PLEASE HELP WILL MARK BRAINLIEST- Bacteria cells in your small intestine can receive signals from somatic cells, indicating a particular type of food has been ingested and to expect it in the intestines soon. What is the most valid hypothesis you can construct from this information?
a- Bacterial and eukaryotic cells must be able to undergo transduction with one another, so transduction may be an evolutionarily-conserved trait in both.
b- Bacteria and eukaryotes have evolutionarily-conserved similar enough mechanisms to be able to communicate.
c- The bacterial cells evolved many of the same organelles in their extranuclear cytoplasm that eukaryotic cells contain, showing evolutionary similarity.
d- The somatic cells must be emitting a hormone to communicate with the bacterial cells that have hormone recognition as an evolutionarily-conserved trait.

In german cockroaches, curved wing (cv) is recessive to normal wing (cv+). bill, who is raising cockroaches in his dorm room, finds that the frequency of the gene for curved wings in his cockroach population is 0.6. in his friend joe’s apartment, the frequency of the gene for curved wings is 0.2. one day joe visits bill in his dorm room, and several cockroaches jump out of joe’s hair and join the population in bill’s room. bill estimates that, now, 10% of the cockroaches in his dorm room are individual roaches that jumped out of joe’s hair. what is the new frequency of curved wings among cockroaches in bill’s room? 0.69 0.4 0.5 0.31 0.20
