Answer:
![5 * 10^{10}](https://tex.z-dn.net/?f=5%20%2A%2010%5E%7B10%7D)
Explanation:
The question is not complete. Remaining part of the question is as follows - Minimal growth medium for bacteria such as E. coli includes various salts with characteristic concentrations in the mM range and a carbon source. The carbon source is typically glucose and it is used at 0.5% (a concentration of 0.5 g/100 mL). For nitrogen, minimal medium contains ammonium chloride (NH4Cl) with a concentration of 0.1
g/100 mL
How many cells can be grown in a 5 mL culture using minimal medium before the medium exhausts the carbon?
Solution -
We will first find the mass concentration of 0.5 g/100 mL of solution.
gram per ml of glucose
The chemical formula of glucose is ![C_6H_{12}O_6](https://tex.z-dn.net/?f=C_6H_%7B12%7DO_6)
The molecular weight of glucose molecule is
grams per mole
Now, we will find the number of moles of glucose in a 5 ml medium -
mole
The number of carbon atom in each glucose molecule is equal to six, thus, number of minimal carbon mole is equal to
mole
Number of carbon atoms is equal to
Carbons
One bacteria has
carbon molecule.Thus,
ml medium will have
bacteria
Answer:
The correct answer is b. organ transplantation between species.
Evolutionary relationships between two species tell us about how close these species are, their common ancestors, similarity in DNA sequences, conserve sequences etc. Hence, one must have the knowledge about evolutionary relationships when considering the organ transplantation between two species.
On the other hand, for illustration of plant leaf, one must have the knowledge of plants anatomy instead of evolutionary relationships.
Similarly, blood donation within the same species demands the knowledge about blood groups or cell biology rather than evolutionary relationships.
Lastly, for studying DNA sequence of an insect may require the knowledge about genetics, bioinformatics etc.
It would read as GATACA. This is not the correct sequence and code, so an incorrect protein is made. It is a change in DNA when a is copied. This could happen under ultra-violet rays and other environmental factors.
