Answer: Protons
Explanation: Every atom is defined by its protons every element. So if it has 1 proton its hydrogen no matter what. If it has 2 protons its helium no matter what and so on. So if you know the number of protons you know the element.
The atomic number tells you the number of protons that are in the core of a particular element.

Answer:
The blanks will be filled by following words - inside, open
Explanation:
The sentence in the question tells about the mechanism of closing of stomata in plant cells and the role of potassium ions in closure of stomata. The completed statement will be -
Potassium ions are actively pumped out of the guard cells. When K are pumped in, the inside of the cell is hypertonic relative to the outside of the cell that is hypotonic. Subsequently, water moves <u>inside</u> the guard cells, the guard cells bulge and the stomata <u>open</u>.
Answer:
2, 3, 4, 1
Explanation:
Inversion of DNA sequences refers to the rearrangement of the sequences where a segment is reversed end to end.
For instance in order for the gene of species to have the sequence STUVWX
The order of evolution will be
- sequence UVXTSW will be the first sequence
When XTSW segment is inverted WSTX
- sequence UVWSTX will be the result of the inversion.
section UVWS is inverted to SWVU
- sequence SWVUTX is formed.
when WVUT undergoes inversion to TUVW
- It becomes the original arrangement of STUVWX .
