Given parameters:
Velocity of the car = 5m/s North
Time = 9s
Unknown:
Displacement of the car = ?
Solution:
Displacement is the distance traveled in a specific direction. It is a vector quantity with magnitude and direction.
To find displacement use the expression below;
Displacement = Velocity x Time
Input the parameters and solve;
Displacement = 5 x 9 = 45m due North
The displacement of the car is 45m due North
Answer:
True
Explanation:
Conditions such as temperature and pH are critical for biological molecules and should be well maintained. If the pH changes in an abnormal manner then the structure of the biological molecules might change and they will not be able to perform their functions. For example, the amino acid side chains can be disturbed due to pH changes which result in the unfolding of the protein or the protein structure to get changed, As a result, the protein will not be able to carry out its function. Hence, the statement is true.
Answer:
The answer is b)Betaproteobacteria and e)Gammaproteobacteria
Explanation:
Nitrification, which is defined as the microbial oxidation of ammonia to form a nitrate, plays an important role in the global nitrogen cycle. There are two different groups of bacteria that can oxidize ammonia, as a first step in the nitrogen cycle. These groups are known as the Beta-proteobacteria (genera <em>Nitrosomonas</em> and <em>Nitrosaspira</em>) and the Gamma-proteobacteria (genus <em>Nitrosococcus</em>).
