For any of the questions below, do not do math. If there are component chances, include them individually along with arithematic operators, e.g., 2/3 x 1/2. What is IV-5's chance of being a carrier? What is V-3's chance of being a carrier? If two carriers mate, what is the child's chance of being homozygous recessive? If IV-5 and V-3 were to have a child together, what is the chance the child would be affected? This pedigree shows the transmission of an autosom.

For a review session in preparation for an animal diversity exam, you asked each of the attendees to submit a statement concerning animals and the characteristics that define them as a group. Which of the statements below is most likely to classify a creature specifically as an animal and to exclude non-animals from inclusion in the group? Animal development requires the use of collagen genes but not Hox genes. Additionally, specific rRNA molecules, similar among all animals, are required. Animals do not have unique rRNA or developmental genes. The unique features of animals center on their use of a nervous system for movement and reproduction. Animals require the use of Hox genes during development, have collagen genes, and have specific rRNA molecules that are similar among all animals. Animals can produce their own food and their cells contain cell junctions. Additionally, they contain specific rRNA molecules, similar among all animals..

For 100 births, P (exactly 57 girls )=0.0301 and P(57 or more girls )=0.097. Is 57 girls in 100 births a significantly high number of girls? Which probability is relevant to answering that question? Consider a number of girls to be significantly high if the appropriate probability is 0.05 or less. The relevant probability is so 57 girls in 100 births a significantly high number of girls because the relevant probability is 0.05.

Following the Crash of 1929, the stock market: Multiple Choice A) began to slowly, but steadily, increase in value. B) was flat for about three years and then began a slow, steady rise to pre-crash values. C) continued to decline slightly before increasing over a 3-year period to its pre-crash values. D) temporarily increased in value and then began a 3-year decline to ten percent of its pre-crash value. E) recouped its 90 percent loss.

Following Gali and Monacelli (2005) who utilize a utility function that characterizes additively separable preferences, suppose a representative household maximization problem is characterized as follows: maxt,Nt,Dt+1}t=0Ett=0t[1Ct11+Nt1+]s.t.PtCt+Et{Qt,t+1Dt+1}Dt+WtNt+Tt. and also noting the following: PH,tCH,t+PF,tCF,t=PtCt where [0,1] is a discount factor, Ct is aggregate consumption and Nt is labour hours. The household spends/consumes domestic (CH,t) and imported goods (CF,t) with prices PH,t and PF,t respectively and PH,tCH,t+ PF,tCF,t=PtCt, where Pt is the aggregate price and Ct is aggregate consumption. Household resources consist of a nominal wage derived from labour income Wt and lump-sum transfers Tt over period t. a portfolio of bonds Dt+1 is a nominal pay-off in period t+1 of a portfolio held at the end of period t (and which includes shares in firms). The stochastic discount factor for one period ahead nominal payoffs relevant to the domestic household is Qt,t+1. a) Formulate the Lagrangian of this representative household optimization problem. b) Determine the optimality conditions for this household problem c) Based on the optimality conditions, determine the consumption euler equation. Also specify your consumption euler equation to exhibit Rt=EtQt,t+11 which is the gross return on a riskless one period discount bond paying off one unit of domestic currency in t+1 with EtQt,t+1 being its price..

Folds Anticlines and synclines - Now that you undertand simple inclinel planes, Plunging folds- Younger layers of which simulate limbs of folds, let's tackle folds in their entirety. Figure 14.5 rock overlie older layers of rock (like shows two bacic types of folds an anticline (arch-shaped) and a syncline (trough-. layers in a cake). In the structural shaped). Both are shown in block diagram (lefi) and in map view (right). examples presented thos far it has been obvious which rock layers overlie which. However, not all fold axes are horizontal. Some folds are tilted so that their axes are said to plunge (i.e., slope downward as in Figure 14-6), You might say that these structures "dip." (Imagine in Figure 14-6A that you are tipping a hog trough and spilling its contents in the direction of plange.) In such cases the relative ages of rock layers are less obvious. Hint As a guide to which of two contigueus layers is older, just look to see which overlies which along any vertical line on any sile of the block diagram. Figure 14-5 A. An anticlitie, B. A syocline. (Map vicws so the right) A fold axis runs along the crest of a fold and bisects it into two limbs. A fold axis ean be considered here as synonymous with the term hingeline, which runs along the line of maximam curvature of a fold. (Hingeline is: analogous to the pin in a door hinge. with the plates of the hinge simulating the limbs of the fold.) Figure 14-6. Planging folds. A. A fold: plunging toward you. Note the inclined axis (arrow) R. A fold plunging away from you. The map patteras for the two are ilbe saine, but the armangeminens of layen differ. Q14-5. In Figure 14-6/, what basic type of fold is illustrated (Le. anticline or syncline)? Which layer is the oldest (a,b, c,d, or e)? Q14-6. In Figure 14-68, what basic. type of fold is ifiustrated (i.e, anticline or syncline)? Which layer is the oldest (a, b,c,d, or e)?.
