Answer:

As algas são organismos que anteriormente eram incluídos no Reino Plantae, porém atualmente pertencem ao Reino Protista, sendo a Ficologia (fico = algas; logia = estudo) o ramo da biologia que estuda esses seres: unicelular ou multicelular (filamentosas), eucariontes, fotossintetizantes e viventes em ambientes de água doce (rios, lagos ou superfícies úmidas) ou salgada (mares e oceanos).

Esses organismos autotróficos, dispostos na superfície oceânica (compondo o fitoplâncton), consomem o gás oxigênio dissolvido na água para a sua respiração e liberam através do processo fotossintético cerca de 70 a 90% do oxigênio contido na atmosfera. Recebendo, portanto, a denominação de pulmão do mundo, diferente do que muitos pensam que seja a Floresta Amazônica.

A reprodução assexuada pode ser tanto por divisão binária, isso nas unicelulares, onde a célula se divide ao meio; quanto por fragmentação, mecanismo de cisão de um segmento no talo nas algas multicelulares. Contudo, algumas espécies multicelulares reproduzem por zoosporia, utilizando-se de células flageladas que se desprendem do talo, locomovendo-se até um local favorável para o desenvolvimento.

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.
