The substance that neutralizes the effect of poison is called as an “antidote”.
Explanation:
An antidote is a specific remedy or treatment that counteracts the toxic effects of a poison or toxin, often by binding to the harmful substance and rendering it harmless or by promoting its elimination from the body. Antidotes are designed to counteract the specific effects of particular poisons and are used in medical emergencies or cases of poisoning.April 18, 2023 at 11:34 pm in reply to: On the basis of thomson’s model of an atom explain how the atom is neutral as a whole #23973::Thomson’s model of an atom, also known as the “plum pudding” model, proposed that the atom is composed of a positively charged material with negatively charged electrons embedded within it, similar to plums in a pudding.
According to this model, the positive charge of the atom is evenly distributed throughout the atom, while the negatively charged electrons are distributed within this positive material.
This means that the overall charge of the atom is neutral since the positive and negative charges are balanced.
Thomson’s model also explained how atoms can lose or gain electrons to form ions. For example, if an atom loses one or more electrons, it becomes a positively charged ion, while if it gains one or more electrons, it becomes a negatively charged ion. In both cases, the total charge of the ion is no longer neutral since there is an excess of positive or negative charges.
However, the model also had its limitations, as it did not explain some of the observed properties of the atom, such as the spectral lines and stability of the atom.
This led to the development of new models, such as the Rutherford model, which proposed that the positive charge of the atom is concentrated in a small, dense nucleus, and the electrons orbit around it. Nonetheless, the concept of the atom being neutral as a whole still applies in modern atomic theory.
::The depletion in the ozone layer is caused by Chlorofluorocarbons (CFCs).
Explanation:
Chlorofluorocarbons (CFCs) cause ozone depletion by releasing chlorine atoms when they are exposed to ultraviolet (UV) radiation in the stratosphere.The chlorine atoms then react with ozone (O3) molecules and break them apart, forming oxygen (O2) molecules and a chlorine oxide molecule (ClO).
The chlorine oxide molecule can then react with a free oxygen atom (O) to form another molecule of oxygen (O2) and regenerate the chlorine atom, which can then repeat the cycle of ozone destruction. This process is known as the “ozone-depleting cycle.”
One of the reasons that CFCs are particularly effective at causing ozone depletion is that they are very stable and can remain in the atmosphere for many years without breaking down. This means that the chlorine atoms they release can continue to react with ozone for a long time, causing significant damage to the ozone layer.
::Discriminant of 9x2 + 2 = 10x is 28
Solution:
Discriminant of a quadratic equation ax2 + bx + c is
=> b2 – 4ac
Given equation is 9x2 + 2 = 10x
Moving 10x to the left we get
=> 9x2 – 10x + 2 = 0
Comparing with general form of equation
=> a = 9, b = -10, c=2;
Substituting into the discriminant formula, we get
=> (-10)2 – 4(9)(2)
=> 100 – 72
=> 28
So, the discriminant of 9x2 + 2 = 10x is 28

::The full form of atp is Adenosine Triphosphate.
Explanation:
ATP is the source of energy for our body both for usage and storage. ATP is thus called the energy currency of the cell. ATP is produced in Mitochondria in the cell and is the energy source for all the important biological functions.ATP is a chemical made up of pentose ribose sugar, adenine and three phosphate groups. Our body gets energy from ATP by breaking its phosphate bonds.

::Tomato is a natural source of oxalic acid.
Explanation:
Tomato is a natural source of an acid called oxalic acid. Tomatoes have around 50mg of oxalic acid and as it ripes, the content keeps increasing.Oxalic acids act as anti-nutrients in the human body. Anti-nutrients are those substances which block the absorption of nutrients in our body.
Oxalic acids can bind with various minerals like magnesium, iron and mainly calcium. Oxalic acid binds with calcium forming calcium oxalate which can lead to several issues like hypocalcemia, kidney stones etc.
::Salt is obtained from seawater by the process of evaporation.
Explanation:
Evaporation is the process of conversion of a material in liquid state to gaseous state.Here the sea water is evaporated converting it to vapour leaving behind the salts in sea water.
That is how we obtain salt from sea water.
March 8, 2023 at 10:05 pm in reply to: Dissolution of ammonium chloride in water is exothermic or endothermic #23669::The dissolution of ammonium chloride in water is an endothermic reaction.
Explanation:
The dissolution of ammonium chloride in water is an endothermic process. This means that energy is required for the dissolution to occur, and that energy is absorbed from the surroundings. Thus making the system cooler.April 9, 2023 at 2:52 pm in reply to: What would happen to the life of a cell if there was no golgi apparatus? #23959::If there was no Golgi Complex, the following things would get effected in the cell:
Protein Processing
Protein processing and distribution would be impaired, resulting in the accumulation of improperly folded or modified proteins in the cell. This could lead to a variety of cellular dysfunctions or even cell death.Lysosomes
Lysosomes, which are responsible for breaking down cellular waste and debris, would not be formed without the Golgi apparatus. As a result, the cell would be unable to dispose of damaged or dead molecules and organelles, which could eventually lead to cell death.Packaging and Transporting Materials
The Golgi apparatus is responsible for packaging and transporting materials within the cell. Without it, the cell’s ability to transport materials to the appropriate locations within the cell, as well as its ability to secrete substances outside the cell, would be severely compromised.Acrosome Production
The production of acrosomes, which are necessary for the fertilization of an egg cell, would be impaired without the Golgi apparatus. This could lead to infertility in organisms that rely on acrosome production for successful reproduction.::There are 25 prime numbers between 1 to 100.
The prime numbers between 1 to 100 are as follows:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.What is a prime number?
A prime number is a positive integer greater than 1 that has no positive divisors other than 1 and itself.How to find if a number is prime or not?
Simply, if the number is n, we can divide the given number with a range from 2 to n-1 and if any number in the range perfectly divides n, then it is not a prime otherwise it is a prime.::The discriminant of 9x2 + 2 = 10x is 28
General form of a quadratic equation => ax2 + bx + c = 0
Formula for discriminant => b2 – 4ac
Comparing general form, we get
a = 9, b = -10, c = 2
Discriminant => (-10)2 – 4(9)(2)
=> 100 – 72
=> 28
The discriminant of 9x2 + 2 = 10x is 28
