It would be C, by their composition and texture.
The answer is DNA. DNA is vital for all living beings and
this is made up of molecules called nucleotides. Each nucleotide contains a
phosphate group, a sugar group and a nitrogen base. The four types of nitrogen
bases are adenine. There are three main functions of DNA to our body, this
facilitate occurring mutations and even in a single nucleotide. Then it forms
RNA and proteins and this exchange the genetic material of parental chromosomes
during meiotic cell.
Answer: The correct answer is-
C.They replaced carbon dioxide with oxygen in the atmosphere.
Cyanobacteria ( also known as blue green algae) is a large phylum of bacteria that is capable of synthesizing its own food using carbon dioxide and water in the presence of sunlight ( photosynthesis).
They contain a green pigment called chlorophyll that absorbs energy from sunlight and helps in the formation of food ( glucose). They release oxygen as a byproduct in the atmosphere.
As these organisms utilize carbon dioxide ( that is present in the atmosphere) to give oxygen in return, therefore, they affected early atmosphere of Earth by replacing carbon dioxide with oxygen.
Thus, option C) is the right answer.
Answer:
this doesnt make sense please look over your question and correct the wording
Answer:
<em>The correct option is D) Ethyl alcohol is produced.</em>
Explanation:
Fermentation can be described as a process by which energy is extracted by organisms such as bacteria and yeast.
Sugars are converted into alcohol by this metabolic process occurring in certain microorganisms. There are two main types of fermentation:
Fermentation which takes place in the presence of oxygen is termed as aerobic fermentation.
The process of fermentation which occurs in the absence of oxygen is termed as anaerobic respiration.
Hence, as alcohol will be produced from both types of fermentation, optic C is correct.
