Answer:
42,5 mL
Explanation:
We need to use the serial dilution formula beacuse we start with a stock concentrate solution and we need to prepare a new less concentrated one.
<u>DF in the dilution factor, Vi is the initial volume and Vf is the final volume.</u>
The first step is to have the same measurment unit so we need to convert 345 µg to mg.
we know that 1 µg equals 0,001 g, hence:
now the final volume is 0,345 mg protein/ mL and the inital volume is 15mg protein/mL, both of them are in the same unit so we can use the formula
Now since the question said that we already have 1.0mL of the amylase stock solution we need to subtract that 1.0mL to the 43,5 mg protein/mL
So, we need 42,5 mL of diluting buffer if we want a final concentration of 345 µg protein/mL (0.345 mg protein/mL)

Answer:
Chemical digestion actually starts in the mouth when our saliva mixes in with the food. So, A. wouldn't really be correct. It's not the molars that are doing the chewing, but rather your jaw muscels. I don't even know what pepsin is... <u>C. would probably be your best bet because it's your saliva that breaks down your food and helps you chew it.</u> And D. your tongue just helps to move the food around...

Answer:
les glandes produisent deux produits essentiels :
-gamètes. les mâles produisent du sperme et les femelles produisent des ovules (œufs). la formation des gamètes dépend d'un type particulier de division cellulaire appelé méiose
-hormones sexuelles. ces hormones stéroïdes - principalement la testostérone chez les hommes, les œstrogènes et la progestérone chez les femmes - jouent un rôle vital à la fois dans le développement et la fonction des organes reproducteurs et dans le comportement et les pulsions sexuelles. ces hormones influencent également la croissance et le développement de nombreux autres organes et tissus du corps
