The Experimental Design was open reading frame (ORF) is the part of a reading frame that contains no stop codons. Its transcription pause site is located after the ORF, beyond the translation stop codon if it happened that it will cease before it stop, an incomplete protein will form during the translation.

Iron rich deposits that formed about 2 billion years ago have red layers. Layers formed before then were not red. The red layers
Amanda [17]

Answer:

D. The biosphere change the lithosphere

Explanation:

The red formed due to oxygen which is produced by plants in the process of photosynthesis. This oxygen then reacted with iron atom and formed oxidized iron layers of sedimentary rock. So here plants are responsible for the formation of these layers and we considered plants as part of biosphere so we can say that biosphere is responsible for the change of lithosphere.

Otrada [13]

Answer:

The steps that can be seen in this story are observation and the questioning phase, which can also be called elaboration of the problem.

Explanation:

The scientific method is a set of phases that are able to guide researchers to the creation of scientific knowledge, through an experiment. This method is essential for conducting scientific research, allowing an experiment to be managed in a way that promotes answers to scientists' questions. The scientific method presents the phases called observation, questioning (or elaboration of the problem), elaboration of hypotheses, experimentation, analysis of the results and conclusion.

In the story shown in the question above, we can see the phases called observation and questioning. The observation takes place the moment Fleming noticed a fungus capable of growing on colonies of bacteria that cause throat infections, killing them. This observation made him enter the questioning phase, when he wondered if the fungus was able to prevent the growth of these bacteria.

Population: a particular group or type of people or animals living in a place.

Gene pool: the stock of different genes in an interbreeding population.

Mutations: the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.

Lateral Gene Transfer: the movement of genetic material between unicellular and/or multicellular organisms other than by the transmission of DNA from parent to offspring (reproduction).

Single-gene Traits: when a trait is linked to one gene-pair that consists of two alleles.

Polygenic Traits: is one whose phenotype is influenced by more than one gene.
