Answer:
Option (4) Second gap, is the correct answer.
Explanation:
G2 phase is the third phase of inter-phase. Second gap is also called G2 phase. It is a phase of the cell cycle which comes before the prophase stage of mitosis. In this phase, proteins are synthesized by the cell and increase occurs in the size of protein. In this phase, cell size is also increased and the cell is ready for mitosis.
A spontaneous reaction is one that favors the creation of products under the reaction's current conditions.
What is spontaneous reaction?
A spontaneous reaction is exergonic and has a negative delta G. The system's enthalpy, or total energy, must decrease and its entropy, or disorder, must rise for a chemical reaction to occur with a net release of free energy (- delta G). The energy needed for cellular function comes from spontaneous reactions.
What is importance of spontaneous reactions in the metabolism of a cell?
- Chemical reactions take place in steps to produce and break down complex molecules as part of cellular activities.
- While some of these chemical processes take energy to complete, others happen spontaneously and release energy.
- Cells must continuously produce additional energy to replace the energy spent by the numerous energy-intensive chemical reactions that take place all the time, just as living beings must continuously consume food to replenish their energy stores.
- The term "cell metabolism" refers to all of the chemical processes that occur within of cells, including those that use or produce energy.

Explanation:
the entire population will go extinct
Answer: 25% of the children will have both anirida and migraine headache
Explanation: The man has a dominant gene for anirida and normal headache with a mom with no blindness. Therefore, the man gene is (Nn) for heterozygous anirida and (mm) for normal headaches and his wife has heterozygous gene for migraine (Mm) 'cause her dad has normal headache and homozygous gene for normal vision(nn) .
Therefore
Nnmm × Mmnn= NnMm Nnmm Nnmm nnmm.
The crossing would give birth to Offspring with nirida and migraine (NnMm) =1/4 ×100= 25%
