What must happen to the liquid as it passes from the stomach to the small intestine for digestion?

1 answer:

4 0

The liquid should be neutralized.
In the stomach, the pH value is around 2.0, which is because of the hydrochloric acid in the stomach. It can provide a optimum pH for the stomach enzymes.
However in the small intestine, the enzymes there works in a optimum pH of around 8.0, therefore the liquid must be neutralized before going into the small intestine, or else the enzymes in the small intestine will be denatured due to extreme pH.
Neutralization can be done by the sodium hydrogen carbonate, which is a alkali produced in small intestine.

A researcher recorded that a chemical reaction required 2.90 gal water and raised the temperature of the reaction vessel by 57 F

Bess [88]

<em>A. 11.0 L is the researcher's volume measurement to the SL units of liter</em>

<u>Explanation:</u>

Given that a researcher recorded that the chemical reaction has water = 2.90 gallon.

We have to convert the researcher's volume into the SL units of liter.

<em>So, we know that 1 gallon = 3.875 liters</em>.

Then we have to convert 2.90 gallons of water in to liters.

Then , volume in L = $(volume\ in \ gal) \times (3.875 L/1 gal)$ = $(2.90) \times (3.875L/1 gal)$

= $11.0L$

<em>Then the required volume in $L= 11.0L$ </em>

podryga [215]

Answer:

<h2>False</h2>

Explanation:

Natural killer cells (NK cells) are a type of lymphocyte and also a component of innate immune system. NK cells play various functions in immune system and they play a major role in the host-rejection in virally infected cells.

NK cells are activated in response to interferons and also by various other responses. NK cells work to by secreting IFNγ and TNFα. Natural killer cells play a very important role in early host defense against viruses.
