The protein components which reside on the red blood cell membrane and which determines blood type are THE ANTIGENS.
Antigens are proteins molecules which are found on the surface of the red blood cell, the antigens that are present in the cell determine the type of blood that will be present in the individual. There are four types of blood; A, B, AB and O. <span />
Answer: for me the best option is D.
Explanation: lets explain this.
Cellular respiration begins with a process that divides the glucose within the cells making it readily available as a source of energy. This process can occur without oxygen (anaerobic respiration) or in the presence of oxygen (aerobic respiration). Anaerobic respiration generates more excess waste (lactate) than aerobic . Besides, high levels of lactate build within the muscle cells. Excess lactate slows the cellular respiratory process and is experienced as a burning sensation in the muscles if exercise continues.
The observation that indicates that it is a living thing that is multicellular because it has membrane-bound organelles. The correct answer is option B. Multicellular organisms' cells are macroscopic which are naked to the visible eye. These organisms are eukaryotic so this means that their cells contain membrane-bound structures.
