Explanation:

Big Brutus is the world's largest electric shovel. It stands 16 stories high amid the fields of rural southeast Kansas. The coal strip mine it helped clear of rock and dirt has long been shut down, and Brutus has been turned into a museum.

The Bucyrus RH400, now owned by Caterpillar, is said to hold the title of the world's biggest hydraulic excavator. This monster is a front shovel excavator and weighs in at around 980 tonnes. This mine chewer has an undercarriage width of 8.6 meters and crawler length of 10.98 meters.

Answer:

All living things are made up of one or more cells.

Explanation:

The cell theory is a universal theory proposed by three scientists viz: Theodor Schwann, Mathias Scleiden, and Rudolf Virchow in the year 1838. These three scientists contributed to the cell theory and proposed the following:

1) All living things are composed of one or more cells

2) Cell is the basic and fundamental unit of life

3) New cells arise from pre-existing cells.

However, at an earlier date specifically 1665, an English scientist named Robert Hooke has discovered and coined the term "cells" in his published book by observing a piece of cork under a microscope. This Hooke's discovery of cells from a once living cork best supports the part of the cell theory that states that: All living things are made up of one or more cells.

FromTheMoon [43]

Answer:

Based on the facts, there is no legal claim he can create against the accounting firm

Explanation:

While it is true that Alonzo had received and accepted a formal proposal by the accounting firm in Los Angeles, it only becomes valid and binding when the contract with the company is signed. Therefore, any event that occurs between the acceptance of the proposal and the signing of the contract does not generate liability in either party. Unfortunately for Alonzo, there's no potential claim agains the accounting firm that he can do.
