## What is the 2nd part of the cell theory?

The second part states that cells are the basic units of life. These parts were based on a conclusion made by Schwann and Matthias Schleiden in 1838, after comparing their observations of plant and animal cells.

## What is the smallest unit of cell?

The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellularâ€”consisting only of a single cellâ€”while others, for instance, mammalians, are multicellular.

## Is the cell The smallest unit of matter?

Living things are highly organized and structured, following a hierarchy that can be examined on a scale from small to large. The atom is the smallest and most fundamental unit of matter. All living things are made of cells; the cell itself is the smallest fundamental unit of structure and function in living organisms.

## What are the basic units of elements?

An atom is the basic unit of a chemical element. Atoms are made out of three main parts: protons, neutrons and electrons. Protons and neutrons are contained inside the very center of the atom, which is called the nucleus.

## What is a unit rate in construction?

A unit-rate is a very basic and detailed item that can be found in a lot of estimates or project descriptions. They are used for bidding and detailed estimating purposes.

## How do you calculate concrete per unit?

For calculating the rate per unit of an item following sub-heads are estimated and added together to get the rate per unit of an item.

1. Quantity of material and Its cost.
2. Labour cost.
3. Cost of equipment or Tools and plants( 1.5%)
4. Water charges (1.5%)
5. Overhead expenses (2 to 5%)
6. Contractor profit (10%)

## How do you calculate the cost of one unit?

For a typical manufacturing environment, however, the unit cost formula is: Unit Cost = Variable Costs + Fixed Costs / Total Units Produced.
