Carbon 12 is the most common isotope of carbon with a mass number of 12. However, the average atomic mass of carbon found on the periodic table is more than 12 tons. This is because of the following reasons: The tom does not include the mass of electrons.

This is because electrons are much lighter than the other subatomic particles, and their mass is not considered in the calculation of the atomic mass of an element. Some carbon stores in uwe have an extra proto. Carbon 12 is the most abundant isotope of carbon and has six protons and six neutrons in its nucleus. However, some carbon atoms have an extra neutron or two, making them isotopes of carbon. The presence of these isotopes in nature accounts for the slightly higher atomic mass of carbon found on the periodic table.

DNA does not play a role in translation. The correct answer is the fifth option.

The translation is the process by which protein is synthesized. During this process, the mRNA first binds to the small unit of the ribosome.

After this, the tRNA will read the first code (start codon) in the mRNA and brings the first amino acid. These form the initiation complex.

As this complex moves along the mRNA, the tRNA read the codons in mRNA using its anticodon and brings the appropriate amino acids. These amino acids form peptide bonds between them.

Once the complex reaches the stop codon, the protein synthesis stops. Here, there is no direct involvement of DNA in the translation process.

1. Time taken by Gary and Diane to complete the garden if they divide the soil preparation equally and the planting equally is 32 hours.

2. Time taken by the two to complete the garden if they use comparative advantage and specialize in soil preparation or planting is 34 hours.

1. To calculate the time taken by Gary and Diane to complete the garden, let's write the time taken by Gary to prepare the soil to be x hours. So, the time taken by Diane to prepare the soil will also be x hours. As given, Diane can plant 100 flowers in 12 hours. Thus, Diane can plant 25 flowers in 3 hours. Therefore, the time is taken by Diane to plant 100 flowers

= (100/25) × 3 = 12 hours.

Now, the time taken by Gary to plant 100 flowers will also be 12 hours. Therefore,

total time taken by both Gary and Diane to complete the garden = Time taken for soil preparation + Time taken for planting

= 2x + 12 hours = (2 × 10) + 12

= 32 hours

2.  To calculate the time taken by the two to complete the garden if they use comparative advantage and specialize in soil preparation or planting, we know that Diane can prepare the soil in 10 hours while Gary can prepare the soil in 20 hours. Therefore, Diane should prepare the soil. Now, the time is taken by Diane to prepare the soil = 10 hours. Diane can plant 100 flowers in 12 hours while Gary can plant 100 flowers in 24 hours. Therefore, Gary should plant the flowers.

Now, the time is taken Gary to plant the flowers = 24 hours. Therefore,

total time taken by both Gary and Diane to complete the garden = Time taken for soil preparation + Time taken for planting

= 10 + 24

= 34 hours

The genotype of the mother is XX, while that of the father is XY. If a non-disjunction occurred in an individual with the genotype XXX, it would occur in her mother since only from her mother could she acquire two Xs, but from her father, a non-disjunction would result in a XXY.

This non-disjunction occurred during meiosis I, when two copies of the same chromosome are transferred to separate cells. During this phase, the separation of these two chromosomes did not occur since they were both Xs from the mother brought together to the new haploid cell.

The non-disjunction on meiosis II simply indicates that two chromatids from a chromosome did not split and does not result in copies.

Explanation:

Researchers debate theories about the Triassic-Jurassic extinction event's origins, which include climate change, asteroid impacts, and volcanic eruptions.

The end-Triassic extinction was brought about by massive and extensive volcanic eruptions. Around 200 million years ago, an increase in atmospheric CO2 led to the oceans becoming more acidic and the Earth being warmer, which contributed to the extinction of 76% of marine and terrestrial species.

Extreme temperature variations, fluctuating sea levels, and catastrophic, one-time occurrences like a supervolcano erupting or an asteroid impacting Earth have all been responsible for previous mass extinctions. We are aware of them because the fossil record demonstrates how life has altered over time.

Additional functions of the cell wall include: Support: The cell wall provides mechanical strength and support.

It is important to follow the proper ELISA protocol and sequence of steps to ensure accurate and reliable results.

If the detection antibody was added first before immobilizing the protein sample, it would likely bind to any non-specific proteins or antigens present on the surface of the well. This could lead to false positives and inaccurate results as the detection antibody would not be able to specifically bind to the protein of interest.
In the ELISA procedure, immobilizing the protein sample first allows for the protein to specifically bind to the surface of the well and create a stable platform for subsequent antibody binding. This ensures that only the target protein is detected by the detection antibody and reduces the chances of false positives.
Therefore, it is important to follow the proper ELISA protocol and sequence of steps to ensure accurate and reliable results.

Answer:

First it helps them find food then it also helps them find shelter

Explanation:

Bunnies and things of that nature eat plants and plants use photosynthesis that is how they gain weight. Predators eat those animals and the bigger those animals are from eating plants the better the bunny or other animal is for the predator. Also it helps them find shelter because trees use photosynthesis and if trees grow big from that then animals have better pertection.

Animals depend on oxygen for survival, while plants purify the air by eliminating dangerous carbon dioxide helps a predator like a wolf or a tiger.

Light energy is used by organisms that employ photosynthesis to produce their own "food". In this procedure, carbohydrates and oxygen are produced using carbon dioxide and light.

This is excellent news for other creatures who use this oxygen and consume the plants. Because photosynthesis is the method used by plants to convert carbon dioxide into oxygen with the aid of sunlight, it is significant. It supplies practically all ecosystems with energy.

Therefore, plants, use photosynthesis to convert light energy into chemical energy, which is then consumed by the predator.

En el hemisferio sur el verano comienza en diciembre y finaliza en marzo, mientras que el invierno comienza en junio y finaliza en septiembre.

Perú se encuentra en el hemisferio sur, con lo cual el verano comienza el 21 de diciembre y finaliza el 21 de marzo, mientras que el invierno comienza el 21 de junio y termina el 21 de septiembre.

El afelio indica a la mayor distancia posible en la órbita de un planeta con respecto al Sol, mientras que el perihelio refiere a la menor distancia posible (es decir, el punto de mayor cercanía posible) entre la órbita de un planeta y el Sol. En la Tierra, el afelio se produce a comienzos de julio, donde nuestro planeta dista aproximadamente 152 millones de kilómetros con respecto del Sol, mientras que perihelio se produce a principios de enero, donde la Tierra dista aproximadamente 147 millones de kilómetros con respecto del Sol.

La caída de lluvia es un fenómeno independiente a la estación del año, es decir, la lluvia caída en enero o julio no modifica que en el hemisferio sur nos encontremos en verano e invierno, respectivamente. En algunas regiones las lluvias se concentran en un determinado período del año, lo cual es un fenómeno meteorológico que tampoco tiene incidencia sobre la estación del año.

Cyanobacteria play a crucial role in freshwater and marine ecosystems by providing essential resources to other organisms that rely on oxygen, nitrogen, and organic compounds for their survival. They are capable of producing oxygen through photosynthesis, which is vital for the survival of aerobic organisms in these environments. The oxygen released as a by-product of cyanobacterial photosynthesis contributes to maintaining oxygen-rich conditions in the water.

In addition to oxygen production, cyanobacteria are important nitrogen fixers. They have the ability to convert atmospheric nitrogen gas into useful nitrogen compounds, such as ammonia and nitrates, through a process called nitrogen fixation. These nitrogen compounds are essential nutrients for other organisms, including plants and algae, that require them for growth and metabolism.

Furthermore, cyanobacteria synthesize various organic compounds that can be utilized by other organisms when they decompose. As cyanobacteria break down, they release organic matter into the environment, providing a source of nutrients for other organisms. This decomposition process contributes to the cycling of nutrients in the ecosystem.

Interestingly, cyanobacteria have the ability to use methane as a carbon source and electron donor in cellular respiration. This unique characteristic allows them to coexist with other organisms that rely on oxygen and nitrogen, as they do not directly compete for these resources.

In specific cases, cyanobacteria form symbiotic associations with other organisms. For example, certain species of cyanobacteria live in a mutualistic relationship with water ferns in rice paddies. These cyanobacteria provide nitrogen to the rice plants, acting as natural fertilizers and enhancing their growth.

Overall, cyanobacteria play a vital role in supporting the ecological balance of freshwater and marine ecosystems by producing oxygen, fixing nitrogen, synthesizing organic compounds, and forming beneficial associations with other organisms. Their activities contribute to the availability of essential resources and the overall productivity and sustainability of these environments.
