The one that makes the most sense to me, would have to be B. A would not be a benefit at all. While C doesn't necessarily makes sense as the device is only designed to capture energy from ocean waves. And D doesn't make sense to me in general.

A student draws a fence with several gate as part of a model of cellular transport explain what defence indicates represent blam
Oksi-84 [34.3K]

The given question says that a student has constructed a model of cellular transport using fences and several gates.  

This model can be used to demonstrate the cellular transport.

The gates of the fences can be supposed as the protein pumps and the other fence demonstrates the lipid bilayer.  

Let’s suppose in the fence, there are many cattles, and outside, there are less cattles, but the student open the gate and bring more cattles inside the fence. In this case, the transport of the cattles is similar to the active transport of the molecules using protein pumps. At cellular level, the energy for the active transport is provided by ATP molecules.

Now, let’s say, the student wants to feed the cattles with some nutrition rich food, which can help in maintaining the health of the cattles. The student fills his car with the cattle food and he enters inside the fence through gates. In this case, the food was not present in the fence, but was abundant in the outside environment, so, the diffusion would occur. But food cannot come self, without help of others, so, the movement is facilitated by the car, as it is done by the carrier proteins. Hence, it is an example of facilitated diffusion.

3. Which is not an example of symbiosis?
S_A_V [24]

Answer:

The correct answer is B. generalism.

Explanation:

Mutualism is a symbiotic relationship wherein both organisms benefit from the other’s presence. Parasitism is a symbiotic relationship wherein one organism benefits at the expense of the other organism, which is harmed. Finally, commensalism is a symbiotic relationship wherein one organism benefits and the other is neither helped nor harmed. Generalism does not refer to a symbiotic relationship and thus is the correct response.

Hope this helps!
