Why is small intestine of herbivores longer than carnivorous

Posted by Sumit Sabar 5 years, 3 months ago

CBSE > Class 10 > Science

1 answers

Gaurav Seth 5 years, 3 months ago

The small intestine is longer in herbivore than in carnivore because herbivores eat only grass which is full of cellulose and the digestion of cellulose takes a long time. Bile is a digestive juice secreted by the liver and stored in the gall bladder. The function of bile is to assist fat digestion and absorption in the gut. The length of small intestine differs in various animals depending on the food that they eat. Herbivores need a longer small intestine to allow cellulose to be digested as taken from green plants.

Gaurav Seth 5 years, 3 months ago

Lencho was a hardworking farmer. He laboured like an ox. He had good knowledge of farming and knew his crop needed a downpour to give him good yield.

Lencho had great faith in God. He knew how to read and write. He wrote a letter to God for help when his crops were totally ruined by hailstones.

He was a simple and innocent farmer. He could not reason out things. He blamed the post-office employees for cheating him of 30 pesos and called them ‘A bunch of crooks’.

But Lencho was a caring head of the family. He got sad and worried that his family would have to go hungry.

Yogita Ingle 5 years, 3 months ago

Griffin was a lawless person but by profession he was a scientist. His landlord disliked him and tired to get rid of him.In revenge griffin set fire to the house and ran away. He had no money and so he stole and robbed people after becoming invisible. When je went into London store, he gave himself the pleasure of clothing. He fed himself without regards to any expenses. Such a behaviour is never expected from a scientist. He also robbed the shopkeeper at Drury Lane and robbed in of whatever he could find. When he exhausted all his money he had stolen,then again he robbed a clergyman. He even attacked the inn keeper and his wife. Later when the police came to arrest him,he threw off his clothes and became invisible and ran away. One who doesn't obey law and fails to behave properly, he is surely a lawless person.

Define oxidising and reducing agents with proper examples

Posted by Sofia Sharma 5 years, 3 months ago

CBSE > Class 10 > Science

2 answers

Yogita Ingle 5 years, 3 months ago

An oxidizing agent (oxidant), gains electrons and is reduced in a chemical reaction. It is also known as electron acceptor. The oxidizing agent is usually in one of its higher possible oxidation states as it will gain electrons and be reduced.

Examples of oxidizing agents are:

potassium nitrate
halogens
nitric acid

A reducing agent (reductant), loses electrons and is oxidized in a chemical reaction. It is typically in one of its lower possible oxidation states and is known as an electron donor. A reducing agent is oxidized because it loses electrons in the redox reaction.

Examples of reducing agents are:

formic acid
the earth metals
sulfite compounds

Tushar Learning And Entertainment Site 5 years, 3 months ago

An oxidizing agent is substance which oxidizes something else. In the above example, the iron(III) oxide is the oxidizing agent. A reducing agent reduces something else. In the equation, the carbon monoxide is the reducing agent. Oxidizing agents give oxygen to another substance. Reducing agents remove oxygen from another substance.
