The processes leading up to the birth of a newborn baby can be divided into several stages. review the stages listed in the prompt. order them, starting immediately after fertilization. a) embryo - fetus - infant - zygote b) zygote - fetus - embryo - infant c) zygote - embryo - fetus - infant d) embryo - fetus - infant - zygote

The correct answer is -

C) zygote - embryo - fetus - infant.

In placental mammals (such as human beings), the haploid sex cell (gametes, such as sperm and egg) produced by each parent are fused to produce diploid zygote, which undergoes multiple rounds of cell division (mitosis) and goes through different stages (such as embryo, which is from conception till 8th week of pregnancy).

Embryo is further developed into more advanced stage (that is fetus, which is considered from 8th week till birth of baby) when the cells are still undergoing proliferation and differentiation to form specialised organs.

New born baby upto two years of age is considered as infant.

Thus, option C) is the right answer.

you must remain stopped until the stop signal is retracted and the red lights are turned off. approaching traffic in the opposite roadway of a divided highway shall not be required to stop, even if the school bus has the stop-arm extended and the alternately flashing warning signal lamps on.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
