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.

Answer:

social facilitation

Explanation:

The concept of social facilitation was first proposed by Norman Triplett. After observing a cycling event, in which he noticed that cyclist performed better when they have others around competing with them, rather than cycling alone just against time. This led him to duct an experiment where he gave some children strings to wound fishing reel. He observed that, children wound the fishing reel faster in the presence of other children performing similar task, when compared to when perform such task alone.

This concept discovered by Norman Triplett, best illustrates the concept of social facilitation, which posits that, individuals tend to perform better in the mere presence of others or when they perform a task with others, than when performing the task alone.

*<br> 1. In the water cycle, water goes from a liquid to a gas during which stage?
Ira Lisetskai [31]

Answer:Evaporation Evaporation is simply the process by which liquid turns into a gas. Water (a liquid) turns into vapor (a gas) when heat energy is applied to raise its temperature to 100°C (212°F). Water in the liquid state is a compound, and the heat breaks up the bonds into water molecules, which is gaseous.
