The answer is <span>d. homologous structures.
Homologous structures are </span><span>similar structures shared by different species. For example, the anatomy of joints in bones of birds and dinosaurs, support the idea that these two groups have a common ancestor. But since these two groups are different enough to be separated into different classes, it can be concluded that they evolved from the common ancestor.</span>
Pangea began to separate.
The teacher most likely asked for additional trials because it was necessary to see data from more plants before the conclusion could be accepted.
Explanation:
- Any experiment should have multiple trials given so that accuracy of the result could be obtained.
- Repeating same experiments tests the consistency of a particular result and makes sure that the results will not be effected by random events occurring within the system or surrounding.
- Thus the conclusion becomes more precise and accurate.
glucose is stored in carbon bonds
Answer:
C. primary cell wall → plasma membrane → cytoplasm → vacuole.
Explanation:
Every molecule or particle which enters into a cell, it must pass through several cellular structure at different level means it also depends on the type of molecule like size, shape, and nature (characteristics). On the surface of root cell, potassium ion pass through the primary cell wall which is most outer layer of plant cell, then it passes the second layer called plasma membrane, in the plasma membrane cytoplasm is present and when potassium ion reaches the cytoplasm then it will enter into the vacuole present in cytoplasm.
