Las algas azul-verdosas impactan el agua dulce y están directamente relacionadas con el escurrimiento agrícola y urbano.
Las fuertes lluvias de la primavera pasada probablemente causaron que el Lago Okeechobee liberara agua con algas azul-verdosas hacia ríos y canales. La espesa capa verde se deslizó sobre embarcaderos, represas y ríos, fluyendo a través de afluentes hacia el océano.
Las algas azul-verdosas (cianobacterias) son un tipo de microorganismos procariontes y autótrofos que cuentan con pigmentos fotosintéticos (clorofila y ficocianina), por lo que su ADN muestra que son bacterias.
Bacterias es la respuesta correcta.
The AraC protein associated with the ara operator functions as a repressor to prevent transcription of the ara operon. In the presence of arabinose, the AraC protein acts as an activator; however, in its absence, it serves as a repressor. When arabinose is not available, AraC remains as a
homodimer. One AraC molecule attaches to the ara initiator while another binds to a distinct regulatory region in the DNA known as the ara operator.
The nurse must take steps to limit the amount the child absorbs into their system. Additionally, the nurse should promote the elimination of any toxins ingested by the child while providing necessary supportive care.
Answer:
The correct statements are:
Structures that are analogous do not suggest a common ancestor. They serve the same purpose but have different anatomical structures. An illustration of an analogous structure is the wing of a bat compared to that of a butterfly.
Explanation:
Analogous structures refer to those that perform a similar function across different organisms but have distinct anatomical features. They do not indicate a shared ancestor.
For instance, the wings of bats and butterflies are both utilized for flight, yet their anatomical constructions differ significantly from one another.
Every scientific exploration commences with a concept that leads to an unanswered question. To arrive at an answer, this question evolves into a research question, which subsequently becomes the basis for formulating a hypothesis. A suitable experiment will be designed to address the research question and provide answers. The outcomes of the experiment will be examined, leading to a conclusion.
The findings from this experiment will then be shared in a peer-reviewed journal to inform fellow scientists of the new insights gained.<span />
