You can’t taste food without saliva
T
In order for food to have taste, chemicals from the food must first dissolve in saliva. It’s only once they’ve been dissolved in a liquid that the chemicals can be detected by receptors on taste buds. During this process, some salivary constituents chemically interact with taste substances. For example, salivary buffers (e.g., bicarbonate ions) decrease the concentration of free hydrogen ions (sour taste), and there are some salivary proteins that may bind with bitter taste substances.

The two basic types of scientific investigations?
Experiments- organized procedures used to study something, under controlled conditions.
Observations- process of gathering information by using the senses.

Describe Supply and Demand?
The law of supply and demands states that when the demand for a product increases while the supply remains fixed , the cost of the product will increase.

An individual blood cell takes about 1 day to make a complete circuit of the body
F -------60 seconds
You have about 5 liters of blood in your body (at least, most people do) and the average heart pumps about 70 mL of blood out with each beat. A healthy heart also beats around 70 times a minute. So, if you multiply the amount of blood that the heart can pump by the number of beats in a minute, you actually get about 4.9 liters of blood pumped per minute, which is almost your whole body’s worth of blood. In just a minute, the heart pumps the entire blood volume around your body.

What is the difference between renewable and non renewable resources ? Provide 1 example for each
Non-Renewable Resources...These are resources that, can’t be replaced or will take millions of years to replace.
EX: oil, coal
Renewable Resources These are resources that ,Can be replaced by a natural process in a short amount of time.
EX: water, wind

It’s impossible to burp in space_____
True
When you burp on Earth, gravity keeps down the solids and liquid from the food you just ate, so only the gas escapes from your mouth. In the absence of gravity, the gas cannot separate from the liquids and solids, so burping essentially turns into puking.
