I believe (B) is the best option due that it mentions the reason causing natural selection with limited supplies competition increases making it more likely for the strongest individuals to survive
i think the answer is D) but you should get someone else to confirm this.
Answer:
It is the center of the solar system.
It is made up mostly of gases, not solids.
It is the most massive object in the solar system.
Explanation: The sun is only about 4 billion years old so the 3rd one is incorrect, and the last one is incorrect because the Sun is made up of mostly hydrogen
Answer:
A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions. Shared electrons located in the space between the two nuclei are called bonding electrons. The bonded pair is the “glue” that holds the atoms together in molecular units.
<span>You've gotten 2 different answers so far and both can be considered correct. It depends on the source. Some books/teachers give 5 steps: .....glycolysis -> transition reaction -> Krebs cycle -> electron transport system -> chemiosmosis Some books/teachers don't list the transition reaction as a separate step, considering it as a minor setup step for the "real" second step, the Krebs cycle. .....glycolysis -> Krebs cycle -> electron transport system -> chemiosmosis Some books/teachers (wrongly) list only 3 steps as follows. .....glycolysis -> Krebs cycle -> electron transport system That's wrong because the electron transport system doesn't make any ATP: it just sets up the proton gradient that chemiosmosis uses to create the ATP. If the steps are to be collapsed into just 3, then the correct formulation would be: .....glycolysis -> Krebs cycle -> oxidative phosphorylation</span>
