proteins from animal origin are called first class proteins. meat and fish are first class proteins because they contain all the essential amino acids (which cannot be made by the body), plant proteins are called second class proteins.
what is the difference between first and second class proteins
The main difference between a first class and a second class lever is the relative placement of the effort, load, and fulcrum. In a first class lever, the fulcrum is positioned between the effort and the load. In a second class lever, the load is between the fulcrum and the effort. Examples of first class levers include a seesaw, while examples of second class levers include a wheelbarrow.
The location of the effort, load, and fulcrum determine if a lever is a first, second, or third-class lever. In a first-class lever, the fulcrum is between the effort and the load. In a second-class lever, the load is between the fulcrum and the effort. In a third-class lever, the effort is between the fulcrum and the load.
What is the difference between buying a 1st class and a 2nd class ticket on the train in England?

On the Titanic, the first class people were extremely wealthy. The second class people were people who worked hard and earned money, such as teachers.
The distinguishing characteristic of first-class levers is that the fulcrum lies between the effort force and the resistance force. Second-class levers have the resistance force between the fulcrum and the effort force. Third-class levers have the effort force between the fulcrum and the resistance force.
Actually, the First Class lever is the only one that has.
A First Class lever is one in which the fulcrum is locatedbetween the effort and the load.A Second Class lever is one in which the load is locatedbetween the fulcrum and the effort.A Third Class lever is one in which the effort is locatedbetween the fulcrum and the load.
SNCF first class tickets offer more spacious seating, complimentary food and drinks, and access to lounges. Second class tickets provide standard seating and amenities without the additional perks of first class.
A cantilever is an example of a first-class lever, where the fulcrum is located between the effort and the load. This means that the force is applied on one side of the fulcrum and the load is on the other side.
A wheelbarrow is a second-class lever. In a second-class lever, the load is between the effort (force) and the fulcrum, which allows for a mechanical advantage in lifting and moving heavy loads with less effort.
