Answer:
When plaque builds up, it narrows your coronary arteries, decreasing blood flow to your heart. Eventually, the decreased blood flow may cause chest pain (angina), shortness of breath, or other coronary artery disease signs and symptoms. A complete blockage can cause a heart attack
The changes in environment can cause the raising of the sea level, which can push animals further inward, which in turn destroy habit, as they began to get clumped together vegetation begins to go away, thus resulting in less species, also hotter climate makes sure that animals with very heavy coats of fur, die out pretty quickly if not cooled (over heating)<span />
The best answer is D.
Facilitated diffusion is a transport mechanism in which carrier proteins shuttle molecules across a plasma membrane without using the cell's energy . The energy is provided by the concentration gradient i.e. molecules are transported from higher to lower concentrations, into or out of the cell.
Glucose binds to carrier proteins of the GLUT family. Once bound, the change shape so as to fit in the membrane channels and thus they translocate the glucose molecule from one side of the plasma membrane to the other.
<span>Darwin's theory with relation to similarities amongst unrelated organisms looks at either similar form or similar function of appendages and from this it is postulated that some organisms have common ancestors based on these similarities. A broad example would be the fact that most vertebrates (organisms with spines) stemmed from one or a group of common ancestors, while invertebrates (lack of a spine) are related to common ancestor or groups of common ancestors. So the answer to the question is yes, it is true.</span>
