10. The air tubes present ininsects are*o SpiraclesO TracheaeO GillsO Stomata |
|
Answer» Answer: Explanation: The respiratory SYSTEM consists of air-filled tubes or tracheae, which open at the surface of the thorax and abdomen through PAIRED SPIRACLES. The muscular valves of the spiracles, closed most of the time, open only to allow the uptake of oxygen and the ESCAPE of carbon dioxide. |

(49) Write general properties of Acid and Base. Define indicatorand explain how this indicators use for test of acid and basealong with name of indicators. |
|
Answer» Property Acid Base Taste Sour (vinegar) Bitter (BAKING soda) Smell Frequently burns nose USUALLY no smell (except NH3!) Texture STICKY Slippery Reactivity Frequently react with metals to form H2 React with many oils and fats. An acid-base indicator is either a weak acid or weak base that exhibits a color change as the concentration of HYDROGEN (H+) or hydroxide (OH-) ions changes in an aqueous solution. Acid-base indicators are most often used in a titration to IDENTIFY the endpoint of an acid-base reaction. They are also used to gauge pH values and for interesting color-change science demonstrations. |

(3) You are given three solutions A, B and C acid, base and neutral respectively. It isnot possible to identify them just by looking how will you identify the type of solution.(101 |
|
Answer» Three solutions are given: How can we identify the type of solution? There are two possible methods:
Method 1:Litmus Paper:Acidic: ⇒When red litmus paper is added in sample solution A, we can observe no colour change. ⇒When blue litmus paper is added in sample solution A, we can observe that the colour CHANGES to red. ⇒From this, we can say that solution A is acidic.
Basic: ⇒When red litmus paper is added in sample solution B, we can observe that the colour changes to blue. ⇒When blue litmus paper is added in sample solution B, we can observe no colour change. ⇒From this, we can say that solution B is basic.
Nuetral: ⇒When red and blue litmus paper is added in sample solution C, we can observe no colour change. ⇒From this, we can say that solution C is neutral. Phenolphthalein:Acidic: ⇒When Phenolphthalein is added in sample solution A, the solution becomes colourless. From this, we can say that solution A is acidic. Basic: ⇒When Phenolphthalein is added in sample solution B, then the colour of the solution becomes pink. From this, we can say that solution B is basic. Nuetral: ⇒ When Phenolphthalein is added in sample solution C, then the colour of the solution becomes colourless. From this, we can say that solution C is neutral. Like this the type of solution can be identified by using various indicators. By observing change in colour of the solution, we can identify whether the solution is acidic, basic or neutral in nature. Method 2:Universal indicators:⇒From universal indicators, we can check the pH value of a solution. ⇒This method is more efficient because we can identify whether a solution is strongly acidic/basic or weakly acidic/basic in nature. Know some pH values:

Read the paragraph and answer the questions:If heat is exchanged between a hot and cold object, the temperature of thecold object goes on increasing due to gain of energy and the temperature ofthe hot object goes on decreasing due to loss of energy.The change in temperature continues till the temperature of both theobjects have attain the same value. In this process, the cold object gains heatenergy and the hot object loses heat energy. If the system of both the objects isisolated from the environment by keeping it inside a heat resistant box(meaning that the energy exchange takes place between the two objects only),then no energy can flow from inside the box or come into the box.a) How does transfer of heat take place?b) Which principle do we learn about from this process?c) Which property of the substance is measured using this principle ? |

(i) Give the functions performed by each of the followingmicrobes :(e) Aspergillus oryzae |
|
Answer» Please Mark as brainlist Explanation: Characteristics of the Species Aspergillus oryzae plays a pivotal role in Asian food manufacturing, such as saké, shoyu (soy sauce), and miso (soybean paste). For thousands of years, it has been used for making fermented food and beverages. In addition, A. oryzae has been used in the PRODUCTION of industrial enzymes for food processing. A. oryzae is accepted as a microorganism having generally regarded as safe status. A. oryzae is an aerobic filamentous fungus and belongs to the Aspergillus subgenus Circumdati section Flavi, previously known as the A. flavus group. Aspergillus section Flavi CONTAINS industrially important species, such as A. oryzae, as well as agronomically and medically significant fungi, such as A. flavus and A. parasiticus, which produce a potent carcinogenic substance, aflatoxin. Taxonomically, A. oryzae is closely related to A. flavus, A. parasiticus, and A. sojae, which has also been used for shoyu fermentation for a long time. Despite such close relatedness, A. oryzae and A. sojae never produce aflatoxins and are used in fermented food manufacturing. Thus, it is of great importance to differentiate these four species accurately, although recent taxonomical studies on Aspergillus section Flavi have some controversial aspects. A. oryzae is isolated from soils and plants, particularly rice. A. oryzae is named after its occurrence in nature and cultivation industrially on rice, Oryza sativa. A. oryzae has an optimal growth temperature of 32–36 °C (±1 °C) and is unable to grow above 44 °C. It has an optimal growth pH of 5–6 and can germinate at pH 2–8. It has been reported that A. oryzae could grow in corn flour with a water content of about 16%. It generally can grow on media with a water activity (aw) above 0.8, but it rarely grows below 0.8. Like most other fungi, A. oryzae grows vegetatively as haploid multinucleate filaments, designated hyphae, or mycelia. Hyphae of A. oryzae extend at the apical tips and multiply by branching, so that the COLONY covers the surface of the solidified agar medium after several days of incubation. Hyphal growth keeps on going in liquid medium as long as the hyphae are not exposed to air atmosphere. Conidiophore structures, however, which bear asexual reproductive spores called CONIDIA (Figure 1), are produced when hyphae are transferred onto solidified agar medium. When grown on the surface of an agar medium, the colony is initially white because of the vegetative hyphal growth, and then it turns to yellowish green as a large amount of conidia form. In most strains of A. oryzae, the color of fresh culture or conidia is yellowish green, but that of old culture is brown, sometimes green with brown shades. Conidial heads are usually globose to radiate, 100–200 μm in diameter. In A. oryzae, sexual life cycle has not been found as in other industrially important filamentous fungi, such as A. niger and Penicillium chrysogenum. Conidia of A. oryzae are haploid, but multinucleate (conidia have mostly two to four or more nuclei) in contrast to uninucleate conidia of A. nidulans or A. niger. This makes genetic manipulation of A. oryzae more difficult, compared with A. niger. Conidia are large, 5–8 μm in diameter, and spherical to slightly oval. Conidial walls are mostly smooth to finely roughened. Most strains of A. oryzae have only phialides on the vesicles (uniseriate sterigmata), but some contain metulae and phialides (biseriate sterigmata). Stipes of conidiophores are colorless and mostly roughened, to occasionally smooth and less roughened. They are long, in the range 1–5 mm. |
