It changes because it goes through phases of growth and changes size and it developed more.
Hope this helps.
Transcription occurs in the nucleus of the cell. RNA polymerase breaks the hydrogen bonds and unzips a portion of DNA. RNA nucleotides match the DNA strand forming mRNA. In mRNA thymine is replaced by uracil. Once mRNA is formed it leaves the nucleus through a nuclear pore into the cytoplasm. The purpose of mRNA is to remove the protein code out of the nucleus without pulling the DNA out. mRNA then needs to find ribosomes in the cytoplasm which can be found on the rough ER. mRNA has read three bases at the same time and these are called codons. Ribosomes read the mRNA code and add the correct amino acid using tRNA. tRNA has an anti-codon on one end which will match a specific codon, and a specific amino acid on the other end. This will make translation happen.
Translation- mRNA attaches to a ribosome and a start codon must be read. tRNA brings the first amino acid which matches the codon on mRNA. The next tRNA molecule moves in and matches with the codon on mRNA while amino acids form a peptide bond. First tRNA detaches itself and mRNA shifts for the next tRNA molecule to come in. Protein grows until a stop codon is reached and then it's ready to finish folding to become functional.
Answer:
ATP and NADPH
There are two end products of the light reaction of photosynthesis, ATP and NADPH. These molecules are produced during the cyclic and the non-cyclic photophosphorylation reactions. These are the products which are used in the dark reactions.
Explanation:
Some of the equipment the student can use are:
Nets
Underwater cameras
pH indicators
among others.
<h3>What does the student want to study?</h3>
The student wants to find out if there are invertebrates and fish or if the conditions of the pond would support these types of organisms.
<h3>What does the student need to do?</h3>
In this situation, there are two main approaches:
- Study invertebrates and fish: This approach implies finding out if there are already invertebrates and fish in the pond, to do this, the student can
- Directly observe organisms by using a special camera.
- Use a net to catch organisms in the pond and then classify the organisms.
- Study the conditions: This approach implies determining if the pond has the conditions for invertebrates and fish to live. To do this, the student will need to measure conditions such as:
- Nutrients in the pond.
- Temperature.
- Ph.
This will require equipment such as pH indicators.
