Answer» Answer: each of them SLIGHTLY belongs to NEUTRON but if I had to go with only one I will go with 3. Explanation: 1. they are ELECTRICALLY neutral 2. nearly same mass 3. mass is negligible 4.it is present in nucleus reason I SAID three is that electrons are the one with negligible mass not neutron , they had mass slightly more than protons so I think we can't CALL them negligible |

Which among the given statement about ribosome is true-a) Secretes chemical substances like enzymes and hormones.b) Small granular structure which are responsible for protein synthesis. |
|
Answer» Answer: o acids into proteins. Ribosomes are the cellular structures responsible for PROTEIN synthesis. When viewed through an electron microscope, ribosomes APPEAR either as clusters (polyribosomes) or single, tiny dots that float freely in the cytoplasm. They may be attached to the cytoplasmic side of the plasma membrane or the cytoplasmic side of the ENDOPLASMIC reticulum and the outer membrane of the nuclear ENVELOPE. Electron microscopy has shown us that ribosomes, which are large COMPLEXES of protein and RNA, consist of two subunits, aptly called large and small |

B) Describe each category with examples.(i)Autotrophs (ii) Parasitic plants (iii) SaprotrophsAns: |
|
Answer» Answer: 1.) Autotrophs:-Autotrophs are organisms that can produce their own FOOD, using materials from inorganic SOURCES. The word “autotroph” comes from the root words “auto” for “self” and “troph” for “food.” An autotroph is an organism that feeds itself, without the assistance of any other organisms. Example:-Seaweeds are algae. Algae, along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the PRODUCERS in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis 2.) Parasitic plants:-An organism that lives in or on another organism that is its host and profits at the expense of the other by deriving nutrients. or PARASITE is an organism that survives in or on another species, usually at the expense of its host. Examples:Tapeworms, fleas, 3.) saprotrophsSaprotrophs take their food in solution form, from dead and decaying matter. Bacteria, fungi, and fungus-like organisms are examples of saprotrophs. Saprotrophic microbes fungi are also KNOWN as saprobes and saprotrophic plants are called saprophytes. and barnacles Hope it is helpful for you...Mark me as brainliest ☺️thanks |

Iii.Define endothermic reaction. Give an example,iv.How much heat energy is necessary to raise the temperature of 10 kg of water from 40 °C to100 °C?If the speed of light in a medium is 2 x 10% m/s, what is the absolute refractive index of themedium? (Velocity of light in vacuum = 3 x 10 m/s) |
|
Answer» exothermic reaction occurs when the temperature of a system increases due to the evolution of heat. This heat is RELEASED into the SURROUNDINGS, resulting in an overall negative quantity for the heat of reaction ( qrxn<0 ). An endothermic reaction occurs when the temperature of an isolated system decreases while the surroundings of a non-isolated system gains heat. Endothermic reactions result in an overall positive heat of reaction ( qrxn>0 ). Exothermic and endothermic reactions cause energy LEVEL differences and therefore differences in ENTHALPY ( ΔH ), the sum of all potential and kinetic energies. ΔH is determined by the system, not the surrounding environment in a reaction. A system that RELEASES heat to the surroundings, an exothermic reaction, has a negative ΔH by convention, because the enthalpy of the products is lower than the enthalpy of the reactants of the system. C(s)+O2(g)⟶CO2(g)(ΔH = –393.5 kJ) H2(g)+12O2(g)⟶H2O(l)(ΔH = –285.8 kJ) The enthalpies of these reactions are less than zero, and are therefore exothermic reactions. A system of reactants that absorbs heat from the surroundings in an endothermic reaction has a positive ΔH , because the enthalpy of the products is higher than the enthalpy of the reactants of the system. N2(g)+O2(g)⟶2NO(g)(ΔH = +180.5 kJ > 0) C(s)+2S(s)⟶CS2(l)(ΔH = +92.0 kJ > 0) Because the enthalpies of these reactions are greater than zero, they are endothermic reactions. |
