Can’t help you there love i need points tho
Answer: The correct option is B (self-replicating molecules, such as RNA and DNA)
Explanation:
The current theory of the process of evolution makes use of present day knowledge of genes and chromosomes to explain the source of genetic variation upon which natural selection works. These genes are discrete units of inheritance which determine hereditary characteristics. All the information for the inheritable characteristics of an individual are contained in these genes.
When a cell divides, the genes duplicate themselves so that each daughter cell has an identical set of genes as the original parent cell. These genes are passed from parents to offspring in the gametes of the parents.
Gene are found in the DNA( Deoxyribonucleic acid) molecules or RNA (Ribonucleic acid) molecules. These molecules are capable of self replication due to a process called mutation. Mutations are random changes in DNA that alter genetic information and sin introduce new characteristics. They may occur
--> in body cells or
--> during gamete formation.
Thus, evolution from vesicles to true cells is through self replicating molecules through the process of mutation which is the raw material for evolution
An organism that is composed of many cells, gets its nutrition from decaying organisms, and has cell walls belongs to kingdom fungi.
<h3>What is taxonomy?</h3>
Taxonomy is the system of classifying all living things into appropriate groups. The incorrect statement about taxonomy is; "any different orders of organisms belong to the same species."
The kingdom that contains organisms that can survive by photosynthesis or by consuming organic material in dark conditions is fungi.
The difference between mammals and reptile is that the presence of hair in mammals that is not found in reptiles.
An organism that is composed of many cells, gets its nutrition from decaying organisms, and has cell walls belongs to kingdom fungi.
The reason why plants and blue-green algae are classified in different groups is because Blue-green algae use their chlorophyll differently from plants.

Answer:
radiometric dating methods
Explanation:
The oldest rock layer will be at the very bottom, and as time goes on, more layers will form making the top layer the youngest layer and the bottom layer the oldest. This method can determine the amount of radioactive decay of certain elements which can help them make a geologic time scale.
