1. Ich gehen in die Sprachschule heute Abend.
Here’s part of the answer sorry don’t understand the rest
Answer:
When microbiological media has been made, it still has to be sterilized because of microbial contamination from air, glassware, hands, etc. Within a few hours there will be thousands of bacteria reproducing in the media so it has to be sterilized quickly before the microbes start using the nutrients up.
Media for growing bacteria and cells is sterilized before use to prevent the contamination of the desired culture with other types of bacteria or cells. The presence of undesired cells on culture media can lead to the failure of the culture or affect the results of future experiments.
Bacteria and cells are often grown on culture media to determine the presence or absence of specific bacteria or types of cells, such as pathogenic bacteria or abnormal cells that may indicate disease. Cells may also be cultured as part of an experiment to determine if a particular experimental factor has affected the ability of a bacterium or cell to grow. In both cases, the presence of microorganisms other than those that are intended for culture in the culture medium may cause the culture to fail, as the undesired bacteria or cells can out-compete the desired cells for the nutrients in the culture medium.

Answer:
(1) Kennen
(2) Wissen
(3) Kennen
(4) Wisst
(5) gewusst
(6) Kennen; kennt
(7) Weißt
Explanation:
The difference between <em>kennen</em> and <em>wissen</em> is tricky for English-L1 learners because they can both translate to the same "to know." (Interestingly, for native German speakers, they are semantically clearly delineated and there is absolute no confusion about when to use which.)
There are many websites listing hints on when to use which, but I find the following most useful:
Kennen: if you can replace it with "recognize" then it is likely a candidate for "kennen." For example, the first sentence in your problem "Do you know the saying?" --> "Do you <em>recognize</em> the saying?" (hence, use "kennen")
Wissen: you have "knowledge about something" For example, in the first sentence of your problem, if you plug in "Do you have knowledge about the saying" - that sounds clumsy, so "wissen" is not a good candidate (in contrast to the "recognize/kennen" test). But for sentence #2: "(do you have knowledge about) how many people live in Germany" - that sounds like a good fit, and "wissen" is appropriate.
Eventually, with practice you will be able to distinguish the two appropriately and quickly.
