Explanation:
Melanin is the pigment which absorbs UV light and it is present in skin and gives black colour to it.As we can see africans usually have black skin as they have to face direct uv light.
Answer:
The overall (unbalanced) chemical equation for cellular respiration is: C6H12O6+O2→CO2+H2O+energy.
The right answer is reticulocyte.
The reticulocyte is the cell preceding the erythrocyte stage in erythropoiesis. He is almost like her.
Reticulocytes are young red blood cells that still have ribosomes and mitochondria, but no peroxisomes. They are therefore capable of a fairly intense metabolism and they still actively synthesize hemoglobin.
Because the chain will begin to shut down and will no longer pump [H+] (hydrogen ions) across the membrane; thus, the proton gradient can not be maintained.
:) I hope this answers your question!
