Answer:
125.6
Explanation:
Area of a circle = πr^2
Area of circle 1 = 3.14 × 11 × 11
=379.94cm^2
Area of circle 2= 3.14 × 9 ×9
=254.64cm^2
Area of a shaded region
=379.94cm^2 - 254.64cm^2
=125.60cm^2
B. ATP synthase. The purpose of the hydrogen gradient is to take advantage of molecules' tendency to move from areas of higher concentration to areas of lower concentration. ATP synthase lets hydrogen ions flow through it to the matrix, and the energy from this flow is used by ATP synthase to synthesize ATP.
A rabbit is a consumer because it gets its energy from eating other living organisms. A fungus is a decomposer because it gets its energy from breaking down the material of dead organisms or their products.
All of the above.
<h3>What are sulfur oxidizing bacteria?</h3>
Any of a wide range of microorganisms that can metabolize sulfur and its components and are significant in nature's sulfur cycle are known as sulfur bacteria. Hydrogen sulfide (H2S), sulfur, and thiosulfate are a few of the typical sulfur compounds that are used by these bacteria as a source of energy. Sulfate is the end result of the oxidation of sulfur.
In deep earth deposits, <em>Thiobacillus</em>, which is common in both marine and terrestrial settings, produces sulfuric acid, which dissolves metals in mines but also corrodes concrete and steel. It also oxidizes sulfur, generating sulfates that are helpful to plants.
I understand the question you are looking for is this:
In seawater, sulfate is the most common anion after chloride. Which of the following is correct with respect to the use of sulfate by some bacterial groups?
- Oxidized sulfur-containing molecules have redox potentials lower than those of the nitrogen series.
- Oxidized sulfur molecules such as sulfate and sulfite serve as electron acceptors.
- Sulfate and sulfite can receive electrons from hydrocarbons.
- Sulfate-reducing archaea and bacteria are widespread in the ocean.
- All of the above.
