Answer:
S phase
Explanation:
In the eukaryotic cell cycle, chromosome duplication occurs during the "S phase" (stage of DNA synthesis) and chromosome division occurs during the "M phase" (mitosis phase).
Comparing the fossils through the geologic time scale, starting with the Precambrian and going towards the Quaternary, we can see that the fossils of the animals and the plants have gradually been becoming more and more complex.
While in the Precambrian period the living organisms have been relatively simple, most of the animals being covered with exoskeletons, living in water, the diversification much smaller, and the plants still being very primitive, in the periods that follow there's great changes. The plants become bigger and more complex, developing new way of life, while the animals develop bone structures inside their bodies. The diversification explodes. The living organisms grow in size, develop special and unique features, live in pretty much every environment.
Answer:
Chritsy must remove option A i.e "Is a transition metal"
Explanation:
Sodium is not a transition metal. It is a group element. Transition metal have very high density and boiling temperature like chromium which is a transition metal. Sodium do not have high density and boiling temperature.
Hence the correct option to be removed is option A i.e "Is a transition metal"
Explanation:
2.004 * 1^11 is not in scientific notation as there is no power of 10 written. We note that 2.004 * 1^11 equals 2.004, which can be written as 2.004 * 10^0.
