Answer:
According to the characteristics given and what the image shows, the species to which the frog corresponds is Bufo boreas.
Explanation:
Options for this question are:
- <em>Bufo marinus
.</em>
- <em> Litoria caerulea
.</em>
- <em>
</em><em>Bufo boreas.
</em>
- <em>
Acris crepitans.</em>
Bufo boreas is a species belonging to the family Bufonidae, very common in North America, constituting an anuro amphibian.
The appearance of B. boreas is that of a thickened and irregular skin, due to multiple warts found on its surface. Additionally it has a stripe or line in its dorsal region, which extends from the head to the tail.
These characteristics, together with the description given, make it possible to establish that B. boreas is the species that can be observed in the picture (see image).
Quantitative data
Qualitative data does not use numbers, but names and labels
C)old or young
A dichotomous key is a tool or a used assessment that is utilized by most scientists like biologist and ecologist to organize and classify organisms into sets of classifiable structures like trees, animals, birds, cats, dogs. These are broad descriptions that systematizes a whole family of species into a set category or a whole kingdom in a simple language such as plants or animals.
In this question, we will understand the air path from entering the nasal passages to reaching the alveoli, where gas exchange takes place.
<h3>What is the air's path to the lungs?</h3>
The air penetrates through the nasal passages, passes through the pharynx, larynx and trachea, bronchi, reaching the lungs where it travels through the bronchioles until reaching the alveoli, where gas exchange takes place. The difference between inspired and expired air is in the concentration of oxygen and carbon dioxide.
a) Blood leaving the air sacs is rich in oxygen gas.
b) When exhaling, the breath is rich in carbon dioxide.
c) If you trace the path of air moving through the respiratory system, it would enter through the mouth and nose. It continues through the pharynx, into the larynx, through the tubes and into the trachea and finally reaches the lungs.
