The answer is: mitochondria.
Mitochondria produces adenosine triphosphate (ATP), a molecule that the cells use as a source of energy. Through a process called cellular respiration, the mitochondria oxidases glucose to obtain the ATP. There are three main steps to this process: glycolysis, the Krebs cycle, and ATP Synthesis.
Like chromosomes, genes also come in pairs. Each of your parents has two copies of each of their genes, and each parent passes along just one copy to make up the genes you have. Genes that are passed on to you determine many of your traits, such as your hair color and skin color.

Answer:
thats just how the cookie crumbles.
Explanation:
While some species evolve, due to a thriving enviroment and cross breeding, the world is dying. Millions of habitats have been destroyed, causing some animals to not survive in the wild. Like pandas, when their homes were being destroyed, they starved. When they starved, they didn't reproduce. On and on and on.
Answer:
The correct answer is option B, that is, an endoskeleton evolved to enclose the dorsal nerve cord, which develops from the notochord.
Explanation:
It has been discovered that the ancestors of the modern-day fish were vertebrate chordates. The vertebrate chordates are considered to have evolved from the invertebrate chordates that are identical to the present day tunicates. It has been found that in vertebrates the endoskeleton has evolved to encompass the dorsal nerve cord that has been developed from the notochord (a characteristic of invertebrates).
Answer:
ever wonder if your dog really really loves you — or if he’s just in it for the kibbles?
Alas, scientists haven’t figured out exactly how our dogs feel about us. But a study published this week in the journal PLOS One has yielded fresh insight into how dogs see us. It adds to existing research showing that — much like humans, other primates and even goats — our canine friends use specific regions of their brain to “process” our faces.
“Our study provides evidence that human faces are truly special for dogs, as it involves particular brain activity,” study co-author Dr. Luis Concha, an associate professor at the National Autonomous University of Mexico’s Institute of Neurobiology, told The Huffington Post in an email. “To dogs, the human face is no ordinary thing.”
