The correct answer is -175 million years ago.
Pangaea was a supercontinent which was consisted of all the continental masses we know nowadays, just they were all merged into one very large land mass. This supercontinent started to form from the land masses that existed prior to it, and because of the tectonic activity they merged roughly around 335 million years ago. The continent existed during the Paleozoic era, as well as the early Mesozoic era.
With the breaking up of this continent because of the tectonic activity, it split initially into two large continents, Laurasia on the north, and Gondwanaland on the south. With the later break up, Laurasia split into Eurasia and North America, while Gondwanaland split into South America, India (which later moved towards Eurasia and merged with it), Antarctica, and Australia. The formation of the modern day continents also resulted in the formation of multiple oceans instead of one.
The correct answer is A. An oak tree
Explanation:
The term "primary producer" is used to describe organisms that can produce their own energy without feeding on others, this includes plants and algae that produce food and energy through photosynthesis using light and other inorganic compounds. Additionally, the primary producers can be identified because in ecosystems they are always on the first level and they are eaten by others.
According to this, the one that is a primary producer is an oak tree because this is a type of plant and therefore can produce its food through photosynthesis different to others that need to feed on other organisms to obtain energy.
Answer:
[a] 103m (I guess that it is 10^3 m)
Explanation:
To calculate how many millimeters you enter in a kilometer, just know the relationship between both units of distance.
The relationship is as follows:
1 km = 1 000 000 mm
So:
1 km = 1000 m = <u>10^3 m</u> = 10^6 mm = 1 000 000 mm
f(x) = x? & g(x) = 2x + 1
(f+g)(x) = f(x) + g(x)
= (x2) + (2x + 1)
= x2 + 2x + 1,
(f + g) (x) = x2 + 2x + 1
(f-g)(x) = f(x) - g(x)
= (x2) - (2x + 1)
Covergent plate boundary occurs.
