This is a quiz related to Unit 9 - Growth and Development.


Questions and Answers
  • 1. 

    After ovulation, the ovum enters the abdominal cavity and then finds its way into the __________________________.

    Explanation
    After ovulation, the ovum is released from the ovary and enters the abdominal cavity. From there, it travels through the fallopian tubes, also known as the uterine tubes, towards the uterus. The uterine tubes provide a pathway for the ovum to reach the uterus, where it can potentially be fertilized by sperm.

    After about 3 days of constant cell division, a solid mass of cells, called _______________ is formed.

    Explanation
    After about 3 days of constant cell division, a solid mass of cells called a morula is formed. During the early stages of embryonic development, the fertilized egg undergoes multiple rounds of cell division, resulting in a cluster of cells known as a morula. The morula is a compact ball of cells that forms before the embryo implants into the uterine wall. It is the precursor to the blastocyst stage, where the cells further differentiate and organize into distinct cell layers. The formation of the morula is an essential step in early embryogenesis.

    By the time the developing embryo reaches the uterus, it is a hollow ball of cells called a _________________________.

    Explanation
    By the time the developing embryo reaches the uterus, it is a hollow ball of cells called a blastocyst. A blastocyst is formed after the fertilized egg undergoes multiple cell divisions and differentiates into two distinct cell types: an outer layer of cells called the trophoblast, and an inner cell mass. The trophoblast will eventually develop into the placenta, while the inner cell mass will give rise to the fetus. The hollow structure of the blastocyst allows for implantation into the uterine lining, where further development can occur.

    The three primary germ layers are the endoderm, the _______________________, and the ____________________________. (separate the words with a comma)

    Explanation
    The three primary germ layers are the endoderm, the mesoderm, and the ectoderm. These germ layers are formed during embryonic development and give rise to different types of tissues and organs in the body. The endoderm develops into the innermost layer of organs such as the digestive system and lungs. The mesoderm develops into the middle layer, giving rise to structures like muscles, bones, and the circulatory system. The ectoderm develops into the outermost layer, giving rise to the skin, nervous system, and other structures.

    The development of variuos tissues into organs is called _____________________________.

    Explanation
    Organogenesis refers to the process of various tissues developing and organizing themselves into organs. It involves the differentiation and specialization of cells, as well as the formation of complex structures and systems within the body. This process is essential for the proper functioning of organs and the overall development of an organism.

    ________________________ twins result from the fertilization of two different ova by two different sperm.

    Explanation
    Fraternal twins result from the fertilization of two different ova by two different sperm. This means that two separate eggs are released by the mother and fertilized by two separate sperm from the father. As a result, fraternal twins are no more genetically similar than any other siblings. They can be of the same or different sexes and may or may not resemble each other physically. This is different from identical twins, which result from the fertilization of a single egg by a single sperm and are genetically identical.
