Answer:
The electron transport chain may be defined as the sequential steps of the oxidation and reduction of the cytochromes. The electron transport chain is important for the production of ATP.
The gramicidn protein is an ionophoric antibiotic that can affect the electron transport system. The electron transport rate, oxygen uptake and proton pumping remains the same as more hydrogen ions will enter in the cell. But the ATP synthesis rate might decrease and completely stop by using gramicidin.
Answer: true
Explanation: In gel electrophoresis, the smaller the size/molecular weight of DNA the faster it moves across the gel and vise versa. This is as a result of the pore size of the gel which is usually prepared 1g of agarose in 100ml of distilled water. So a DNA fragment with 1000 base pairs will "struggle" its movement across the gel pore making it mive less faster and further. Movement and molecular weight of DNA are inversely proportional.
A solstice can be two things, the summer solstice and the winter solstice. it's when the sun reaches its highest or lowest point in the sky at noon, marked by the longest and shortest days. however, an eclipse is when the earth, moon and sun align together blocking the sun's light which is why it's called an eclipse because it means hiding/blocking. :)
