Textbook Question
Chapter 22, Problem 10TYU
FOCUS ON INFORMATION
In sexually reproducing species, each individual begins life with DNA inherited from both parent organisms. In a short essay (100-150 words), apply this idea to what occurs when organisms of two species that have homologous chromosomes mate and produce (F1) hybrid offspring. What percentage of the DNA in the F1 hybrids' chromosomes comes from each parent species? As the hybrids mate and produce F2 and later-generation hybrid offspring, describe how recombination and natural selection may affect whether the DNA in hybrid chromosomes is derived from one parent species or the other.

What would be the protein needs of a man named Josh who exercises moderately and is the same age and size as Wayne? Josh is 5 ft, 8 in tall and weighs 183 lb. Round the number of grams to the nearest whole number. During calculations, use numbers rounded to the first decimal place. Because protein requirement is a range, please enter two numbers: lower and upper range values, respectively.

Current treatments are focused on highlyactive antiretroviral therapy (HAART). HAART usually consists of an orally delivered drug cocktail containingtwo different reverse transcriptase inhibitors and one other drug, such as a protease inhibitor. Question: Develop a pharmacokinetic model of HAART treatment. Consider all 3 drugs. Make sure to include adiagram that illustrates your thinking, state all assumptions, and define your variables.

Marine fish cells are hypotonic compared to their seawater environment; their cells lose water by osmosis and gain solutes.
