Answer:
Mitosis creates diploid cells, while gametes (sperm and oocytes) are haploid cells
Explanation:
Mitosis is the process by which somatic (non-germ line) cells replicate, and two identical cells, called daughter cells are produced from each division. These cells are diploid, meaning that the cell has paired chromosomes. Meiosis is the process by which gametes, sperm cells and oocytes, are produced and these cells must be haploid, or contain unpaired chromosomes, so that when fertilization occurs, the chromosomes from the sperm cells and the chromosomes from the oocytes can recombine to create unique pairs of chromosomes for the resulting zygote. Thus, mitosis will never be able to create germ cells as germ cells must be haploid.
Theory relates to a model in science because it presents the possible paradigms and patterns of the said concept and fact. It explains and elaborates the phenomenon of why it happened, how it happened and the factors that are involved in the process. A theory is a possible explanation of certain occurrence.
In addition, any time a scientific theory is challenged, it means it's not a good theory. And this statement is not valid. In theoretical models, they are revisited when there are further studies and discoveries found in a certain area where they can be remodeled and reintegrated instead of disregarding its credibility. Models, theories, and paradigms are not challenged but rather encouraged, they are supported in many studies since these theories and models were created in order for us to understand a certain phenomenon but it would likely help the scientific society to be updated in the new forms or spheres of improvement rather than discouragement. <span> </span>

D. descriptive investigations
Explanation:
A scientist studying the star Alpha Centauri would probably rely on descriptive investigation to gather data.
In descriptive investigation, experiments cannot be performed since the subjects cannot easily be manipulated or they are far too inaccessible. This form of investigation is based on indirect qualitative investigation of a phenomenon.
- Alpha Centauri is a distant star several light years away from the vicinity of the scientist.
- The best way to investigate this distance body is to make inferences from the evidence gathered from observatory stations using telescopes.
- Astronomers can collect different information and give vivid description of the distant start.
- It is highly impossible to make comparisons and alter variable in this kind of investigation.
