  1. Example for oldest high level language is

  1.  C++ 

  2.  Java 

  3. Fortran 

  4. None


Fortran is considered to be the oldest high-level programming language. Fortran (short for "Formula Translation") was developed by IBM in the 1950s for scientific and engineering computations. It was designed to be a high-level language that could be easily read and written by human programmers, while also providing efficient machine code for the computer to execute.


Therefore, the answer to your question is "Fortran." While C++ and Java are also high-level programming languages, they were developed much later than Fortran, with C++ being developed in the 1980s and Java in the 1990s.

The first mechanical calculating machine is attributed to Blaise Pascal, a French mathematician and philosopher who invented the machine in the mid-17th century. The device, called the Pascaline, was a geared mechanical calculator that could perform addition and subtraction with up to eight digits.


Therefore, the answer to your question is "Blaise Pascal." While other inventors, such as Wilhelm Schickard and Gottfried Leibniz, also contributed to the development of mechanical calculators, Pascal is generally credited with inventing the first functional machine. Charles Babbage, on the other hand, is often considered the "father of the computer" for his work on the Analytical Engine, a mechanical computer designed in the 19th century.

source - wikipedia



Cytochrome oxidase is a type of metalloprotein, which is a protein that contains one or more metal ions as part of its structure. Specifically, cytochrome oxidase is a membrane-bound enzyme that contains heme, copper, and zinc ions.


Cytochrome oxidase is a critical component of the electron transport chain, which is the process by which cells generate energy in the form of ATP. The enzyme catalyzes the final step of the electron transport chain, the transfer of electrons to oxygen to form water.


Therefore, the answer to your question is "Metalloprotein." Coenzymes are organic molecules that assist enzymes in catalyzing chemical reactions, simple proteins are proteins that only contain amino acids, and flavoproteins are a type of protein that contain flavin as a cofactor.


  1. Maltose is hydrolysed by

  1.  Amylase 

  2.  peptidase 

  3.  Maltase 

  4.  Sucrose

source - adobe stock



Maltose is a disaccharide composed of two glucose units linked by an α(1→4) glycosidic bond. It is commonly found in grains such as barley, rice, and wheat.


Maltose is hydrolyzed by the enzyme maltase, which is produced by the small intestine and breaks down maltose into two glucose molecules. This process is important for the digestion and absorption of carbohydrates in the small intestine.


Therefore, the answer to your question is "Maltase." Amylase is an enzyme that breaks down starch into smaller glucose molecules, peptidase breaks down proteins into amino acids, and sucrose is a disaccharide composed of glucose and fructose, which is hydrolyzed by the enzyme sucrase.


  1. Sphingomyelins found in large quantities

  1.  Brain and nerve tissues 

  2. Brain and heart tissues

  3. Brain and body tissues 

  4. Brain and liver tissues


Sphingomyelins are a type of sphingolipid, which are complex lipids found in cell membranes. They are particularly abundant in the nervous system and are essential for the structure and function of nerve cells.


Therefore, the answer to your question is "Brain and nerve tissues." Sphingomyelins are found in large quantities in the brain and nerve tissues because they play a critical role in maintaining the integrity and function of these tissues. They are also present in smaller amounts in other tissues, including the heart, liver, and lungs.


  1. ‘Goitrogens’ related with 

  1.  Thyroxin 

  2.  Trypsin 

  3. Tyrosine 

  4. Thiamine


Goitrogens are substances that interfere with the function of the thyroid gland by inhibiting the uptake of iodine, which is necessary for the production of thyroid hormones. Thyroid hormones, such as thyroxine (T4), play a critical role in regulating metabolism, growth, and development.


Therefore, the answer to your question is "Thyroxin." Goitrogens are related to thyroxin because they can interfere with the production of thyroid hormones and lead to goiter, a condition characterized by the enlargement of the thyroid gland.


It's worth noting that some foods contain natural goitrogens, such as cruciferous vegetables like broccoli, cauliflower, and cabbage. However, the risk of developing goiter due to consuming these foods is generally low, especially in individuals with adequate iodine intake.


  1. K-value is rejected at the % of 

  1.  20-25 % 

  2.  10-15% 

  3.  25-30% 

  4.  50-60%


  1. Reduction rate of E.coli during freezing and frozen spoilage 

  1.  95% 

  2. 85% 

  3. 98% 

  4. 93%

source - live science



The reduction rate of E.coli during freezing and frozen spoilage can vary depending on several factors such as the initial bacterial load, the freezing rate, storage temperature, and duration. However, generally, freezing can significantly reduce the number of viable E.coli bacteria.


According to studies, freezing can reduce E.coli counts by an average of 90-95%, which is equivalent to a 90-95% reduction rate. Therefore, the closest answer to your question would be "95% reduction rate" as it falls within the range of the typical reduction rate of E.coli during freezing.


It's worth noting that while freezing can reduce the number of viable bacteria, it does not completely eliminate them. Also, once frozen food thaws, the remaining bacteria can continue to grow and spoil the food if it's not properly handled and stored.


  1. LSF is 

  1. Liquid seaweed fertilizer 

  2. Liquid solvent fertilizer

  3.  Liquid super freezer 

  4. None


LSF typically stands for "Liquid Seaweed Fertilizer." This is a type of fertilizer made from seaweed that is dissolved in water to create a liquid fertilizer that can be easily applied to plants. Seaweed fertilizer is a natural and organic source of nutrients and trace elements that can help improve plant growth and health.


Liquid Seaweed Fertilizer (LSF) is a type of organic fertilizer made from seaweed that has been processed and dissolved in water. Seaweed, also known as marine macroalgae, is a type of plant that grows in the ocean and is rich in essential nutrients and trace elements that are beneficial for plant growth. LSF is produced by harvesting seaweed from the ocean, washing and drying it, and then grinding it into a powder. The powder is then mixed with water to create a liquid fertilizer that can be easily applied to plants.


LSF is an excellent source of natural plant growth hormones such as auxins, cytokinins, and gibberellins, which help to promote cell division, root growth, and overall plant development. It also contains essential nutrients such as nitrogen, phosphorus, and potassium, as well as trace elements such as iron, zinc, and magnesium, which are important for plant growth and health. These nutrients are readily available to plants in a form that they can easily absorb and utilize.


One of the key benefits of using LSF is that it is a natural and organic fertilizer that is free from synthetic chemicals and pesticides. This makes it an ideal choice for gardeners who are looking for an eco-friendly and sustainable way to fertilize their plants. Additionally, LSF can help to improve soil quality by promoting the growth of beneficial microorganisms and improving soil structure, which can lead to better water retention and nutrient availability.

  Classification of caudal fin  The caudal fin, or tail fin, in fish can be classified into different types based on its shape and structure. The caudal fin, or tail fin, is a critical anatomical feature in fish, serving various functions essential for survival. Here are the primary functions of the caudal fin: Propulsion : The caudal fin is the main propulsive force for most fish, allowing them to swim forward. By moving the fin side to side, fish generate thrust that propels them through the water. Different types of caudal fins provide varying degrees of speed and power. Maneuverability : The shape and flexibility of the caudal fin allow fish to make precise movements, including quick turns and sudden stops. This maneuverability is crucial for avoiding predators, catching prey, and navigating complex environments like coral reefs or dense vegetation. Stability: The caudal fin helps maintain balance and stability in the water, preventing the fish from pitching (tilting forwa...

Ganga Action Plan I (GAP I)     Ganga Action Plan I (GAP I) was the first major initiative taken by the Government of India to clean and restore the Ganga River, one of the most important and sacred rivers in the country. Launched in 1985, this plan was a response to the alarming levels of pollution affecting the Ganga due to untreated sewage, industrial effluents, and other waste discharges from various sources along its course. Key Aspects of Ganga Action Plan I: Objective: The primary objective of GAP I was to improve the water quality of the Ganga River to acceptable standards by preventing pollution from entering the river. Initially, the goal was to reduce pollution levels, but in a 1987 meeting led by Prof. M. G. K. Menon, the objective was revised to restoring the river's water quality to the "Bathing Class" standard. The Bathing Class standard includes the following criteria: Bio-Chemical Oxygen Demand (BOD): ...
