Answer:
A
Explanation:
ECM proteins are significant in the development of the extracellular matrix which is responsible for supporting and connecting cells together in the formation of tissues. The extracellular matrix is also a major component of connective tissue that is composed of collagen fibers connecting tissues. Mutations of these proteins will result in connective tissue disorders such as scurvy, sarcomas, systemic lupus erythematosus (SLE) and etcetera.
The three domains are: Archaea, Bacteria, and Eukaryota. The six kingdoms are: Animals, Plants, Fungus, Protists, Archaebacteria, and Eubacteria.
Tiger sharks and seal populations are related because seals are the natural prey for tiger sharks. Which means where there are both seals and tiger sharks it works out as a predator prey situation. Also the seal population world be lower in that area.
Answer:
ii
Explanation:
Hemoglobin is responsible for distributing oxygen, and to a lesser extent, carbon dioxide, throughout the circulatory systems of humans, vertebrates, and many invertebrates. The blood is more than the proteins, though. Blood is actually a term used to describe the liquid that moves through the vessels and includes plasma (the liquid portion, which contains water, proteins, salts, lipids, and glucose) and the cells (red and white cells) and cell fragments called platelets. Blood plasma is actually the dominant component of blood and contains the water, proteins, electrolytes, lipids, and glucose. The cells are responsible for carrying the gases (red cells) and immune the response (white). The platelets are responsible for blood clotting. Interstitial fluid that surrounds cells is separate from the blood, but in hemolymph, they are combined. In humans, cellular components make up approximately 45 percent of the blood and the liquid plasma 55 percent. Blood is 20 percent of a person’s extracellular fluid and eight percent of weight.
The Role of Blood in the Body
Blood, like the human blood illustrated in
Figure 21.5 is important for regulation of the body’s systems and homeostasis. Blood helps maintain homeostasis by stabilizing pH, temperature, osmotic pressure, and by eliminating excess heat. Blood supports growth by distributing nutrients and hormones, and by removing waste. Blood plays a protective role by transporting clotting factors and platelets to prevent blood loss and transporting the disease-fighting agents or white blood cells to sites of infection.
