The answer is C. What you are implying is that all the time it took for the zygote to develop to embryo (8-10) weeks or 2 months is not put into consideration. You sef read it to yourself again na "btw the formation of foetus and birth" it means you can as well say gestation period for man is 7 months because you are not putting into consideration the time of the development from fertilization to development of zygote and then embryo and finally foetus.
Please correct this thing ASAP
The correct and is C. Because it's period from conception (fertilization I.e zygote formation) to birth. Thanks
Gestation is the period of development of the embryo and fetus inside the mother's uterus in mammals, from fertilization (or zygote formation) to birth.
Analyzing the Options:
A) required for growth after birth:** This is **incorrect**. Gestation is the period *before* birth.
B) between the formation of the foetus and birth:** This is **correct** and is the most accurate definition of gestation.
C) of development from zygote to birth:** This is also **correct** and is essentially the same as option B, just slightly more specific.
D) before the formation of the zygote:** This is **incorrect**. Gestation begins *after* the zygote is formed.
Therefore, the correct answers are B and C. If you must choose one, C is the most comprehensive.**
The most appropriate answer is C) of development from zygote to birth.**
Myschool the answer is C
Gestation is the period of time between conception and birth. During this time, the baby grows and develops inside the mother's womb. ... It is measured in weeks, from the first day of the woman's last menstrual cycle to the current date. A normal pregnancy can range from 38 to 42 weeks.
Gestation in mammals is the period **of development from zygote to birth**. So, the correct answer is C. Of development from zygote to birth. This period varies between species and is the time in which a fetus develops, beginning with fertilization and ending at birth. For most species, the amount a fetus grows before birth determines the length of the gestation period..
Greetings, The Myschool Team.
The correct answer is C(of development from zygote to birth) and not B(between the formation of the foetus and birth). The period of gestation in biology is defined to cover the length of time from conception(union of the male and female gametes to form a zygote) to birth. It is not limited to cover only the timespan from foetus formation. Here are some sources and references in this regard:
"Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent)"
Source: Wikipedia
They also define an embryo as
"An embryo is the initial stage of development for a multicellular organism. In organisms that reproduce s*xually, embryonic development is the part of the life cycle that begins just after fertilization of the female egg cell by the male man-fluid cell. "
Also, from Encyclopedia Britannica:
"gestation, in mammals, the time between conception and birth, during which the embryo or fetus is developing in the uterus."
Thus, the correct and most appropriate answer is C(of development from zygote to birth) and not B(between the formation of the foetus and birth). Thank you.
For mammals the gestation period is the time
in which a fetus develops, beginning with
fertilization and ending at birth. [1] The
duration of this period varies between species.
