1. Amylase, produced in the mouth. It helps break down large starch molecules into smaller sugar molecules.
2. Pepsin, produced in the stomach.
3. Trypsin, produced in the pancreas.
I'm probably wrong. Sorry.
Cameras and video-shooters are essentially tough. They can withstand a lot, from insects to shark bites. However, in order to withstand being outside for such a long time of three years? That's a little tricky.
As we all know, the batteries can corrode if left in damp places, or if left in for too long. Therefor, this can't be damp. Nowadays, most cameras have plastic in various places, so leaving it somewhere hot could inevitably melt it. You don't want that. If your camera is left in the cold, (18°F, 10°C) then the batteries could be severely changed. If left in a cold place, the battery life could deplete by so much as half, so in very cold climates, you will very quickly run out of power.
In order for it to sustain 3 years, you will probably need to find a climates that is about 60°F (15.5556°C) in a drier location.
I hope this helped!
If the father had the gene BB (purebred & not carrying colourblind allele), then the answer will be a). All of their children will have normal vision with half of them carrying the colourblind allele.
If the father had the gene Bb (hydrid & carrying colourblind allele), then the answer will be d). 3/4 of their children would have normal vision whilst the last quarter would have colourblind males. This is due to them having to receive one colourblind allele from their mother on the X chromosome & one colourblind allele from their father on the Y chromosome.
C. They produce ATP
The energy required for various chemical activities needed for life is released by the mitochondria in the form of ATP.
