Which one of the following represents the correct order through which food passes in the alimentarycanal:
konstantin123 [22]

Answer:

D) Mouth, pharynx, esophagus, stomach, small intestine, large intestine.

Explanation:

Food is ingested in the mouth, passes through the pharynx that connects the mouth to the esophagus. It moves down the esophagus by parastalsis. It is further digested in the stomach, absorbed in the small intestine and indigestible material together with fibre is passed to the large intestine where its either digested by freindly bacteria or eliminated as waste by defecation.

Your friends are worried because their newborn sleeps 16 or 17 hours a day. what would you tell them?
just olya [345]
It may be perfectly healthy that their newborn is sleeping this long so unless they start displaying other strange symptoms that cause concern, there is no need to worry. They could suggest that they are concerned to the midwife if they feel anxious, to get a professional opinion.

You inoculate two tubes of liquid culture medium with 100 bacterial cells and incubate one tube at 37°C and the other at 55°C. A
Nady [450]

Answer:

thermophile.

Explanation:

A thermophile is a kind of bacteria that belongs to the Archaea Domain and they are the kind of animals that can live in a region of high or extreme temperature. There has been a research on a kind of thermophile which is known as Methanopyrus kandleri which can exist in an extreme temperature of up to 500° C.

So, if we take a look at the question again we can see that after 48 hours and at 37°C 20,000 bacteria per milliliter are already in the tube and at more higher temperature of 55°C we have 1,568,000 bacteria per milliliter which means that at higher temperature more of the bacterial is produced.

Marrrta [24]

The sodium hydroxide solution and vegetable oil underwent a chemical change.

<h3><u>Explanation:</u></h3>

The reaction between a base and a fat or fatty acid is called as saponification reaction. Here the base dissociates into the cation and hydroxyl ion. The hydrogen from the fatty acid of the oil reacts with the hydroxyl ion to form water which is basically the neutralization reaction. This cation now reacts with the rest of the fatty acid to form a bipolar molecule which is the soap. During the reaction, the solution becomes cloudy but with time, it again goes back to solution. The cloudyness appears because oil isn't soluble in water based solutions and the base is actually made solution in water.

Here the sodium hydroxide reacts with oil to form water and the soap molecule which is a chemical change.
