It oxidies iron and inorganic sulfur compounds. The oxidation process can be harmful, as it produces sulfuric acid, which is a major pollutant. It has been suggested that T. ferrooxidans forms a symbiotic relationship with members of the genus Acidiphilium, a bacterial capable of iron reduction. Other species of Thiobacillus grow in water and sediment; there are both freshwater and marine strains.
The bacteria are usually found in rivers, canals, mine drainage effluents and mining areas. So there may be some source of these bacilli near their house.They require inorganic sources to grow and contain an enzyme called ferrous oxidase that allows them to metabolize iron.
<span>They eat iron pipes corroding the pipes leading into households and produce a thick slime layer biofilm.</span>
I don’t think we would have the same countries. i feel like everything would be connected, like maybe a few really big countries instead of hundreds of different countries. i feel we would look different that how we already look because there would be more of different type of people around each other, resulting in mixed race reproducing.
Answer:
A) polar
Explanation:
Polar molecules contains partial positive and partial negative charge as in all polar molecules two atoms have unequal sharing electron. Due to unequal sharing of electrons, one atom that attracts valence electrons strongly gains positive charge and other gain negative charge.
For example water, water is a polar molecule having partial negative and partial positive charge because the oxygen atom in water attracts electrons more strongly than the hydrogen atoms.
Hence, the correct answer is "A) polar".
- The independent variables are temperature, airflow, and light and the dependent variable in each of the experiments is evaporation.
- The schematic representation in the diagram helps in the understanding of the setup for the experiments.
- The level of temperature, the rate of airflow, and the intensity of light must be controlled in the experiments.
- A person will not be confident in experiment 3 results as the temperature is the independent variable that alters the results of evaporation.
<h3>What are the four foremost factors of a managed test?</h3>
When possible, scientists take a look at their hypotheses through the use of managed experiments. A managed test is a systematic take look at executed below-managed conditions, which means that simply one (or a few) elements are modified at a time, even as all others are saved consistently. We'll appear carefully at managed experiments within side the subsequent section.
- In the three experiments, the dependent variable is evaporation, as it changes with the change in another variable.
The independent variable in experiment 1 is temperature, experiment 2 is airflow, and experiment 3 is light.
- The experiment can be understood better with the representation of the schematic that shows the setup to analyze how the experiment was performed. Therefore the diagram must add the schematic of the experiment.
- The controlled items in the experiment are the variables that are set at the particular unit to form the result. the controlled item in experiment 1 is temperature, experiment 2 is airflow from the fan, and experiment 3 is the intensity of light.
- The result of experiment 3 is based on the dependence on the intensity of light keeping temperature constant and controlled. If the temperature is not controlled in the experiment then it may lead to an alteration in the results as it depends on both light and temperature.
- The flow chart for the increase in pressure affecting the evaporation is given in the image attached.
