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.
The liquid needed for oxygen humidifier would be sterile water.
When administering a high dose of oxygen(>6lpm) it is important to use a humidifier so the air that enters the lungs is humid enough so it won't dry the airway. Sterile water is best because there is a chance that bacteria from water will enter the airway. Impurities in water are not harmful to the body but it might damage the machine, so distilled water would be best.
Acute endocarditis is most commonly contracted through - parenteral entry
By the phrase Parenteral entry, it is indicates that the infection occurs on introduction of infected blood or body fluids into the body. As indicated by name, endocarditis is the infection occurring in endocardium, the innermost layer in heart.
It is an infection caused by microorganisms, when incorporated into blood via mentioned route. The microorganisms in blood reach the heart and effect the heart valves. Common examples of the causative agents are <em>Staphylococcus aureus, </em>Brucella, Listeria, Candida etc.
The condition involves inflammation of endocardium with signs including shortness of joint and muscle pain, breath, fatigue etc. The treatment method involves antibiotics and surgery if required.

Answer:
A theory to explain the mechanism of enzymatic reactions, in which it is proposed that the enzyme and substrate(s) bind temporarily to form an enzyme–substrate complex. The binding site on the enzyme is known as the 'active site' and is structurally complementary to the substrate(s).

Answer:
Mutation
Explanation:
Mutations can be defined as changes in genetic material, which are the main source of existing genetic variation. For ensuring genetic variability, that is, ensuring that individuals have different DNA, mutations are considered an important point in the evolution of living beings.
It is through mutations that important adaptive characteristics emerge, in addition to essential characteristics remaining in species that are different but that have similarities.
These processes also guarantees the selection of species most adapted species. Mutations can be beneficial, neutral or harmful (genetic diseases or genetic "failures") and, therefore, are not targeted, occurring at <u>random</u>.
