Explanation:
Dichotomous key refers to the tool or method which helps the scientist to identify organisms.

Answer:
B.) Take samples from the same location each time.
Explanation:
The original answer choices to this question are the following:
- Provide details about the creatures in the "other" category.
- Take samples from the same location each time.
- Collect samples from nearby lakes for comparison.
- Use a more sophisticated net to collect smaller creatures.
Phoebe should take samples from the same location, rather than four different locations. This will overall give her more accurate and reliable results. Some areas of the lake will have more or less wildlife depending on what predators and prey live. She must have a control variable in this survey, otherwise her data will not be correct.
Hope this helps :)

Answer:
The correct answer is option B) "The looseness allows for easy separation of the dead cell layer of epidermis to be shed".
Explanation:
The looseness of the surface are connecting the dermis to the epidermis provides several benefits, however allowing for easy separation of the dead cell layer of epidermis to be shed is not one of them. The dead cell layer of epidermis is located a the stratum corneum, which is the most superficial layer of the skin. The area that connects the dermis to the epidermis is deeper at the skin's anatomy, and is not related with the stratum corneum shedding.
