First, it is necessary that this scientist decide on what point of the Cretaceous period he wants to study. Among several points he may want to study the evolution of microorganisms of that time, the life of a dinosaur species, or the evolution of dinosaurs, the flora that was established during this period, among others. This is the phase of the scientific method called Observation.
After that, he must enter the phase called "Elaboration of hypotheses" where he will raise questions about the point he decided to study. "How many flower species existed in that period?", "How many of these flowers can we observe today?" among others.
After that, he will enter the phase called "Experimentation", where he will establish a type of experiment and all the experimental factors and variables that will allow the hypotheses to be answered.
After the experiment he will collect the data that will be analyzed and that will give results that will answer the hypotheses previously established. This is the phase called "Analysis of the results".
At that moment, he will be able to reach the last phase of the scientific method, the phase called "conclusion", where he will show the conclusions that the experiment allowed to be established.
Answer:
The correct option would be B. The stem cells will divide through mitosis to create diploid stem cells.
Explanation:
Mitosis can be described as a process by which all cells of the body replicate. The cell undergoing mitosis results in two diploid daughter cells.
Bone stem cell is a therapy in which stem cells from a donor are inserted into a patient so that the patient can form healthy tissues.
The stem cells, when given to a patient, will divide just like the normal cells of the body through the process of mitosis. The results will be two daughter cells having diploid chromosomes.
The ability of carbon<span> atoms to form covalent bonds with other </span>carbon<span> atoms is the most unique of its </span>bonding properties<span>. This enables </span>carbon<span> to form long, continuous chains, branches and loops consisting of </span>carbon<span> and hydrogen in hydrocarbons and only </span>carbon<span> in </span>carbon<span> allotropes such as C60.</span>
Answer:
The prey are usually smaller than the predator so they don't have as much energy.
Explanation:
He reasoned that since parallax could not be observed for celestial objects near the sun, then the earth was stationary. This erroneous assumption was because at the time he had no way of knowing that celestial objects were so far away that their parallax angles were too small to detect.He reasoned that since parallax could not be observed for celestial objects near the sun, then the earth was stationary.
