Answer:
genetic modification competitors increase
Explanation:
The fish developed the gills because of <em>genetic modification</em>. Because the fish are now able to swim in deep water, their <em>competitors</em> in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will <em>increase</em>.
Answer:
The correct answer is "uranium-238".
Explanation:
Uranium-238, is the most abundant isotope of the element uranium. Uranium-238 has not enough nuclear force to balance electrostatic forces between protons, and as a result, it is a radioactive isotope and its losing energy because of the spontaneous breakdown of its atomic nucleus. Uranium-238 has a half-life of 4.5 billion years and is used as fuel in nuclear reactors as well as for dating purposes.
The answers are principles C and D. After the big bang, particles in gas clouds were closer to each other and clumped up faster. As they clumped together, they gained more gravitational force, eventually creating asteroids, stars, and planets.
