Answer:
<h2>a. 1000 X 2^8</h2>
Explanation:
As given;
Initial population of bacteria= 1000;
Log phase growth is exponential phase, period in which bacteria gets double.
Generation time= 15 minutes;
it means, bacteria get double in every 15 minute,
so after 2 hours, bacteria will have 8 generation times;
so the final generation of bacteria is =1000 X 2^8.
Final bacterial generation after two hours = 256,000(1000 X 2^8)
Answer:
The pitch is the independent variable.
The dogs are the dependent variable.
Explanation:
An independent variable is something that you can control such as how high or low the pitch is. The dependent variable is the variable that is dependent on the independent variable. The dependent variable is the one that shows the results.
Answer:
As a cell grows bigger, its internal volume enlarges and the cell membrane expands. Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.
