Answer:
A
Explanation:
With chemical reactions, there are various factors that affect the rate of the reaction. One of these is temperature.
When you raise the temperature, the reaction will move faster. Why? Temperature is directly correlated with the kinetic energy (basically, the energy that makes the particles move). Higher temperatures mean higher kinetic energies. Particles with higher kinetic energies move faster, which makes them more likely to collide. When collisions occur more frequently, the reaction follows through more quickly.
Thus, when Julissa warms the solutions, she will see that bubbling and white solid formation (the products of the reaction) occus faster. So, the answer is A.

<u>Answer:</u> The correct answer is False.
<u>Explanation:</u>
A magnet has two poles defined as a north pole and a south pole.
When two same poles come closer to each other, they tend to repel each other and when two opposite poles come closer to each other, they tend to attract each other.
So, when north pole comes near to another north pole, they will repel each other while when north pole comes near to the south pole, they attract each other.
Hence, the above statement is False.
Answer:
The nitrogen cycle is a cycle by which the nitrogen is converted into forms which are utilized by the living organisms and these forms circulates among the atmosphere, biosphere, and marine ecosystem. The conversion of nitrogen is through biological and physical processes.
Nitrogen Fixation is the first step in nitrogen cycle. It involves the conversion of atmospheric nitrogen into ammonia. This is done by bacteria like Azotobacter and Rhizobium.
Assimilation involves the absorption of ammonia by the plants from the soil.
Ammonification is the process by which the dead organic remains of plants and animals are decomposed by the soil bacteria to produce ammonia.
Nitrification is the process in which the ammonia is converted into nitrates by the soil bacteria Nitrosomonas and Nitrococcus. The nitrates are again converted into nitrites by the bacteria Nitrobacter.
On the basis of above description, the following is the match of steps of the nitrogen cycle.
A. Nitrification - bacteria convert nitrates into nitrogen gas.
D. Assimilation - plants and animals take in and use nitrogen compounds.
E. Denitrification - bacteria break down waste products and return nitrogen to the soil.
B. Nitrogen fixation - bacteria convert atmospheric nitrogen to ammonia.
C. Ammonification - bacteria convert ammonia to nitrites and nitrates
Answer:
Radiation-induced Luekimia
Explanation:
They worked with many radioactive elements, so it caused Leukemia which is
a disease in which the bone marrow and other blood-forming organs produce increased numbers of immature or abnormal leukocytes.
