Answer:
Explanation:
Although protons resemble other positive ions such as Na+ and K+ in their movement across membranes, in some respects they are unique. Hydrogen atoms are by far the most abundant type of atom in living organisms; they are plentiful not only in all carbon-containing biological molecules, but also in the water molecules that surround them. The protons in water are highly mobile, flickering through the hydrogen-bonded network of water molecules by rapidly dissociating from one water molecule to associate with its neighbor, Protons are thought to move across a protein pump embedded in a lipid bilayer in a similar way: they transfer from one amino acid side chain to another, following a special channel through the protein.
"F many scientists conduct the same or similar experiments, and all obtain similar results a 'Scientific Law or Theory' can be written, which is a generally agreed-upon statement that explains and predicts how a natural phenomenon works
The study of onion root tips is widely known for the clear appearance of the stages of mitosis since the chromosomes are large and are clearly visible. They are easily stained with the stainer and are visible clearly under the electron microscope. The phase of mitosis are
Interphase
Prophase
Metaphase
Anaphase
Telophase and
Cytokinesis
Each of these phases show the different stages in which the division of one cell into two daughter cells takes place. The cytokinesis is the final phase in the mitosis cell division. This is the part of cell division process during which the cytoplasm of the cell divides into two equal parts and forms into two daughter cells.
During the cytokinesis process, the spindle apparatus partitions and transports the duplicated chromatids and moves into the cytoplasm of the dividing daughter cells. In this process a dividing structure called the cell plate is formed to distinguish the daughter cells. This cell plate later grows into a double layered cell wall which then splits the parent cell into two separate cells.
Hence the option D is the right answer
Answer:
I assume there could be a change in water vapour in the weather as the coldness and the clouds in the city of Mark will transform into ice and fall like snow. And it is really warm in the town of Vikki, and the vapour of water may fall as rain.
