Traits that are heritable are more likely to respond to selection, as they can be passed down from one generation to the next. Non-heritable traits are less likely to respond to selection, as they are not influenced by genetic factors.
If new technologies challenge our current understanding of natural selection, scientists would likely conduct further research and experiments to validate the new information. This might lead to revisions and updates in scientific principles related to natural selection. The scientific community would engage in debates and discussions to reconcile the new findings with existing theories. Ultimately, this process would contribute to a deeper and more comprehensive understanding of evolution and natural selection.
Natural selection may ultimately be his downfall.
Selection operates on the phenotype, which is the observable characteristics of an organism. Organisms with certain phenotypic traits that increase their fitness are more likely to survive and reproduce, passing on their advantageous traits to the next generation.
Natural selection and sexual selection are both mechanisms that drive evolution, but they differ in how they shape species. Natural selection is based on survival and reproduction, where individuals with advantageous traits are more likely to survive and pass on their genes. Sexual selection, on the other hand, is based on traits that increase an individual's chances of mating, such as elaborate displays or physical characteristics. While natural selection focuses on survival, sexual selection focuses on reproductive success and mate choice.

The D antigen is considered the major antigen of the Rh system because it is the most immunogenic component, meaning it is the most likely to provoke an immune response when introduced into an Rh-negative individual. The presence or absence of the D antigen determines a person's Rh blood type, which is crucial for blood transfusions and pregnancy, as Rh incompatibility can lead to serious complications. Additionally, the D antigen's prevalence in the population makes it a key focus in blood typing and transfusion protocols.
natural selection
The T cell enters a state of anergy. In this case, the T cell becomes tolerant to that antigen and is unable to divide or to secrete cytokines. This state of unresponsiveness to antigen is called anergy.
antigen. Helper B and T cells most likely.
Dolphins.
The likely word is "challenge" (a test, contest, or duel).
Answer Class II MHC protein. Class II are found in membranes of antigen-presenting cells-phagocytic cells and lymphocytes. The liver performs phagocytosis and antigen presentation.
Anyone can challenge anyone! But likely than not the right person will prevail.
