What is overload? |
| Answer» <p>Overload is an excessive amount of something.</p><p>PLEASE HIT THE LIKE BUTTON</p> | |
| 2302. |
explain overload in detail. |
| Answer» <p>Overloading refers to the ability to use a single identifier to define multiple methods of a class that differ in their input and output parameters. Overloaded methods are generally used when they conceptually execute the same task but with a slightly different set of parameters. </p><p>Overloading is a concept used to avoid redundant code where the same method name is used multiple times but with a different set of parameters. The actual method that gets called during runtime is resolved at compile time, thus avoiding runtime errors. Overloading provides code clarity, eliminates complexity, and enhances runtime performance.</p><p>PLEASE HIT THE LIKE BUTTON</p> | |

How do vaccines works in our body? (AS1) |
| Answer» <p>When foreign invaders such as bacteria orvirusesenter the body, immune cells called lymphocytes respond by producing antibodies, which are protein molecules. These antibodies fight the invader known as an antigen and protect against further infection. According to the Centers for Disease Control and Prevention (CDC), a healthy individual can produce millions of antibodies a day, fighting infection so efficiently that people never even know they were exposed to an antigen.</p><p>Unfortunately, the first time the body faces a particularinvader, it can take several days to ramp up this antibody response. For really nasty antigens like the measles virus or whooping cough bacteria, a few days is too long. The infection can spread and kill the person before the immune system can fight back.</p><p>That's wherevaccinescome in. According to the Children's Hospital of Philadelphia Vaccine Education Center, vaccines are made of dead or weakened antigens. They can't cause an infection, but the immune system still sees them as an enemy and produces antibodies in response. After the threat has passed, many of the antibodies will break down, but immune cells called memory cells remain in the body.</p> | |

7. Answer the following questions.a. Which vaccines are given toinfants? Why? |
| Answer» <p>Diphtheria (the 'D' in DTaP vaccine)Tetanus (the 'T' in DTaP vaccine; also known as Lockjaw)Pertussis (the 'P' in DTaP vaccine, also known as Whooping Cough)Hib (Haemophilus influenzae type b)Hepatitis B.Polio.Pneumococcal Disease.</p> <p>Infants and young children have to face numerous attacks by viruses and bacteria. When you are a bit familiar with Evan infant under age one you will get used to the fact that these children blow big green bubbles from their noses for three or four days every month building up immunity to al kind of common cold viruses. As a child we learn our immune system to cope with these little bastards without much of a do. But some bacteria and viruses are real badasses. The bacteria that cause tetanus cannot be defeated by our immune system. We are dead before the system is ready to cope. When you are vaccinated against tetanus then your immunesystem is ready for the fight and the bacteria do not have a chance. So it happens that our immunesystem is able to cope with most common bacteria and viruses, but some are real killers. Those really dangerous bastards are: small pox, now extinct thanks to a WHO campaign, poliomyelitis, tetanus, diphtheria, whooping cough, measles, mumps, rubella (dangerous for intra uterine babies). New to the system of vaccinations are those against Hepatitis, important for people working in health care, HPV, prevention of cervical cancer and throat cancer. In regions where yellow fever is endemic a vaccination against yellow fever is the right thing to do, the same for rabies, (a terrible killer). Vaccination is the very best the medical science ever had discovered! Follow the advise of your local community health department and when you travel abroad take advise from people who have the knowledge.</p> <p>thanks</p> <p>how is vaccine produced</p> | |

iinDHow do vaccines works in our body?ASWhat are the diff |
| Answer» <p>Vaccinesare like a training course for the immune system. They prepare thebodyto fight disease without exposing it to disease symptoms. When foreign invaders such as bacteria or viruses enter thebody, immune cells called lymphocytes respond by producing antibodies, which are protein molecules.</p><p>Afteryou have beenvaccinated, someof thecells that are responsible for protectingyouagainst disease —yourB lymphocytes — detecttheantigensin the vaccine.TheB lymphocytes will react as ifthereal infectious organism was invadingyour body.</p> | |

| Answer» <p>Oil and Water. The classic example of immiscible liquids is oil and water. The Two liquid which can dissolve in each other and make a homogeneous mixture is called miscible liquid.Like water and milk.</p> <p>Oil and Water. The classic example of immiscible liquids is oil and water. The Two liquid which can dissolve in each other and make a homogeneous mixture is called miscible liquid.Like water and milk.</p> <p>Some examples of miscible solutions include water and organic compounds such as alcohols, aldehydes and ketones. Immiscible solutions include water and many types of oils. A miscible solution is any solution that can be mixed together to form one liquid phase. Immiscible solutions do not mix together and instead form separate layers.</p> | |

| 2317. |
what is diff between acid and base |
| Answer» <p>Any substance with a pH value between 0 up to 7 is considered acidic, whereas a pH value of 7 to 14 is a base. Acids are ionic compounds that break apart in water to form a hydrogen ion (H+). Ionic compounds are a compound with a positive or negative charge. Bases, on the other hand are ionic compounds that break apart to form a negatively charged hydroxide ion (OH-) in water.</p> | |

why fishes have scales on their body |
| Answer» <p>Scales are the exoskeleton located outside a fish body. Scales are hard, transparent and sharp structures which protect fish from predators. Scales also help the fish by getting damaged by corals. These are too slippery as the epidermal cells present under the scales secrete mucous which comes out and forms a covering on the scales. Most of the fish have scales. Only few species do not possess it instead they have a thick covering of mucous on their body as a protection.</p> | |

Why ketone does not exhibit in Electrophillic substitution Rxn? |
| Answer» <p>Because carbonyl groups are strongly polarized: partially positive at the carbon end, partially negative at the oxygen end.</p><p>The result is that the oxygen end is a (rather weak) Bronsted base, while the carbon end is attractive to nucleophiles.</p><p>You should notice that only anionic nucleophiles add to neutral carbonyl groups, because the product of addition is a negative charge on oxygen.</p><p>In order to add a neutral nucleophile, you need to protonate the oxygen first.</p> | |

Why?Under which of the following conditions are you most likelyto fall sick?(a) when you are taking examinations.(b) when you have travelled by bus and train for two days.(c) when your friend is suffering from measles.Why? |
| Answer» <p>option C when your friend is suffering from measles and you come in contact with him/her, there are chances that you can develop infection. because measles is rapidly spreading viral disease which can spread though infected person's saliva or mucus. The infected person may release the infection into the air when they cough or sneeze.therefore you're most likely to fall sick when your friend is suffering from measles. </p> | |
