Fossil Fuels and Continental drift support the idea that once continents were together.

Explanation:

  • Fossil fuels like plants, animals and rocks are of the identical features were found in the two different continents. For example, identical rocks found in the two sides of the Atlantic ocean, even the mountains in two different continents formed of the identical rocks.
  • The next one is fossils of the seed fern Glossopteris is found across all the southern continents. Hence, there is continental drift happened which caused the separation of continents.

Dmitriy789 [7]

Explanation:

D) 75 J

Energy is neither related nor destroyed- it's simply converted to different forms. Forces are vectors with both mass and acceleration; they are interactions that have the ability to change an object's motion. As objects move, their potential energy (apprx 100 J) is converted to kinetic energy. However, friction a resistive force, which is formed from the conversion of an object's kinetic energy into heat energy, as two surfaces move along each other.

With the reduction of friction, the energy output should increase, as less energy is lost as heat. Thus, the output should be 75 J.

He graph shows a trend in an ecosystem over time caused by increased pollution in the region. What can you conclude from the gra
fgiga [73]

Hi!


The correct option would be A. There's lower biodiversity among birds


Biodiversity refers to the variety of organisms (species) that inhabit a particular place, such as in our case different species of birds.

From the graph we can see that over time, the bird species are declining. From roughly 1700 bird species, the number has fallen to about 200 bird species by the middle of the fourth year.

Hence, we can deduce, and it would be accurate to say, that there is a relatively lower biodiversity amongst the birds with regard to that in the beginning.

Option B is incorrect because if the birds had a higher reproductive rate, they would be able to make up for the loss of bird species from the habitat. From the graph, we can assume that there's a moderately low reproductive rate among the birds.

Option C is incorrect because we do not know the affect of this pollution on the producers (photosynthesizing plant lifeforms). It may be possible that they might be declining, but we cannot conclude that solely from the graph.


Hope this helps!
