18=4
I'm not that sure about 17, but I think it's right
<span>That statement is true
Abiotic factors (such as weather and environment) will determine which organism will be superior compared to another.
For example, Lion will be placed as the highest in the food chain if they're in Savanna environment. But, if we place that lion in the middle of the ocean, the lion will not has the superiority that it has on land.</span><span />
The effect Colchicine might have on dividing cells is that the duplicated chromosomes might not be able to segregate into daughter nuclei.
Colchicine is an alkaloid that attaches to tubulin and prevents it from polymerization to microtubules. As we know that Microtubules are a component of the cytoskeleton of a cell that aids in molecular mobility inside the cell.
During cell division, chromatin condenses into chromosomes, which are then connected to microtubules. The chromosomes are separated into daughter cells by microtubules.
When these cells are treated with colchicine, tubulin polymerization to microtubules may not occur, and the chromosomes containing daughter nucleic might not be separated.
