Q: Answer the following question given this paragraph: water. Sulfur, critical to the 3D folding of proteins (as in disulfide binding), is released into the atmosphere by the burning of fossil fuels, such as coal. The cycling of these elements is interconnected. For example, the movement of water is critical for the leaching of nitrogen and phosphate into rivers, lakes, and oceans. Furthermore, the ocean itself is a major reservoir for carbon. Thus, mineral nutrients are cycled, either rapidly or slowly, through the entire biosphere, from one living organism to another, and between the biotic and abiotic world. Q: What element is released into the atmosphere by the burning of fossil fuels? A: | OPTIONS:
- carbon
- helium
- oxygen
- sulfur
A: sulfur

Q: Answer the following question given this paragraph: The strong nuclear force is a force of attraction between fundamental particles called quarks, which have a type of charge called color charge. The strong nuclear force is transferred between quarks by fundamental force-carrying particles called gluons. Both protons and neutrons consist of quarks. The exchange of gluons holds quarks together within a proton or neutron. Excess, or residual, strong force holds together protons and neutrons in the nucleus. The strong nuclear force is strong enough to overcome the electromagnetic force of repulsion pushing protons apart. Both forces are represented in the Figure below . Q: What is the force of attraction between fundamental particles called quarks, called. A: | OPTIONS:
- magnetism
- gravity
- weak nuclear force
- strong nuclear force
A: strong nuclear force

Q: Answer the following question given this paragraph: Chloroplasts Like the mitochondria, chloroplasts have their own DNA and ribosomes, but chloroplasts have an entirely different function. Chloroplasts are plant cell organelles that carry out photosynthesis. Photosynthesis is the series of reactions that use carbon dioxide, water, and light energy to make glucose and oxygen. This is a major difference between plants and animals; plants (autotrophs) are able to make their own food, like sugars, while animals (heterotrophs) must ingest their food. Like mitochondria, chloroplasts have outer and inner membranes, but within the space enclosed by a chloroplast's inner membrane is a set of interconnected and stacked fluid-filled membrane sacs called thylakoids ( Figure 4.17). Each stack of thylakoids is called a granum (plural = grana). The fluid enclosed by the inner membrane that surrounds the grana is called the stroma. Q: Like the mitochondria, chloroplasts have their own dna and ribosomes, but chloroplasts have an entirely different function. chloroplasts are plant cell organelles that carry out what? A: | OPTIONS:
- reproduction
- digestion
- growth
- photosynthesis
A: photosynthesis
