Answer:
grasses and shrubs to guanacos to pumas
Answer:
The correct answer is the third statement.
Explanation:
To hold the bodies together, to keep them incline, and to permit for movement, all the animals require support structures. There are three kinds of support systems found in animals, that is, exoskeleton, hydrostatic skeleton, and the endoskeleton. Of the mentioned support systems, the hydrostatic skeleton is used by worms for movement.
In the worms, a fluid-filled cavity known as coelom, and the fluid known as coelomic fluid is found between the muscles and the digestive tract. This coelomic fluid works as a hydrostatic skeleton. In worms, movement takes place by contraction of muscles that compress the coelomic fluid, that is, the watery body fluid resulting in the change in body composition.
Answer:
<em>X Free nitrogen is in the atmosphere
</em>
<em>Y Producers absorb nitrogen compounds through their roots.</em>
Explanation:
Nitrogen is present in the soil. The plants take up nitrogen along with other minerals as they draw water from the soil. Nitrogen enters the soil when decomposers feed on dead and decaying matter. They breakdown nitrogen and release it into the soil. The plants take this nitrogen from the soil.
The area labelled X shows that nitrogen is present in the air. Nitrogen is one of the abundant gases which is found in the Earth's atmosphere.
Answer:
a. Tibia
b. Fibula
c. Talus
Explanation:
The ankle joint consists of three bones: the fibula, the tibia and the talus. The first two make up a vault in which the dome of the third fits. It allows, above all, forward and backward turning movements, which are flexion and extension movements of the foot. In the lateral sense, the tops of the peroneal maleolus and tibial maleolus, which are the two bony appendages that continue fibula and tibia on both sides and downward, prevent a complete movement of lateral rotation although they do allow their onset.
The talus rests on the calcaneus (the bone that forms the heel) forming a fairly flat joint, without great movement. This subastragaline joint is a source of conflict as it supports the transmission of body weight forces and governs fine movements of foot stability. When the cartilage of this joint deteriorates, an arthritic degeneration and pain occurs, which sometimes forces surgical intervention to suppress or relieve it.
Through air in much the same way as water waves travel through water. In fact since water waves are easy to see and understand they are often used as an analogy to illustrate how sound waves behave.
