Answer:
Hemoglobin is responsible for binding and transporting oxygen in the body. It is a tetrameric protein that is found in high concentration in red blood cells (erythrocytes, red blood cells). Each hemoglobin molecule is made up of four subunits: two of the alpha type and two of the beta type, and each subunit can bind an oxygen molecule through its heme group.
Structure studies have shown that hemoglobin can adopt two conformations, called T (tense) and R (relaxed). Deoxyhemoglobin (in blue) is in state T, and the union of oxygen (in red) causes the transition to state R. The animation shows a close view of the heme group (in white, balls and rods) of one of the subunits of hemoglobin. In the deoxygenated state (T), the iron atom is not coplanar with the rest of the heme group due to its association with the histidine side chain. The union of oxygen displaces the iron atom so that it remains coplanar with the rest of the heme group, which in turn drags histidine, producing a larger-scale conformational change that affects the entire protein.
Hemoglobin can be considered as a tetramer formed by two alpha-beta dimers. The conformational change associated with the transition from T to R mainly affects the relative position of these two dimers (rather than the interactions between the alpha and beta subunits within a dimer). This is illustrated in the last stretch of the animation (drawn in black and white).
The best answer would be, 'The warmer the air temperature, the greater the humidity.'
The second choice is true, but the graph is representing humidity, not precipitation. That is off-topic.
C could also be true, but the chart didn't refer to any body of water.
I hope this helped you!
Brainliest answer is always appreciated!
They re called granum singular and grana plural
Answer:
I think stream bank. It grows in moist places and wetlands, and is especially abundant along streamsides and riparian areas at elevations below 1400 m.
Explanation:
What are you asking for here? we need a solid question not a statement.
i'd say that the statement is true. we cant define life because we do not know what life, in essence, is. we can define, however, the characteristice of all living things:
Movement
Respiration
Sensitivity
Nutrition
Excretion
Reproduction
Growth
MRS NERG
