Answer:
Digestion
Explanation:
The breakdown of foods into forms that can be transported to cells and absorb into these cells(this process has two parts): Mechanical(breaks down large pieces of food into smaller ones) and Deglutition(swallowing).
Answer:
Forelimb protraction starts with a rapid flexion of the shoulder joint bringing the humerus close to its maximum cranial rotation angle, almost in parallel to the mid-sagittal plane. This position has already been reached by the middle of the swing phase.
Commensalism is when one organism benefits off the other one without harming it. Examples are tree frogs that use plants for protection or jackals that have been expelled from packs trailing tigers and feeding on the remains of its kill. Barnacles on whales get shelter by attaching to a whales body
Carbon dioxide hopefully I think ❤️
Answer:
The horses developed an oxygen debt when they exercise because they suffered from Exercise-Induced Pulmonary Hemorrhage (EIPH).
Explanation:
A temporary shortage of oxygen in the body tissues during physical exertion such as exercise or a sudden burst of activity is referred to as oxygen shortage.
Horses (compared to humans) are uniquely designed to experience little or none of this.
When the body takes up oxygen, it reacts with glucose to produce energy. This is called Aerobic respiration.
There is also another procedure that the body uses to produce energy. This occurs when glucose is broken down in the cells. After this happens, lactic acid is created but cannot be stored in the body and must be expelled.
This interval when energy is produced without the presence of oxygen is called "oxygen debt".
When a horse is fit, its breathing quickly returns to normal. The longer the time taken for the breathing to return to normal, the less fit the horse is.
One of the factors that can reduce the fitness of a horse is the Exercise-Induced Pulmonary Hemorrhage (EIPH).
This occurs when blood vessle in the lung ruptures causing blood to bleed into the airways. So blood occupies space where oxygen should have. This reduced the amount of oxygen delivered to the blood stream. Hence the oxygen debt takes longer to be repaid.
