blondinia [14]

Answer:

The resistance of the device is 27Ω

Explanation:

When a device is used in a circuit in which the voltage is 81 V, the current flowing through the device is 3 A.

In order to calculate the resistance of the device, we know that the resistance is directly proportional to the voltage in the terminals of the device and the current flowing through it.

Using Ohm's law

R=\frac{V}{I} \\R=\frac{81V}{3A}=27Ω

Two species of warblers colonize the same island habitat. Both species nest in similar locations and eat the same type of prey.
GuDViN [60]

Answer:

D. Be eliminated

Explanation:

Competition in biology is the process of interaction between two or more organisms, which are using the same resources e.g food, space, mate or occupying the same ecological niche. Competition between organisms often result in one or bother organisms getting harmed due to the strive for a limited resource.

Organisms can adapt to their environment within one generation
bezimeni [28]

Answer:

Organisms can adapt to their environment within one generation if they are selected naturally by the nature.

Explanation:

Organisms can survived which can withstand or tolerate the harsh climate of the environment while some organisms removed from that environment due to low survival ability in that harsh climate. This selection is done by nature in which well suited animals and plants can survive in that environment due to certain adaptations. Those organisms can adapt to their environment within one generation due to survival ability and high fitness.

For example, in deserts, bears did not survive because it requires cold climate so only reptiles such as snakes and lizards can survive in this environment.
