A group of students conducted the following experiment. In test tube 1, students placed one snail. In test tube 2, they placed one snail and one plant. Both test tubes were sealed closed so that no additional gases, such as oxygen, could enter or leave the test tubes. The students monitored the level of carbon dioxide in both test tubes for one hour. At the end of one hour, students observed that the level of carbon dioxide increased in test tube 1 but remained consistent in test tube 2. Which of the following statements best explains the difference in the carbon dioxide levels observed between the two test tubes?

Answers

Answer 1

An aquatic green plant was placed into each test tube, and the tubes were corked. One tube was placed in the dark, and one was placed in direct sunlight.

What is carbon dioxide ?

One carbon atom is covalently doubly linked to two oxygen atoms in each of the molecules that make up carbon dioxide. At room temperature, it exists as a gas. In the atmosphere, carbon dioxide serves as a greenhouse gas because it absorbs infrared radiation despite being transparent to visible light. It has increased from pre-industrial levels of 280 ppm to a trace gas in the Earth's atmosphere at 421 parts per million (ppm), or roughly 0.04% by volume (as of May 2022). The fundamental driver of both these elevated CO2 concentrations and climate change is the burning of fossil fuels.   Groundwater, lakes, ice caps, and ocean all contain dissolved carbon dioxide.

False. The credibility of a noncredible person is unlikely to increase over time, as people are likely to remember the reason for discounting it in the first place.

The Unlikelihood of Increasing the Credibility of a Noncredible Person

The credibility of a noncredible person is unlikely to increase over time, as memories are persistent, and people tend to remember the reasons for discounting the person's message. Furthermore, a person who is not credible will struggle to build trust and credibility, as people will be hesitant to believe anything they say in the future.

Cultural elements include things like laws, traditions, dress codes, and architectural designs.

In addition to the social behaviour, structures, and conventions that define human societies, a comprehensive definition of culture encompasses knowledge, beliefs, the arts, laws, customs, and habits of the people who belong to these groups. Culture typically begins or is attributed to a specific region or location. The diversity of cultures found in many civilizations is evidence that humans acquire cultural knowledge through enculturation and socialization. A cultural norm codifies acceptable behaviour in society; it acts as a model for expected social behaviour in a group by providing guidelines for behaviour, attire, language, and mood in a scenario. Accepting a monoculture in a social group poses risks, much as a single species could wither in the face of environmental change due to a lack of functional responses.
