Answer:
The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history. In land animals the respiratory surface is internalized as linings of the lungs. Gas exchange in the lungs occurs in millions of small air sacs; in mammals and reptiles these are called alveoli, and in birds they are known as atria. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood. These air sacs communicate with the external environment via a system of airways, or hollow tubes, of which the largest is the trachea, which branches in the middle of the chest into the two main bronchi. These enter the lungs where they branch into progressively narrower secondary and tertiary bronchi that branch into numerous smaller tubes, the bronchioles. In birds the bronchioles are termed parabronchi. It is the bronchioles, or parabronchi that generally open into the microscopic alveoli in mammals and atria in birds. Air has to be pumped from the environment into the alveoli or atria by the process of breathing which involves the muscles of respiration.

Answer: herbivore, eukaryote, primary consumer
Explanation:
The red squirrel can be described by the following features.
1. Herbivore: A herbivore is an animal which is dependent upon the plant and their products for it's food requirement. Here, the red squirrel is the herbivore because it is dependent upon the spruce tree seeds for their food requirement.
2. Eukaryote: A eukaryotic organism is the one which has well define nucleus and encloses the genetic material in the nucleus. The red squirrel is a complex eukaryotic organism.
3. Primary consumer: In a food chain a primary consumer is an organism which is dependent upon plants and their food products for energy and food needs. The red squirrel is the primary consumer this is because of the fact that it consumes on the seeds of the spruce trees.
Question- What would happen if earthquake waves were to interact with layers of the Earth?
Answer- Ok this is what really happens. As you may know there are seven tectonic plates on earth. Deep in the layers of earth energy is being build up to create a movement for thease plates. When the plates move it causes earthquakes but the thing is it depends were you are. If youre far from the movement you will get a small earthquake a small earthquake meaning you wouldnt even feel it, but on the other hand if your right by the movement you will get effected. Take calafornia as an example do you wonder why there are so many earthquakes happenening it because calafornia is right on the action! Calafornia is located right at the rigget place of the tectonic plate were the movement is big!

A. yellow
The yellow xanthophylls are the next most soluble, followed by the blue-green chlorophyll A. The least soluble pigment is the yellow green chlorophyll B. You may be wondering why plants have more than one pigment.
A tumor that invades surrounding tissues, is usually capable of producing metastases, may recur after attempted removal, and is likely to cause death unless adequately treated.
