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.

The study of comparative anatomy predates the modern study of evolution. Early evolutionary scientists like Buffon and Lamarck<span> used comparative anatomy to determine relationships between species. Organisms with similar structures, they argued, must have acquired these traits from a common ancestor. Today, comparative anatomy can serve as the first line of reasoning in determining the relatedness of species. However, there are many hidden dangers that make it necessary to support evidence from comparative anatomy with evidence from other fields of study.</span>
Answer:
It could largely impact the way you look.
Explanation:
Since 100% of your DNA decides how you look, if even one thing changes, one part of your look would change. Sometimes it's something big like eye color, or sometimes like a small change in skin color.
The statement “This type of evidence can be checked by others” best explains the importance of empirical evidence in science.
Explanation:
There are all kinds of evidence used in science, but empirical evidence is obtained as a result of <u>repeated experiments and observations</u>. This evidence is used to either support or argue against a scientific theory. Empirical evidence is the preferred evidence since this kind of evidence can be peer reviewed, i.e. reviewed by other scientists and/or researchers. In other words, the experiment can be redone, and the <u>evidence can be tested</u>.
Answer:
Membrane proteins perform a variety of functions vital to the survival of organisms: Membrane receptor proteins relay signals between the cell's internal and external environments. Transport proteins move molecules and ions across the membrane.
Explanation:
they help transport some substances through the membrane.
