Cladistics<span> is an approach used for biological classification in which organisms are categorized based on their shared characteristics that can be used to traced to a group's most recent common ancestor.</span>
Answer:
<em>The correct option is C) C-shaped cartilage rings </em>
Explanation:
The trachea is commonly known as the wind-pipe. The trachea can be described as about a 4 inch long passage from which the air travels into the bronchi and lungs. The pathway of the trachea is kept open by C- shaped cartilages which are lined all over in the trachea. The C-shaped cartilages protects as well as maintain the shape of the wind-pipe. The rigidity of the trachea arises from the C-shaped cartilages.
Answer:
Relative dating is the technique to calculate the age of an ancient materials in comparison to another material's age. Layer A is less older, if layer B lies beneath it. Layer A may be 2.5 to 3 million years old.
Explanation:
Before discovery of radioactive carbon dating method, geologists make use of relative dating method in order to determine the age of rock or fossils. The relative dating procedure often referred to as stratigraphy. Though this procedure is not capable of predict absolute age or dating. In relative dating, is mainly based on the fact that the older rock layers will be deeper in respect to the less older rock layer.
Trans-neptunian Objects (TNO) is a planet in our solar system. The first TNO discovered was Pluto. TNOs are classified into two groups:
1. Kuiper Belt Objects
2. Scattered Disc Objects
There are various TNOs discovered till date some of which are:
1. Pluto
2. Lempo
3. 90482 Orcus
4. 136199 Eris
Answer: Pluto is a TNO with the most eccentric orbit.
The best way to classify an interaction between titmouse and a chickadee living in the same territory and using some of the same resources is competition.
<h3>What is competition?</h3>
Competition is an interaction between living organisms or species in which both require a resource that is scarce in supply.
According to this question, a titmouse and a chickadee are living in the same territory and are using some of the same resources.
This suggests that the interaction between titmouse and a chickadee living in the same territory and using some of the same resources is competition.
