B. Solar activity
C. Earth's tilt
D. Volcanic activity
A) Mitochondria
B) Golgi bodies
C) Nucleus
The correct option is A.
Mitochondria is one of the organelles that are found in living cells and it is the one responsible for the production of ATP, which is the source of energy that is usable by the cells. Mitochondria is designed in such a way that, it will be able to carry out its functions efficiently. Mitochondrial has two membranes, one at the outside and the other one at the inside. While the outer membrane is smooth, the inner one is highly folded and it formed a structure called cristae. The folding of the inner membrane serves to increase the surface area inside the mitochondria.
B.Lipids
C.proteins
D.Nucleic Acids
Nucleic acids are the carbon compounds that store and transmit hereditary information. Primarily DNA and RNA, they serve as the molecular 'blueprints' for the formation of proteins necessary for cellular structure and function.
Among the listed compounds: Carbohydrates, Lipids, Proteins, and Nucleic Acids; it is the nucleic acids that store and transmit hereditary information. Nucleic acids, such as DNA and RNA, are complex compounds that serve as the blueprints of life.
DNA (Deoxyribonucleic Acid), in particular, contains the molecular instructions for the proteins that our cells need for structure and function. RNA (Ribonucleic Acid), on the other hand, helps in transmitting these instructions from DNA to the protein-building machinery of the cell.

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.
