The right answer to this question is option C. the traits acted upon natural selection were genes.
At the time Charles Darwin developed the evolution theory, there wasn't a single study about genes in all science scenery, that could be explained by the lack of technology to study them and even to know they existed in the first place.
So, his theory was basically talking about adaptation, if an organism can't survive a specific environment, he'll probably die until another generation comes in and this one can survive in this environment, passing their genes to the next ones. The lack of information was the knowledge about the genes we have today, that's why most scientists take only the new Darwin theory, that includes the study of genes.
Answer:
How do the Linnaean scientific names compare to the names developed by John Ray?
Linnaean names tend to be longer
Explanation:
John Ray defined the word specie before linnaeus started his own binomial and trinomial naming of organism. John Ray definition was at specie level while Carls Linnaeus used both generic and species e.g <em>Australopeticcus africanus africanus </em>which is the first man to live
Answer:
The cell membrane
Explanation:
The cell membrane, sometimes also known as the plasma membrane, serves as a clear boundary between the inside of a cell and its outer environment.
Since it has 4 protons, it must have an atomic number of 4. (That makes it beryllium.)
Since it has a 4 protons and 5 neutrons, it has a mass number of 9.
Answer:Genetic testing involves examining your DNA, the chemical database that carries instructions for your body's functions. Genetic testing can reveal changes (mutations) in your genes that may cause illness or disease.
Although genetic testing can provide important information for diagnosing, treating and preventing illness, there are limitations. For example, if you're a healthy person, a positive result from genetic testing doesn't always mean you will develop a disease. On the other hand, in some situations, a negative result doesn't guarantee that you won't have a certain disorder.
