Yugi gagarin as the Soviet beat us in the space race
A red blood cell, starting from the heart's right atria is a deoxygenated red blood cell containing unoxygenated hemoglobin or carbaminohemoglobin (since it contains carbon dioxide instead of oxygen). This gives deoxygenated blood its chocolate-brown color. This red blood cell will be pumped to the right ventricle through the tricuspid valve then to the pulmonary circulation through the pulmonary valve. In the pulmonary circulation, there will be gas exchange in the alveoli of the lungs wherein carbon dioxide will dissociate from the hemoglobin and will be replaced with oxygen. Hemoglobin will now be called oxyhemoglobin and this gives oxygenated blood its bright red color. Hemoglobin in red blood cell can hold up to 4 molecules of oxygen. Now, from the pulmonary circulation, the red blood cell will go to the left atria through the pulmonary veins then to the left ventricle through the mitral valve then to the aorta and systemic circulation through the aortic valve. In the systemic circulation, oxygen is replaced by carbon dioxide (end-products of cellular respiration) and then will be transported back to the heart, particularly in the right atrium. This is called the cardiac cycle.
The answer here is D because it covers the other options namely A and C while B is not really true.Multi cellular organisms are made up of billions of cells each specialized to a unique role and these cells are organized into structural and functional units such as tissues and organs.For each cell and organ to function optimally, it requires oxygen and nutrients and needs carbon dioxide and metabolic waste taken away in a continuous, never ending process.A mechanism is needed to accomplish the important function of transporting the relevant materials to and from the cell. The circulatory system fits this bill splendidly. It is a specialized organ system which allows blood and lymph to flow through the entire body carrying nutrients such as glucose, amino acids and electrolytes as well as oxygen to each cell, at the same time carting away carbon dioxide and all sorts of metabolic waste over to excretory organs to be expelled from the body.
Answer:
producers
Explanation:
producers are organisms such as plants that use energy from the sun to produce their own food through photosynthesis
Answer:
Each daughter cell contains the same genetic makeup as the original parent cell
Explanation:
After the process of mitosis and cell division 2 new identical daughter cells are created. Each daughter cells contains the same number of chromosomes as the original cell. Therefore, each daughter cell has a complete copy of all the genes that the original cell contained. Making them identical to the original cell.
