1 answer:

6 0

She feels the pain because the signal in her injured finger pick up the message and pass it to the spinal cord, the synapses of neuron within the spinal cord pass the message to the thalamus region of the brain which then relay the message to various areas of the brain's somatosensory cortex, which then send pain signals back to the hand.

Which nitrogenous bases pair with each other? What type of hydrogen bond forms between them?

dolphi86 [110]

Answer:

Base pairs occur when nitrogenous bases make hydrogen bonds with each other. Each base has a specific partner: guanine with cytosine, adenine with thymine (in DNA) or adenine with uracil (in RNA). The hydrogen bonds are weak, allowing DNA to 'unzip'.

A student observes 5,000 RFUs in a 200μl aliquot from a G3-500 ml culture. How many total RFUs will be present in a G3-15ml samp

natka813 [3]

Answer:

The maximum no. of RFUs collected in the purification procedure $= 3.05 \times 10^5$ RFUs

Explanation:

No. of RFUs in a 200 ul (0.2ml) aliquot = 5000 RFUs

So, No. of RFUs in G3-500 ml culture $= 5000 \times \frac{500 ml}{0.2 ml}$ RFUs

$= 5000 \times 2500$ RFUs

$= 1.25 \times 10^7$ RFUs

Similarly, No. of RFUs in a G3-15ml sample $= 5000 \times \frac{15 ml}{0.2 ml}$ RFUs

$= 5000 \times 75$ RFUs

$= 3.75 \times 10^5$ RFUs

The maximum no. of RFUs collected in the purification procedure

$= 3.75 \times 10^5 \times 80$ % RFUs

$= 3.75 \times 10^5 \times 0.80$ RFUs

$= 3.05 \times 10^5$ RFUs

It presents a pressure which makes ventilation difficult, it cause the same effects as a one way valve.</span>
