Speciation, the evolutionary process by which new species are formed, is clearly responsible for the ultimate generation of species diversity over geologic time.
Answer:
The correct answer is - cytoplasm of the cell.
Explanation:
Cellular respiration is the bunch of metabolic reactions that convert biochemical energy from the glucose or other nutrients into ATP ( adenosine triphosphate) and releases water and carbon dioxide as waste products.
This process has three stages and the very first stage is glycolysis which is taking place in the cytoplasm of the cell. In this stage, the glucose molecule converts into the two molecules of pyruvate and produce energy.
Thus, the correct answer is - cytoplasm of the cell.
Answer:
The transfer of mature pollen grain from anther of the flower to the stigma of the same flower of the same [species is called self pollination.
Generally, the transfer of pollen grains by wind,animals,and water to stigmas is called pollination. It is a means of vegetative propagation which ensures reproduction.
Therefore during self pollination, the same genes are distributed from one generation to another. Thus genetic purity is ensured. It also ensured reproductive success. because there is little chance of the pollen grain getting lost in transit. It is also certain a particular plant would always breed true.
Additionally it prevent the process of transfer of genes in some transgenic crops( rice, maize) where through genetic engineering some genes are introduced in their genome.
The only negative effect is lack of genetic diversity. Therefore after a period of time the plants get weak and prone to diseases and infection. Because of poor resistant from lack of variation.
Explanation:
Answer:
Protein Synthesis
Explanation:
DNA transcribes information into the RNA of the nucleus. Transcription is making copies of information from DNA and applying that information into a new format. The RNA first stays in the nucleus and then travels to the ribosome on the rough endoplasmic reticulum through the cytoplasm. Here the translation of RNA done. The information the DNA which was copied onto the RNA during transcription is translated into a sequence of amino acids in this stage. In the next step, the amino acid chains, or polypeptides, are constructed in the correct sequence to form proteins.
After synthesis of protein, a part of the rough endoplasmic reticulum takes off and separates to form a protein-filled vesicle. Then this vesicle travel to the Golgi complex where the protein is modified if needed and then repackaged into a new vesicle. The vesicles then carry out the protein to another organelle where it will be used within the cell or to the plasma membrane for secretion purposes.
When you cross a plant with a dominant Trait with a recessive version of the same trait, the recessive trait disappears in the F1 Generation and re-appears in the F2 Generation.
