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.
Answer:
herbicide ZWD10
Explanation:
Independent variable in an experiment are defined as the variable that can be changed or controlled as per the requirement of the experiment to determine its effect on the dependent variable.
In the given experiment, herbicide ZWD10 is an independent variable as it's quantity in experiment can be changed or controlled and we are looking for its effect on corn growth which is a dependent variable.
Hence, the correct answer is herbicide ZWD10.
Answer:
200.000 in je m
Explanation:
1 je m is equal to 1000 mm.
Therefore 0.2 mmm will be equal to 1000 × 0.2 mmm
This will give us 200 je m.
Answer:
C. Coupled reactions establish an electrochemical gradient across a membrane.
Explanation:
- During cellular respiration in mitochondria, and during photosynthesis in chloroplasts, the electron transport chain requires a proton gradient to pump protons across the membrane by active transport.
- Protons flow back across the membrane by facilitated diffusion through ATP synthase, which utilizes them to phosphorylate ADP to ATP.
- This process of ATP synthesis by harnessing the elctrochemicaal gradient geenrated by the diffusion of protons across the biological membrane through ATP synthase is called chemiosmosis.
