Adaptations may occur when...
MARINE SCIENCE

1.) Adaptations may occur when...
a.) an individual needs to survive a dangerous situation.
b.) an individual wants to attract a mate
c.) a species wants to move to a new environment
D.) a trait is advantageous and is passed through generations ( MY ANSWER)

2.) What role does INTRASPECIES competition play in natural selection?
a.) there is competition within a species for resources, and only some individuals will survive.
B.) there is competition within a species for resources, and only the single most fit individual will survive (MY ANSWER)
c.) there is competition between species for resources, and only one species will survive
d.) there is competition between species for resources, and only one individual per species will survive.
(I KNOW IT MUST BE EITHER (a) or (b)

3.) Look at the body shape of the picture shown below...

PICTURE WILL BE PROVIDED
Which one is best adapted to live in open water in epipelagic zone, and why?
a.) Fish A because of its elongated body and powerful tail.
b.) Fish B because of its flattened shape and eyes on the dorsal side.
C.) Fish C because of its streamlined shape and lack of pectoral fins (MY ANSWER : C because it's the darkest
Color and it just looks like the kind of fish that would be in that zone)
d.) none of these because they are sedentary

4.)Which of the following is an example of an inherited variation?
a.) An injury that results in a scar
B.)An eye color different from one's parent (MY ANSWER because it's an inherited trait the offspring could get from ancestors)
c.) A change in muscle mass due to excercise
d.) A variation in speed due to practice

Which of the following graphic organizers best compares natural selection and artificial selection
PICTURE WILL BE PROVIDED
MY ANWER : A because the others labeled below natural selection and artificial selection are wrong with the definition I'm not sure if the similarity is the same compared to D

7.) how does an environmental factor such as overfishing affect genetic factors in population?
a.) overfishing will lead to increased genetic variation.
b.) Environmental factors do no affect genetics factors
C.) Genetic traits that help fish survive are more likely to be seen in future generations. (MY ANSWER)
d.) Genetic traits that are targeted by the fishing industry are more likely to be seen in future generations

7.) Which of the following would be considered a benefit in over production?
A.) The exponential growth of a population ( MY ANSWER)
b.) the survival of the fittest due to competition of resources
c.) the exchange of genetic material between populations
d.) the change in an ecosystem due to the increased population

Answer 1

1. D. A trait is advantageous and is passed through generations

2. B. There is competition within a species for resources, and only the single

most fit individual will survive

3. C. Fish C because of its streamlined shape and lack of pectoral fins.

4. B. An eye color different from one's parent

5. A. According to graphic organizer.

6. C. Genetic traits that help fish survive are more likely to be seen in future

generations.

7. B The survival of the fittest due to competition of resources.

Answer 2

Answer 1:

The correct answer is D.

D.) a trait is advantageous and is passed through generations

There are different kind of adaptations occur in the life of organisms. Adaptations actually help organism to blend with their environment and are necessary for the survival of an organism. When organisms found a trait useful for them, they adopt it and with the passage of time they inherit that trait to their off springs.

Answer 2:

The correct answer is B.

B.) there is competition within a species for resources, and only the single most fit individual will survive

Intraspecies competition means the competition within the individual of same species and only the fittest of all the individual will survive. This is the phenomenon of natural selection, in which nature select only most fit individual for the next generations.

Answer 3:

The correct answer is C.

C.) Fish C because of its streamlined shape and lack of pectoral fins.

Epipelagic zone is the zone of the sea where most of the sunlight penetrate. It is also called sunlight zone. Fish C is best adopted here because of its streamline shape and lack of pectoral fins.

Answer 4:

The correct answer is B.

B.)An eye color different from one's parent

The inherited traits are the traits of individuals that are inherited from parents through genes. So, if an individual exhibit different eye color from his parents. It meas that he is showing inherited variation.

Answer 5:

The correct answer is "A" according to graphic organizer.

Genetics always include both natural and artificial factor so that they can examine both the natural and artificial factor in inheritance or heritable variation.

Answer 6:

The correct answer is C.

C.) Genetic traits that help fish survive are more likely to be seen in future generations.

The environmental factor such a over fishing affect genetic factors such as that only that genetic traits that help fish survive are more likely to be seen in future generations.

Answer 7:

The correct answer is B.

b.) the survival of the fittest due to competition of resources.

In the over production of a population, the survival of the fittest due to competition of resources is a benefit. Because in this way only some of the fittest individual will survive and it will reduce the over production.
