A. The onset of the menstrual flow
Answer:
The simulation only shows how a population can change overtime in response to the changes in the environment. During the industrial revolution, one particular phenotype of moths had an advantage over the other and hence, was subjected to natural selection. What this simulation does not tell us is the causality and correlation aspect of the change that occurs in the moths. Correlation does not equal causation, and the simulation does not shed any light on these variables in this case.
Explanation:
Hope that answers the question, have a great day!
Large central vacuoles, chloroplasts, and cell walls are only found in plant cells.
Large central vacuoles store nutrients and waste products, but they also maintain the plants' structures.
Cell walls also maintain structure and rigidity.
Chloroplasts are used in the process of photosynthesis, which only occurs in plants.
Answer:
Nucleus
Explanation:
Prokaryotes are the organism that came earlier than eukaryotes on this earth. These prokaryotes do not have a nucleus and other membrane-bound organelles like chloroplast, mitochondria, Golgi apparatus, endoplasmic reticulum, etc.
So as prokaryotes lack membrane-bound organelle their genetic material is not enclosed in the nucleus therefore their genetic material remains in the cytoplasm of the cell while eukaryotes have membrane-bound nucleus in which their genetic material are present.
So the nucleus is the major organelle that prokaryotes are missing that eukaryotes have.
