spindle-fiber structure because this is used to divide cells; cancer is just cells dividing way too much. so if the <em>spindle-fiber structure </em>were to fail it could cause cancer.
Answer:
D
Explanation:
Intestinal cell takes in glucose against Concentration gradient (uses energy in the form of ATP) to transport glucose into cell.
In blood cell, uptake of glucose occurs down concentration gradient. Hence, its facilitated diffusion (passive transport)
Glucose is a polar molecules due to presence of polar hydrophilic - OH group, hence carrier proteins are needed to provide a hydrophilic channel for glucose to enter the cell via facilitated diffusion.
Hey there!
The skin and nervous tissues develop from the ectoderm.
The cells show characteristics of tumors.
Tumor cells have the ability to grow and proliferate in absence of adhesion or anchoring. This is particularly helpful during metastasis when a cancer cell travels through the bloodstream to another location.

A cancerous cell has a number of mutations that regulate cell division. In addition, they exhibit impairment in DNA repair system. Therefore, cancer cell divided fast. Since the DNA repair system is nonfictional, the cells do not pause division to repair the mutation.</span>

b
Explanation:
its an organism consisting of cells in the form of chromosomes with a distinct nucleus.
