Type five sentences in Spanish about this scene. Use ONLY course vocabulary and tenses.  ANY use of non-course covered vocabulary or tenses will result in a zero for the entire essay question. If a symbol or accented letter is needed copy and paste into your submission:     á      é      í      ó      ú      ñ Á      É      Í      Ó      Ú     ¿    ¡  

Refer to the picture to fill in the blank with the correct demonstrative adjective (this, that, those over there, etc) based on the location of the object relative to yours.  So the first set of objects is close to you, the second set is further away, and the third is very far away. If a symbol or accented letter is needed copy and paste into your submission:     á      é      í      ó      ú      ñ Á      É      Í      Ó      Ú     ¿     ¡ Ella ve __ cuaderno. 

Answer both questions: 1) What is the direct object? 2) Is a personal a needed in the blank? If a symbol or accented letter is needed copy and paste into your submission:     á      é      í      ó      ú      ñ Á      É      Í      Ó      Ú     ¡     ¿   Ellos buscan __ un estudiante inteligente.

EXTRA CREDIT STRESS SCENARIOS – For each of the following graphs, explain WHAT IS HAPPENING to raise the glucocorticoids (cortisol) level of the animals.  Note that you must go beyond what is already stated, which may require that you speculate on the cause of the glucocorticoids rise.  (Worth 1 point each)   ELEPHANTS – Foley et al. (2001) collected fresh fecal samples from 16 female elephants (Loxodonta africana) in three different groups over 23 months at Tarangire National Park, Tanzania, and analyzed them for fecal progesterone and cortisol metabolites. Social and ecological measures (rainfall) were collected concurrently. They noted a decline in body condition during the dry season. Elephant diet changes seasonally from high-quality grass in the wet season to less nutritious and more sparsely distributed leaves and bark in the dry season, and which time competition for good forage also increases.  They also noted that most births occurred during the wet season (Fig. 1).         

All are adaptive effects of glucocorticoid release except ___.

Based on the data presented in the graphs above, which of the following statements is MOST likely to be true?

Hoatzins build simple platform nests on branches overhanging the water. The modal clutch size is two eggs and the incubation period lasts 32 days; usually only one chick survives. If not disturbed, hatchlings stay in the nest 14–20 days and then begin to climb into the surrounding foliage. As an adaptation to life in inundated forests, hoatzin chicks prior to fledging show an extraordinary escape behaviour when approached by a predator: they jump into the water and may dive 5–15 m in an attempt to escape. With the help of their wing claws they climb another tree, but do not return to their nest site. Instead, the adults normally find the young and feed them until fledging.  The authors concluded that wildlife observation in the rainforest is not as harmless as often thought.      Fig. 3. Stress-induced corticosterone secretion of hoatzin chicks from undisturbed and from tourist-exposed nests. Each point represents the mean ± SE for the concentration of plasma corticosterone and sampling time for (a) nestlings from undisturbed and tourist-exposed sites, respectively and (b) juveniles from undisturbed and tourist-exposed sites, respectively.
