The drug colchicine inhibits the formation of spindle fibers during mitosis. If you treat dividing plant cells with colchicine,
vekshin1

Answer:

D

Explanation:

During metaphase of cell division, the chromosomes line up in the metaphase plate and the spindle fibers from the poles extend and attach to the centromeres of the chromosomes. The spindle then contracts and pull different chromosomes to the opposite poles of the cell before the parent cell divides.   If spindle fibers do not form, then the chromosomes will not separate during anaphase.

Therefore, the final cell after mitosis will be a cell with double the number of chromosomes -because if you remember, during interphase, genetic material is replicated so each daughter cell can have its copy-. Due to quality control in the process of cell divisison, this cell will mostly undergo apoptosis, otherwise, it could develop into cancer.

Scientists had suspected that our planet formed dry, with high-energy impacts creating a molten surface on the infant Earth.

Answer: 4.6 billion years.
