I would say A just because if your dad has a genetic disease and you mom does not have it you have about a 50 50 chance of having that disease in a perfect control that's assuming that its recessive and that your moms side does not present this disease
that's how its always been taught to me
Answer:
The functional units of dna that contain the instructions for making one or more proteins are the "Genes".
Radioactive decay (also known as nuclear decay, radioactivity or nuclear radiation) is the process by which an unstable atomic nucleus loses energy (in terms of mass in its rest frame) by emitting radiation, such as an alpha particle, beta particle with neutrino or only a neutrino in the case of electron capture, or a gamma ray or electron in the case of internal conversion. A material containing such unstable nuclei is considered radioactive. Certain highly excited short-lived nuclear states can decay through neutron emission, or more rarely, proton emission.
Answer: c.Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.
Natural selection is the differential survival and reproduction of individuals because of differences in the phenotype. Phenotypic characteristics favors the survival of some organisms in the population better than others. Example given by Darwin population of colored beetles green and red belonging to same species. Green ones mimic the color of grass not noticed by birds but red ones were noticed and eaten by birds. This is the selection by nature for better suited individuals. Green color gave the survival advantage to these beetles which is a phenotypic characteristic therefore, they will produce more offsprings than the red ones and also pass on the phenotypic trait to their offsprings.
