<span>Oogenesis is the creation of the female gamete and spermatogenesis is the creation of the male gamete.
Meiosis begins in male once they reach puberty (they do both meiosis I and II) and do it for the rest of their lives non-stop
Females begin Meiosis I in the womb and they don't start to do Meiosis II until they reach puberty. Unlike males, females don't form gametes non stop and they stop forming gametes at menopause.
The end result for males are four sperm cells
For females, they create three small polar bodies and one big daughter cell. The polar bodies give themselves up and give their nutrients to the big cell. So for females, they create only one gamete while males create four.

Answer:
Check Explanation.
Explanation:
So, the question is about a research or an experiment on whether the intake of cola causes a lot of or severe headaches. And I will be using myself as the control experiment. Please note that I just did not want to use myself as the control experiment but because the question ask us to. That is the use of "single case design" which means that the person performing the experiment must use himself or herself as the control experiment instead of using another person.
Step one => I will make sure to know how often or how many times I do do get headaches.
Step two => I will then stop taking the cola, but after sometimes I will continue taking the cola back.
Using the single case design, I can test for my Hypothesis using the following steps;
For step two above, if during the period that I stopped taking cola, I did not have any headache and immediately I start taking the cola I started developing headaches, then
it is true that the artificial sweetener in the cola is responsible for the headaches.
To the second part of the question; I expect to find that that the artificial sweetener in the cola is responsible for the headaches.
My conclusion will be that the artificial sweetener in the cola is responsible for the headaches.
The nomads used them to transport their loads and thus save themselves during desert journeys in Africa and the Middle East. Due to its endurance and ability to conserve water, the camel is the most suitable means of transport in the desert
