This description is unspecific and is confusing...
The nose has different functions mainly for inhalation of oxygen and exhalation of carbon dioxide which is called the respiration process or gas exchange. As a sensory organ, the nose has also another function which is olfaction, the ability to smell.
Olfaction in a biopsychological term, is the process by which sensory information recognized by the nasal receptors are transduced in a understandable and recognizable stimulus or rather perception, in simplest term is to smell.
Therefore, nasal receptors are the structures that send messages to the facial nerve which is responsible for sending the information to the brain for it to be perceived and acknowledge.
<span>To prove his Theory of Evolution. After studying the different species of finches he found the Galapagos Islands, Darwin focused on breeding pigeons by selecting specific traits of different individuals (this is mainly a method through which different kinds of dog breeds came about). On the basis of these studies Darwin concluded that natural selection and artificial selection acted roughly in the same way. Darwin's decision to enforce a certain trait represented, in a sense, the selective pressure which is present in a natural environment (the law of the fittest).<span>

The life cycle of plants involves into two parts, first is the diploid phase and the second would be the haploid phase. Therefore, the answer would be letter A. Palm trees are known to be perennial plants and usually grows in the environment that are warm and more humid.
The type of cellular transport that does not involve the flow of particles from an area of high concentration to an area of low concentration is called the active transport.
Cellular transport of ions, gases, nutrients, waste substances and other biomolecules is of two types namely, the passive transport and the active transport. Passive transport is the movement of substances along their concentration gradient from a region of their higher concentration to the region of their lower concentration which does not require energy.
Active transport is the movement of substances against their concentration gradient from a region of their lower concentration to the region of their higher concentration. It uses energy in the form of Adenosine triphosphate (ATP). The best examples being the sodium-potassium pump in the cells and the uptake of glucose in the intestines.
I believe it would be 1. Species preservation and biological control.
