Answer:
to decompose organic matter
Explanation:
Answer:
Decomposers feed on dead things: dead plant materials such as leaf litter and wood, animal carcasses, and feces. They perform a valuable service as Earth's cleanup crew. Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere.
What canwe do to decrease our disruption of the nitrogen Cycle?
Answer:
We can use less pollutants.
Explanation:
Gracias a una investigación internacional se ha averiguado que las actividades humanas causan estragos en los bosques tropicales al alterar el ciclo de nitrógeno normal. Los descubrimientos, publicados en Science, proporcionaron las primeras pruebas de efectos a largo plazo por contaminación de nitrógeno en árboles tropicales. Los científicos, de Austria, Canadá, Alemania y Panamá, trabajaron en dos emplazamientos remotos del Observatorio Terrestre Global del Instituto Smithsonian en Panamá y Tailandia. «La contaminación atmosférica fertiliza los bosques con uno de los nutrientes más importantes para el crecimiento», afirmó S. Joseph Wright del Instituto Smithsonian de Investigación Tropical en Panamá. «Comparamos el nitrógeno que contenían hojas de especímenes secos recogidas en 1968 con el de muestras de hojas de 2007. La concentración de nitrógeno foliar y la proporción de isótopos de nitrógeno tanto pesados como ligeros ha aumentado en los últimos 40 años del mismo modo a como lo hicieron en un experimento anterior en el que se abonó el suelo del bosque. » El nitrógeno se origina en el interior de las estrellas gracias a temperatura y presión elevadas. En condiciones normales es incoloro, insípido e inodoro, y poco propenso a reaccionar con otras sustancias. En la atmósfera flota más del 75% del nitrógeno, que además es un componente esencial de las proteínas. Uno de los cambios que «activan» el nitrógeno viene producido por ciertas bacterias colonizadoras de raíces vegetales que extraen nitrógeno de la atmósfera y lo que significa o fijan en una forma útil para el crecimiento vegetal. Cuando las bacterias ya no necesitan el nitrógeno la planta lo absorbe, para luego pasar a los animales. La fijación del nitrógeno se define mediante el proceso de Haber, que convierte el proceso de nitrógeno gaseoso en amoníaco, un ingrediente común en los abonos. La fijación de nitrógeno por medios artificiales ha aumentado la cantidad de emisiones de nitrógeno reactivo en un 100%. Según los investigadores, el nitrógeno presenta dos formas o isótopos, átomos con la misma
Examples of reproductive advantage?
Answer:
Here are the advantages and disadvantages of sexual reproduction: 1. It creates a preserved and expanding effect. This method of reproduction will help preserve an existing genetic code of an allele to make sure that a certain species does not mutate, which is essential to its multiplication.

The female reproductive and endocrine systems work interactively for which main purpose?
Anwser:To control hormone levels to prepare the body for pregnancy
Explanation:
Uncle Smiley, who is heterozygous for a yellow face, married a woman with a green face. Both of them have always wanted a large family! If they were to have 12 children, how many of the 12 children would have yellow faces? How many of the 12 children would have green faces? Create a Punnett square to to help you find your answers. Hint: Yellow face is dominant to green face
Answer:
Since Yellow is dominant over green then almost all of the children will have yellow faces. The punnet square below will show what the offspring will have but my guess is
50% will have yellow faces
50% will have both yellow and green
1% will have a green face
But since Yellow is dominant over green the 50% of both colors will mostly show a yellow dominant.
I apologize if my drawing looks messy.

Scientists have concluded that Tiktaalik lived when deciduous trees began appearing on land, an event that occurred hundreds of millions of years ago. Which radiometric probe (Carbon-14, Iodine-129, Uranium-238) would you choose to determine a more accurate age of the Tiktaalik fossil? Explain your reasoning.
PLEASE HELP ME ILL GIVE 25 POINTS
Answer:
Carbon
Explanation:
Carbon leaves a bigger footprint when investigating fossils or skeletons scientists use carbon samples.
The Carbon-14 radiometric probe should be used to determine a more accurate age of the Tiktaalik fossil. Radiometric dating is the technique used to calculate the age of fossils.
What is radiometric dating?Radiometric dating or radioactive dating is a technique which is used to date the materials such as rocks or carbon, in which trace amounts of radioactive impurities were selectively incorporated when they were formed in the fossil such as trees.
Radiometric dating is used to calculate the age in years for a geologic material by measuring the presence of a short-life radioactive element in the fossil. For examples, carbon-14, or a long-life radioactive element plus its decay product which is potassium-14 or argon-40.

How many amino acids does this protein segment contain?
Answer: the given protein segment contains 20 amino acids
The given segment of the polypeptide chain is made up of four different types of amino acids, and each amino acid is connected to each other by the peptide bond, and the chain elongates from the N terminal to the C terminal.
What is the significance of amino acids?There are 20 different standard amino acids that take part in polypeptide chain synthesis, and those are categorized into some particular types such as hydrophobic amino acids, hydrophilic amino acids, charged and uncharged amino acids, etc., and different compositions of the amino acids make different types of proteins. The polypeptide chain is generally synthesized from the N terminal to the C terminal, and here in the given diagram, there are four amino acids, and each amino acid has an amino group, a carboxylic group, a hydrogen group, and one side chain bonded to a single central carbon atom.
Hence, the given segment of the polypeptide chain is made up of four different types of amino acids.

How is cell differentiation different than mitosis?
Answer:Cell differentiation is the process by which cells specialize to achieve their required functions. In order for a cell to differentiate, it will express specific genes. mitosis produces cells that are identical to each other (clones).
Explanation:
Answer:
Though the options aren't presented to the question, I believe the correct answer is: Cell differentiation is different than mitosis, for during cell differentiation, it produces cells with different gene expressions. Meanwhile, during mitosis, it produces clones of the same genes.

what will happen to the concentrations of ATP,NADPH, and sugar when you add paraquat
Answer:
Increase ATP
Decrease NADPH
Decrease Sugar
Concentrations of ATP, NADPH, and sugar decreases when we apply paraquat on the plants.
The concentrations of ATP,NADPH, and sugar decreases when you add paraquat because paraquat is a toxic chemical which blocks the activity of respiration in plants leading death of those plants. Paraquat inhibits the ATPase activity which is responsible for the production of ATP.
So due to no cellular respiration no ATP is produced. Paraquat (PQ) also inhibit photosynthesis so no glucose as well as NADPH is produced so we can conclude that concentrations of ATP, NADPH, and sugar decreases when we apply paraquat on the plants.
