Explanation:
Transcription is the first process that occurs in protein synthesis. It involves the use of the stored information in the DNA molecule to synthesize a mRNA molecule.
Transcription, which occurs in the nucleus of eukaryotes and cytoplasm of prokaryotes, is catalyzed by an enzyme called RNA polymerase. RNA polymerase binds to the double-stranded DNA and begins to unwind it (Initiation). This unwinding causes the nucleotide bases to be exposed in order for the RNA polymerase enzyme to read.
The enzyme reads the bases of the DNA and begins to synthesize RNA nucleotides using the complementary base pairing rule (Elongation) i.e. Adenine base paired with Uracil base (RNA), and Guanine paired with Cytosine etc.
The single-stranded mRNA is released at the end of the transcription process (termination). This is basically what occurs in transcription.
The gene coding for the protein untwists and unzips.
RNA nucleotides form complimentary base pairs with the DNA bases.
Hydrogen bonds and sugar-phosphate bonds form and the mRNA strand is synthesized.
mRNA peels off the DNA and moves to the cytoplasm.

Kai has a see-through glass tank with air, plants, and animals that eat those plants. He sealed the tank so no material can get into or out of it, but light can get in when the tank is not covered.
The light for the tank has been on all day, and Kai measured the carbon in the air and found that it is decreasing. How is carbon moving between the air and the living things in the tank? What is happening to the amount of carbon in living things? Explain your thinking as completely as possible.
Answer:
1. Carbon is moving from the living things in the tank into the air when they respirate, and from the air back into plants via photosynthesis
2. The amount of carbon in living things is increasing as plants use the carbon in the atmosphere, and animals eat the plants.
Explanation:
According to the question, a well sealed tank contains air, plants and animals. Since light can get into the tank, plants can perform photosynthesis. Living things in the tank release carbon in form of carbondioxide (CO2) gas through respiration. Plants then make use of this carbondioxide (CO2) to synthesize carbon-containing food (glucose) in the presence of sunlight. This process is called PHOTOSYNTHESIS.
Animals eat those plants and the stored carbon in the plants gets transferred to them. The animals release this carbon into the air again in the form of carbondioxide when they respire. Hence, carbon in the tank moves from the living things (respiration) into the air and back into plants (photosynthesis).
2. Since the amount of carbon in the air is decreasing, the carbon is being used by the living things in the tank. Plants absorb the carbon in the atmosphere for photosynthesis, then animals eat the plants to get the carbon. Therefore, the amount of carbon in the living things is increasing.
1. Carbon is flowing from the living organisms in the tank into the air by the process of respiration and from the surrounding back into plants via photosynthesis.
The animals in the tank utilize the oxygen when they inhale while during exhalation carbon dioxide is liberated. The carbon dioxide in the tank is used by the aquatic plants to produce food and energy in this way the level of oxygen and carbon dioxide is maintained in the tank.2. The quantity of carbon in living, are expanding as plants use this carbon in the process of photosynthesis from the environment and animals consumes those plants.
The deposited carbon in the food gets spent by the animals and they release this carbon back via exhalation. Therefore the quantity of carbon in living things is increasing.To learn more about respiration and photosynthesis follow the link:

1) Sucessão ecológica é o nome dado a uma série de mudanças que ocorrem nas comunidades de um determinado ecossistema. Sobre a sucessão primária, marque a alternativa correta: A sucessão primária ocorre em uma área que já foi ocupada por uma comunidade anteriormente. A sucessão primária pode acontecer em áreas desmatadas, por exemplo. A sucessão primária ocorre em ambientes estéreis, onde nunca houve a ocupação por seres vivos. A sucessão primária é o último estágio da sucessão ecológica.
Answer:
A sucessão primária ocorre em ambientes estéreis, onde não havia vestígios de organismos vivos que a ocupassem antes. Esse ambiente pode ser um local vulcânico em que a lava derretida destruiu o meio ambiente ou foi causada por dunas. A comunidade inicial de organismos para habitar esses ambientes é conhecida como sucessores primários ou colonizadores primáriosrimários
Explanation:
Primary colonisers initiate primary succession as such they are important to the future of such environments. They are though breeds of organisms that make use of scarce resources to survive in harsh environments. Without their ability to survive, there will be little or no way other forms of succession can take place. Reasons, why they may not persist, maybe too much stress imposed on them by the environment and above all their inability to compete when other successors come on board.
