In multicellular organisms, the body is a system of multiple, interacting subsystems. Subsystems are groups of cells that work together to form tissues. Interactions are limited to the circulatory, excretory, digestive, respiratory, muscular, and nervous systems.
I believe the correct response would be B. Since of evolution were to occur, the possibility of the geographically isolated snakes to reproduce would be 0. Since the gene pool or the collection of all the genes in the population were to change and as a result of future reproductions of the 2 populations over time, transmission of specific genes that code for traits were to be specific for that population, ultimately not allowing them to reproduce.
Answer: D is right
Explanation: It seems both waves have same wavelength.
Because speed = wavelength · frequency (v = λf) and
f = v/λ, so frequency is same. Because period T = 1/ frequency, also periods are same. Wave Y has higher amplidude and its energy is greater.
