Answer:
A
Explanation: You can see that the green colored frogs were once lower than the blue and as time started progressing the green started getting a higher population over the blue, as the blue decreased.
During meiosis, genetic recombination may occur more than once through the process of cell division, resulting in an increase in genetic variability.
Answer;
An example of positive feedback loop is;
-When a pregnant woman begins to go into labor, the body sends hormones that increase the intensity of the labor contractions.
Explanation;
-Feedback loops are therefore the process whereby a change to the system results in an alarm which will trigger a certain result. The result will then either increase the change to the system or reduce it to bring the system back to normal.
-Feedback loops are important because they allow living organisms to maintain homeostasis (maintenance of internal environment of the body constant).
-A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction. It moves a system further away from the target of equilibrium, by amplifying the effects of a product or event and occurs when something needs to happen quickly.
Answer:
Among some of the numerical abnormalities a karyotype can detect are: Down syndrome (trisomy 21), in which an extra chromosome 21 causes distinctive facial features and intellectual disabilities. Edward syndrome (trisomy 18), in which the extra chromosome 18 translates to a high risk of death before the first birthday.
