b. 4 They assumed that different ways of separating an embryo into two parts would be equivalent as far as the fate of the two parts was concerned.
c. 4 I and III only
Explanation:
The passage demonstrates the importance of two factors in the development of an embryo: cleavage planes of division of embryonic cells and cell differentiation.
Cleavage Planes:
Cleavage basically refers to the division of the zygote into a large number of cells called blastomeres. Cleavage planes are geometrical lines or orientations along which cleavage takes place. Since, all embryonic cells are the precursors of some type of body cells, the cleavage planes determine if the cells are adequate for growth and development.
Cell Differentiation:
Cell differentiation is the transition of an undifferentiated cell into a specialized one. For example, stem cells are undifferentiated cells that develop into progenitor cells that mature into a specific cell lineage. For an embryo to regenerate, the presence of adequate embryonic stem cells is crucial. Embryonic stem cells are present in abundance before the gastrulation phase of embryonic development, after which they rapidly start differentiating.
A sexual is reproduction without a partner sexual reproduction is reproduction that involves 2 partners
Answer:
More educated or cognitively able participants thought scientific disputes were more often due to the topic's irreducible complexity/uncertainty and to expert bias (e.g., personal values or external social forces influencing scientific claims), while the less educated or cognitively able favored scientists.

Answer:
The common element in RNA interference treatment for aids,hepatitis,and cancer include the silencing of gene expression.
Explanation:
- Through the degradation of targeted mRNA, gene silencing is done which is very popular in the eukaryotic organism and it is a highly conserved process.
- In the treatment of aids,hepatitis,and cancer, gene therapy is needed because they cannot be cured by simple consumption of drugs.
- The treatment is carried by silencing the gene expression of the particular mRNA host by utilization of RNA interference (RNAi).
