Answer:
It takes place in the Stroma
Explanation:
Answer: By losing its two outermost electron
Explanation:
Calcium is a element that belongs to group 2 in the periodic table. It has an atomic number of 20, and an electronic configuration of 2, 8, 8, 2.
Hence, to form an octet structure, it gives off its two electrons as shown below:
Ca <----> Ca2+ + 2e-
Thus, by losing its two outermost electrons, a positively charged calcium ion (Ca2+) is formed
Let's think about this question and ask our selves what is life?
Think about a non-living thing, like a bike.
Does this bike have kids? Does it need to eat or sleep? What is it made up of? What does it need to survive? Does it need to be able to sense the environment around itself?
You're probably saying, no the bike doesn't do a lot of these things.
Humans, animals, and pretty much all living things need to perpetuate their genes by means of reproduction, whether it is asexual or sexual.
We need to animals need to eat and sleep, but you can just categorize this as a metabolic process. Plants need Nitrogen and CO2 and sunlight, to undergo metabolic processes and make glucose (another metabolic process). We also must be able to maintain an equilibrium while conducting metabolism (homeostasis).
We need to be able to sense the environment around ourselves to survive.
If you look at simple organisms, they are often able to detect different chemicals and know to be attracted or stay away from certain substances.
All living things are made up of cells.
George's doctor will need to culture the isolated S. aureus to determine if the isolated bacterium is the one responsible for the infection.
<h3>What is Koch's postulates?</h3>
Robert Koch was a famous microbiologist that made some postulates as follows:
- The bacteria must be present in every case of the disease.
- The bacteria must be isolated from the host with the disease and grown in pure culture.
- The specific disease must be reproduced when a pure culture of the bacteria is inoculated into a healthy susceptible host.
- The bacteria must be recoverable from the experimentally infected host
According to this question, S. aureus has been isolated from George’s infected wound.
This means that in accordance with Koch's postulates, George's doctor will need to culture the isolated S. aureus to determine if the isolated bacterium is the one responsible for the infection.
