<span>The phospholipid bilayer has a fluid makeup, so this allows vesicles to go from one part of the cell to another and fuse with those areas. The vesicles then go into these areas and deposit the needed substances or pick up waste products from these areas in order to remove them from the cell.</span>
Answer:
The correct answer is b a mutation in a gene that codes for protein regulating cell division.
Explanation:
Cancer is a disease that result due unregulated cell divison.There are many tumor suppressor protein present in our body such as retinoblastoma tumor suppressor protein,p53 protein.
These tumor suppressor protein helps to carry out cell divison in a regulated fashion and send signal for division only to that cell that have undamaged DNA.
Mutation in the gene encoding tumor suppressor protein leads to development of cancer.
Answer:
of diffusion
Explanation:
Molecules move down a concentration gradient without the need to use energy. This means they move from a high concentration to a low concentration. This occurs across a semi-permeable membrane, like the cell membrane, by simple diffusion.
