Please find the diagram attached and explanation below.
Explanation:
Mitosis is a type of cell division that forms two genetically identical cells. It involves four stages viz; prophase, metaphase, anaphase, and telophase.
Considering a diploid (2n) cell with four (4) number of chromosomes.
Prophase- four duplicated chromosomes condense and pair up.
Metaphase- four chromosomes line up at the cell plate or equator in order to get separated.
Anaphase- the sister chromatids are pulled apart by the spindle microtubules
Telophase: the chromosomes recoil and organelles form at opposite poles of the cell.
At the end of cytokinesis, which is division of the cytoplasm, four chromatids are present in each daughter cell. The chromatids becomes individual chromosomes that retain the diploid (2n) chromosome number of four.
Answer:
A) 0.83 for lung cancer and 0.18 for coronary thrombosis.
Explanation:
For the population etiologic fraction due to smoking, we use the formula:
For lung cancer:
Given:
We first find RRs which is the relative risk of dying from cancer for a smoker compared to a non smoker.
= 10.1429
Therefore population etiologic fraction due to cancer wil be:
= 0.8341
Population etiologic fraction of cancer due to smoking is 0.834
•For coronary thrombosis:
Let's use the formula:
Let's first find the RRs (relative risk of dying from cornary thrombosis for a smoker compared to a non smoker)
The population etiologic fraction of cornary thrombosis due to smoking, will be:
= 0.187
The population etiologic fraction of cornary thrombosis due to smoking is 0.187
Therefore the answer is option (A) 0.83 for lung cancer and 0.18 for coronary thrombosis
