Since you have apparently tried to answer the question here is my interpretation. I list the six pictures (numbered from top to bottom) and link four of them to an answer. 1 - yeast cells? 2 - ash tree section (c) 3 - rotifer (b) 4 - muscle fibre?? 5 - bacteria? (a) 6 - Leeuwenhoek's microscope (d) According to the WP page on van Leeuwenhoek he did ...

Who said they did not have the same problems? I'm sure they did and I'm sure most of them had horrible diarrhea. A quick google search brought up Man and Microbes: Disease and Plagues in History and Modern Times, by Arno Karlen which states that In 1817, when the first cholera pandemic began [...]. In Calcutta and Jessore, cholera killed 5,000 British ...

Answer clarified based on comment by @DurgaDatta What would it mean to say the enzyme activity was tested in vitro on the mutant? When we say the response of the a single gene knock out mutant, the cell should be intact except for lacing one gene, which would mean that the response is in vivo. The knockouts were performed inside the E. coli cells and, ...

It is possible to conduct an in vitro experiment with cell extracts. Meaning that you break up the cells and put their pieces into a reaction glass and do your experiment. It is assumed that the cell molecules (enzyme, sugar or cofactors) will still carry out their functions even though the cell is no more. In other words, you used the mutant to produce the ...

I am assuming in spacesuit here, on the face (lit side) of the moon. Bodily degradation involves much more than external fungi and bacteria. Cells that receive no oxygen or nutrients die. We talk of such tissue death as dry gangrene when it affects extremities, such as fingers, feet, etc. However, we also recognize gangrenous bowel, etc. which results in ...

Decay is a process where the body is digested by bacteria, fungi and other living things. The moon has no known biological processes and while its possible for some microorganisms to survive in space, I think its generally understood that the lunar surface would not support life in a significant way, especially if the body is in vacuum. Other processes ...

I actually doubt that the pectinase has such a broad pH range in which it works optimally. Searching the web I found two figures which support my doubts: The first is from an article ("Immobilization of pectinase by adsorption on an alginate-coated chitin support") which compares the activity of native and immobilized pectinase under different ...

The rhizosphere is the narrow region of soil that is directly influenced by root secretions and associated soil microorganisms (wiki) And endorrhiza (also termed Endomycorrhiza, AMS or AM) is a special case of the mycorrhiza, a mutualistic relationship between fungi and plant roots, where the fungus cells are stored within the root and not on its surface.
