Answer:
1- Presence of phenotypic variation
2- some phenotypic variation due to genetic variation
3- the given trait has an impact on fitness
Explanation:
The evolutionary theory by natural selection proposed by Darwin in his publication “On the origin of species” (1859) is based on a series of assumptions that enable to understand the amazing biodiversity on the Earth. First, individuals are not identical among them, i.e., there exists variation in the traits among the members of a given population, species, etc. Second, phenotypic variation leads to differential survival and reproduction of the organisms that are best fitted to the environment (i.e., competence among the members of the population). Finally, phenotypic traits are passed from generation to generation (i.e., phenotypic variation is inheritable), thereby favoring offspring from parents more adapted to the environment.
Answer:
Explanation:
- cancerous cells continue to grow and divide
- there are a variation in the size of cancer cells
- the nucleus of a cancer cells is darker and larger than a non-cancerous cell
- the is an abnormal amount of chromosomes i a cancerous cell
- cancerous cells have chromosomes that aren't neat and ordered whereas non - cancerous cells are
Hope that helped :)
It seems that you have missed to include the necessary options for us to answer this question, so I had to look for it. Anyway, here is the answer. The group of protists that would be most likely to have cilia as adults and why is the <span>heterotrophic protists would since they use them to gather food. Hope this helps.</span>
Vesicles are used to ship materials around, into, and out of the cell. Cell membranes can pinch off in places to form vesicles, as can lysosome membranes and golgi membranes. Because mitochondria and chloroplasts are practically tiny cells within cells, I wouldn't be surprised if they had their own vesicles. If you're asking literally which organelles have vesicles inside them, I'd say the mitochondria and chloroplasts, possibly Golgi (depends on your instructor), but the cell membrane, lysosomes, and golgi can definitely make vesicles. The rough ER uses vesicles but I wouldn't consider the vesicles a part of the ER.
