Pls send me answer of this question briefly i will give you like sure sir   • You and your roommate are watching the track and field events at the Olympics. One of the sportscasters mentions that a particular athlete has been banned from competing because he was found guilty of blood doping. Your roommate asks you what blood doping is and why the athlete would be banned for doping his blood. How would you answer your roommates’ question?

please choose only one option i can only choose one

There are 4 basic tissues in the human body. For each of the following organs/structures describe the location and function of at least three basic tissues found in them. Heart and stomach You have received GHS 1 million as a scientist to develop a vaccine for corona virus. You have been able to develop the vaccine but now the challenge is how the vaccine will enter the cells of the body when you inject it. From your knowledge of the structure of the cell membrane give and explain 2 features you can exploit in order for the vaccine to go across the cell membrane into the cell.

6 of 20 Plasma albumins primarily function in the body's defence transport certain proteins in the blood transport iron in the blood contribute to the clotting process maintain the blood's osmotic pressure

i found this past paper however i cannot find the solutions, please can you answer question 1c

*** fluorescence in bleached area- BLEACH WITH LASER BEAM bleach Protein 1 bleached area RECOVERY Figure 10-13 Molecular Biology of the Cell 6 (Garland Science 2015) Protein 2 *** ** *** time The diffusion/exchange rate of a protein can be measured by photobleaching techniques such as FRAP. When there is protein exchange (i.e. if the protein is mobile), fluorescence recovery in the bleached region occurs, as shown in the figure above. The graphs below show the fluorescence measurement of an area in the cell before and after bleaching for protein 1 and protein 2. Which protein has lower mobility? Protein 1 Protein 2 fluorescence in bleached area->> fluorescence in bleached area bleach BLEACH time RECOVERY time
