Smoking is one of the major reason of Lung cancer. But one may have cancer even if the individual is not a smoker due to radiation, secondary air pollutants.
What is cancer?Cancer is described as the uncontrolled and abnormal growth of cells in one’s body which are arrested in the growth phase of the cell cycle and multiply rapidly and does not mature like normal cells, cancer is more aggressive form of a tumour.
The following describe the relation of smoking with lung cancer
Cancer is caused by oncogenes activating substances [OAS] some of them causes mutation in the bodyThese oncogenic substances in the smoke produced while smoking contains nicotine, hydrocarbons, cyclohydrocarbons and various other factors which converts normal cells into cancerous cells Hence, smoking causes oral and lung cancer

Answer:
this is my answer Key Takeaways. The nature versus nurture debate involves the extent to which particular aspects of behavior are a product of either inherited (i.e., genetic) or acquired (i.e., learned) influences.

A pair of membranes enclosing the nucleus with pores allowing the movement of molecules in and out of the nucleus is the nuclear.
Answers
Answer:
The nuclear membrane encloses the nucleus in eukaryotes. The membrane is penetrated by nuclear pore complexes.
Explanation:
The nuclear membrane (nuclear envelope, nucleolemma) isolates the interior of the nucleus from the cytoplasm. The membrane has two layers enclosing a distinct inner lumen (em). The nuclear membrane is penetrated by large nuclear pore complexes, which selectively transport molecules into or out of the nucleus. The luminal space within the double-layered nuclear membrane is continuous at points with the endoplasmic reticulum, a membrane-enclosed organelle (continuous with the outer nuclear membrane) to which are attached ribosomes (em2) executing translation of genetic coding into polypeptides and proteins.
Type V intermediate filaments are lamin proteins that have a nuclear signal sequence and form a filamentous support called the nuclear lamina just beneath the inner nuclear membrane. The lamina a net-like meshwork array that lines the inner nuclear membrane and governs the shape of the nucleus. Of the three nuclear lamin proteins, two are alternatively spliced products encoded by a single gene, while the third lamin is encoded by a separate gene. Nuclear lamins form a fibrous network that supports the nuclear membrane.
Lamins have a very long rod domain and carry a nuclear transport signal, they are located in the nucleus just beneath the nuclear envelope so they are vital to the re-assembly of the nuclear envelope after cell division. Lamins are phosphorylated at the end of prophase and this causes them to disassemble simultaneous with dissolution of the nuclear envelope. After cell division, they are dephosphorylated just before the nuclei of the daughter cells form and lamin filaments reassemble around each set of chromosomes. They are continuous except for a break at the sites of nuclear pore complexes. Lamins were probably the first intermediate filaments to evolve. Controlled by cdc2 kinase, lamin filaments disassemble prior to or early in mitosis then reassemble after cell division. Phosphorylation of serine residues in the N-terminal domain of lamin A by cdc2 kinase induces the disassembly of intact filaments and prevents reassembly.
Nuclear lamins help attach the chromosomes to the nuclear membrane and provide anchorage points for the nuclear pores. It is believed that nuclear lamins are the evolutionary ancestor of cytoplasmic intermediate filaments, which evolved through duplication and translocation of the gene product to the cytoplasm

Answers
Competition is the interaction of individuals that for a common resource that is in limited supply, but more generally can be defined as the direct or indirect interaction of organisms that leads to a change in fitness when the organisms share the same resource.
There are two major forms of competition. Two of them are interference competition and exploitation competition are categorized as real competition. Interference competition occurs directly between individuals, while exploitation competition and apparent competition occur indirectly between individuals.

Because it is a fluid system, the atmosphere is capable of supporting a wide spectrum of motions. These range from turbulent eddies of a few meters to circulations with dimensions of the Earth itself. By rearranging mass, air motion influences otheratmospheric components such as water vapor, ozone, and cloud, which figure prominently in radiative and chemical processes. Such influence makes the atmospheric circulation a key ingredient of the global energy budget.

Blood Vessels Blood flows through the circulatory system in blood vessels:Arteries are large vessels that carry blood away from the heart to the tissues of the body. Except for the pulmoNry arteries, all arteries carry oxygen-rich blood.Capillaries are the smallest vessels. Their thin walls allow oxygen and nutrients to pass from blood into tissues and wastes to move from tissues into blood.Veins return blood to the heart. Many have valves that prevent backflow. The contractions of the heart produce a wave of fluid pressure in the arteries, known as blood pressure. Without that pressure, blood would stop flowing through the body. The body regulates blood pressure through actions of the brain and the kidneys.
6. As blood flows through the body, it passes through three types of blood vessels. Complete the table by Nming each type and describing its structure and function.

Function
Answers
Answer:
Arteries = Transports blood away from the heart. They carry oxygenated blood away from the heart and to the body with the exception of the pulmonary artery that takes deoxygenated blood from the heart to the lungs to be oxygenated. They have large muscular walls to withstand the pressure of the heart beats and since there is such large pressure, they have smaller lumen compared to the veins as the pressure drives the blood forward.
Veins = Transports blood to the heart. They tend to carry deoxygenated blood to the heart except for the pulmonary vein. Large lumen and small muscular walls with valves. The large lumen is so that more blood can flow through the veins as there's less pressure which is also why there are smaller muscular walls. There are also valves in the veins to prevent the backflow of blood.
Capillaries = Allows gas exchange and waste diffusion into blood. It is also one cell thick to allow diffusion to happen efficiently and the small structure increases the surface area to volume ratio.
