European rabbits were introduced to Australia in 1859. The rabbits reproduced rapidly in their new environment, displaced other
Goryan [66]

Answer:

B) Natural selection favored rabbits that were resistant to the virus

Explanation:

Most likely, virus resistance occurred over time, as a consequence of mutation. Individuals that carried the resistance mutation become favourable by natural selection.

Natural selection is evolutionary mechanism which favours traits of an organism that help him survive and reproduce (increase organism's fitness). In the example above, resistant rabbits that survived had the favorable trait (resistance) by natural selection.

Answer:

OH LOL I DID THIS IN 7TH GRADE

Explanation:

so if i remember when the trees where white the pepper moths that where white survived more often that the black ones, then when the industrial war came the trees where covered in ash, so the white moths survived

MY SENTENCE

It shows how a change in an environment can effect a species natural selection, for example the white moths survived more than the black moths so the reproduced while the black moths where eaten by predator's, then when the environment changed and favored the black moths they survived and reproduced while the white moth got picked off by predators.

Hope this helped mate :>

If a mouse and a small lizard of the same mass (both at rest) were placed in experimental chambers under identical environmental
Harman [31]

The mouse, because it is an endotherm and therefore its basal metabolic rate is higher than the ectotherm lizard's standard metabolic rate.

<h3>What are endotherms and ectotherms?</h3>

Animals classified as ectotherms and endotherms employ several techniques to control body temperature.

Endotherms are recognized as warm-blooded creatures, whereas ectotherms are also referred to as cold-blooded creatures. Ectotherms and endotherms vary primarily in that endotherms control their body temperatures by sustaining bodily functions, but ectotherms depend on external sources like sunlight to do so. Ectotherms include invertebrates, fish, amphibians, and reptiles while endotherms include mammals and birds.
