A is correct. DNA replication is just a different way of saying Meiosis II.
Answer: The correct option is D.
All of the above.
Explanation:
This is because complex organisms developed from cyanobacteria and release of oxygen. Cyanobacteria is a blue green algae and first organism that photosynthesized. It uses carbondioxide and water in the presence of the chlorophyll present and light energy to produce carbohydrates and oxygen. The oxygen released into the atmosphere brought about respiration and development of ozone.
This great oxidation event changed the Earth and life on Earth too.
Answer:
a)From the collision of protoplanet and proto-earth
The isotopic homogeneity of this highly refractory element suggests that lunar material was derived from the proto-Earth mantle, an origin that could be explained by efficient impact ejection, by an exchange of material between the Earth’s magma ocean and the proto-lunar disk, or by fission from a rapidly rotating post-impact Earth.
However, it remains uncertain whether more refractory elements, such as titanium, show the same degree of isotope homogeneity as oxygen in the Earth–Moon system.
Scientists still believe the general idea of having an impact forming disk that coalesced into the Moon is probably right, but this paper shows that scientists still don’t fully understand exactly what the mechanisms were. There is a lot of exciting research still to be done in this field!

Answer:
True
Explanation:
Nadia's body mass index (BMI) is 30, which means that she is overweight. Being overweight before or during pregnancy is a risk factor that can cause gestational diabetes what can lead to an overweight baby or put at risk the life of it. These factors lead to C-sections deliveries due to the big size of the baby or due to complications. High blood pressure can lead to preeclampsia, this puts at risk the life of the baby and the mother, and it can lead to preterm delivery. Also, there is a high probability that the baby has health problems in the future. For the reasons mentioned above, it is important to keep a healthy weight before and during pregnancy.
Gradualism and punctuated balance are two ways a species can evolve. By just one or both of these, a species can evolve. Scientists believe that species with a shorter evolution mostly evolved through punctuated equilibrium, and those with a longer evolution mostly evolved through gradualism.
