The hypoxic zone in the Gulf of Mexico is not unique; at least 200 dead zones exist at estuaries and along seacoasts worldwide. These low-oxygen regions share many of the same causes, and they all have ecological and economic repercussions for ecosystems and people. Fortunately, we can pursue strategies to lessen the number, severity, and impacts of dead zones. The following list includes examples of factors that contribute to the development of dead zones (the cause), the consequences that result from dead zones, and possible solutions. Which of the following are consequences of dead zones?
a. Economic losses for fisher's
b. Death or aquatic organism that cannot escape
c. Policies to promote no-till agriculture
d. Construction of wetlands to absorb nutrients
e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition
Answer:
Answer:
e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition
Answer:
Explanation:
Run off from agricultural wastes which contain Nitrogen and Phosphorus are the major sources causes dead zones.The process where these chemical get washed into the aquatic bodies is called Eutrophication.
These substances leads to algae boosts in the water.The increases population of the algae consumes the available oxygen in the water, therefore making the oxygen concentration drops or no oxygen at all;(Hypoxia)
As the algae population feed on the available resources in the water they exhausted this,and later die.
When the decomposing bacteria used the oxygen in the water to breakdown the dead algae they make use of the available oxygen.This further reduced the oxygen availability and therefore reduces the oxygen and hence the zone becomes the dead zone, because little or no oxygen is available for survival of organisms.
This is reversible if the process if europhication or other causes is eliminated

All of the following events occur during prophase in mitosis except
WILL MARK BRAINLIEST
A. Condensation of DNA
B. Crossing over
C. Pairing of chromosomes
D. Spindle formation
All of the following events occur during prophase in mitosis except crossing over (Option B)
Mitosis can be divided into four phases: prophase, metaphase, anaphase, and telophase.During prophase, the chromatids condense into chromosomes, thereby making them visible. The mitotic spindle is a structure composed of microtubule proteins that segregate the chromosomes in mitosis. This structure is formed in prophase.In Prophase homologous pairs of chromosomes are paired together. In metaphase, these chromosomes are lined up at the equator of the cell and sister chromatids are attached to the spindle fiber.Crossing over (or recombination) is the exchange of genetic material between non-sister chromatids that occurs during prophase I of meiosis.In conclusion, condensation of DNA, the pairing of chromosomes and, spindle formation occur during prophase, whereas crossing over occurs in prophase I of meiotic cell division (Option B).

Explanation:
Both strands of the DNA double helix contain nitrogenous bases held together by hydrogen bonds. In DNA, the sequence of nitrogenous bases varies widely. What is the significance of the nitrogenous bases?
A. They determine the amino acids in the proteins synthesized.
B. They prevent mutations from occurring in the process of DNA replication
C. They help complete the sugar-phosphate backbone of DNA molecules.
D. The amount of adenine and cytosine determines the length of the gene on a DNA molecule.
Answer:
A
Explanation:
Essentially, in the process of protein synthesis, there is first transcription where mRNA is synthesized off of a DNA strand with complementary nitrogenous bases. After processing occurs (in basic terms the mRNA is literally processed) and the mRNA strand leaves the nucleus, it attaches to a large and small ribosomal subunit (a ribosome) where translation occurs. The gist of it is when the mRNA strand is being read by the ribosome. tRNA will come over and bind temporarily bringing with it a specific amino acid, starting the formation of the polypeptide/amino acid chain. Nitrogenous bases play into this as the sequence of the nitrogenous bases is what determines what tRNA will bind onto it which determines which amino acid is brought. More specifically, this deals with the codons of the mRNA and the corresponding anticodons with the tRNA, which is a bit of a more specific topic.
The nitrogenous bases help complete the sugar-phosphate backbone of DNA molecules. The correct option is C.
What is DNA?DNA, also renowned as deoxyribonucleic acid, is a complex molecule that includes all of the information required to construct and retain a lifeform.
DNA is found in the cells of all living things. In real sense, as in almost every cell in a multicellular organism contains the entirety of the organism's DNA.
DNA is composed of chemical key components known as nucleotides. These building blocks are composed of three components: a phosphate group, a sugar group, and one of four different types of nitrogen bases.
Nucleotides are linked together in chains, with the phosphate and sugar groups alternating.
Thus, the correct option is C.

O intertidal, deep, surface
O neritic, intertidal, open ocean
O open ocean, deep, continental
Answer:
Honestly I think it's C
Explanation:
The three main ocean zones are neritic, bathyal, and abyssal. Therefore, none of the statements are correct.
What are the three main zones?The ocean is divided into three main zones which are the neritic zone. This zone is the shallowest zone extending from the shoreline to the edge of the continental shelf and is 200 meters deep.
The bathyal zone is the middle zone extending from the edge of the continental shelf to the abyssal plain and is 4,000 meters deep. The abyssal zone is the deepest zone extending from the abyssal plain to the ocean floor.
Apart from the three main ocean zones, there other oceanic zones are epipelagic zone, mesopelagic zone, and hadal zone. The hadal zone is the deepest oceanic zone and is unique to highly adapted species of marine life and is important to study.
Therefore, the three main ocean zones are neritic, bathyal, and abyssal.

Explanation:
When the isotonic saline solution described in part A is connected to an unknown solution via a semipermeable membrane, the unknown solution level drops. Based on this information, what can be said about these two solutions?
Answer:
The new solution has a higher concentration than the isotonic saline solution
Explanation:
Here, we want to deduce what has happened in the question.
We are told that the level of the isotonic saline solution dropped because it was connected an unknown solution using a semipermeable membrane.
Since the level of the solution dropped, then it must have occurred that there has been the loss of some of the molecules of the solution.
What has occurred is the process of Osmosis
Osmosis simply involves a movement through a semipermeable membrane of solvent molecules due to the fact that the previous solution is of lower concentration than the present one.
So what we can see here is that there has been a movement due to osmosis as a result of the fact that the new solution has a higher concentration than the former one

Based on the data in the graph, how are cyanobacteria responsible for the rise in atmospheric oxygen? State your claim, then make sure to use evidence from biological processes and data from the graph to support your claim.
Answer:
They perform photosynthesis, releasing oxygen into the atmosphere as a by-product.
Explanation:
Around the time that cyanobacteria appear around 3.2 billion years ago, the oxygen levels rise sharply.
Cyanobacteria are photosynthetic organisms. They possess the photosynthetic pigment chlorophyll, meaning they can trap light energy and use it to power chemical reactions to synthesise glucose. They convert carbon dioxide and water into sugar, releasing oxygen into the atmosphere as a byproduct. This causes oxygen levels to rise.
Answer:
Cyanobacteria are microbes that live primarily in seawater. They are believed to have been the first organisms on Earth to perform oxygenic photosynthesis. In this process, they produce organic carbon, the building blocks of life's molecules, and release oxygen gas (O2).As oxygen photosynthesis starts,that's when the first O2 producing of cyanobacteria occurs.The graph reaches a peak at Cambrian explosion.
