Answer:
Una mutación es el cambio al azar en la secuencia de nucleótidos o en la organización del ADN (genotipo) de un ser vivo,1 que produce una variación en las características de este y que no necesariamente se transmite a la descendencia. Se presenta de manera espontánea y súbita o por la acción de mutágenos. Este cambio estará presente en una pequeña proporción de la población (variante) o del organismo (mutación). La unidad genética capaz de mutar es el gen, la unidad de información hereditaria que forma parte del ADN.2
En los seres pluricelulares, las mutaciones solo pueden ser heredadas cuando afectan a las células reproductivas.3 Una consecuencia de las mutaciones puede ser, por ejemplo, una enfermedad genética. Sin embargo, aunque a corto plazo pueden parecer perjudiciales, las mutaciones son esenciales para nuestra existencia a largo plazo. Sin mutación no habría cambio, y sin cambio la vida no podría evolucionar.

What are some ways that the nitrogen cycle overlaps with or influences the oxygen and carbon cycles?
Are any of these interactions between the cycles positive?
Are any negative?
What about when the nitrogen cycle is thrown off balance by the Haber-Bosch process and others like it?
How can that influence the oxygen and carbon cycles?
Are there other cycles involved that have not been mentioned in this question?
What does this discussion suggest about the nature of the Earth as one large system?
Answer:
1. Nitrification occurs when soil microbes convert ammonium into nitrate. Much of the overlap between the carbon cycle and the nitrogen cycle occurs in the soil, in processes conducted by soil microbes. Microbes break down nutrients, build new compounds for their own growth, and eventually die.
The second question im not sure sorry- the positive and negative one ;(
3. Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem. As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.
4. Carbon makes its way through living things as carbon-based compounds, like energy molecules, fats and proteins, eventually cycling its way back into the atmosphere. Nitrogen is mainly found in the atmosphere as well and enters the ecosystems as nutrients for plants. Water, nitrogen and carbon cycles. Carbon moves from the atmosphere and back via animals and plants. Nitrogen moves from the atmosphere and back via organisms. Water moves on, above, or below the surface of the Earth.
5. Carbon cycle, Nitrogen cycle, Nutrient cycle, Oxygen cycle, Phosphorus cycle, Sulfur cycle, Rock cycle, Water cycle.
6. Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth's plates slowly reconfigures oceans and continents. Each one of these processes plays a role in the Arctic and Antarctica.
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Earth's surface is the only habitat available to the human race. Understanding the processes by which that habitat has been created and continually altered is important to determine the causes of environmental degradation.
which statement best describes how genes are able to produce a organism's traits? A. Genes have versions called alleles, which produce different traits. B. Genes exit the nucleus and go to ribosomes, where proteins form. C. Genes contain codes that specify proteins, which produce traits. D. Genes unwind and become templates, where amino acids can line up.
Answer:
C
Explanation:
The genes contain codes that specify proteins, which produce traits.
Genes contain codes that specify proteins, which produce traits best describes how genes are able to produce a organism's traits.
What is a gene?Genes are segments of DNA that contain the instructions for making proteins, which are complex molecules that perform a wide variety of functions in the body. Proteins are made up of chains of amino acids, and the specific sequence of these amino acids is determined by the code contained in a gene. Different versions of a gene, called alleles, can produce different sequences of amino acids and therefore different proteins, which can lead to different traits in an organism.
Genes are found in the nucleus of cells, and the process of making proteins begins when a gene is transcribed into a molecule called RNA. This RNA molecule exits the nucleus and goes to ribosomes, which are the site of protein synthesis. At the ribosomes, the RNA molecule serves as a template for the synthesis of a protein, with the specific sequence of amino acids being determined by the code contained in the RNA molecule. The protein is then folded into its characteristic shape, which allows it to perform its specific function in the body.

not fight
Explanation:
you should try to restrain from fighting there will always be a consiquence. whether you know it or not.

If the person has sinned against you, forgive them. if you just want to fight for some unknown reason, pray for help from God.

A. An experience or period in the author’s life.
Explanation:
A memoir is a story about an experience in someones life, but it has to be factual. A memoir can not be based on fiction, it has to be real and nonfictional.
Memoirs are usually told in first person, as it is recounting the occurrences that happened in ones life. It is different from an autobiography, as autobiographies usually focus on the whole lifespan of a person, while a memoir focuses on one topic or event that happened.
Memoirs also usually focus on personal growth throughout the writing, are truthful and keep track of the persons goals and influences.

Which is a leading theory for the formation of fossil fuels?
Answer:
The most generally accepted explanation for fossil fuel production is that, over time, fossil fuel was formed from declining organic matter. Organisms died and were buried in the earth millions of years ago. The carbonaceous substances within the humans, subjected to the high temperature and pressure below the earth's surface, were converted into types of fossil fuel such as coal and oil.

For children who do not have galactosemia, what are their possible genotypes for this trait?
a pedigree chart for the inherited genetic condition galactosemia
heterozygous
homozygous dominant
homozygous recessive
no inheritance for this trait
Answer:
The correct answers are "heterozygous", and "homozygous dominant".
Explanation:
Galactosemia is a condition where people are not able to process the sugar galactose. People with this condition have one gene mutated, which does not allow the proper synthesis of the enzyme that breaks down galactose. Galactosemia is inherited as an autosomal recessive genetic condition, therefore, only children that are homozygous recessive develop the condition. Children that are heterozygous or homozygous dominant, will not develop galactosemia.
Answer:
its heterozygous and homozygous dominant
