Hello. Your question is incomplete. However, when researching, I managed to find a question like yours and found that you forgot to mention that the question wants you to determine which is the best reference point in this scenario.
Answer:
The best point of reference is the starting position of the toy car.
Explanation:
To study the movement of the car it is necessary for Sudhi to establish a reference point, so that she can calculate all the variables associated with this movement. The best variable in this scenario is the starting position of the car, when it is still on the ramp. Thus, Sudhi needs to determine the distance between the car and the ground, that is, what the car's starting position is. She will be able to discover this when determining the height of the ramp.
<span> Organism- an individual form of life that is capable of growing metabolizing nutrients, and usually reproducing. </span>regardless of the organism being unicellular or multicellular.
The answer is: the legumes will extinct, too.
It is known that plants cannot directly use atmospheric nitrogen. But, some legumes have a symbiotic relationship with bacteria that live in their root system. These bacteria are called Rhizobia and have the ability of nitrogen-fixation. In the root nodules, they use atmospheric nitrogen to convert it into ammonia, and later to ammonium, which can be used by plants. When legumes die, nitrogen from their remaining is released back to the soil where it is available to the other plants.
So, if <span>Rhizobia suddenly became extinct, the symbiotic relationship between will be interrupted. The legumes will not be able to use atmospheric nitrogen without the help of Rhizobia, and eventually, they will extinct, too.</span>

Answer:
Letter B.
Explanation:
Aquaporins, also known as "water channels," are the main transport of water through the membranes of plant, animal, and bacterial cells. These channels allow the water to travel into and within cells and, at the same time, exclude the passage of ions and solutes.
What makes letter B the correct answer, is the form of transport and shape of the channel that allow water according to the osmotic gradient. In this model, letter A shows simple diffusion, while C and D seem to illustrate gated channels.
