<span>In getting her plants to grow, the gardener should use the color blue for her colored translucent sheets. The reason for this is because it will be absorbed by the plants, causing them to get the light absorption that they so desperately need. Other colors, such as green, are absorbed into plants (as can be observed by their green colors), and thus they do not absorb the light through this color.</span>
Answer:
The species is not prey to what is already living there and as a result may reproduce uncontrollably and end up causing the other species to go extinct by stealing the resources they need.
Explanation:
The digeorge syndrome is a genetic disorder, which caused by the deletion in the chromosome number 22. This disease is characterized by the congenital heart disease, immunodeficiency, and hypocalcemia.
In this case, the most frequent clinical manifestation is hypocalcemia. Hypocalcemia is the condition, in which the blood calcium level would be declined to a significant level.
Answer:
The correct answer is option B. pheromones.
Explanation:
Pheromones are chemical substances that are released and produced by a different type of animals, into the environment, for marking their territory or affecting behaving of its species.
Wolves communicate by the chemical messages using their sense of smell. Such chemical messages are called pheromones, between different members of the same species.
Thus, the correct answer is option B. pheromones.
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.
