Answer:
Decomposers
Explanation:
The diagram in this question illustrates a food web, which is a series of interlinked food chains in an ecosystem. In a food chain as depicted in the image, the arrows point to the organism that feeds on another organism. For example, an arrow is pointing from Idaho fescue to an Elk meaning that the elk will feed on that plant.
Different trophic levels constituting organisms exists in the food web including; producers (plants), primary consumers, secondary consumers, tertiary consumers etc. However, as observed in the image, a general arrow carrying along all the organism is pointing towards the organism in the question mark. This organism is called DECOMPOSER.
A decomposer, usually a microorganism, is an organism that breaks down dead organisms and returns the nutrient to the soil for recycling. All organisms in the food web will eventually die and when they do, they'll be decomposed by a decomposer. This is why the arrow pointing towards the decomposers include all organisms.
The US Environmental Protection Energy or EPA is responsible for ensuring the country's drinking water to be safe and with good quality. It is in the Safe Drinking Water Act of 1974 that reclaims in ensuring the purity of drinking water Americans drink. Under the said Act, every citizen has his/her own roles and responsibilities. However, the implementation of such is governed by the EPA.
Answer:
This phenomenon is known by neuroscientists as Neuroplasticity, or brain plasticity
Explanation:
Think of plasticity, Neuroplasticity, or brain plasticity, is the simplest terms, as the ability of parts of the brain to adapt their function or ability to change throughout life.
Structural plasticity - brains ability to change in response to the environment.
Functional plasticity-brains ability to change in response to the activities.
Answer:
A. They were part of the control group
Explanation:
In a scientific experiment, the CONTROL GROUP as opposed to the experimental group is the group that does not receive the experimental treatment. This acts as a standard for comparison.
In this question, the EXPERIMENTAL VACCINE is the experimental treatment or independent variable that was added. The five animal test subjects that was injected with this vaccine are called the EXPERIMENTAL GROUP while the other five test subjects that were rather injected with a PLACEBO are called CONTROL GROUPS.
