What is cell division ?Explain |
|
Answer» Cell division is the process by which a parent cell divides into two or more daughter cells.[1] Cell division usually occurs as part of a larger cell cycle. In eukaryotes, there are two DISTINCT types of cell division: a vegetative division, WHEREBY each daughter cell is genetically identical to the parent cell (mitosis), and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes (meiosis).[2] Meiosis results in four haploid daughter cells by undergoing one round of DNA replication followed by two divisions. Homologous chromosomes are SEPARATED in the first division, and sister chromatids are separated in the second division. Both of these cell division cycles are USED in the process of sexual reproduction at some point in their life cycle. Both are believed to be present in the last eukaryotic common ancestor.hope it helps thank you |

3. Show the reduction taking place during photosynthesis, Explain with the help of a balanced chemical equation. |
| Answer» EXPLANATION:Photosynthesis can be represented using a chemical EQUATION. The overall balanced equation is... 6CO2 + 6H2O ------> C6H12O6 + 6O2 Sunlight energy Where: CO2 = carbon dioxide H2O = water Light energy is required C6H12O6 = GLUCOSE O2 = oxygenIt seems COUNTERINTUITIVE that carbon dioxide, the compound that's reduced in photosynthesis, gains electrons. This electron transfer is CALLED reduction because the addition of negatively charged electrons reduces the overall charge of the molecule; that is, it makes the molecule less positive and more negative. the formulaThe oxidation-reduction action of photosynthesis transforms batches of six water molecules, H2O, and six carbon dioxide molecules, CO2, into one glucose molecule, C6H1206, and six molecules of O2, which is breathable oxygen. | |

Why cages are not advised installed near sea grass beds and coral reefs |
| Answer» AQUACULTURE is of growing importance in the global seafood production. The environmental impact of aquaculture will largely depend on the type of environment in which the aquaculture system is placed. SOMETIMES, due to the abiotic or biotic conditions of the seascape, certain aquaculture systems tend to be placed within or near specific ecosystems, a phenomenon that in this thesis is referred to as aquaculture system - ecosystem LINKS. The exposed ecosystems can be more or less SENSITIVE to the system specific impacts. Some links are known to be widespread and especially hazardous for the subjected ecosystem such as the one between the shrimp aquaculture and the mangrove FOREST ecosystem. The aim of this thesis was to identify and investigate causes and consequences of other spatial links between aquaculture and ecosystems in the tropical seascape. Explanation: | |
