Explanation :
Answer: B) Lungs Explanation: Emphysema is a condition that involves damage to the walls of the air sacs (alveoli) of the lung i.e, primarily causes shortness of breath due to over-inflation of the alveoli. First, emphysema causes holes to gradually form inside the lungs' air sacs, thereby weakening their internal structure and inhibiting the exchange of oxygen and carbon dioxide.

Answer : 2. "Neutron"
Explanation :
Answer: B) Neutron Explanation: In nuclear physics, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and releases a very large amount of energy. Thus, The Nuclear Fission is caused by the impact of Neutrons.

Answer : 4. "All the above"
Explanation :
Answer: D) All the above Explanation: Random mutations are the ultimate source of genetic variation. Mutations are likely to be rare and most mutations are neutral or deleterious, but in some instances, the new alleles can be favored by natural selection. Polyploidy is an example of chromosomal mutation. Mutations are changes in the DNA. A single mutation can have a large effect. 1) mutation - an alteration in DNA sequence, various types 2) intragenic recombination - results in entirely new associations of genes not present in either parental genome. Two forms of intragenic recombination: a) crossing overb) independent assortment3) reticulation – acquisition of genetic material from unrelated or relatively unrelated sources (e.g., hybrid species, horizontal gene transfer).
