Answer: Carbon cycle is very important for the plants and animals that are divided into 4 steps and these steps are:
1.The carbon enters the atmosphere in the form of carbon dioxide.Example: respiration and combustion.
2.The carbon dioxide present in the environment is used by the plants and plants expel oxygen after the process of photosynthesis.
3. Animals present in the environment eat the plants and pass on the carbon in the food chain. They exhale carbon dioxide into the environment.The plants and the animals die after a certain period of time.
4. The body of plants and animals is consumed by decomposes and the carbon is returned into the atmosphere in the form of carbon dioxide else fossils of plants and animals are formed which contains carbon.
Answer:
False. There are 20 amino acids, but 64 possible codons.
Explanation:
Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. The total number of possible codons is 64, from which 61 codify amino acids -more than one codon codify for the same amino acid-. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.
The codons indicating the initiation or stop points during the translation process are:
• The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule. However, other codons might be used as well. Prokaryote cells might use the codons GUG or UUG.
• The end codons are UAA, UAG, UGA.
The spindle gradually lenghtens during prophase.Towards the end of the prophase stage,the nuclear envelopes break down,and each of the microtubules reach from each cell pole to the cell's equator an
