Their sex chromosomes or gender doesn't play a role in determining whether the cancer is from exposure to carcinogens. usually,an abnormality in sex chromosomes leads to hereditary type cancers inherited fro their parents, but with carcinogens they dont have a very major role to play with.Rest 3 options would surely determine an individual getting cancer from carcinogen.
Natural selection is the process through which species adapt to their environments
natural selection is the method through which populations of dwelling organisms and species adapt and exchange. individuals in a population are obviously variable, that means that they will be all unique in a few methods. this variation approach that some humans have trends higher suited to the environment than others. people with adaptive tendencies—traits that supply them a few advantage—are more likely to live to tell the tale and reproduce. those humans then pass the adaptive developments directly to their offspring. over the years, the ones powerful trends come to be more not unusual within the populace. through this machine of natural selection, favorable trends are transmitted through generations.
natural selection can cause speciation, in which one species offers rise to a brand new and rather precise species. it is one of the processes that drives evolution and permits to provide an cause of the sort of existence inside the world
Darwin selected the decision natural choice to contrast with “artificia selection,” or selective breeding that is controlled via human beings..

Question: Which pituitary hormone causes liver cells to release somatomedins that increase the rate of uptake of amino acids by cells such as skeletal muscle fibers?
follicle-stimulating hormone
prolactin
thyroid-stimulating hormone
growth hormone
Answer:
growth hormone
Explanation:
Somatomedins are growth factors. The growth hormone makes the cells such as liver cells, skeletal muscles, bones, etc. to secrete the somatomedins. The somatomedins from the liver enter the bloodstream to reach the target cells. The somatomedins make the skeletal muscles, bones, etc. to absorb amino acids into the cells so as to facilitate protein synthesis. This growth factor also downregulates the breakdown of proteins. This is how growth hormone triggers the growth of muscles and soft tissues.
