People take ivermectin primarily because it is an effective, approved medication for treating certain parasitic infections in humans. It has been used safely for decades to treat conditions such as river blindness (onchocerciasis), strongyloidiasis (a type of intestinal worm), and scabies. More recently, some people have taken ivermectin for unapproved or unsupported reasons, most notably during the COVID-19 pandemic, when it was promoted online as a preventive or cure despite a lack of reliable evidence supporting that use. ...

We adjust coefficients-the numbers placed in front of chemical formulas-when balancing chemical equations because coefficients change the quantity of molecules, not the identity of the substances. We do not adjust subscripts because subscripts define the chemical structure and identity of a compound. Changing a subscript would mean creating a different substance, which violates the reality of the reaction. In short: Coefficients = how many molecules participate Subscripts = what the molecule actually is Balancing equations is about conserving atoms, not redefining molecules. ...

We celebrate Lohri to mark the end of winter and the arrival of longer days, especially in northern India. At its core, Lohri is a harvest and seasonal festival. It expresses gratitude for nature’s cycles, celebrates agricultural abundance, and honors community, warmth, and renewal. The festival is closely associated with Punjab, Haryana, Himachal Pradesh, and parts of North India, and is traditionally linked to the rabi crop season, particularly wheat. The bonfire at the center of Lohri symbolizes the sun’s return, warmth, and life after cold months. ...

People eat khichdi on Makar Sankranti because it is traditionally believed to provide warmth, balance, and nourishment during the seasonal shift that occurs around this festival. The dish-made from rice and lentils, often with ghee and mild spices-aligns closely with Ayurvedic dietary principles for winter-to-spring transition. Over time, this practical food choice became a ritualized cultural practice, especially in parts of North and Central India. In short: khichdi is eaten not for symbolism alone, but because it suits the body’s needs during this time of year, and that practicality evolved into tradition. ...

We have belly buttons because they are the scar left behind after the umbilical cord is cut at birth. Before birth, the umbilical cord connects a developing fetus to the placenta. Through this cord, oxygen, nutrients, and waste products are exchanged between the mother and the fetus. After birth, the cord is no longer needed and is clamped and cut. When the remaining stump dries and falls off, it leaves a small scar on the abdomen - what we commonly call the belly button, or navel. ...

We need political parties because modern democracies cannot function without organized groups that represent ideas, interests, and people. Political parties help citizens choose their leaders, form governments, make laws, and hold power accountable. Without political parties, democracy would become chaotic, inefficient, and largely unworkable-especially in large countries like India. At the Class 10 level, the core idea is simple: political parties make democracy practical. They connect ordinary people to the government by organizing opinions, contesting elections, and running the administration once elected. ...

We sneeze when we’re sick because the body is trying to clear irritants, viruses, mucus, and inflammatory chemicals from the nasal passages. Illness-especially colds, flu, COVID-19, and sinus infections-irritates the lining of the nose. That irritation overstimulates nerve endings, which triggers a sneeze reflex designed to expel the problem forcefully. In simple terms: sneezing is a defensive reflex, not a symptom by itself. When you’re sick, the nose becomes inflamed, congested, and chemically active, making that reflex easier to trigger and harder to suppress. ...

People wear black on Makar Sankranti mainly for practical, seasonal reasons, not religious ones. Black absorbs and retains heat, which helps keep the body warm during mid-January-one of the coldest periods in many parts of India. Over time, this practical habit became a widely followed cultural custom, especially in regions like Maharashtra. There is no religious mandate in Hindu scriptures that requires wearing black on Makar Sankranti. The practice is rooted in climate, comfort, and local tradition rather than theology. ...

Makar Sankranti is celebrated to mark the sun’s transition into the zodiac sign Makara (Capricorn), an astronomical event that signals the end of winter and the beginning of longer, warmer days in the Northern Hemisphere. Unlike many Hindu festivals that follow lunar calendars, Makar Sankranti is based on the solar calendar, which is why it falls on nearly the same date every year, usually January 14 or 15. At its core, the festival represents renewal, hope, and gratitude-especially gratitude for the harvest and for the sun, which is seen as the source of life, energy, and prosperity. ...

Co-codamol usually starts to relieve pain within 30 to 60 minutes after you take it. For most people, noticeable pain relief occurs around the one-hour mark, with peak effect typically reached within 1 to 2 hours. The duration of pain relief is generally 4 to 6 hours, which is why it is commonly prescribed or recommended at intervals within that range. This timing applies to standard oral tablets taken with water. Liquid forms may act slightly faster, while taking it after a heavy meal may delay the onset. ...

Iron tablets usually start improving symptoms within 1-2 weeks, but meaningful recovery takes longer. Most people with iron deficiency begin to feel less fatigued and less short of breath after 2-3 weeks. However, restoring iron stores in the body typically takes 2-3 months, and in some cases up to 6 months, depending on how low iron levels were and whether the underlying cause has been addressed. In short: you may feel better relatively soon, but treatment needs to continue well beyond that to fully correct the deficiency. ...

For most people, Laxido starts to work within 1 to 2 days of taking it. Some notice softer stools or easier bowel movements within 24 hours, while for others it can take up to 3 days to have a clear effect. This slower onset is normal and expected. If Laxido is being used for severe constipation or faecal impaction, the timeline is longer. In those cases, it may take several days of regular dosing before bowel movements resume, because the medication is first working to soften and rehydrate hardened stool. ...

For most people, vitamin D does not work immediately. If you are deficient, measurable improvements typically begin after 4-8 weeks of consistent supplementation, with full effects often taking 2-3 months. In cases of severe deficiency, it can take 3-6 months to fully restore healthy blood levels. Some people notice subtle improvements-such as better energy, mood, or fewer aches-within a few weeks. Others feel nothing until blood levels rise enough to affect bones, muscles, or immune function. Vitamin D works gradually because it changes how your body regulates calcium, hormones, and immune signaling over time, not instantly. ...

A VPN (Virtual Private Network) is a tool that creates a secure, encrypted connection between your device and the internet. Instead of connecting directly to websites and online services, your traffic is routed through a VPN server, which masks your real IP address and protects your data from being easily seen or intercepted. In practical terms, a VPN helps with three core things: privacy, security, and location masking. It does not make you invisible online, but it significantly reduces how easily your internet activity can be tracked, monitored, or tampered with-especially on public or untrusted networks. ...

An incident response drill is a planned practice exercise where an organization simulates a crisis-such as a cybersecurity breach, system outage, data leak, or safety incident-to test how well its people, processes, and tools respond. The goal is not to “pass” the drill. The goal is to reveal weaknesses before a real incident does: unclear roles, slow decision-making, broken communication paths, missing access, or flawed assumptions. In simple terms, it is a fire drill for operational or digital emergencies. ...
