Answer: b.Germinal, embryonic, fetal
Explanation:
The period from conception to birth generally includes the order that is germinal, embryonic and fatal.
Germinal period: It begins with the rapid cell division and differentiation of the blastocyst which is a cell mass acts as a precursor of new life. The germinal period last for 2 weeks.
Embryonic period: This period lasts for 8-10 weeks. In this period a process called as gastrulation occurs in which the three layers called as germ layers develop. The ectoderm is the outer layer, the mesoderm is the middle layer and the endoderm is the inner layer. Each germ layer differentiate into different structures.
Fetal period: It is the final stage of development of the fetus. It last for 10-40 weeks of pregnancy. It initiate from the embryonic period till the birth of the full term fetus. It involves the development and specializing of structures. Organ system of the fetus develops in this stage.

The answer is c because they’re more similar then a and b
Answer:
GAR and AICAR transformylase
Explanation:
Tetrahydrofolate is essential for purine and pyrimidine synthesis, its deficiency can lead to inhibition of nucleic acid such as DNA and RNA and protein synthesis, which are important for the growth and survival of both normal cells and cancer cells. N-10-formyltetrahydrofolate acts as a donor of carbon atoms to the actively growing bases. It contribution is mediated by the action of the Glycinamide Ribonucleotide (GAR) transformylase and the N-5-aminoimidazole-4-carboxamide ribonucleotide (AICAR) transformylase.
