Answer:
option d Meiosis
Explanation:
Term Meaning
Gamete A sex cell (in humans: sperm for males, and eggs for females)
Meiosis A two-step process of cell division that is used to make gametes (sex cells)
Crossing over Process in which homologous chromosomes trade parts
Interphase Phase of the cell cycle where the cell grows and makes a copy of its DNA
Homologous chromosomes Set of chromosomes (one from each parent), that are very similar to one another and have the same size/shape
Sister chromatids Two halves of a duplicated chromosome
Diploid (2n) Cell that contains two sets of homologous chromosomes
Haploid (n) Cell that contains only a single set of genes
Meiosis
The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).
Stages of meiosis
Meiosis contains two separate cell divisions, meaning that one parent cell can produce four gametes (eggs in females, sperm in males). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

GOLD IN THE SKY
By Alan E. Nourse
Chapter 1. Trouble Times Two
The sun was glowing dull red as it slipped down behind the curving horizon of Mars, but Gregory Hunter was not able to see it.
There was no viewscreen in the ship's cabin; it was too tiny for that. Greg twisted around in the cockpit that had been built just big enough to hold him, and shifted his long legs against the brace-webbing, trying to get them comfortable.
He knew he was afraid ... but nobody else knew that, not even the captain waiting at the control board on the satellite, and in spite of the fear Greg Hunter would not have traded places at this moment with anyone else in the universe.
He had worked too hard and waited too long for this moment.
He heard the count-down monitor clicking in his ears, and his hands clenched into fists. How far from Mars would he be 10 minutes from now? He didn't know. Farther than any man had ever traveled before in the space of 10 minutes, he knew, and faster. How far and how fast would depend on him alone.
"All set, Greg?" It was the captain's voice in the earphones.
"All set, Captain."
"You understand the program?"
Greg nodded. "24 hours out, 24 hours back, 90 degrees to the ecliptic1, and all the acceleration2 I can stand both ways."
Greg grinned to himself. He thought of the months of conditioning he had gone through to prepare for this run ... the hours in the centrifuge to build up his tolerance to acceleration, the careful diet, the rigorous hours of physical conditioning. It was only one experiment, one tiny step in the work that could someday give men the stars, but to Gregory Hunter at this moment it was everything.
"Good luck, then." The captain cut off, and the blastoff buzzer sounded.
He was off. His heart hammered in his throat, and his eyes ached fiercely, but he paid no attention. His finger crept to the air-speed indicator, then to the cut-off switch. When the pressure became too great, when he began to black out, he would press it.
But not yet. It was speed they wanted; they had to know how much acceleration a man could take for how long and still survive, and now it was up to him to show them.
Fleetingly, he thought of Tom ... poor old stick-in-the-mud Tom, working away in his grubby little Mars-bound laboratory, watching bacteria grow. Tom could never have qualified for a job like this. Tom couldn't even go into free-fall for 10 minutes without getting sick all over the place. Greg felt a surge of pity for his brother, and then a twinge of malicious anticipation. Wait until Tom heard the reports on this run! It was all right to spend your time poking around with bottles and test tubes if you couldn't do anything else, but it took something special to pilot an XP ship for Project Star-Jump. And after this run was over, even Tom would have to admit it....
There was a lurch, and quite suddenly the enormous pressure was gone.
Something was wrong. He hadn't pushed the cut-off button, yet the ship's engines were suddenly silent. He jabbed at the power switch. Nothing happened. Then the side-jets sputted, and he was slammed sideways into the cot.
He snapped on the radio speaker. "Control ... can you hear me? Something's gone wrong out here...."

Answers
We can see in the story that the setting is in a cockpit, in a lab, simulating a landing to Mars because of this paragraph; "Greg twisted around in the cockpit that had been built just big enough to hold him, and shifted his long legs against the brace-webbing, trying to get them comfortable." We can see that Greg Hunter is nervous, "His heart hammered in his throat, and his eyes ached fiercely, but he paid no attention. His finger crept to the air-speed indicator, then to the cut-off switch." The time period we can state is around the 1950s. It implied the first trip to Mars, "He heard the count-down monitor clicking in his ears, and his hands clenched into fists. How far from Mars would he be 10 minutes from now?" In conclusion, the time is believed to be sometime in the 1950s, and the setting is in a lab where Gregory Hunter is going on a trip to mars when something wrong has happened.
The paragraph that presents the training that Greg underwent to participate in this mission shows that he is very determined and dedicated to the research he is part of. This is the detail capable of creating the character.
This paragraph is:
"Greg grinned to himself. He thought of the months of conditioning he had gone through to prepare for this run ... the hours in the centrifuge to build up his tolerance to acceleration, the careful diet, the rigorous hours of physical conditioning. It was only one experiment, one tiny step in the work that could someday give men the stars, but to Gregory Hunter at this moment it was everything."
We can reach this answer because:
The text shows that Greg is a scientist who is participating in research on Mars.This research includes a mission to Mars, which is very dangerous and very demanding on him.Despite the fear and uncertainty, the text shows that Greg was very dedicated to this, going through heavy and challenging training.These details help build a dedicated, courageous, and determined character to achieve their goals. We can even see Greg as a complex character, because of his nuances.
