shape on that a medium circular indentation towards the left to the green circle. On the other hand towards the right there are two small circular indentations. There is a green smaller indention is shown as the site where oxygen binds when lime juice is squeezed on avocado.

There is two tiny gray circular structure that is joined together by a spaced line represent the oxygen that moves to bind to the active site. Arrow is connected from this gray structure to the indentation and turn back which shows inhibition. The model is given below.
