Hitman42 [59]11 months ago
4 0

E.coli Bacteria present in one CFU at 9:00 pm = 1.07 X 109 bacteria and E.coli at 11:00 am = 1 generation time. That means 2.66X 10^ 9 cells per 1 CFU.

The average CFU in probiotics is between 1 and 10 billion CFUs per serving. To find out the number of CFU in the sample then the number of colony forming units on thee countable plate is multiples by 1/FDF. For example when the countable place has 200 colonies then 200 CFU and the FDF was 1/4000.

CFU measures the viable cells.High number of E.coli bacteria in water indicates that contaminated by feces. and it increasing the risk of exposure to pathogens that causes illness.

An action potential triggers the release of synaptic vesicles into the synaptic cleft by _____ channels, allowing _____ ions to
noname [10]

Answer:

1. opening Voltage gated channels

2. Calcium

Explanation:

The signals are transmitted in the neurons in the form of electrical signals and which are transformed into the chemical signals at the synaptic cleft.

The electrical signal is transformed into a chemical signal when the electrical impulse reaches the terminal of the axon and opens the calcium voltage channels. The calcium which is present in a higher amount than inside enter into the terminal and allows fusion of the synaptic vesicle carrying neurotransmitter and the neurotransmitter is released into the synapse.

The neurotransmitter then binds the receptors and initiates the electrical impulse in the postsynaptic neuron.

Thus, opening Voltage gated channels and Calcium is the correct answer.
