In pea plants, round (R) is dominant to wrinkled (r). A heterozygous female is crossed with a wrinkled male. Make a Punnett Square to determine the possible offspring.

a. What are the possible genotypes of the offspring?

b. What are the possible phenotypes of the offspring?

c. What is the probability of having an offspring that is round?

d. What is the probability of having an offspring that is homozygous?

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
