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.
Response: Option D.
Justification:
Active transport refers to how molecules or solutes travel through a membrane based on solute concentration differences.
This process is constant due to diffusion, which ensures ongoing movement of solutes across the membrane. Cells have reduced sodium (Na+) levels but increased potassium (K+) levels. Therefore, sodium's electrical and concentration gradients promote the ion's entry into the cell, assisted by the positive charge of Na+, which encourages inward movement to the negatively charged interior.
Thus, the right choice is D.
Answer: starch
Explanation:
Starch, a carbohydrate, is produced by plants and is primarily found in seeds and tubers.
Starch is also used to treat cotton shirts, as it forms glycosidic bonds which contribute to the fabric's quality.
This compound consists of amylose and 70%–90% amylopectin. Amylose, a polysaccharide, comprises D-glucose monomers linked by the α-1,4-glycosidic bond, forming a helical structure with six glucose units per full turn.
Amylopectin, another polysaccharide, features glucose molecules primarily linked through α-1,4-glycosidic bonds, with occasional branching due to α-1,6-glycosidic connections. Each amylopectin molecule can have many thousands of glucose segments, with branches occurring roughly every 25 to 30 units.
Answer:
Option C is the correct selection.
Explanation:
- Rupal concludes that aluminum might be the most potent oxidizer by only completing a quarter of her research. Due to the incomplete nature of her study, she ended up with inadequate information and thus arrived at flawed findings.
- The oxidizing agent that is more active in the excitation prequel list is potassium, not aluminum (even though aluminum is known to be a highly effective metal and oxidant).
Other available choices do not pertain to the scenario described. Therefore, Option C is deemed the suitable answer.
The most suitable answer would be Finches, as they feed on easily accessible plants.
I hope this information is useful.
