The correct answer among the choices given is the last option. In Florida, the standard defined speed limit in a residential area is 30 mph. In the United States, the speed limit in urban areas is 30 mph and in unpaved roads is 35 mph. In interstate roads the limit is at 70 mph.
The criteria of the indicator species that does not meet is:
<u>Found at the base of any food chain.</u>
<u>Option: B</u>
<u>Explanation:</u>
As an early warning system for environmental problems, indicator species are chosen for their sensitivity to environmental conditions. If the selected indicator species decrease in numbers or any health factor, it symbolizes to see for detrimental effects such as soil impurity, pollution in water/air, habitat fragmentation or drastic variation in climates.
Apart from being sensitive to change, these species must also be representative of the other organisms in the ecosystem, easily observable and must be sampled, and they should react continuously to environmental changes. So from the above conditions, it is clear that species found in any base of food chain is not the criteria.

Plants competing for sunlight or growing in dark conditions will develop elongated stems and poorly developed leaves. They are often tall and thin, lacking color in their stems. In severe cases, this physiological condition is called etiolation. Therefore, the darker the environment, the taller the plants tend to be
Answer:
The statement is true
Explanation:
The Gibbs free energy is defined as:
ΔG = ΔH - TΔS
Where ΔH : Change in the enthalpy
T : The temperature
ΔS : Change in the entropy
And the Gibbs free energy is a thermodynamic potential that can be used to calculate the maximum of reversible work that may be performed by a thermodynamic system at a constant temperature and pressure.
If the thermodynamic process is isothermal and isobaric, then the statement is true.
Without friction, the amount of work only depends on the final height,
and is not affected by the route used to get there.
If the ramp has no friction, then it has no effect on the total amount
of work done. The work to lift the load straight up is the same.
If the ramp has some friction, then it takes more work to use the ramp
than to lift the load straight up. Then the work to lift the load straight up
would be less than when the ramp is used.
