Ans.
<em>Viscum album </em>is a plant species, commonly known as mistletoe. It is a hemi-parasitic plant that grows on other trees.
Birds cause seed dispersal as they pick seeds from parent plant and drop them in other places. Seeds of mistletoe are sticky or viscous due to mucus and they provide nutritious food to the birds.
Hence, it can be concluded that the mistletoe seeds show adaptations primarily for seed dispersion, not for infecting the host plant.
Thus, the correct answer to be filled in the blank is 'is nutritious to the dispersing birds.'
Answer:
The ultimate level of causation refers to the behavior’s evolutionary significance; how the behavior enhances reproductive fitness. The proximate cause refers to the immediate cause of a behavior, whether that be hormonal, neurological, cognitive, interpersonal, or cultural. For example, the proximate cause of humans eating more cookies, cake, and ice cream involves the psychological tendency to desire and enjoy foods with high sugar and fat content. The ultimate cause involves the high caloric content of both sweet and high fat foods, which promotes physical survival in resource-scarce environments.
Answer:
Provides body tissues with oxygen
Explanation:
The respiratory system supplies oxygen and removes carbon dioxide from the body, assisting cells in metabolism, acting in conjunction with the circulatory system, providing oxygen to body tissues. In addition, this system is related to smell, that is, our ability to allow odors and also related to speech, due to the presence of so-called vocal folds in one of the organs of the respiratory system.
This system is formed by the nose, nose cavity, pharynx, larynx, trachea, bronchi and lungs.
