What should be your response as you approach a roundabout?
BigorU [14]
<span>The correct answer is B) choose the correct lane. It is always important when driving to ensure you are in the correct lane, but in roundabouts, it is essential to the traffic flow. Choice A is not correct because roundabouts are designed to slow down traffic and you need to be paying attention to what is going on and slowing down before you enter. Choice C is not correct because you do not have the right-of-way; the traffic already in the roundabout does and you would need to yield to them. Choice D is not correct because choices A and C are not correct.</span>

1. Define fitness as it used to describe adaptation
aliya0001 [1]

Answer:

In terms of adaptation, fitness refers to the ability of an organism to survive and reproduce in a constantly changing environment.

Adaptive traits are very much important in a constantly changing environment as they increase the chances of survival of a population in the environment.

For example, Darwin's finches adapted to develop different types of beaks in order to get nutrition in different environments. Long necks of giraffes are also considered as a result of adaptation which helps them get the food located high on trees.

define amphibian ?

Amphibians are four-limbed, ectothermic animals that belong to the class Amphibia. The phylum Lissamphibia includes every extant amphibian. They live in a broad range of habitats, with the majority of species being found in freshwater aquatic, terrestrial, fossorial, or arboreal settings. Therefore, amphibians normally begin their lives as aquatic larvae, but certain species have evolved behavioural adaptations to get around this.

The young typically transition from a larval stage with gills to an adult form with lungs. Some tiny terrestrial salamanders and frogs rely solely on their skin for respiration, whereas amphibians use their skin as a supplementary respiratory surface. Although they resemble lizards on the surface, reptiles, like mammals and birds, are amniotes and do not need bodies of water to survive.
