Answer:
Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.

Explanation:
Cat and dog both are domestic animals but the can not interbreed to produce fertile offspring. Specie is define as those animal which can interbreed to produce fertile offspring so the cat and dog can not interbreed as they belong to two different species. Both species have different <u>chromosome number</u> that's why the can not interbreed. In order to interbreed both the organisms must belong to one specie. E.g As both tiger and lion live in one environment and the interbreed and produce tiglion but it is infertile and can not breed to produce offspring.
Answer:
D) It would contain less nitrogen.
Explanation:
In an investigation of the cycling of environmental gases, a student placed water and bromthymol blue in each of four test tubes as shown in the diagrams below. No additional items were placed in tube 1, a snail was placed in tube 2, an aquatic plant (elodea) was placed in tube 3, and both a snail and an elodea were placed in tube 4. The tubes were then stoppered and placed in bright light for 24 hours. The solution in tube 3 changes after 24 hours because it would contain less nitrogen.
The dfferent tubes are shown in the picture that I uploaded.
