Answer:
I think the full question is this:
The pH indicator bromothymol blue is blue in an alkaline solution and yellow in an acidic solution. A slight increase in acidity, such as when CO2 gas is added, causes a solution with the indicator to change from blue to yellow. A solution with the indicator would be most likely to turn from yellow to blue when which combination of factors exists? A. Yeast cells and sugar are placed in the solution. B. Water plants in the solution are placed under a bright lamp. C. Algae are placed in the solution and left in a dark room. D. A person blows air into the solution through a straw.
Answer is option B
B. Water plants in the solution are placed under a bright lamp.
Explanation:
When CO2 gas was added, it causes a solution with the indicator to change from blue to yellow. A combination of factors that can cause this solution to change from the yellow to its initial blue colour is utilizing a photosynthetic organism which in the presence of light can utilize and remove these carbondioxide and revert the yellow colour of the solution to blue
Thus, water plants in the solution are placed under a bright lamp
Algae are placed in the solution and left in a room filled with light
Answer: The answer is C
Explanation:
After each PCR cycle, the amount of DNA does not increase in a linear manner
Answer:
The Inter-Tropical Convergence Zone (ITCZ)region gets the most direct sunlight at any given period in time. This in turn causes air to be unstable with a drop in pressure and rise of air which cools and condenses into clouds to form precipitation causing the wet season in the tropics.
In this region, the sun is directly or almost overhead as seen during summer periods in the tropics.
Only in areas of the North and South of the ITCZ known as doldrums which at times are parallel to the ITCZ do we have high pressure that aren't conducive to precipitation causing dry season in the tropics.
In the ITCZ zone, we also have the tropical rain forests along the equator with huge amount of all round rain for the year.
Along the equator, on either side of the rain forests we have the dry and wet forests with the savannah to the North of this region and the southern hemisphere to the south of these forests since these forests are seen mostly in the ITCZ than the savannahs.
Rain shadows and ocean cueeebts may at times cause some savannahs to be along the equator and some rain forests -wet and dry forests- to be positioned further form the equator.
