Answer:
Explanation:
Based on the information provided, we can set up a 2x2 table to summarize the data as follows:
| Brain Tumor | No Brain Tumor | Total
--------------------------------------------------------
Exposed to Airflyte | 308 | 185 | 493
--------------------------------------------------------
Not Exposed | 77 | 430 | 507
--------------------------------------------------------
Total | 385 | 615 | 1000
In this table, the rows represent the exposure status (exposed to Airflyte or not exposed), and the columns represent the occurrence of brain tumors (brain tumor or no brain tumor). The totals are calculated for each category.
Please note that the numbers provided in the table are based on the given data and do not reflect any statistical analysis or conclusions about the relationship between exposure to Airflyte and the development of brain tumors. Further statistical analysis, such as calculating risk ratios or conducting hypothesis tests, would be necessary to determine the strength of the association between the exposure and outcome variables.
A 2x2 table is set up to represent the brain tumor occurrence and non-occurrence in workers who were and were not exposed to the occupational toxin Airflyte. There were 308 cases of tumors in the exposed group and 77 in the non-exposed group. The rest did not develop tumors.
In conducting this study, the researchers divided the 1,000 men into two groups: those exposed to the occupational toxin Airflyte and those not exposed. By using a 2x2 table, we can clearly illustrate the results obtained after the 10-year follow up. Here's how it looks:
With Brain Tumor Without Brain Tumor
Exposure to Airflyte
308 493 - 308 = 185
No Exposure to Airflyte
77 507 - 77 = 430
This table helps to visualise the observed differences in brain tumor development among the workers who were exposed to the toxin compared to those who weren't exposed.

Answer:
C. Placental mammals
Explanation:
The placentals are the largest group of mammals, totally dominating the class and terrestrial habitats.
Amnium, the fluid that protects the embryo from adhesions and shocks, is installed in the female's uterus for development with the help of a placenta that provides fixation and nutrients.
This breeding method, although producing a smaller number of offspring per pregnancy, has a high success rate, allowing greater chances of survival to offspring.
