Answer:
To better understand why GMOs were initially created, we have to take a look at the evolution of crop modification and how we got the foods we eat today. Farmers have intentionally changed the genetic makeup of all the crops they have grown and their livestock since domestic agriculture began 10,000 years ago.
Explanation:
My answer -
<span>There are typically two
planets that are dubbed as Earth's twin. The first one, Venus, is called
Earth's twin because of its similar size, and how it is the closest
planet to Earth. But, scientists discovered that Venus's atmosphere and
temperature were totally different from Earth's. The other planet also
called Earth's twin is Mars. Mars is believed to have a large ocean on
the past. Some even say that life may have developed on Mars for a short
period of time. Furthermore, Mars has an average temperature of -70
degrees Fahrenheit, closest to Earth than any other planet. It seems that
water and life define the Earth, and if Mars has these characteristics,
it would truly be Earth's twin.
P.S
Have an AWESOME!! day :)

Question 1: The correct answer should be the one that shows the producer first, (->) followed by the herbivore, (->) with the carnivore last.
Producers are organisms that harvest their own 'food' using things like the sunlight and water. Examples of producers are grass and other vegetation.
The herbivore, or an organism that consumes only vegetation and/or algae, consumes the producer.
⇒
The carnivore consumes meat, or other animals such as the herbivore. It's the last.
⇒
⇒
Therefore the answer is
B.

Question 2: I'm pretty sure that succession as well as regrowth after volcanic eruption (Just look at Mount St. Helens. After 30-35 years after the eruption, nature is
still recovering) happens over time/slowly. I would say global warming [C](?) would be the answer.
Exothermic reactions lose heat and are hot to the touch (Think explosion)
Endothermic reactions gain heat and are cold to the touch (Think of an instant ice pack where you pop it to make it cold)
