The answer is 2. Natural selection is defined as the action by which organisms pass on offsprings the improved chance of surviving and reproduction. This is due to the differences in their phenotypes and only those with favorable traits have the ability to survive.

2

The answer is 3. Mutations in the gametes can be passed on to the next generation because both egg and sperm cells contribute to giving half of each chromosome.

3

The answer is 3. An organism with a low survival value is more likely to not survive. Only those with favorable characteristics are more likely to produce offsprings with the ability to adapt to the changing environment.

3

The answer is 3. Mutations are changes in DNA and may be spontaneous wherein the original strand is replaced with another or added with a new one. Another way wherein mutations arise is by inducing a response created by exposure to chemicals or radiation.

3

The answer is 2. If two different species have 95% of the same DNA sequence, this may probably suggest that they have the same protein structure or amino acids, the unit of DNA.

2

The answer is 3. Extinction is the cessation of the last type of a specific individual or a group of species. This means that the capability to reproduce and survive are also lost.

3

The answer is 3. As we can see in the diagram, after 10 years, the spotted species shows an increase in number. This is due to the fact that this organism underwent natural selection successfully.

3

The answer is 4. Natural selection is defined as the action by which organisms pass on offsprings the improved chance of surviving and reproduction. This is due to the differences in their phenotypes.

4

The answer is 3. Overproduction is when a certain species release reproductive products in order to produce a lot of offsprings. This is done in cases when a species needs to adapt to the environment. Hundreds are released because some of these products will not be able to survive and some will and it is to make sure that there would be products that will be successfully produced.

The answer is 3. According to the data given, the light colored moths were closest to the dark colored moths at the end of year 5 with the light colored moths amounting to 246 and the dark colored moths with 281.

3

The answer is 4. Due to the changing environment, the dark colored moths had more chance of survival by their ability to camouflage. The change was due to the pollution making the bark of the trees darker making it favorable for the dark colored moths.

4

The answer is 1. Natural selection is defined as the action by which organisms pass on offsprings the improved chance of surviving and reproduction. This is due to the differences in their phenotypes.

1

The answer is 4. This is a result from mutation which is caused by the need to adapt to the changing environment. The process of natural selection is done.

4

The answer is 1. During the time when the grass was still green, straw colored crickets proliferated in the environment, but once the grass mutated for its survival, the straw colored crickets had a decrease in their population.

1

The answer is 2. Natural selection is defined as the action by which organisms pass on offsprings the improved chance of surviving and reproduction. This is due to the differences in their phenotypes.

2

The answer is 3. Since the straw colored crickets survived the green meadow by adapting, they have proliferated and increased in number compared to the red colored ones.

The species could become extinct. Without natural selection, the ability adapt to certain modifications in the environment such as climate, temperature, habitat and predation could be hard to survive in without natural selection.

Genetic variation may be due to mutation, which is the ability of a unique gene to undergo changes due to exposure to the environment or an abnormality in process. It may also be achieved by sexual reproduction wherein half of the traits from both parents combine to form another unique trait.

This would create a large competition for the population if all hawks in the population develop this kind of ability. But on the other hand, there would be an increase in survival for their species.

The survival of various individuals would be increased but there are still individuals that might not be successful in survival.

The frequency would change most likely every time the survival rate decreases due to the changing environment and the lesser ability to adapt.

Stll, the ability to survive with a keen eyesight could also still be increased. Another type of adaptation would occur for the weak muscle wings.

The ability of surviving predation of the leatherback turtles by digging two holes for the manipulation of the predator.

This modern behavior can be explained by natural selection wherein the ability to adapt to a changing environment is by producing offsprings with mutated genes for the survival of the new generation.

The combination of the chemical and the color of the monarch butterfly are ways on how to survive predation or the risks in the environment. It is a way of defense mechanism to avoid being eaten..

The combination of the chemical and the color of the monarch butterfly are ways on how to survive predation or the risks in the environment. It is a way of defense mechanism to avoid being eaten.

Since the viceroy has the same size, shape, and coloration as with the monarch, the deception of the viceroy to the predators, making the predators think that the viceroy is a monarch, makes the predator avoid the viceroy, hence aid in survival.

Overproduction is when a certain organism lays hundred of eggs in order to make sure that some of them will survive. Overproducing would cause an increase chance of survival.

The difference or variety in DNA in a genetic makeup of a certain plant or animal is called genetic diversity. It is a way of organisms to adapt to an environment.

Natural selection is defined as the action by which organisms pass on offsprings the improved chance of surviving and reproduction. This is due to the differences in their phenotypes.

Adaptation is the process wherein an organism undergoes change to better fit in the new environment or an occurred change in the environment. This usually happens when organisms transfer into a new habitat or when temperature changes.

One possible cause of the genetic variation is mutation. Mutation that can be triggered by the inability to survive in the changing environment, thus dandelions underwent mutation.

The reason why dandelions have not yet spread to other areas is because they have adapted to that kind of environment. The ability to survive in that kind of environment makes it easier for them.

The amount of grass was decreasing and the amount of dandelions were increasing because the dandelions have already established a foundation wherein they have a greater chance of survival compared to the grass.

The advantage of short dandelions over the tall dandelions is the ability of the short dandelions to survive more than the tall ones. As stated in the story, the short dandelions were able to prevent from being lawned.

The original event by which insects became resistant to insecticides is when the insects became vulnerable to the insecticide thus underwent natural selection or mutation in order to survive and become resistant again.

The rate of percentage of resistant insects increased because organisms undergo a process called natural selection

Another form of insecticide include biological insecticide. It is a process by which a certain organism is introduced and specifically kills the insects pestering the harvests or fruits but without damaging the harvest.
