Answer:
B) Willow Flycatchers can lose eggs to squirrels, weasels, and other predators. The biologist attempts to protect nests by putting metal collars around the base of the windows that keep ground predators from climbing up to reach the nests.
Explanation:
The dynamic of a species depends on its interaction with other species. So in species management plans, among other aspects, it is important to know the trophic webs in which a species is involved and the interactions of that taxonomic group with the others in the chain.
Top-down techniques take decisions from the most global variables to the most inferior or specific ones. When referring to the trophic web, the most global variables are related to top predators, while the most inferior ones are related to the first levels of the chain.
If the researcher needs to adopt a top-down technique, the most suitable one to choose is to protect the Flycatcher´s nests from predators. Predators are the carnivores in the chain that feeds on the Flycatchers´ eggs. This action will interrupt the link between the superior predators and the flycatchers, allowing this last species to recover its population size.

Hello! The interaction between the two system is an inter-dependent relationship. An example of this is that the heart pumps arterial blood to the circulation. The deoxygenated or venous blood returns to the lung where blood is oxygenated. Then the blood flows into the heart chambers and the cycle continues on.
The correct answer is "urine output, 20 ml/hour".
The minimum urine output for a healthy individual is 30 ml/hour, therefore this measurement of urine output is lower than what is considered acceptable. Urine output is an important assessment which can help the monitoring of renal function. Since the patient is recovering from a renal surgery, a significant low urine output should be reported to the healthcare provider.
In a patient recovering from a surgery, a slight increase in temperature is expected. So is the absence of bowel sounds and a small amount of serous sanguineous drainage.
