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:
The reason why animals <u>cannot synthesize oxaloacetate</u> is because the fatty acids which they produce, are not able to create glucose (oxaloacetate).
Explanation:
The fatty acids in animals need to be converted to acetyl-CoA first, but this acetyl won't convert into oxaloacetate, in comparison to plants, that use the glyoxylate cycle, that allows them to produce the mentioned glucose.
Answer:
The cascade amplifies the cellular signal, thereby receptor activation lead to potent responses
Explanation:
Usual signal transduction is produced by protein phosphorylation, this posttranslational modification activates signal transductors in order to bind receptors and ligands. In multicellular organisms, the signal transduction pathways regulate critical cellular processes including, for example, cell communication
Answer:
6,500 mL
Explanation:
We are asked to find the total volume of air that effectively entered to the alveoli in one minute so that oxygen could be exchanged for carbon dioxide and leave the body through exhalation.
The problem says that the normal breathing rate is 10 breaths per minute, and for each breathe it takes 800 mL of air. But not all air enters the alveoli because it says there are 150 mL that are not effectively used by the alveoli. Therefore, the net amount of air used in each breathe is 800 ml - 150mL, giving us a total amount of 650 mL of air.
Now that we have the net amount of air for each breathe, we have to multiply it by the total breaths a body makes in one minute. In this case, the breathing rate is 10 breaths/min.
So, to obtain the final answer we just need to multiply the amount of net air per breathe (650 mL) times the number of breathes in one minute (10 breathes); that is 650 mL/breath x 10 breaths and gives us 6,500 mL.
I think the correct answer would be a-substitution
