3 why is that ? i Glass can be made from Sand but sand cannot be made from gas glass??? |
|
Answer» Now you see it, now you don't. Glass is a bit of a riddle. It's hard enough to protect us, but it shatters with INCREDIBLE ease. It's made from opaque sand, YET it's completely TRANSPARENT. And, perhaps most surprisingly of all, it behaves LIKE a solid material... but it's also a SORT of weird liquid in disguise! You can find glass wherever you look: most rooms in your home will have a glass window and, if not that, perhaps a glass mirror... or a glass lightbulb. Glass is one of the world's oldest and most versatile human-created materials. Let's find out some more about it.I hope it's help youplease make me brainlests |

Describe an activity that gives an understanding of'electroplating' |
|
Answer» tion:Electroplating is the process of depositing a layer of a metal on a metallic or a nonmetallic electrode by electrolysis in an electrolytic cell.Let us take an iron spoon which is to be electroplated with copper. For this, we take a copper plate and an iron spoon as electrodes and copper sulphate (CuSO 4) is taken as an electrolyte. The electrodes are connected through an external circuit as shown in FIGURE. On passing CURRENT through the electrolyte, it is decomposed into Cu 2+and (SO 4) 2−ions.As Cu 2+ion is positively charged, it moves towards the negative terminal i.e. iron spoon and GETS deposited on it. Thus, iron spoon gets PLATED with copper. There is no scarcity of Cu atoms because the copper atoms go into the SOLUTION from the positive terminal i.e. copper plate. This process called electroplating continues until the iron spoon gets coated with copper. |

Answer» Explanation:Magnesium sulfate or magnesium sulphate (in British English) is a chemical compound, a salt with the formula MGSO 4, consisting of magnesium cations Mg2+ (20.19% by MASS) and sulfate anions SO2− 4. It is a white crystalline solid, soluble in water but not in ethanol. Magnesium sulfate is usually ENCOUNTERED in the form of a hydrate MgSO 4·nH 2O, for various values of n between 1 and 11. The most common is the heptahydrate MgSO 4·7H 2O, known as Epsom salt, which is a household chemical with many traditional uses, including bath salts.[1] The main use of magnesium sulfate is in agriculture, to correct soils deficient in magnesium (an essential plant nutrient because of the role of magnesium in chlorophyll and photosynthesis). The monohydrate is favored for this use; by the mid 1970s, its PRODUCTION was 2.3 million tons per year.[2] The anhydrous form and severl hydrates occur in nature as minerals, and the salt is a significant component of the water from some springs. |

Q1. Compare and contrast the mode of nutrition in mycoorhiza and mycoheterotrophs. |
|
Answer» tion:The mycorrhizal SYMBIOSIS is arguably the most important symbiosis on earth. FOSSIL records indicate that arbuscular mycorrhizal interactions evolved 400 to 450 million years ago [1] and that they played a critical role in the COLONIZATION of land by plants. Approximately 80 % of all known land plant species FORM mycorrhizal interactions with ubiquitous soil fungi[2]. The majority of these mycorrhizal interactions is mutually beneficial for both partners and is CHARACTERIZED by a bidirectional exchange of resources across the mycorrhizal interface. The mycorrhizal fungus provides the host plant with nutrients, such as phosphate and nitrogen, and increases the abiotic (drought, salinity, heavy metals) and biotic (root pathogens) stress resistance of the host. In return for their beneficial effect on nutrient uptake, the host plant transfers between 4 and 20% of its photosynthetically fixed carbon to the mycorrhizal fungus [3]. In contrast to mutually beneficial mycorrhizal interactions, some mycoheterotrophic plants (approximately 400 plant species from different plant families, such bryophytes, pteridophytes, and angiosperms) rely on mycorrhizal fungi for their carbon supply. These plants have lost their photosynthetic capabilities and parasitize mycorrhizal fungi that are associated with neighbor autotrophic plants. |
