Answer:
A. 
B. 
C. 
D. 
Explanation:
Hello.
In this case, we must compute the final concentration in all the cases so we solve for it in the given equation:
Thus, we proceed as follows:
A. Here, the final diluted solution includes the 300 μL of the 5 mg/ml-BSA and the 700 μL of TBS.
B. Here, the final diluted solution includes the 50 μL of the 1.5 mg/ml-BSA, the 450 μL of water and the 500 μL of TBS.
C. Here, the final diluted solution includes the 10 μL of the 1 mg/ml-BSA and the 990 μL of TBS.
D. Here, the final diluted solution includes the 10 μL of the 0.1 mg/ml-BSA and the 990 μL of TBS.
Best regards.
Answer;
D. The birds have different mating seasons.
Explanation;
-Different species of birds have different mating or breeding seasons. Evolution has played a role in adjusting the timing of avian(birds) breeding seasons to maximize the number of young produced. The breeding season depends on a number of factors, for example In the temperate, subarctic, and arctic zones, the overriding factor is the availability of food. This varies across all different species of birds, irrespective of other similarities they may have.
An environmental scientist might study the effect of soil pollution on plant growth. This is true.
Hope this helped :)
<span>Since we are not able to get energy directly from the food we eat, a particular process needs to take place that converts molecules to Adenosine triphosphate, also known as ATP. This requires that the food first be broken down by being digested. As digestion takes place, the body uses the small molecules to make ATP.</span>
The answer is underwater eathquakes.
Earthquakes are a shaking of the ground that when observed on earth, can cause many damages mainly on hills and mountainsides causing avalanches. When they occur underwater though, the water gets lifted (normally from the sea) and generates giant waves that can sometimes reach the coast.
