Tropical rain forest are one of the important biomes of the world that is characterized by a short or no dry season and a precipitation of overall 60 mm each month. They are also known as lowland equatorial evergreen rainforest. If we talk about location, they mostly are found between fall between the Tropic of Cancer and the Capricorn since they lie near to equator and they receive sufficient amount of sunshine and rain.
Due to their location near the equators, they receive greater amount of sunshine than other biomes and when sunshine is greater the rate of water evaporation is also greater that results in more rainfall.

Answer: Yes, they would either need a blood relative to take DNA samples from or something the deceased had before their death such as a baby tooth or hair.
Salivary amylase will be active for only an hour or so because the optimum pH for activity of amylase is about 6.7–7.0 which is available in the mouth but the pH of the stomach is acidic around 1-2 due to which the amylase enzyme becomes inactive in short-time.
The lingual lipase enzyme is present in the saliva but isn't active until reaching the stomach because this enzyme is acid stable and works efficiently in the stomach, not in the mouth.
Amylase enzyme is secreted in the mouth and is responsible for the breakdown of starch in food into sugars and it starts acting as soon as we put food in the mouth whereas Lingual lipase enzyme is secreted along with saliva but it is not active in the mouth rather its activity starts in the stomach which is responsible for the degradation of triacylglycerol molecules.

Answer:
When red blood cells are placed inside pure water they normally swell up and eventually explode. Red blood cells in pure water swell up because the pure water enter in the red blood cells by mean of osmosis. The water molecules are able to enter the red blood cells because the salt concentration inside the red blood cells is more than that of the pure water.
As water continue to move inside the cells, the cell swell up and eventually burst because the internal pressure inside the cell is greater than the external pressure, therefore the cell membrane become ruptured and eventually burst.
