Fish that can survive the lower oxygen levels undergo natural selection. These fish will reproduce and proliferate.
The water's lower oxygen levels will impact fish respiration. The fish may relocate to a better area with more dissolved oxygen in order to adapt to the change. However, because the fish are still the same genetically and phenotypically, there is no connection to the process of natural selection. Fish that can survive the reduced oxygen levels are selected naturally. These fish will reproduce and multiply in quantity. Fish from the next generation will be tolerant of decreased oxygen levels. This novel phenotypic denotes a modification in the genetic makeup of the fishes.

A deficiency in what trace mineral is associated with loss of taste, poor wound healing, and cessation of spermatogenesis?.
Zinc deficiency is linked to taste loss, poor wound healing, and the cessation of spermatogenesis.
What are the signs and symptoms of a zinc deficiency?Zinc deficiency occurs when the body does not have enough zinc. During pregnancy, childhood, and adolescence, zinc is essential for the immune system, wound healing, and proper growth and development. Zinc deficiency can cause initial skin changes that resemble eczema.The skin frequently develops cracks and a glazed appearance, particularly around the lips, diaper area, and hands. Lotions, steroid creams, and moisturizers have no effect on the rash.Some people cannot get enough zinc through diet alone. Because protein aids in zinc absorption, vegetarians and vegans, as well as those on long-term restricted diets, may be more vulnerable. Children on restricted diets and infants breastfed exclusively for more than six months are at risk of zinc deficiency.To learn more about zinc deficiency, refer to:

if extinctions are generally a result of changes in the environment that a species is unable to adapt to, what do you think this indicates about the 5 previous mass extinctions and the 6th one occurring now? how long does it typically take for biodiversity to "recover" after a mass extinction?
Answer:
This indicates that extinctions can be both naturally-caused, such as by collapse in food chains due to a large meteorite striking the Earth, and human-caused, including habitat destruction, overharvesting, introductions of invasive species, climate change, and emerging diseases. Because much of the current environmental change caused by human activities is dramatic and sudden, many species may not be able to move or put in the time to avoid extinction. And, the recovery of biodiversity from previous mass extinctions took about 10 million years. The recovery from the present mass exitinction could take just as long-- 500,000 human generations.

What are the first three amino acids coded by this new mutated sequence
The first three amino acids coded by this new mutated sequence are Glutamine, Alanine, and Lysine.
One triplet nucleotide is coded for by one amino acid. Therefore, there are 16 nucleotides altogether following the insertion of the adenosine residue. The mRNA sequence will thus encode five amino acids. A codon is a collection of three nucleotides that are found in mRNA, and each codon designates an individual amino acid (hence, it is a triplet code). Thus, the chain of amino acids that makes up a protein is assembled in accordance with the template provided by the mRNA sequence and this is how Glutamine, Alanine, and Lycine form.
A gene encodes the amino acid composition of a polypeptide. The polypeptide's amino acid composition is determined by the bases in the gene's DNA. Proteins can either have a single polypeptide or many polypeptides linked together. All of a cell's or an organism's generated proteins are found in the proteome. A codon is a group of three DNA or RNA nucleotides that specify an amino acid or serve as a signal to cease protein production.

Compare and contrast semidiurnal tides, mixed semidiurnal tides and diurnal tides.
It is called a semi-daily or semidiurnal tidal pattern when the heights of the two highs and lows are roughly equal whereas a mixed semidiurnal tidal pattern is one in which the heights of the high and low tides vary. It is called a diurnal tide when areas have only one high and one low tide each day.
Since "diurnal" refers to a daily occurrence, a tide is said to be diurnal if there is just one whole tidal cycle every day. In the Gulf of Mexico, on Alaska's west coast, and in some regions of Southeast Asia, diurnal tides are typical.
Semidiurnal refers to "half of a day," and as one tidal cycle lasts for half a day, there are two full cycles per day. The majority of Europe, the west coast of Africa, the east coast of North America, and Australia all experience semi-daily tides.

When animals and plants die, decomposers return the carbon locked in their bodies back to the atmosphere via ________
When animals and plants die, decomposers return the carbon locked in their bodies back to the atmosphere via respiration.
What is meant by Decomposers?Decomposers may be characterized as a type of organism that significantly breaks down dead organic material. These organisms are essential for maintaining the balance on the earth's surface. These micro-organisms digest things that are dead or decaying and turn the dead plants and animals into humus.
Animals that eat plants digest the sugar molecules to get energy for their bodies. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle. The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere.

Following are the possible effects of Water contamination
Germs and contaminants can contaminate drinking water at the source or in the distribution system after the water has been treated. Some of the sources through which dangerous bacteria and chemicals could infiltrate rivers include fertilizers, pesticides, or other chemicals that have been used to treat land close to waterways.
Dangerous microorganisms that may be present in contaminated water include the following:
GiardiaSalmonellaCrypstosporidiumEcoliLegionellaThe spread of diseases like cholera, diarrhea, dysentery, hepatitis A, typhoid, and polio is only one of the problems that contaminated water and poor sanitation may cause. People face avoidable health risks when water and sanitation facilities are insufficient, poorly managed, or unavailable.
Drinking contaminated water can expose one to bacterial, viral, and protozoal illnesses.
Many of these are pathogens, which after consumption can swiftly send a person to the hospital.

The right reason to why the P waves and S waves are not received in the shadow zone is because P waves are refracted and S waves are absorbed in the earth's outer core.
As they move further into the Earth's mantle, P waves and S waves move faster.
Curvilinear pathways are followed as they move through the Earth, but when they cross the barrier between substances in various states, they abruptly shift course.
However, P waves can go through the liquid outer core but S waves cannot. Because of the Earth's changing density, waves are refracted as they pass through it. As a result, the waves follow curved pathways. Refraction causes an abrupt shift in direction of the waves when they cross the boundary between two separate layers.
What are the differences between P waves and S waves?
P waves can pass through solids, liquids, and gases, but S waves can only pass through solids. The structure of Earth can be determined by scientists using this information. Seismometers all across the world can measure the ensuing S and P waves, for instance, if an earthquake happens on one side of the Earth.

Which term describes a mutation where a chromosome breaks, and its genetic material is reinserted in a different orientation?.
Chromosomal Inversions: An inversion occurs when a chromosome breaks in two places; the resulting piece of DNA is reversed and re-inserted into the chromosome. Genetic material may or may not be lost as a result of chromosome breaks.
Inversion happens when a part of the chromosome breaks off, turn around, and becomes reaffixed. So, the order of the genes becomes reversed from what it was. While most cases of inversions go unnoticed and cause no gains or losses of DNA, they can lead to infertility or phenotypic reverberation.
An inversion can disrupt a gene, either by truncating the coding region of the gene or by placing its regulatory region far from the gene itself.
There are two kinds of Inversion mutation:
Pericentric Inversions- It happens when the centromere is included in the break. In other words, the break happens in the centre of the chromosome.
Paracentric Inversions- These occur when a chromosome breaks in one of its arms. In other words, the centromere is not incorporated.
