Answer:

Formation of oxygen and abiotic molecules.

Explanation:

The present day organisms use oxygen for process of respiration. There are very few organisms which require source other than oxygen. The first organisms which make oxygen from photosynthesis were cyanobacteria.

The formation of abiotic molecules like nucleotides and amino acids were responsible for origin of life. These molecules arranged together, thus forming large molecules like nucleic acid and proteins.

Biological and environmental influences that are similar for individuals in a particular age group, regardless of where they are
Flauer [41]

Answer:

age-graded

Explanation:

Age-graded influences are biological and environmental events that influence the dynamic interaction between an individual and their environment at certain ages of the individual’s course of life. They are events that are expected to occur in a particular setting based on chronological age. For example, depending on the cultural settings of an individual, an individual is expected to graduate high school at a certain age, or get married at a certain age. Another example is puberty and menopause which are biological influences that are age-graded.

What is the significance of understanding changes to the information stored in DNA?
Otrada [13]

Answer:

DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.

The instructions stored within DNA are read and processed by a cell in two steps: transcription and translation. Each of these steps is a separate biochemical process involving multiple molecules. During transcription, a portion of the cell's DNA serves as a template for creation of an RNA molecule. (RNA, or ribonucleic acid, is chemically similar to DNA, except for three main differences described later on in this concept page.) In some cases, the newly created RNA molecule is itself a finished product, and it serves an important function within the cell. In other cases, the RNA molecule carries messages from the DNA to other parts of the cell for processing. Most often, this information is used to manufacture proteins. The specific type of RNA that carries the information stored in DNA to other areas of the cell is called messenger RNA, or mRNA
