Answer:
C. The Z ring forms after chromosome segregation
Explanation:
Nucleoid occlusion, NO, is a mechanism in which the nucleoid prevents the the division of the chromosome in the cell's cylindrical part before segregation of the chromosome around the middle of the cell
NO is achieved by not allowing the formation of Z ring formation close to the nucleoid, (before the chromosome is segregated) thereby aiding the specification of the septation location
Therefore, the Z ring is formed after the chromosome is segregated
The answer is B) interphase

Answer: e. 2.5 ml
Explanation:
According to the dilution law,
where,
= concentration of stock solution = 20X
= volume of stock solution = ?
= concentration of required solution= 1X
= volume of required solution= 50 ml
Thus 2.5 ml much of a 20X tricaine stock solution is needed to dilute in order to make your solution.
Answer:
The hippocampus is important in helping the brain to STORE NEW MEMORIES.
Explanation:
People with damage to their hippocampus have virtually no capability of storing verbal or declarative types of memory in long -term memories, that is, they are unable store types of information that are the basis of intelligence. This is often called ANTEROGRADE AMNESIA.
Hippocampi are important in the output pathway from the reward and punishment areas of the limbic system among other structures.
Sensory stimuli or thoughts that cause pain excite the limbic punishment centers while stimuli that cause pleasure, happiness excite to reward centers. Hippocampi especially have a part to play in the response of the brain in making decisions about which of the thoughts are important on the basis of reward or punishment to be good for storing as memories. So any lesion or damage to this area causes loss of memory of the recent happenings both in long and intermediate term.
