Tumor cells are cells that divide relentlessly, forming solid tumors or flooding the blood with abnormal cells.
Answer:
0.1m/s
Explanation:
The speed, which refers to how fast an object moves within a period of time, can be calculated as follows:
Speed (m/s) = distance (m)/time (s)
Based on the provided information in the question, distance = 10m, time = 100s
Hence, the speed will be:
Speed = 10/100
Speed = 0.1m/s
Designing efficacious norovirus vaccines remains a major challenge due to several factors:
(1) the extreme genetic variability within the norovirus family and within genogroups
(2) the rapid evolution of antigenically dissimilar pandemic GII.4 norovirus strains
(3) the lack of lasting immunity upon natural exposure to noroviruses in at least a proportion of the population.
