Multiple Choice

Assume that a researcher randomly selects 14 newborn babies and counts the number of girls selected, x. The probabilities
corresponding to the 14 possible values of x are summarized in the given table. Answer the question using the table. $$\begin{array}{l}\text { Probabilities of Girls }\\\begin{array} { | c | c | c | c | c | c | } \hline x \text { (girls) } & P ( x ) & x \text { (girls) } & P ( x ) & x \text { (girls) } & P ( x ) \\\hline 0 & 0.000 & 5 & 0.122 & 10 & 0.061 \\1 & 0.001 & 6 & 0.183 & 11 & 0.022 \\2 & 0.006 & 7 & 0.210 & 12 & 0.006 \\3 & 0.022 & 8 & 0.183 & 13 & 0.001 \\4 & 0.061 & 9 & 0.122 & 14 & 0.000 \\\hline\end{array}\end{array}$$

Selective Gene Expression

This describes the process by which certain genes are activated to produce a specific set of proteins in different cell types, conditions, or stages of development.

Cell Differentiation

The process by which a less specialized cell becomes a more specialized cell type, crucial in development and specialization of functions.

Embryo

In animals, a developing individual from first cleavage until hatching or birth; in humans, usually refers to an individual during weeks 2 to 8 of development.
