Answer:
Rocks can be divided into three basic classifications: igneous, sedimentary, and metamorphic. The following tests are used by experts to classify rocks: Hardness Test Minerals are scaled in range from 1 to 10, with 1 being softest and 10 hardest. The method of determining hardness is the scratch test.
30. Egg and Sperm
31. Haploid
32. Zygote
33. Diploid
34. Organism/ Embryo
35. Crossing Over
36. Tetrad
37. Asexual, Sexual
38. Both
39. Body
40. Sex Cell/ Gamete
41. Pro Phase 1
41. Genetic variation amongst daughter cells (4 genetically unique daughter cells)
42. In Anaphase 1, homologous chromosomes separate to each side of the cell, and the centromere is intact while in Anaphase 2, the sister chromatids separate and the centromere splits into two which result in two separate chromatids.
Hope this helps and you get your grade up lol
Answer:
Addition polymerization is a polymerization process that produces addition polymers. Addition polymers is a polymer that is formed by connecting or addition of the monomer units by a carbon-carbon bond without the use of other chemicals or without co-generation of other products.
It is different then condensation polymerization that co-generates other products or used other reactant chemicals. Polyyethene and polypropene are the examples of addition polymers.
Universal genetic code relate to the hypotheses about the origin of life on Earth <span>beacause of the RNA world hypoygeses. If RNA could self replicate then it could be a predecessor to how cell pass on their genetic materia today.</span>
