The Law of Dominance says that when an organism is heterozygous for a trait, only the dominant allele will produce a phenotype.
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.
Answer:
Force is a measure of power. Velocity, on the other hand, is a quality an object has. Apply force to an object, and its velocity changes.
Answer: B. cerebellum
When the cerebellum is
damage, it will result to cause problems in terms of coordination and balance. The
cerebellum is very similar to cerebrum having highly folded surface and has two
hemispheres. It is mainly associated with regulation and coordination of
balance, posture, movement, vasomotor and respiratory centers.
