Answer: allele, gene, DNA, chromosome, nucleus
Explanation: An allele is a variant of a gene or a different form of a gene. A gene is a segment of a DNA that codes for an RNA or a protein. A DNA is a genetic material that contains all the genetic information of an organism. A DNA is packaged and condensed into a threadlike material known as chromosome and chromosomes are found in the nucleus of a cell.
Answer:
Classification system changes because the scientists find new evidence in their studies.
Explanation: The world is always changing and growing and dying as well as developing, so over time things change. For example, as you grow up do you stay the same? No, you notice the physical changes happening, well thats sort of like how the earth and its ways are always changing as well.
We examined the biogeographic patterns implied by early hominid phylogenies and compared them to the known dispersal patterns of Plio-Pleistocene African mammals. All recent published phylogenies require between four and seven hominid dispersal events between southern Africa, eastern Africa, and the Malawi Rift, a greater number of dispersals than has previously been supposed. Most hominid species dispersed at the same time and in the same direction as other African mammals. However, depending on the ages of critical hominid specimens, many phylogenies identify at least one hominid species that dispersed in the direction opposite that of contemporaneous mammals. This suggests that those hominids may have possessed adaptations that allowed them to depart from continental patterns of mammalian dispersal.

Answer:
Myelodysplastic (Ans. A)
Explanation:
Acute myeloblastic leukemia (AML): Is also called malignant blood cell cancer which can affect both adults & children. It is a fast-growing malignant disease where too many immature myeloblasts (WBS) are found in the RBC & bone marrow. Acute myeloblastic leukemia starts while chronic leukemia present from a long time & grow gradually. Symptoms of acute myeloblastic leukemia are:
High fever, a large no. of infections over a short period, pain in the joints, sweating a lot, etc.
Myelodysplastic syndrome: It is a group of disorder caused by blood cells (which is immature & don't work properly). Instead of developing properly the blood cells die in the bone marrow. After sometimes there are more immature cells than healthy ones, causing the problems infection caused by leukopenia, etc.
