Question

Illustration of human life cycle stages: sperm, egg, zygote, and embryo development.

Accepted Answer

Hi everyone. Let's look at the next question and the human life cycle germ cells undergo blank in order to produce hap Lloyd gametes. The two half light gametes then unite in a process called blank. When sperm and ovum unite, they form a zygote. The zygote undergoes blank to begin the development of the human embryo which eventually becomes a baby. So let's think through this process. And our answer choices we have were given mitosis, fertilization and mitosis all in different order. So fertilization I think is pretty straightforward. Most of us um find that fairly simple to remember as we call fertilization is the two gametes, egg and sperm unite the gametes. Each app Lloyd unite and you have a deployed zygote as a result. Now let's again just think through mitosis and mitosis. Do you recall which processes which and their results both start with a deployed parent cell. Okay. But mitosis Results in two identical deployed daughter cells. So mitosis is used for division and growth. I mean eventually you know the cells are going to differentiate but when we think about um say the embryo developing and growing but it sells all having the same full deployed set of chromosomes mitosis is going to be our process of growth and development aosis. We have our deployed parents though But we end up with four hap Lloyd daughter selves and in humans those are the gametes. So when we look at the first part of our question germ cells undergo blank to produce hap Lloyd gametes. Well that's got to be me aosis for part one. So we need mayo sis to be first and we only have one answer choice choice C with mayo sis in the beginning and we looked through my extra It's correct. We've got me aosis label that actually we can label them 12 and three. Up here, fertilization one mitosis two and mitosis three in the order we talked about them, mitosis must go in the first blank says the two happily gametes. Then unite. In a process called that's fertilization. We label that number one here. When sperm and ovum unite, they form a zygote. Zygote undergoes. So we said that process of growth and development without changing the amount the number of chromosomes is mitosis, which we label number two. So the correct order should be mitosis fertilization mitosis and that's what we have for choice. See our other answer choices are all incorrect. We could rule them out right away because none of them had me aosis first. See you in the next video
