The serous membranes are: Peritoneum — the peritoneal cavity is found within the abdominal & pelvic body cavities. Connecting peritoneum forms: — mesentery — ligament. Pleura — two pleural cavities (separated by mediastinum) are found within the thoracic cavity.
The F factor straightly handover the donor chromosome in the cross. H takes roughly 90 minutes to transfer the chromosome. The big share of the F factor is last to be transmitted and the conjugation tube is very subtle so the probability for a thorough transfer is low. Consequently, when the bacterial strain attempts to inoculate an Hfr plasmid into an F- strain transversely the conjugation bridge through rolling circle replication, it is infrequently completed and typically breakdowns off before the F factor section is totally transferred.
Answer:
Answer is D. Because the dog and cat are behaviorally isolated from each other.
Explanation:,
Isolation can be explained as a situation whereby organisms that ca interbreed and produce offspring could not, due to some factors.
Behavioral isolation is an example of isolation, and can be explained as a situation whereby two organisms that can interbreed could not, because of the difference in their mating rituals or signal.
In this case, the mating rituals or signal of the dog is different from that of the cat, and thus, prevent interbreeding between them.
Note that, other forms or types of isolation are ecological isolation, temporal isolation and mechanical isolation.
Another name for behavioral isolation is ethological isolation.
