The flower mechanism that would not help them preventing pollination by a specie such as a foreign plant would be that the flowers of different species are then the same color and would attract the same pollinators.Hope this would be of help.
I think that the answer is behavioral isolation because this isolation helps members of the same species identify each other as mates and that's what the emperor penguins do.They call their mate with a specific sound.I'm not 100% sure tho
Some allergens act directly as antigens, and the immune system recognizes them as foreign, stimulating the production of specific antibodies.

What is immune system?</h3>
- The body's defense against infection is provided by the immune system, a complex network of organs, cells, and proteins that also safeguards the body's own cells.
- Every germ (microbe) that the immune system has ever eliminated is recorded, allowing it to promptly identify and eliminate the microbe if it re-enters the body.
- Flu, mono (mononucleosis), and measles illnesses can temporarily impair immune function.
- Additionally, unhealthy eating habits, alcoholism, and smoking might impair your immune system.
- Since the many types of immune system cells are produced in the bone marrow, if the immune system were a police force, it would be the police academy.
- In the bone marrow, stem cells, a common type of beginning cell, are used to develop all immune system cells.

Salt water is denser than cold water because fresh water sinks when it is in salt water.
Genes B and C with 10% recombination frequency are closest to each other. Because recombination happens at random, the distance between genes that are farther from each other creates higher recombination frequency. A low recombination frequency of 10% means the genes are closest to each other. The short distance between the two genes allow fewer recombination to happen, thus the frequency is low.
