Process of Epitoky
The
gets rid of cell waste by breaking down large molecules into smaller ones for the cell to excrete. The
helps these waste molecules exit the cell.
Fat cells have three adaptive characteristics to allow the storage of fat. Describe the three characteristics.
An adult male is being discharged from the hospital following a myocardial infarction. The nurse knows that he understands the guidelines for resuming sexual activity if he states that
A. Bedtime is the best time to have intercourse
B. He should exercise for 10-15 minutes before intercourse to "warm up"
C. He should take nitroglycerin before intercourse to prevent chest pain
D.It is best to avoid having intercourse when the stomach is empty
You sample a large population of wild pea plants, and after counting 5000 individuals you find that 12% of them have white flowers (remember Mendel’s experiments, white is recessive to purple, single locus, 2 alleles). A) What are the frequencies of p (recessive allele) and P (dominant allele), assuming Hardy-Weinberg? B) Assuming 1 generation per year, and no selection, no migration, and random crossing between individuals (bees don’t care what color the flowers are), what will be the gene frequency in 3 years?
4. You are advising prospective parents on possible outcomes if they have children. Both are carriers of the gene for cystic fibrosis. If they have 2 children, what are the probabilities that a) one will have the disease? b) both will have the disease? C) both will be disease free but both will be carriers? d) both will be disease free, and neither will be a carrier?
In a small southern Italian village, there is a high frequency allele in the village population. This allele is a mutant variant of the normal hemoglobin gene, and the allele has a deletion of a large section of a big exon in the alpha chain hemoglobin gene—the resulting protein is missing 27 amino acids compared to the normal hemoglobin protein. Suggest 2 methods by which we might detect heterozygote carriers of this allele, and explain your logic. Hint—pedigree analysis is NOT one of these methods.
