Answer:

A) overfishing in previous years and warm waters with few nutrients

Explanation:

Under El Niño conditions, there is a tropical stream, which is usually weak, that acquires strength while the opposite streams debilitate. This event impedes warm water to go eastward, remaining in South America´s coasts, which produces unusual precipitations in Chile followed by floral bloom in Atacama desert and fewer precipitations events in Eastsouth Asia and North Australia. During and after the El Niño, occurs a fishery crisis because there is no upwelling on the coasts of South America, nutrients from the bottom do no ascend, and fish populations remain equal or decrease.    

Around 1970, there was excessive overexploitation of fishes. This overfishing probably led to a significant decrease in the anchovy population size, reducing the number of individuals in the reproductive stage, especially the females. The graph reflects that during the following years, there were also peaks in anchovy catch. The population did not have enough time to recover from the highest peak in 1970.

From 1982-1983 El Niño event was severe. No upwelling meant no nutrients to survive, and that the remaining anchovy population, previously affected by fishery, hardly made it that year. There was probably a fishery crisis, and hence, no animals were caught in 1984.

In the liver, the amine group of glutamic acid is removed as ammonia in the oxidative state.

This process is known as deamination and is catalyzed by the enzyme glutamate dehydrogenase. Glutamic acid is an amino acid that is involved in many metabolic processes in the body. It is a non-essential amino acid, meaning that the body can synthesize it on its own. Glutamic acid is an important component of proteins and is also a precursor to other amino acids, such as arginine and proline. The process of deamination of glutamic acid produces ammonia, which is toxic to the body in high concentrations. The liver converts ammonia into urea, which is excreted in the urine. This process is known as the urea cycle and is an important mechanism for the detoxification of ammonia in the body.

Explanation:

The island population of finches most likely developed adaptations such as a larger and stronger beak to efficiently consume the small, hard seeds produced by the trees.

In response to the different environment on the island, the finches likely underwent natural selection favoring traits that allowed them to effectively obtain food from the available resources. With the abundance of small, hard seeds produced by the trees, the finches with larger and stronger beaks would have had an advantage in cracking open and accessing the seeds. Over time, individuals with traits that allowed them to exploit the available food source would have been more successful in survival and reproduction, leading to the increase in the frequency of these adaptive traits within the population.

This process is an example of adaptive radiation, where a population of organisms diversifies and adapts to different ecological niches. In this case, the island population of finches experienced a selective pressure favoring traits that facilitated feeding on the small, hard seeds. Through natural selection, the beak size and strength likely evolved to better suit the new food source, allowing the finches to survive and reproduce more successfully on the island.

The DNA of telomeres has been found to be highly conserved throughout the evolution of eukaryotes reflecting that the critical function of telomeres must be maintained.

Genome protection from nucleolytic degradation, unnecessary recombination, repair, and interchromosomal fusion are provided by the specific DNA–protein structures known as telomeres. They are found at both ends of each chromosome. As a result, telomeres are crucial to the preservation of our genome's information.

With age, telomere length decreases. Somatic cells undergo senescence, apoptosis, or oncogenic transformation as a result of telomere shortening over time, which has an impact on a person's health and lifespan. Shorter telomeres have been linked to lower survival rates and an increased risk of disease. Lifestyle choices can either speed up or slow down the rate of telomere shortening.

what is Gout attack?

Anyone can develop gout, a common and complicated form of arthritis. It is characterized by frequent big toe pain and sudden, acute bouts of swelling, redness, and soreness in one or more joints.

Gout attacks can come on abruptly, frequently causing you to wake up in the middle of the night feeling as though your big toe is on fire. Even the weight of the bedsheet may appear unpleasant on the affected joint because it is so hot, swollen, and sensitive.

Uric acid, which causes gout, is a byproduct of purine metabolism, which is produced when nucleic acids (DNA and RNA) and ATP are broken down. Uric acid can also be produced from proteins.

Answer:

Increases the concentration of carbondioxide gas in the atmosphere.

Explanation:

The burning of fossil fuel increases the concentration of carbondioxide gas in the atmosphere because when the fossil fuel burns, carbondioxide gas is released. Carbondioxide gas is a greenhouse gas which goes up in the atmosphere and make a layer which allow light radiation to the earth but prevent it from going to the space after reflection which causes increase of surface temperature of the earth leads to global warming.

The fossil fuel combustion has increased the concentration of carbon atoms in the atmosphere.

Concentration of carbon means the amount of carbon in the atmosphere.

The amount of carbon dioxide has increased substantially after the industrial era.

The concentration of carbon is 400 parts per million in more traffic areas.

The level of indoor carbon depends upon the number of person present there.

Thus, the fossil fuel combustion has increased the concentration of carbon atoms in the atmosphere.

Explanation:

Prokaryotic initiator tRNA is unusual in that it is smaller than its eukaryotic counterpart and is missing the variable arm loop found in other tRNA molecules.

The initiator tRNA in prokaryotes is unusual because it carries a modified form of the amino acid methionine, called N-formylmethionine (fMet). This modified amino acid is used to initiate protein synthesis in prokaryotes, whereas in eukaryotes, the initiator tRNA carries unmodified methionine. Additionally, the initiator tRNA in prokaryotes has a different anticodon sequence (CAU) than the initiator tRNA in eukaryotes (UAC). This allows for the specific recognition and binding of the initiator tRNA to the start codon (AUG) in prokaryotes.

There are many things that can be read from ripple marks in sedimentary rocks. To start, a geologist looks at: the types (sizes, composition, shapes) of grains in the rock, the height of the “waves”, the distance between peaks (highs) and troughs (lows), whether the rock seems to be lying in its original position, and the internal shapes of the ripples (by looking at the edges of broken pieces). They also seek to determine the age of the rock and information about other rocks lying below and above the specific rock.

Although multicellular organisms exhibit a division of labor and tissue specialization, each cell still needs to produce its own ATP.

The number of cells in multicellular organisms ranges from millions to trillions. These cells all carry out distinct tasks. In the body, tissues are made up of all the cells that have been trained to carry out certain tasks. Thus, a set of cells at a specific location in the body perform a specific function. Similar to how distinct functions are carried out by several groups of cells inside an organism, multicellular organisms have a division of labor.

ATP is created when energy from storage molecules is required by the cell. Then, ATP acts as a shuttle, transporting energy to regions of the cell where energy-intensive processes are occurring. The net result of every cellular electron transfer involving ATP is the synthesis of ATP molecules.

Answer:

Antibiotics, also known as antimicrobial drugs, are drugs that fight infections caused by bacteria. Alexander Fleming discovered the first antibiotic, penicillin, in 1927. After the first use of antibiotics in the 1940s, they transformed medical care and dramatically reduced illness and death from infectious diseases.

The term "antibiotic" originally referred to a natural compound produced by a fungus or another microorganism that kills bacteria which cause disease in humans or animals. Some antibiotics may be synthetic compounds (not produced by microorganisms) that can also kill or inhibit the growth of microbes. Technically, the term "antimicrobial agent" refers to both natural and synthetic compounds; however, many people use the word "antibiotic" to refer to both. Although antibiotics have many beneficial effects, their use has contributed to the problem of antibiotic resistance.

Antibiotic resistance is the ability of bacteria or other microbes to resist the effects of an antibiotic. Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply causing more harm.

Based on the climograph, the primary difference between temperate grasslands and temperate broadleaf forests is that temperate broadleaf forests receive more precipitation.

A climograph is a graphical representation of the precipitation and temperature patterns in a specific area. When comparing the climographs of temperate grasslands and temperate broadleaf forests, we can see that both have similar temperature ranges.

However, the precipitation levels are notably different. Temperate grasslands have lower precipitation levels throughout the year, while temperate broadleaf forests experience higher levels of precipitation, supporting a more diverse and dense vegetation.
The key factor that differentiates temperate grasslands from temperate broadleaf forests, based on the climograph, is the amount of precipitation they receive, with temperate broadleaf forests receiving more precipitation than temperate grasslands.

The answer is option B.

Hope this helps you

Explanation:

Terrestrial biomes are distinguished primarily by their predominant vegetation, and are mainly determined by temperature and rainfall. Differences in temperature or precipitation determine the types of plants that grow in a given area . Regions of similar climate and dominant plant types are called biomes.

Climate is the major factor affecting the number and diversity of plants that can grow in a terrestrial biome. Climate determines the average temperature and precipitation, the length of the growing season, and the quality of the soil, including levels of soil nutrients.

The primary factor which determines a biome is the climate. Temperature and precipitation essentially determines what kind of growing season or soil quality the terrain may have,which therefore affects the growth of plants living there.

A mutation in the gene that codes for the KIT receptor protein can change the structure of this protein due to the substitution of an amino acid by another, which may alter its physicochemical properties (question 1). The amino acid sequence that becomes the KIT Receptor Protein may change due to the presence of non-synonym mutations (question 2). The structure of the KIT Receptor Protein may also vary due to a conformational change (question 3), while this change may alter the solubility of the protein or avoid the exposure of the active site in physiological conditions (question 4).

The amino acid chain in the resulting protein encoded by a gene that suffered from a mutation may be affected if the change produces a non-synonym codon that is encoded for another amino acid. This process is well known to produce changes in the tridimensional conformation of proteins as well as their physical-chemical properties in solution

Therefore, with this data, we can see that the amino acid chain in the resulting protein after mutations may be altered and therefore influence the conformation and properties of the protein.
