Three assumptions made by lifespan develop mentalists are: (1) a focus on human development‚ (2) an understanding of stability in addition to growth and change and (3) the perception that development persists throughout our entire life 2. Stages of the life span such as adolescence and middle age are universal across cultures and stable across history. FALSE 3. The

The germinal stage consist of when conception is starts to 2 weeks which the zygote implants itself in the mother’s uterine lining. The embryonic stage begins after the second seek but begins through and out the 3rd through the last 8th week. This point the blastocyst
Premium DNA Gene Genetics
Reproduction Male sperm fuses with female egg. If tdf (a gene) is present‚ then the embryo develops testes and produces testosterone. Female Reproductive system • Female baby develops if tdf is not present. • Tdf – a gene located on Y chromosome; if girl‚ then two X chromosomes‚ hence no Tdf. • Female hormones: progesterone and estrogen ( both secreted by mother’s ovaries and placenta which allow female genetilia to develop. Parts of the female reproductive system:

humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus but a small amount of DNA can also be found in the mitochondria. 4) How long is the germinal stage? Explain what happens in this stage. The germinal stage lasts only about 2 weeks. Within just a few hours after conception‚ the single-celled zygote begins making a journey down the fallopian tube to the uterus where it will begin the process of cell division and growth

Human Fertilisation and Development Each day cute little babies are born into this world and being dazzled by their beauty we forget all about the long complicating process that took place which made it possible to have a baby. Therefore in my essay I am going to discuss the human reproductive cell‚ fertilisation and the development of a human life. Humans reproduce sexually‚ with both parents contributing half of the genetic makeup of their offspring via sex cells or gametes. Gametes produced

The process of prenatal development occurs in three main stages. The first two weeks after conception are known as the germinal stage; the third through the eighth week are known as the embryonic period; and the time from the ninth week until birth is known as the fetal period. The germinal stage begins with conception‚ when the sperm and egg cell unite in one of the two fallopian tubes. The fertilized egg‚ known as zygote then moves toward the uterus‚ a journey that can take up to a week to complete

Prenatal Development The elaborate details of life begin with a single cell that develops into a full term fetus within approximately 40 weeks‚ 280 days or 10 lunar months. The course of this pre-natal development is divided into three main periods: germinal‚ embryonic‚ and fetal. In order to have a healthy baby at the end of the term‚ there are a few factors which have to be kept in mind by the mother. 1. Maternal nutrition Fetus gets the nourishment from maternal blood stream through placenta
