The populations with the trophic levels that receive the least amount of the total energy from the grass would be Hognose snakes and owls.
<h3>Trophic Level</h3>
The higher we move up a trophic level, the lower the amount of energy transferred from the previous levels.
More precisely put, only about 10% of the total energy available at one trophic level is transferred to the next while the rest is lost as heat to the surrounding.
In this case, Hognose snakes and owls represent the two highest trophic levels in the ecosystem. Thus, their populations would receive the lowest amount of energy from the producer, the grass.

Answer:
Facilitated diffusion.
The cell with mutated membrane proteins can not transport calcium ions. Simple diffusion does not use membrane proteins to transport the substances.
Explanation:
Simple diffusion differs from facilitated diffusion in not using any membrane protein to transport the substances. Both simple and facilitated diffusion move the substances down their concentration gradient in a passive process.
However, facilitated diffusion makes use of integral membrane proteins to allow the charged or polar molecules to cross the membrane. These integral membrane proteins serve as channel or carrier and allow the polar and charged substances to cross the non-polar core of the membrane.
Calcium ions are charged particles and can not cross the non-polar core of the membrane. The cells with mutated membrane-bound proteins are not able to transport these ions. This suggests that calcium ions were moved across the membrane by facilitated diffusion through the wild type membrane-bound protein.
Would the correct answer be A
Answer:
True
Explanation:
both lipids and carbohydrates contain:
-Carbon
-Hydrogen
-Oxygen
The answer is secretory vessicles. They transport the modified proteins and lipids from the Golgi apparatus to the outside of the cells. They are especially abundant in secretory cells. They bud from the trans side of the Golgi apparatus. Golgi apparatus are flattened disks of the membrane with cisternae. They transport, fold and modify proteins and lipids in a cell. The cis side of Golgi apparatus is located in close proximity to the endoplasmic reticulum that manufactures the proteins and lipids.
