<span>#1) In order for this to occur, which of the following statements must be true?
Answer: During cellular respiration, the bonds of food molecules are broken, so energy can be released to fuel other cellular processes. In order for this to occur New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken. Therefore the correct answer is choice (A).

Answer:
<h2>C. placing carrier proteins in the membrane.</h2>
Explanation:
If there is no barrier preventing molecules from moving molecules, then there will be large movement of molecules from an area of high concentration to an area of low concentration. This passive process is known as diffusion. The phospholipid bilayer of a cell's membrane works as a barrier to large molecules, ions, and most hydrophilic molecules. Whereas small hydrophobic molecules can pass freely through the phospholipid bilayer, other molecules and ions are transported across the cell membrane with the help of transport proteins. Some transport proteins, allowing hydrophilic molecules and ions to passively move through them and across the cell membrane.
Examples: carrier proteins and channel proteins.
Placing carrier proteins in the cell membrane will allow the molecule to reach equal concentrations on the both the sides of the membrane and maintain that way over long time. In contrast, transport proteins known as pumps will use cellular energy, usually in the form of ATP, to transport molecules.
Placing equal numbers of intracellularly directed and extracellularly directed pumps would also equalize the concentrations of a molecule long over time. Pumps are to transport molecules against their concentration gradient, such as the sodium-potassium pump continuously moves sodium ions out of a cell.
Through the use of carrier proteins, there is equalization of concentrations of a hydrophilic molecule. This equalize the numbers of molecules on the inside and outside of the cell, but the pumps would continue moving the molecule inward, eventually resulting in more molecules inside of the cell than out.
Answer:
Ima say its a saturated Phospholipid but im not sure
Explanation:
Answer:
C. The North Atlantic Gyre flows in a clockwise direction, so the prevailing current on the Florida coast would be south to north, and it would disperse lionfish up the coast.
Explanation:
See the attached picture. The current that is most likely to act on lionfish near Florida would move from south to north.
Some dinosaur only ate plants and no meat. As plants became extinct the dinosaur who ate plants couldn’t get the food they need so they starved.
