Below is a list of physiological events involved in modulating respiratory rate. Using your knowledge from class, place the events in the correct order. A. Medullary respiratory centers are stimulated.
B. CO2 levels in blood decline.
C. Somatic motor impulses are sent to the respiratory muscles.
D. Diaphragm and external intercostals contract at a faster rate.
E. More CO2 is exhaled.
F. Extracellular fluid surrounding brain decreases in pH.
G. PCO2 increases in blood H. CO2 produces H by reacting with water.
I. Central chemoreceptors are stimulated.
J. pH of brain extracellular fluid returns to normal.

The process by which natural forces move weathered rock and soil brim one place to another is called

Chapter 11.1 & 11.2 notes section 11.1 1. every living thing has a set of ? inherited from its parents. 2. after becoming a ? , mendel spent several years studying ? and mathematics at the university of vienna. 3. during sexual reproduction, male and female reproductive cells join, a process known as ? . 4. pea flowers are normally ? , which means that sperm cells in pollen fertilize the egg cells in the ? flowers. 5. when mendel crossed plants with ? characters for the same trait, the resulting offspring had only one of the characters. 6. a ? is a specific characteristic, such as seed color or plant height, that varies from one individual to another. 7. filius and filia are the latin words for ? and ? . 8. the offspring of crosses between parents with different traits are called ? . 9.to mendel's surprise, all of the offspring had the character of only ? of the parents. 10. mendel's first conclusion was that biological inheritance is determined by ? that are ? from one generation to the next. 11. scientist calls the chemical factors that determine traits ? . 12. mendel's second conclusion is the ? . 13. the principle of dominance states that some alleles are ? and others are ? . 14. when mendel allowed the f1 plants to reproduce by self-pollination the traits controlled by ? alleles reappeared in about ? of the f2 plants in each cross.

Next pretest: evolution select the correct answer in a laboratory population of flies, the female flies are gray and the males are yellowish gray. biologists observed that all the male flies had an equal chance for reproduction, but the male flies with the brightest colors were more likely to successfully reproduce. what phenomenon could explain such a change? a sexual selection b. disruptive selection c. stabilizing selection d. directional selection
