When both the P and A site are occupied and a third tRNA anticodon comes to the ribosome, what happens to the first anticodon?
Answers
Answer:
The first anticodon leaves the ribosome through the E-site
Explanation:
Translation is the second stage of gene expression. It occurs in the ribosomes (organnelles of protein synthesis) where amino acid sequence is synthesized using a mRNA template. The tRNA (transfer RNA) is responsible for reading the mRNA codon using its ANTICODON, which is complementary to the mRNA codon.
The tRNA reads the mRNA codon and carries the amino acid that corresponds what it reads. tRNA has three binding sites on the ribosome; A-site, P-site and E-site. A tRNA molecule with the complementary anticodon binds to the codon on the P-site, and carries its corresponding amino acid. Another tRNA with complementary anticodon occupies the A-site, carrying the corresponding amino acid again.
Once both sites are occupied, the tRNA on the P-site transfers its amino acid to the one on the A-site to form a peptide bond. This causes the ribosome to shift the tRNA on the P-site, allowing the one on the A-site to be free. When this happens, the anticodon of the first tRNA on the P-site leaves the ribosome via the E-site in order to bind to another complementary mRNA codon and continue the translation process.

A class is learning about the evaporation step in the water cycle using a simple model. The model consists of a 1-L container of water. When the container is open, and it receives sunlight, the water can freely evaporate from the container. The students design an experiment using the model. In the experiment, the container will be filled and left open outside from dawn until dusk at different times of the year. The students will run the experiment only on days with clear weather. As a basis of their experiment, the students make an assumption that more water will evaporate from their model when more solar energy is present. Which of the following is a result that the students could predict in order to test their assumption?

Answers
Is Solid waste point source pollution or non point source pollution?
Answers
Answer:
Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area. As an example, picture a city street during a thunderstorm. As rainwater flows over asphalt, it washes away drops of oil that leaked from car engines, particles of tire rubber, dog waste, and trash. The runoff goes into a storm sewer and ends up in a nearby river. Runoff is a major cause of nonpoint-source pollution. It is a big problem in cities because of all the hard surfaces, including streets and roofs. The amount of pollutants washed from a single city block might be small, but when you add up the miles and miles of pavement in a big city you get a big problem.
In rural areas, runoff can wash sediment from the roads in a logged-over forest tract. It can also carry acid from abandoned mines and flush pesticides and fertilizer from farm fields. All of this pollution is likely to wind up in streams, rivers, and lakes.
Airborne pollutants are major contributors to acid rain. It forms in the atmosphere when sulfur dioxide and nitrogen oxides combine with water. Because acid rain results from the long-range movement of those pollutants from many factories and power plants, it is considered nonpoint-source pollution.

What classifying organisms in science?The study of relationships among living things is known as taxonomy, and the formal classification of species into groups based on those supposed relationships is known as taxonomy. The similarities and differences between organisms are used to classify them.
Scientists classify things using a branching method. The domain is the largest category. Kingdoms are the next level of division within each domain, followed by phyla, classes, orders, families, genus, and species. It helps us comprehend how more sophisticated organisms develop from less complicated ones.
Therefore, They are classified in a chronological system, starting with the first organisms discovered by people and through to the most recently discovered organisms.

Answer: The Low Pressure systems will usually be found more North where it gets verycold but can really happen anywhere, and High pressure systems are usually found in the Southwest during winter.
Explanation:
High Pressure:A high pressure system has higher pressure at its center than the areas around it. Winds blow away from high pressure. Swirling in the opposite direction from a low pressure system, the winds of a high pressure system rotate clockwise north of the equator and counterclockwise south of the equator. This is called anticyclonic flow. Air from higher in the atmosphere sinks down to fill the space left as air is blown outward. On a weather map, you may notice a blue H, denoting the location of a high pressure system.
Low Pressure:
A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation. Because of Earth’s spin and the Coriolis effect, winds of a low pressure system swirl counterclockwise north of the equator and clockwise south of the equator. This is called cyclonic flow. On weather maps, a low pressure system is labeled with red L.

Mechanical energy can take on many forms, but these different forms can be categorized as either potential energy or energy of motion. The height an object is dropped from has an effect on the amount of energy in the object. Let’s conduct an experiment to see the effect.
:How does the height of an object affect the amount of mechanical energy it contains?
1:Variables What is the test variable?
Answers
The height of an object is crucial to the amount of energy something has because the higher up it is the most potential energy it has and kinetic energy it could have.
For example, if the height of a basketball was just a couple inches off the ground, it would not have a large amount of potential energy because because there is not much of a fall between the ball and the ground. However, if the ball was higher, there would be more potential energy because there is more room to fall.
---
"What is the test variable?"
The test variable, or independent variable in this case would be the height, as the scientist is changing the height in order to get different results in the total mechanical energy, which would be the dependent variable.

Write a scientific explanation that describes total world carbon emissions in 2050 if the world’s population decreases to five billion people.
Claim:
Evidence:
Reasoning:
Answers
Answer:
The earth would eventually become become a brown and grey wasteland and the blue sky and rainbows and things like that will be rare rain would be highly acidic
Evidence: There are less people which means less cars will be driven less oil will be used etc. also fossil fuels are non renewable resource which means fossil fuels will be harder to find overall diving up prices of gas,heating,etc which might make Deter people from using fossil fuels and switching to something cheaper. At this point to people will dislike fossil fuels more then now.
Reasoning: I think people won’t like fossil fuels for 2 good reasons. First the driven up price. Second there will be noticeable effects from fossil fuels it 2050. It can make crops harder to grow which could lead to famine and a Recession because driven up food prices and it will hurt the economy. Towns will slowly flood. Arctic species will die so on. So a poor family’s that can’t afford food won’t spend more money on something that overall hurts them. They will despise people who use fossil fuels and it will become socially wrong. Civilization at that time might also be working on them self. Population decreased a major amount. Something bad happened. And if what ever caused the decline in population was caused by humans which there’s no way to tell, they might try to improve human habits try not to begin wars, work on helping each other, and most importantly don’t harm there plant.

Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
