Once inside muscle cells, the oxygen can either bind to myoglobin (a protein like hemoglobin that enables muscle cells to store a small amount of oxygen) or enter the mitochondria to be used in the elec- tron transport chain to accept the H+ ions produced by the oxidation of carbohydrate and fat.
Soz if its not very clear, but if u get it correct, can u give me brainly?
Answer:
The correct answer is " two cardiac muscle cells are connected by gap junctions".
Explanation:
Intercalated discs are microscopic features seen in the microscope as cardiac fibers, found between the myocardial cells of the heart. These features correspond of two cardiac muscle cells connected by gap junctions. The intercalated discs allow the interconnection of multiple cardiac cell muscles to work simultaneously as a single functional organ or syncytium.
Answer: artery
Explanation:
The artery is the blood vessel that carry oxygenated (oxygen-rich) blood away from the heart while the vein carry deoxygenated(oxygen-poor) blood from the body to the heart.
Hence, all arteries carry oxygenated blood except pulmonary artery while all veins carry deoxygenated blood except pulmonary vein.
Every single one here looks correct except for the last one involving algae, frog, and rabbit considering they are organisms, therefore it should be organism.
