A mutation is a permanent change in the DNA sequence of a gene. This can be beneficial if the change gives a new function to or improves the function of that gene.
<span>The above is a definition. But one must really define "beneficial". Some regard it as beneficial if it helps the specific individual who has it. Others would think it beneficial if it produced some survival advantage that insured more descendents for that individual. </span>
<span>It is the difference between a mutation that allowed for greater athletic ability, but a decreased desire for offspring, versus a more moderate athletic enhancement, but a greater desire for offspring. </span>
<span>The small percentage of ways to improve an organism, versus the near infinite ways of harming the organism, mean that most mutations are not going to be beneficial. At best, they will be "inconsequential" - such as a new shade of eye color, or a mole on a section of your skin. </span>
The populist notion of "powers" that can come from mutations is wildly inaccurate. Even assuming a minor power like the ability to see infra red radiation would take thousands upon thousands of mutations over vast amounts of time. A mutation for blindness is far more likely.
<span>It should also be noted that the traditional model of evolutionary theory no longer applies to man. We don't allow changes in our environment, and without such changes, there is no need for one trait more than another to predominate. After all, it is irrelevent that a mutation might allow for greater speed in running, when everyone drives a car.</span>
Answer:
Accuracy is being able to hit close to or right around the designated area, precision is being able to hit it dead on
Answer:
c
Explanation:
it weakens an ecosystem.biodiversity is the slight changes of one organisim to the next inside a species. when a species looses biodiversity, the traits that the one organisim had are gone and none of the others can adapt this trait. adaptation is what keeps speicies alive. thus, loss of biodiversity is bad and weakens an ecosystem.
Answer:
the outer membrane has small organic molecules but the inner membrane is less permeable and studded with transport proteins.
Explanation:
Answer:
D) Neither of the parental genes is dominate over the other.
Explanation:
<em>Since the trait on the offspring is a mixture from both parent, it means that neither of the alleles from both parents is completely dominant over the other. Instead, each of the alleles contributes equally to the trait of the offspring.</em>
This effectively explains the fact that each trait exhibited by offspring is a blend of the traits from the two parents.
The correct option is D.
