Question 2 of 10 which structure is most likely used for motion?

Answers

The structure that is most likely used for motion is the tail fin of the fish. The correct option is B.

What is motion?

Motion is changing or modifying an object when applying a force. The living body move or locomote with the locomotion organ. These are different types of locomotion organs in different organs.

There are different organs in different animals for locomotion and motion. In humans there are legs, in animals there are paws and in fishes, there are fins, in insects, there are wings and legs.

There is no movement made by the leaf. The dolphin swims with the assistance of its tail, which is moved up and down and in other directions. It is not used to move the apple. The wolf's eye is for sight alone, not for movement.

Thus, the correct option is B. the tail fin of the fish.

A scientist has been tracking and studying a population of deer in Yellowstone National Park. He surveys the population every six months. Usually, the population is thriving and has a gene pool with a wide variety of traits. But during one six-month period, an event occurred that affected the population, and when the scientist returned, the amount of genetic variation had decreased significantly. Which of the following is most likely the event that occurred to change the population? Yellowstone National Park expanded its borders.

Answers

Hi,

I think that you're missing some options, but here they are (let me know if I'm right!

-A population of wolves was introduced
-The amount of disease in the deer population decreased
-More grass was planted

Now, if the gene diversity decreased, it means that a lot of deer died. This could happen because wolves were introduced -this is the correct answer, and the wolves ate some deer.

It may be due to the fact that there was an event that eliminated many of the individuals in species.

What is genetic variation?

The term genetic variation refers to the occurence of organisms in a specie that are composed of different genotypes.

If the genetic variation in a population at the yellowstone park is decreased it may be due to the fact that there was an event that eliminated many of the individuals in species.

What are the parts or process that can describe an ecosystem?a. chemical changes and flow of energy
b. chemical changes and flow of water
c. physical changes and flow of energy
d. physical changes and flow of water

Answers

Answer:

a. chemical changes and flow of energy

Explanation:

Energy flow from one organisms of one tropic level to other, matter cycling and transformation of energy are the functions that sustain the ecosystem. Transformation of solar energy into chemical energy by plants serves as energy source for all heterotrophic living beings in the system. The heterotrophic organisms digest the ingested food (chemical change) to release energy to support their life processes. The energy stored at one tropic level is carried to next tropic level via food chain and food webs and represents the interaction between living components of ecosystem.
