, Of the following biomes which one do many scientists consider provides the most

According to the biological species concept what is the important thing determining
members of a species? ANSWER That the individuals can reproduce and the offspring
are fertile
Which level of biodiversity is essential to the process of Natural Selection? Choose the
best answer. - ANSWER genetic diversity
Which of the following is TRUE? - ANSWER Mutations are how new traits or versions of
traits are created.
Which of the following is always TRUE of biological evolution? - ANSWER it occurs over
generations
sexual selection ANSWER This can lead to characteristics in a population that are not
necessarily good for survival but are good for getting a mate
darwinian fitness ANSWER This describes an individual's genetic contribution to the
next generation, and often is measured by the number of offspring an individual has
natural selection - This is where the environment constitutes the selection pressure
adaptation - We could use this term when referring to a trait of resistance to insecticide
in a mosquito constituting a population that is being sprayed by an insecticide.
Allopatric Speciation - ANSWER mode of speciation that occurs when biological
populations of the same species become isolated from each other to an extent that
prevents or interferes with genetic interchange.
