According to google
So the ribosome moves along way and many tRNA molecule transport the correct amino acid to make the correct sequence which is to be formed and only stops when mRNA shows 'STOP' codon. So there is a chain of polypeptide which is synthesised by copying the DNA and this is how proteins are made.
and for clarification t-RNA is transfer RNA and m-RNA is messenger RNA
Mario sets up an experiment to determine the source of the oxygen gas produced by photosynthesis. To determine this, he uses an isotope of oxygen called O-18. He labels the O-18 oxygen so he can follow its path through photosynthesis. Plant A is given carbon dioxide that contains the O-18 isotope. Plant B is given water that contains the O-18 isotope. When he examines the oxygen from both plants, only plant B produced O-18 oxygen. This indicates that the source of oxygen is water. The photosynthesis involves the transfer of electrons between the photosystem I and II. The water gets split into oxygen, hydrogen ions and electrons in the photosystem I. The electrons move to the photosystem II where the carbon fixation into sugars takes place. The plant A will have O-18 isotope in its synthesised sugar molecule, which gets stored inside it.
Answer:
For example, a haploid human nucleus (i.e. sperm or egg) normally has 23 chromosomes (n=23), and a diploid human nucleus has 23 pairs of chromosomes (2n=46). A karyotype is the complete set of chromosomes of an individual.
Explanation:
Answer:
Some practices from the recommended list of physical/cultural control that you could do year-round to help control pests are as follow:
1. We can use those plant species that are more competitive. These plant species include release of chemical toxins that suppress other plants and insects.
2. Use of large Hight quality seeds.
3. By using narrow spacing in row and increasing seeding rate.
4. By using shallow seeding technique which allow desired plant species to grow and develop faster above the surface of soil.
5. By ensuring that our plant species is perfectly placed in that growing environment which is optimized with every specs.
6. By rotating the crops
7. By rotating plant species with different growing cycles and seasonal cycles.
8. By rotating herbicides with alternative modes of action to delay the herbicide resistance development.
