What else can I help you with?
Is the process of fertilization painful?
No, fertilization itself is a biological process that occurs within the reproductive system and is not painful. It involves the fusion of a sperm and an egg to form a zygote, which is the first stage of a developing embryo.
Which period of prenatal development is where the major organs are first developing?
The period of prenatal development where major organs start developing is called the embryonic period. This stage typically occurs from about week 4 to week 8 after fertilization. This is a critical period for organ development and any disruptions during this time can lead to significant birth defects.
Which pair or terms describes the usual location for fertilization and the first stages of development in human reproduction?
The usual location for fertilization and the first stages of development in human reproduction is the fallopian tube. After fertilization occurs in the ampulla of the fallopian tube, the resulting zygote undergoes initial cell divisions as it travels toward the uterus. This journey typically takes about 5-7 days, during which the embryo develops into a blastocyst before implantation in the uterine lining.
How many cells does a zygote have?
A zygote has one cell, which is formed when a sperm fertilizes an egg during fertilization. The zygote contains the genetic material from both the father and mother and is the first cell of a new organism.
What happens first mitotic cell division in a testis or the process of fertilization?
the cell changes
What is developing during the first trimester?
a baby
Is the process of fertilization painful?

Is your fetus a female during the first trimester of pregnancy?
Your fetus' sex is determined at fertilization. However, the external genitalia don't start developing until the 11th week of gestation, but will still not be visible on ultrasound.
When a egg and sperm combine what is it called?
The combining of an egg and sperm to create 1 single cell is "conception."
What is an embryo human?
An embryo is the early stage of human development, typically within the first eight weeks after fertilization. During this stage, the cells are rapidly dividing and differentiating to form the various tissues and organs of the body.
What is the developing baby called during the first trimester?
The embryonic period extends to the end of the eight week. After the embryonic period (8weeks), the developing human is called a fetus.
Which period of prenatal development is where the major organs are first developing?
The period of prenatal development where major organs start developing is called the embryonic period. This stage typically occurs from about week 4 to week 8 after fertilization. This is a critical period for organ development and any disruptions during this time can lead to significant birth defects.
What happens during first trimester?
The major organs systems have started developing.
What is first embryo or foetus?
An embryo forms first during pregnancy, after fertilization of the egg by sperm. It develops into a fetus around the end of the eighth week of pregnancy.
After the first eight weeks of pregnancy the developing offspring is called a(n) .?
After the first eight weeks of pregnancy, the developing offspring is called a fetus. This stage marks significant development as the major organs and systems begin to form and mature. The fetus continues to grow and develop until birth, typically around 40 weeks of gestation.
What is the first stage of fertilization?
embryo
What is formed first after fertilization?
zygote
