You are working on a research project that involves a mutational analysis of the light harvesting complex Lhca1, which is an important light harvesting complex found in plants. Your labmate asks where this complex is located. You say it is in the.
A. outer chloroplast membrane B. inner chloroplast membrane C. thylakoid membrane D. stroma E. matrix Clarify Question What is the key concept addressed by the question? What type of thinking is required? Gather Content What do you already know about how light harvesting occurs in photo systems during photosynthesis? What other information is related to the question? Choose Answer Do you have all the information needed to provide an explanation? Reflect on Process Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
Up until 20-30 years ago, people with cystic fibrosis (CF) wouldn't live long enough to reproduce
CF is a homozygous recessive condition, leading researchers to think that over time the incidence of CF would decrease because the allele would be removed from the gene pool. The results actually indicate that the rate of CF is on the rise. Which of the following would explain those results? A. We are being subjected to more mutations as a population due to more pollution. B. The population is increasing, and more people mean more mutations. C. The heterozygous condition is being selected for, much like what we see with sickle cell trait. D. People are traveling more, so when members from different areas reproduce, more mutations will result.
The difference between latex agglutination and coagglutination is:
