Ans.
An electron carrier is defined as a molecule, which is capable of receiving one or more electrons from an electron donating molecule (electron donor). In given figure, molecule NADP (nicotinamide adenine dinucleotide phosphate) is acting as an electron carrier that accepts electrons form chlorophylls and form NADPH.
Thus, the correct answer is 'option C). NADP.'
I think the answer is probably A because the population will eventually start to reproduce

Answer:
585ml
Explanation:
13 fold means that volume of the diluted solution is 13 times higher than the volume of the stock.
It means you have to perform 1:13 dilution
D f = Vdiluted/ Vstock
Vdiluted = 13 × Vstock
Vdiluted = 13 × 45ml
Vdiluted = 585ml
You will need to add enough water to the stock (MgSO4) solution till it gets to a total volume of 585ml
Answer & Explanation: Cholera as a disease is any of the several acute infectious diseases of humans and domestic animals caused by certain strains of the Vibrio cholerae bacterium.
a) It is unlikely to spread directly from one person to another. So the risk of becoming ill through casual contact is quite low. However, for those with weakened immunity, they could possible contract the disease on contact leading to infection.
b) Signs of infection is usually marked by severe gastrointestinal symptoms such as diarrhea, abdominal cramps, nausea, vomiting and dehydration
c) Some of the different ways the disease could be spread include ingestion of contaminated water. Bacteria present in the faeces of an infected person are usually the main source of contamination.
