Answer please
Beverly Science – Nitrogen Cycle
1. What percent of the atmosphere consists of nitrogen gas? Approximately 78%.
2. Why can’t organisms use the nitrogen that is found in the atmosphere? Organisms cannot use atmospheric nitrogen (N2) directly because it is in a form that they cannot metabolize.
3. Name the vitally important organic macromolecules in which nitrogen is needed. Proteins and nucleic acids (DNA and RNA).
4. Which types of organisms perform nitrogen fixation, nitrification, ammonification, and denitrification? Nitrogen fixation is performed by nitrogen-fixing bacteria and some cyanobacteria. Nitrification is carried out by nitrifying bacteria. Ammonification is done by decomposer bacteria and fungi. Denitrification is performed by denitrifying bacteria.
5. How is denitrification different from nitrogen fixation, nitrification, or ammonification? Denitrification is the process in which nitrate (NO3-) is converted back into nitrogen gas (N2) and released back into the atmosphere. Nitrogen fixation, nitrification, and ammonification involve the conversion of atmospheric nitrogen into a form that can be used by organisms or the breakdown of organic nitrogen compounds into ammonium (NH4+).
6. What does the word assimilation mean? Assimilation refers to the incorporation of nitrogen into organic molecules by organisms. Nitrogen begins to assimilate into biological systems when it is taken up by plants or consumed by animals.
7. What is the atmospheric event that can release Nitrogen from N2 to form a bioavailable form of nitrogen? Lightning. When lightning occurs, it provides enough energy to break the strong triple bond between nitrogen atoms in the atmosphere, forming nitrogen oxides (NOx). When mixed with rain, these nitrogen oxides form nitrate ions (NO3-), which can be taken up and used by plants.
Beverly Science – Water Cycle
1. How much of the earth’s surface is covered in water? Approximately 71% of the earth's surface is covered in water.
2. Why is so much of this water not fit for consumption by living organisms? Much of the water on Earth is in the form of saltwater in the oceans, which is not suitable for consumption by most organisms due to its high salt content.
3. What are the two ways that water changes from a liquid into a gas and rises into the atmosphere? The two ways are evaporation and transpiration.
4. What is the evaporation of water from plants called? Transpiration. This water vapor gets out of the plant through small openings in the leaves called stomata.
5. Which stage of the water cycle is defined as:
a. The changing of liquid water to vapor? Evaporation.
b. The changing of water vapor to liquid? Condensation.
c. The return of atmospheric water to the earth - Precipitation.
6. What role do clouds play in the water cycle? Clouds are formed through condensation, when water vapor in the atmosphere cools and becomes liquid or solid droplets. They play a crucial role in the water cycle as they are responsible for the formation of precipitation.
7. How does precipitation occur? Precipitation occurs when water droplets or ice crystals in the clouds combine and become too heavy to stay suspended in the air. They then fall to the Earth's surface as rain, snow, sleet, or hail.
