Add your answer
Q2. What is Founder effect?
Ans. 
Founder effect is the reduced genetic diversity that results when a population is descended from a small number of colonizing ancestors.
• Occurs when a small group of individuals establishes a new population

• Genetic diversity is limited to the alleles present in the founders

• Can lead to increased frequency of certain genetic disorders

• Common in isolated populations like island communities

Q3. What is incomplete dominance?
Ans. 
Incomplete dominance is a genetic concept where neither allele is completely dominant over the other, resulting in a blending of traits.
• In incomplete dominance, the heterozygous genotype produces a phenotype that is a blend of the two homozygous phenotypes.

• For example, in snapdragons, red flowers (RR) crossed with white flowers (WW) result in pink flowers (RW).

• Incomplete dominance is different from co-dominance where b...read more

Q2. Difference between consolidation and compaction of soils?
Ans. 
Consolidation is the gradual settlement of soil due to expulsion of water, while compaction is the process of increasing soil density by reducing air voids.
• Consolidation is a time-dependent process, while compaction is typically achieved in a short period of time.

• Consolidation occurs due to the expulsion of water from soil voids under load, while compaction involves applying external force to reduce air voids.

• Consolida...read more

Q4. Define determinate and non determinate structures
Ans. 
Determinate structures have fixed dimensions and can be analyzed using equations, while non-determinate structures have redundant members and require additional analysis methods.
• Determinate structures have a fixed number of unknown forces that can be solved using equilibrium equations.

• Non-determinate structures have more unknown forces than equilibrium equations, requiring additional analysis methods like virtual work ...read more

Q1. What is distillation
Ans. 
Distillation is a separation process that utilizes differences in boiling points to separate components in a liquid mixture.
• Used in the production of alcoholic beverages, e.g., whiskey and vodka.

• Commonly applied in petroleum refining to separate crude oil into gasoline, diesel, and other products.

• Involves heating a liquid to create vapor and then cooling the vapor to form a liquid.

• Can be performed in batch or continuou...read more

Q2. What is third law of thermodynamics
Ans. 
The third law of thermodynamics states that as temperature approaches absolute zero, the entropy of a perfect crystal approaches zero.
• Entropy is a measure of disorder; at absolute zero, a perfect crystal has no disorder.

• The third law helps in understanding the behavior of materials at very low temperatures.

• It implies that it's impossible to reach absolute zero in a finite number of steps.

• Example: Helium becomes a super...read more

Q3. What is batch reactor
Ans. 
A batch reactor is a closed system where reactants are added, allowed to react, and products are removed in discrete batches.
• Used in chemical processes like pharmaceuticals, food production, and polymers.

• Examples include fermentation tanks for brewing beer and reactors for producing biodiesel.

• Batch reactors allow for precise control over reaction conditions.

• They are ideal for small-scale production or when product dema...read more

Q2. What are the types of rocks and their examples?
Ans. 
Rocks are classified into three main types: igneous, sedimentary, and metamorphic, each with unique formation processes.
• Igneous rocks form from cooled magma or lava. Example: Granite.

• Sedimentary rocks are formed from the accumulation of sediments. Example: Sandstone.

• Metamorphic rocks arise from the transformation of existing rocks under heat and pressure. Example: Schist.

Q3. What is the difference between P wave and S wave?
Ans. 
P waves are primary waves that travel through solids and liquids, while S waves are secondary waves that only move through solids.
• P waves (Primary waves) are compressional waves that move faster than S waves.

• S waves (Secondary waves) are shear waves that can only travel through solid materials.

• Example: P waves can travel through the Earth's liquid outer core, while S waves cannot.

• P waves are the first to be detected by...read more

Q4. What is Ocean Acidification ?
Ans. 
Ocean acidification is the process by which the ocean becomes more acidic due to increased CO2 absorption.
• Caused by increased atmospheric CO2 from human activities like burning fossil fuels.

• Leads to lower pH levels in ocean water, affecting marine life.

• Coral reefs are particularly vulnerable; acidification hampers their ability to calcify.

• Shellfish, such as oysters and clams, struggle to form shells in more acidic wate...read more

Q5. What is Typhoon?
Ans. 
A typhoon is a powerful tropical cyclone that forms in the Northwest Pacific Ocean, characterized by strong winds and heavy rain.
• Typhoons are classified as tropical cyclones with sustained winds exceeding 74 mph.

• They typically form over warm ocean waters and can cause severe weather events.

• Examples include Typhoon Haiyan (2013) and Typhoon Mangkhut (2018), both causing significant damage.
