A hypotonic solution will have a higher water potential than the red blood cells, causing water to go into the cells, making them swell up or even burst.
The two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner.
Answer;
C) xylem and phloem
Explanation;
-Both Xylem and phloem are referred to as vascular tissue, they play an important role in higher plants, which is mainly transportation of materials through out them. They allow inter-cellular communication through transportation of substances in higher plants.
-Xylem transports water and solutes from the roots to the leaves, phloem transports food from the leaves to the rest of the plant .Phloem is responsible for the transport of sugars from source tissues (photosynthetic leaves) to other tissues of the plant (non-photosynthetic).
Answer:
A.it pumps hydrogen ions inside the cell
Explanation:
Principally, the main role of electron transport chain is to maintain the electrochemical gradient of hydrogen ions (H+) inside the mitochondrial matrix. This is the last step in aerobic cellular respiration and performs a series of redox reactions. Overall, it allows accumulation of H+ inside the mitchondrial matrix. This increased gradient or accumulation of hydrogen ions (H+) is essential because H+ would accept the electrons producing during the reactions. Without this, the flow of electron will be stopped because of high gradient, and production of ATP will not happen as well.
Indeed ETC helps in production of ATP but that is not the main function of electron transport chain rather it is a function of mitochondria.
