Answer: The timeline in which life first evolved on Earth was the Archaen eon.

Life originated on earth in the early Archean eon, approximately 3.5 billion years ago.

The geological time scale depicts the sequence of events which took place on Earth. Eon occupies the largest unit in the geological timescale. There are four eons reported in the geological time. Archaen eon is the second eon on earth, dated 3.9 bya to 2.5 bya. It is also called as Archaeozoic Eon.

The most primitive form of life is prokaryote which appeared in the early Archean eon.

Biocentrism is not considered when looking at life-centered environmental ethics
Murljashka [212]

The given statement is not true.  

Biocentrism in an ecological and political sense, as well as, in an ethical perspective encompasses intrinsic value to all the living creatures. It is an understanding of how the earth functions, mainly as it associates with biodiversity.  

The term biocentrism covers all the environmental ethics, which outspread the status of the moral object from human beings to all the living creatures in nature. Biocentrism witnesses each species as a component of the living biosphere.  

It witnesses the outcomes of minimizing biodiversity on both the large and small scales and emphasis towards the innate values all the species exhibits towards the environment.

lozanna [386]

Most bacteria live in a solution that is hypotonic relative to the cytoplasm of the bacteria. This means that the bacterial cell is constantly taking in water. The cell wall of a bacterium is a peptidoglycan polymer that is tightly cross-linked. This would therefore function to:_________-.

A. regulate the flow of most molecules into and out of the bacterial cell.

B. provide a rigid wall that prevents the cell from swelling.

C. provide a rigid wall that prevents the cell from shrinking.

D. confirm a close relationship to plant cells that have a similar structure and live in hypotonic solutions.

E. make all bacteria fairly uniform in metabolic chemistry.

Answer:

B. provide a rigid wall that prevents the cell from swelling.

Explanation:

When organisms are present in hypotonic surroundings, their cells that are in contact with the surroundings tend to gain water. Bacteria present in hypotonic solution would gain water as their cells are hypertonic than the surroundings. The entry of water would increase the volume of cytoplasm and could lead to the bursting of the cell. However, the presence of a cell wall made up of cross-linked peptidoglycan prevents the swelling of the bacterial cell and allow them to survive in hypotonic surroundings.
