Explanation:
In general, tumors occur when cells divide and grow excessively in the body. Normally, the body controls cell growth and division. New cells are created to replace older ones or to perform new functions.
A testable question is something you need data for, ex: if i bounce a bouncy ball from larger heights, how high will it fly? it can't be just a regular yes or no question
Amoeba acquires it food by endocytosis, that is, a small region in the plasma membrane which ultimately forms a intra-cellular membrane-bound vescicle. It engulfs it food using its pseudopodia (temporary protrusion of the surface of the amoeboid cell used for feeding and movement) and forms a vacuole around it. When the food is already trapped inside, it releases a digestive enzyme to digest it. Intake of liquid particles is pinocytosis (cell drinking) while intake of solid particles is phagocytosis (cell eating).
Answer:
In species with polyploid, there are more chromosomal sets than in diploid one. Becouse there are more chromosomal structures available, events like mutation, recombination, DNA lose, are more probable to occur.
As the generations pass, the accumulation of these changes tend polyploid to speciation.
