A truck carrying fertilizer crashed near a stream within a few miles from this karst feature. The fertilizer spilled into the stream and was carried towards the sink hole. What effect will this have on the karst aquifer? Would you want to drink water from this aquifer?
Answer:
Eutrophication effect
Explanation:
The term eutrophication refers to the enrichment of surface water with nutrients. This process is related to human pollution activities.
Eutrophication is the biological process that generates in water by an oversupply of nutrients or organic matter. This matter, mainly compounded with nitrogen or phosphorous, favors the multiplication of phytoplankton (microscopic plants growing on the water surface) and other aquatic plants. This overgrowth leads to an enhance in primary productivity.
Little by little begin sedimentation, caused by the death of some vegetable organisms that sink in the bottom. These sediments rich in organic matter suffer decomposition in the presence of oxygen.
When oxygen disappears, anaerobic bacteria act and produce fermentation.
On the surface, plants and phytoplankton keep growing, creating a mantle that impedes the light to reach deeper areas. The overgrowth of phytoplankton on the water surface and the fermentation processes in the bottom originate toxic compounds that damage the animals. Animals die, creating more sediments in the bottom where there are anaerobic conditions. Decomposing processes and fermentation increases, producing a bad smell.
The result of eutrophication is the stratification of the water mass:
First superficial layer, the overgrowth of blue-green algae produce toxins and interrupt the pass of light to deeper areas. The surface then becomes warmer. The second layer might have oxygen available for the animals.In the third layer, there is no oxygen, so life is not possible for animals or plants.In the fourth layer, there are animals and plants remains in the process of sedimentation.At the bottom, there is organic matter and anaerobic bacteria that are in charge of decomposition and fermentation, also producing toxic gases and smell.

The DNA sequence that makes up the genetic code of an organism determine which traits the organism will exhibit
Answer:
How are the instructions coded by DNA translated into an organisms physical traits. They are translated into proteins which express an organism's physical traits. In DNA, the structure and size of the four nitrogen bases allows only for one kind of base to pair with one other kind. This is called the base-pairing rule.

What are some of the issues that come with catching shrimp in the wild? What are some of the problems associated with fish farms?
Answer:
Explanation:
There are many issues that can be thought of when it comes to both wild shrimp catching and fish farming. When catching wild shrimp, many fishers like to overfish. This can cause shrimp population levels to drop, and cause them to become endangered. There are also parasites, such as tapeworms in brine shrimp, which turn them bright red and make them very easy prey for bird species and such, and Orthione griffenis, better known as Griffen's isopod, which is a small isopod that attaches to a shrimp's gills and sucks the life out of them. Not only are these revolting, they're causing shrimp species to plummet.
Fish farming is known of, and is a very profitable business. However, there are many concerns that can arise. One of these concerns is unethical treatment of the fish. Some farmers may starve or overfeed their fish, meanwhile others may overbreed them. There's also concerns of how the fish are acquired. If fish are taken from the wild to be farmed, some may see this as cruel or inhumane. Quality of life for the fish is a large concern, as if a fish is unhappy or ill, it can cause the consumer to fall ill from the product, which wound cause trouble for many.
There are many more issues that could arise, but overall, these are some of the most major issues when it comes to shrimp catching and fish farming.
This laboratory setup would most likely be used to demonstrate
carbohydrate synthesis
active transport
dehydration
diffusion
Answer:
I think it’s active transport
The laboratory setup would most likely be used to demonstrate the process of diffusion.
What do you mean by Laboratory?A Laboratory may be defined as a place where a variety of experiments may be performed depending on the work or projects it handles.
In this experiment, an artificial cell containing glucose and starch solution is dipped into the water containing a starch indicator.
The concentration of glucose or starch is found to be high in the artificial cell, hence, it removes the water or particles from the inside to the outside of the cell.
Diffusion may be defined as the movement of particles or matter from a region of high concentration to a region of low concentration.
Therefore, the laboratory setup would most likely be used to demonstrate the process of diffusion.

Pros of Biofuel
Pleas help it’s urgent
Answer:
Pros of Biofuels
Renewable – Biofuels are produced from plants and other organic material, so it can be replenished constantly. This is in contrast to the fossil fuels, which are constantly in the process of being depleted.
Clean – Biofuels are environment-friendly. They are much efficient & cleaner than fossil fuels, producing less air pollution and using materials that would otherwise be considered as waste products. Biofuels cause much less greenhouse gas emissions in comparison to the conventional types of transport fuels.
Inexpensive – They can be made easily by using local materials. Biofuels are very cheap to afford. They are the cheapest types of fuels available in the world.
Flexible – can be easily mixed with other fuels.
Additives – Biofuels like ethanol and biodiesel are better for car engines than fossil fuels. Even if not being used as the main fuel source, they can be used as additives to improve performance.
Carbon neutral – the amount of carbon dioxide created by the burning of biofuels is equal to the CO2 absorption capacity of the plants. Hence, no extra CO2 remains in the atmosphere.
Explanation:
Animals' bodies get some carbon atoms from
air.
True or false
Explanation:
It gives off carbon. So false.
You have been provided with a non-polar liquid and are trying to determine whether
it is hydrophilic or hydrophobic. You place one milliliter of the substance into a
beaker filled halfway with water. Describe what will happen next.
Answer:
Explanation:
Non-polar liquids are liquids that have covalent bonds in which the shared electrons are shared equally. The molecules of these liquids are repelled by the molecules of water and hence do not dissolve in water. Thus, non-polar liquid are hydrophobic (water dislike/insoluble in water).
When one milliliter of the substance is placed into a beaker filled halfway with water, the substance will be seen "compact" (not dissolving nor interacting) in the beaker of water.
Polarity is defined as the separation of electric charge in a molecule or having an electric dipole moment due to the difference between negative and positively charged ends.
In the given experiment when one milliliter of the substance into a beaker is filled halfway with water, the substance will be seen as coagulating or not dissolving in the water.
The non-polar are the compounds or liquids that do not dissolve in the water. The non-polar molecules are the molecules, which are attracted to the alike molecules, rather than the water molecules.
The non-polar compounds have covalent bonds, in which the electrons are shared among the atoms of the compound.
The molecules of these liquids are repelled in the presence of water or are hydrophobic. These liquids do not dissolve in water.
Therefore, the liquid is hydrophobic.
