Combine the following:
· 80g NaCl
· 2g KCl
· 14.4g Na2HPO4 (dibasic anhydrous)
· 2.4g KH2PO4 (monobasic anhydrous)
· 800mL distilled H2O
1. Adjust pH to 7.4 with HCl
2. Add H2O to 1L
3. Autoclave for 20 minutes on liquid cycle. Store at room temperature.

1.) Adjust pH to 7.4 with Hcl
2-) Add H2O to 1 litre
3.) Autoclave for 20 minutes on liquid cycle store at room temperature. Which ions are being produced by this process, assuming that each of the chemical compounds dissociate into their constituent parts once they are dissolved in water?
Describe how do plants get carbon in form of CO2 from the air
In Persian cats, the allele for long hair is dominant. If all the Persian cats are born with
long hair, (A) What are the two possible genotypes of the parents? (B) If the offspring of
the first cross results with 3⁄4 long haired while 1⁄4 are short haired. Can you now determine
the exact parents?

Using CHI square test,determine whether the ponderosa pine tree at Glacier Lake conform to be Hardy-Weinberg equilibrium at the peroxidase locus?
Why is the concentration of urea higher in the urine than in the filtrate?
The processes that result in the glucose concentrations?
When a nerve impulse passes from one neuron to another, it causes the release of neurotransmitter from versicles a fused to the membrane of the synaptic knob. Neurotransmitter is released into the synaptic cleft and then binds to receptor on the ion channel. How does this lead to setting up an action potential in the next neuron?
The immune systems Primary role is to defend against pathogens. For this to be affective the immune system must be able to recognise cells that belong to the body and cells that do not.
What is the mechanism that the immune system uses to distinguish between body cells and potential pathogens?
why is this mechanism means that patients who receive and organ donation require immune suppression drugs?
