Answer:
Cytokinesis is the process by which one cell physically separates into two daughter cells at the end of each division cycle. In metazoan cells, the division plane, termed the cell equator, is determined by microtubules of the anaphase spindle.
Explanation:
Answer:
C. Its oxidation number increases.
Explanation:
- <em><u>Oxidation is defined as the loss of electrons by an atom while reduction is the gain of electrons by an atom</u></em>.
- Atoms of elements have an oxidation number of Zero in their elemental state.
- When an atom looses electrons it undergoes oxidation and its oxidation number increases.
- For example, <em><u>an atom of sodium (Na) at its elemental state has an oxidation number of 0. When the sodium atom looses an electrons it becomes a cation, Na+, with an oxidation number of +1 , the loss of electron shows an increase in oxidation number from 0 to +1.</u></em>
Answer:
c)4 neutrons
Explanation:
The atomic mass of Lithium is 7.
we know,
atomic mass=no. of proton+ no. of neutron
So, no. of neutron = atomic mass - no. of proton=7-3=4
Note: Atomic number is the number of protons.
Hope, this helps you.
