1. Independent Variable – This is the element changed or controlled in an experiment. Here, it is the labs, since they are given to one class but not the other.
2. Dependent Variable – This represents what is measured in the experiment and depends on the independent variable. In this case, it is the average test scores.
3. Hypothesis – A testable prediction. Here, it suggests that the class participating in labs will perform better than the one without labs.
4. Control Group – The group that does not receive the experiment variable; in this example, the class without labs.
5. Experimental Group – The group exposed to the variable being tested, here the class that completes labs.
6. Constants – The same quantity and type of notes and homework provided to both classes.
7. Possible threats to accuracy – Potential issues include improper application of independent or dependent variables, or misuse of statistical analysis, among others.
Answer:
The Trypanosoma most closely resembles green algae.
Explanation:
Trypanosoma exhibits structural similarities to green algae, which is unicellular. The primary similarity between Trypanosoma and green algae lies in their flagella, both utilizing them for movement from one location to another. Both are unicellular organisms where a single cell manages all life processes.
The appropriate choice is d. In C3 plants, conserving water encourages photorespiration.
Euglena presenta un color verde gracias al clorofila que se encuentra en los cloroplastos de este organismo, y la estructura corporal situada en su base se llama flagelo.
Explanation:
Las Euglenas son especies que habitan en aguas dulces y saladas, y se encuentran en gran cantidad en cuerpos de agua interiores, donde pueden proliferar y teñir la superficie del agua de zanjas y estanques de un color verde.
Este color verde que producen se debe en gran parte a la clorofila que se halla en sus cloroplastos, la cual es el pigmento responsable del color verde. Este pigmento también es el causante de la coloración en este caso.
Las Euglenas cuentan con una estructura corporal especializada, ubicada en la base de su cola, que les permite moverse.
Esta estructura especializada se denomina flagelo.
