The answer relates to the medium in which the sensed molecules travel. On land, animals detect a scent through organic molecules transported in the air. Land animals will experience a taste sensation by grasping an object using their mouth. Here, the organic molecules providing the sensation are transported by saliva or organic fluids of the object. So on land, there is a clear distinction between molecules transported in the wind and those that can be tasted. Water is a much more dense medium than air, and can carry small and large organic molecules, unlike air. Therefore, aquatic animals have little need for olfactory organs as all molecules can be 'tasted' from the water.
Answer:
This question lacks options, the options are:
A) storing energy
B) catalyzing cellular reactions
C) building tissue
D) storing genetic information
The answer is D.
Explanation:
There are four major biological molecules found in living systems. They are as follows: carbohydrate, protein, lipids and nucleic acids. The biomolecule being described in the question is a NUCLEIC ACID. Nucleic acids are complex biomolecules made up of long chains of monomeric units called NUCLEOTIDES.
Nucleic acids are two in nature; Ribonucleic acid (RNA) and Deoxyribonucleic acid (DNA). These two nucleic acids are involved in the storage of genetic information in all living organisms. They carry the inheritable genetic information of living organisms.
Answer:
Yea there is no diagram I can answer it if you edit the question and put a diagram.
Explanation:
The three basic steps that are common to all sensory systems are as follows:
1. They all receive sensory stimulation usually by means of specialized receptor cells.
2. They all transform the stimulations received into neural impulses.
3. They all transport the neural impulses to the appropriate section of the brain.
