Final answer:
Healthy dogs and cats have clear and colorless plasma, while horses and cattle have clear and light-yellow plasma, with the coloration attributed to proteins and other substances in the plasma.
Step-by-step explanation:
Plasma from healthy dogs and cats is typically clear and colorless, whereas plasma from horses and cattle is often clear and light-yellow. Plasma is the fluid part of the blood that is left after filtering out all the blood cells. It is made up of approximately 90% water and contains dissolved proteins, glucose, ions, hormones, and gases. While blood plasma is mostly water, the yellowish tint it can have is due to the presence of certain proteins and substances. In contrast to plasma, serum is the component of plasma that lacks blood coagulation factors. Overall, the color and clarity of plasma can vary slightly depending on the species of animal.
Plasma is the fluid part of blood, which is about 90% water and about 10% dissolved proteins, glucose, ions, hormones, and gases. Blood is made up mostly of plasma. Since plasma contains various substances, it can have different appearances in different animals.
