The carrying capacity of any individual biological species is the maximum size of the population which can sustain indefinitely in that environment provided the necessary requirements like food, water and other environmental conditions are available.
The carrying capacity in the graph is the point on the graph where the line of population is horizontal. The graph has the population in y-axis and time period on x-axis. Alternatively if in the carrying capacity graph the line becomes parallel to x axis then it gives the carrying capacity. Here, at the point 2000 on y-axis and starting from 15 months in x-axis is the point of carrying capacity is marked with red horizontal line and green border in the image attached.
True I had this on a test and I got 100 YOU GOT THIS
Answer:
The CRA-cAMP complex increases the rate of expression of lac operon when glucose is absent and lactose is present as nutrient.
Explanation:
CRP is the catabolite gene activator protein that forms a complex with cAMP. The CRP-cAMP complex facilitates the binding of RNA polymerase to the promoter region of the lac operon. This robust binding as stimulated by CRP-cAMP complex is followed by the formation of open complex and initiation of gene expression.
Hence, the CRP-cAMP complex positively regulates the lac operon and increases its expression when glucose is not present.
Light will increase the rate of photosynthesis, should be reflected in the rate of disk rising
- no disks should rise in dark since photosynthesis requires light
