I believe it would be "bones start to replace cartilage to form the beginnings of a skeleton" since that happens in months 7 and 8
Answer:
Ultraviolet (UV) photons harm the DNA molecules of living organisms in different ways. In one common damage event, adjacent bases bond with each other, instead of across the “ladder.” This makes a bulge, and the distorted DNA molecule does not function properly.
Explanation:
Answer:
Genetic engineering has its grass roots from the recombinant technology.
Explanation:
Genetic engineering is seen to have started from a scientists activity which involved restriction enzymes and DNA ligases that were used by Paul Berg in 1972 to create the first recombinant DNA molecules. A monkey virus which is SV40 was combined with a lambda one. Following that, the results of the experiment and attempts were further investigated by other scientists and later, the first plant that underwent genetic engineering was the plant tobacco.
Taxonomy s the branch of science that deals with the classification of living and extinct organisms.
Using taxonomy, plants and animals are classified according to the following: Domain, Kingdom, Phylum, Class, Order, Family, Genus and Species. Taxonomy is also used to identify the species that are related to each other.
Organisms are named using the binomial system of nomenclature that was developed by Linnaeus. The binomial system, also known as the scientific name, is consist of two parts: the Genus name and the Specific Epithet.
For this problem set, the Mergus serrator and the Mergus merganser is closely related to each other, since they both have the same Genus.
