Answer: Large molecules and wastes move through the membrane through forms of active transport- endocytosis and exocytosis.
Explanation:
Molecules are moved across the cell membrane via different mechanisms like diffusion, facilitated diffusion and passive transport; however, some very large molecules require specialized types of active transport to cross over- these are endocytosis and exocytosis.
During endocytosis large molecules cells and cell fragments moved across the plasma membrane through a process of <em>invagination;</em> piece of the external cell membrane falls into itself and forms a small pocket that surrounds the target molecule this breaks off from the membrane to form an intracellular vesicle. Different methods of endocytosis such as <em>phagocytosis, pinocytosis </em>and receptor-mediated <em>endocytosis</em>, take in cells, water and targeted substances respectively.
Like endocytosis, the particles (signal proteins, neurotransmitters and waste material) are surrounded by a phospholipid membrane. However, in exocytosis, this membrane is formed in the cytoplasm, and merges with the plasma membrane’s interior in a process <em>opposite to </em>endocytosis; material is removed from the cell and exported into the cell’s exterior called the extracellular space.
The answer to this question would be: <span>lung cancer
In 1950, the medical practitioner doesn't know the relation of cigarette smoking with lung cancer. In that era smoking advertising is very massive and some physician even helps it. This cause increased amount of lung cancer incidence. The amount of lung cancer continues to increase till 1980-1990</span>

Explanation:
A characteristic of the primates, when they evolved was the replacement of the claws by ones, the binocular vision, which generated these two characteristics the option to see and take better the insects and fruit in high branches
