During the course of successful prenatal development, a human organism begins as a a. embryo and finally develops into a zygote b. zygote and finally develops into an embryo c. embryo and finally develops into a fetus d. zygote and finally develops into a fetus e. fetus at finally develops into an embryo d. zygote and finally develops into a fetus

The correct answer is D. zygote and finally develops into a fetus

Explanation:

Zygote is formed by the fusion of male gametes and female gametes. It is considered as the first stage of development of a baby. Zygote is a unicellular structure which develops into an embryo which is a multicellular structure.

Then this embryo develops and is called a fetus at the starting of the 11th week of pregnancy. A developed fetus is the final stage of prenatal development.

Therefore during successful prenatal development, a human baby begins as a zygote and finally develops into a fetus. So the correct answer is D.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
