Answer:
bone marrow
Explanation:
These are the blood cell-forming adult stem cells found in bone marrow. Every type of blood cell in the bone marrow starts as a stem cell. Stem cells are immature cells that are able to make other blood cells that mature and function as needed. These cells are used in procedures such as bone marrow transplants.
 
        
                    
             
        
        
        
Answer:
A. Cyanobacteria.
Explanation:
Both cyanobacteria and plants use water as an electron donor for the light phase of photosynthesis and make ATP and NADPH. The ATP and NADPH are used in the Calvin cycle to fix the atmospheric CO2 into glucose. The use of water as an electron donor releases oxygen gas as a by-product. This photosynthesis wherein the use of water as an electron donor releases oxygen gas as a by-product is also called oxygenic photosynthesis.
 
        
                    
             
        
        
        
The question is incomplete as the image and options are not given, however, the correct image and options are as follows:
A. If liquid Material A is in contact with gaseous Material A and the volume of the gas increases, the gas’s temperature will increase.
B. If liquid Material A is in contact with gaseous Material A and the volume of the gas increases, the gas’s temperature will decrease.
C. When the temperature of gaseous Material A increases, its volume will increase.
D. When the temperature of liquid Material A increases, its volume will increase.
Answer:
The correct answer is - C. When the temperature of gaseous Material A increases, its volume will increase.
Explanation:
The figure and table related to the given question are attached with the answer that shows the volume change during the time period in relation to temperature and the phase of material also changes with an increase in temperature. 
According to Figure 1, it is clear that initially, Material A was in the liquid phase and after a certain temperature, it is constant at a phase of a mix of liquid-gas and finally entirely in the gas phase from Time 22 sec to Time 24 sec. as temperature increased and the volume of Material A also increased according to the table 1.
So the hypothesis C is correct.
