Please explain why mendel rejected the blending inheritance theory?
Please define Mendel's principles of inheritances?
in my teachers book (probably misstranslated from english, and she achieved her doctors degree with this work of copying) she says :
bacteria : the free transportors of electrons (not binded to de membrane) are : nicotine adenine dinucleotide and nicotinamide adenine dinucleotide phosphate, the couples NAD/NADP and NADP/NADPH , and they have a redox potential of -0,320, respectively, -0,324 V
As far as I know NAD is reduce to NAD^+/NADH and NADP is reduced to NADP^+/NADPH
I dont understand what „couples” mean here... and to be fair they are so strangely coupled i dont even believe that this is a correct association
Please, help me learn and not to learn without any logic!
Thank you very much and deeply grateful in advance
Which of the following statements is true

Hi.We know there are some cells in bone tissue that is called osteoclast. Osteoclasts produce a number of enzymes to cleave and dissolve bone matrix . Now the question is that : why these enzymes don't hurt the Osteoclasts and its membrane? Which function protect osteoclast against these enzymes?
Thanks .

Use online bioinformatics tools, and search the scientific literature to answer the following questions
1. What is this protein? (name, function from blast search)
3. Can you make a prediction of its function? What evidence supports this prediction?
5. If the protein occurs in other organisms, can this information be used to glean further, more specific information on the function of the protein?
6. How similar is your query sequence to other homologous sequences – present this information as an alignment of relevant sequences, and use these sequences to construct a phylogenetic tree (use Clustal omega).
